In 1961, the First Robotic Arm Punched In


That success will be traced partially to Kim, now an emeritus professor at KAIST. Of common peak, with grey hair since his mid-30s, he was the primary professor in South Korea to systematically train semiconductor engineering. From 1975, when the nation had barely begun producing its first transistors, to 2008, when he retired from educating, Kim skilled greater than 100 college students, successfully creating the primary two generations of South Korean semiconductor specialists.

The Samsung Welfare Basis acknowledged Kim’s affect when it
awarded him its prestigious Ho-Am Prize in 1993 for “constructing a stable basis for Korea’s semiconductor {industry}.” Since then, he has been revered within the South Korean media because the {industry}’s “godfather.” But even right this moment, Kim stays largely unknown outdoors of South Korea’s chip neighborhood. Who, then, is that this inconspicuous semiconductor “Mafia” boss?

A Begin in Digicam Chips

Kim Choong-Ki was born in Seoul in 1942, when Korea was a colony of the Japanese Empire. His mom taught elementary college; his father, Kim Byung-Woon, was a textile engineer for
Kyungbang, Korea’s iconic producer of yarns and materials. The elder Kim had helped construct the corporate’s first spinning manufacturing facility, and his engineering savvy and consequent renown impressed his son. “He made a every day tour of the manufacturing facility,” the youthful Kim recollects. “He instructed me that he might detect which machines have been in bother and why, simply by listening to them.” Such classes planted the seed of an ethos that might drive Kim Choong-Ki’s profession—what he got here to name the “engineer’s thoughts.”

Rising up, Kim Choong-Ki was a mannequin South Korean scholar: bookish, obedient, and silent. Though his household pressed him to hitch his father within the textile {industry}, he as a substitute selected to pursue electrical engineering. He studied at Seoul Nationwide College after which at Columbia College, in New York Metropolis, the place he earned his doctorate beneath
Edward S. Yang, a specialist in transistor idea. Shortly after, in the summertime of 1970, Fairchild Digicam and Instrument employed Kim to work in its analysis and improvement laboratory in Palo Alto, Calif.

Since World Warfare II, Fairchild Digicam had been the world’s main developer of imaging tools, together with radar cameras, radio compasses, and X-ray machines. In 1957, the corporate launched the division Fairchild Semiconductor to manufacture transistors and built-in circuits from silicon, then an modern transfer, as most semiconductor gadgets on the time used germanium. The enterprise spawned dozens of merchandise, together with the primary silicon built-in circuit, thus fueling the rise of Silicon Valley. As a newcomer to Fairchild’s R&D lab, Kim was put to work on one in every of these new sorts of chips: the charge-coupled system.

Simply the 12 months earlier than, in 1969, George E. Smith and Willard Boyle at Bell Laboratories
proposed the thought of the CCD, for which they might later win a Nobel Prize. However it was Kim and his colleagues at Fairchild who realized the primary CCD gadgets that developed into industrial merchandise extensively utilized in digital pictures, radiography, and astronomy. Kim turned so proficient in CCD expertise that different engineers on the firm frequently dropped by his workplace on the finish of the day to select his mind. “Quickly they started to name me Professor CCD,” he remembers.

Amongst different innovations, Kim helped develop a
CCD space picture sensor that tremendously improved low-light detection and the primary two-phase CCD linear picture sensor—which, he reported, assured “the convenience of use and the prime quality of picture replica.” “Fairchild’s—or higher name them Choong-Ki’s—CCDs made attainable the huge purposes in high-resolution cameras,” Columbia’s Yang says. With out these practical gadgets, he provides, “there can be no Nobel Prize for the CCD.”

Kim’s time at Fairchild remodeled him as a lot because it did digicam expertise. His education in South Korea and at Columbia had primarily emphasised e-book studying and idea. However his expertise at Fairchild solidified his perception, first impressed by his father, {that a} true “engineer’s thoughts” requires sensible ability as a lot as theoretical data. Along with performing experiments, he made a behavior of studying inside technical reviews and memos that he discovered on the firm library, a few of which he later dropped at KAIST and used as educating materials.

At Fairchild, Kim additionally realized how one can talk with and lead different engineers. When he began there, he was soft-spoken and introverted, however his mentors at Fairchild inspired him to specific himself confidently and clearly. Later, the transformed Kim would turn out to be the “loudest-speaking” professor at KAIST, in accordance with a number of fellow school members, they usually say his absence made the entire campus appear quiet.

Kim rose shortly inside Fairchild’s hierarchy. However simply 5 years into his tenure, he returned to South Korea. His beloved father had died, and, because the eldest son, he felt a heavy duty to look after his widowed mom. Racial discrimination he skilled at Fairchild had additionally damage his pleasure. Most necessary, nevertheless, he had discovered an excellent place to work again residence.

Then known as KAIS (the “T” was added in 1981), Kim’s new employer was the primary science and expertise college in South Korea and stays one of the vital prestigious. The South Korean authorities had established the institute in 1971 with financing from america Company for Worldwide Growth and had invited
Frederick E. Terman, the legendary dean of Stanford College’s college of engineering and a “father” of Silicon Valley, to attract up the blueprint for its route. Terman careworn that KAIS ought to intention to “fulfill the wants of Korean {industry} and Korean industrial institutions for extremely skilled and modern specialists, quite than so as to add to the world’s retailer of primary data.” It was the proper place for Kim to unfold his newfound philosophy of the “engineer’s thoughts.”

South Korea’s Founding Lab

Kim’s laboratory at KAIS attracted scores of formidable grasp’s and doctoral candidates from nearly the second he arrived within the spring of 1975. The first cause for the lab’s reputation was apparent: South Korean college students have been hungry to study semiconductors. The federal government touted the significance of those gadgets, as did electronics firms like GoldStar and Samsung, which wanted them to fabricate their radios, televisions, microwaves, and watches. However the {industry} had but to mass-produce its personal chips past primary built-in circuits equivalent to CMOS watch chips, largely attributable to an absence of semiconductor specialists. For 20 years, till the mid-Nineteen Nineties, becoming a member of Kim’s lab was basically the one approach for aspiring semiconductor engineers in South Korea to get hands-on coaching; KAIS was the one college within the nation that had ready lecturers and correct services, together with clear rooms for assembling high-quality chips.

However it wasn’t KAIST’s digital monopoly on semiconductor coaching that made Kim a mentor with out peer. He launched a method of educating and of mastering engineering that was new to South Korea. As an example, his conviction that an “engineer’s thoughts” requires equal components idea and utility at first puzzled his college students, who regarded engineering as mainly a scholarly self-discipline. Though they have been proficient in arithmetic and nicely learn, most of them had by no means carried out any severe work in design and development.

Due to this fact, one of many first classes Kim taught his college students was how one can use their arms. Earlier than they launched into their very own tasks, he put them to work cleansing the lab, repairing and upgrading tools, and monitoring down obligatory components. On this approach, they realized how one can clear up issues for themselves and how one can improvise in conditions for which no textbook had ready them. Their view of what it means to be an engineer modified profoundly and completely. Lots of them confess they nonetheless repeat Kim’s dicta to today. For instance: “Don’t select the themes that others have already thrown into the trash can.” And: “Scientists contemplate
why first, however we engineers should suppose how first.” And: “Fallacious choice is best than sluggish choice.”

Kim’s former college students keep in mind him as variety, humorous, nonauthoritarian, meticulous, and hardworking. However additionally they say he was strict and might be sizzling tempered and even terrifying, particularly when he thought they have been being lazy or sloppy. Legend has it that a few of his college students entered the lab through a ladder from the rooftop to bypass Kim’s workplace. Considered one of his largest grievances was when college students did not correctly stability idea and observe. “Make it your self; then we are going to begin a dialogue,” he scolded those that centered an excessive amount of on mental examine. Then again, he mentioned, “Why don’t you utilize one thing malleable throughout the onerous nut in your neck?” as a reproach to those that spent an excessive amount of time constructing issues, implying that they need to additionally use their brains.

Kim influenced not solely his personal college students but in addition numerous others by his openness. He cooperated with and even shared laboratory area with different KAIST professors, and he appreciated to go to different departments and universities to present seminars or just to achieve new concepts and views—habits that was, and nonetheless is, very uncommon in South Korean educational tradition. In his autobiography,
Chin Dae-Je, who developed 16-megabit DRAM at Samsung in 1989 and later served as South Korea’s minister of data and expertise, recounts in search of out Kim’s tutelage when Chin was a graduate scholar at Seoul Nationwide College within the mid-Seventies. “There was an intense spirit of competitors” between SNU and KAIST, recollects Chin, whose alma matter labeled him a “drawback scholar” for finding out with a rival professor.

Kim’s collegiality prolonged past academia to {industry} and authorities . Within the early Nineteen Eighties, throughout a sabbatical, he led semiconductor analysis and improvement on the government-funded
Korea Institute of Electronics Know-how, which developed each 32-kilobit and 64-kilobit ROM beneath his directorship. His standard semiconductor workshops at KAIST impressed GoldStar (LG since 1995), Hyundai Electronics (Hynix since 2001), and Samsung to sponsor their very own coaching packages at KAIST within the Nineteen Nineties. Kim’s shut partnership with these firms additionally helped launch different pioneering mostly-industry-funded initiatives at KAIST, together with the Heart for Excessive-Efficiency Built-in Programs and the Built-in-Circuit Design Training Heart, each directed by Kim’s former scholar Kyung Chong-Min. And the semiconductor {industry}, in flip, benefited from the ever extra extremely skilled workforce rising from Kim’s orbit.

The Evolution of South Korea’s Semiconductor Business

Kim’s lab at KAIST developed in parallel with the expansion of the semiconductor sector in South Korea, which will be divided into three durations. In the course of the first interval, starting within the mid-Sixties, the federal government led the cost by enacting legal guidelines and drawing up plans for {industry} improvement, establishing analysis institutes, and urgent firms and universities to pay extra consideration to semiconductor expertise. Samsung and different electronics firms wouldn’t get severe about manufacturing semiconductor gadgets till the early Nineteen Eighties. So when Kim began his lab, nearly a decade prior, he was coaching engineers to satisfy the {industry}’s
future wants.

His first group of scholars labored totally on the design and fabrication of semiconductors utilizing PMOS, NMOS, and CMOS applied sciences that, whereas not leading edge by world requirements, have been fairly superior for the South Korea of the time. As a result of there have been few {industry} jobs, many alumni of Kim’s lab took positions at authorities analysis institutes, the place they developed state-of-the-art experimental chips. An exception was Lim Hyung-Kyu, one in every of Kim’s first grasp’s candidates, whom Samsung despatched to review at KAIST in 1976. Lim would go on to guide the event of varied reminiscence gadgets at Samsung, most significantly NAND flash reminiscence within the Nineteen Nineties.

The second interval began in 1983, when Samsung declared that it could pursue semiconductors aggressively, beginning with DRAM. The transfer drove rival conglomerates equivalent to Hyundai and GoldStar to do likewise. Because of this, the South Korean chip {industry} quickly expanded. KAIST and different universities offered the mandatory manpower, and the federal government lowered its function. In Kim’s lab, college students started to discover rising applied sciences—together with polysilicon thin-film transistors (for LCD panels), infrared sensors (for navy use), and fast thermal processing (which elevated effectivity and lowered prices of semiconductor manufacturing)—and revealed their ends in prestigious worldwide journals.

KAIST graduates flocked to Samsung, GoldStar/LG, and Hyundai/Hynix. As authorities affect declined, some alums from the primary interval who had labored at authorities analysis institutes additionally took company jobs. On the identical time, increasingly of Kim’s former college students accepted college professorships. After leaving Kim’s lab in 1991, as an example, Cho Byung-Jin spent 4 years growing DRAM and flash reminiscence at Hyundai earlier than turning into a star professor on the Nationwide College of Singapore and later at KAIST. Kyung Chong-Min, Kim’s first doctoral candidate, joined KAIST’s school in 1983; by the point he retired in 2018, Kyung had skilled extra semiconductor specialists than Kim himself.

In the course of the third interval, from 2000 on, {industry} seized the helm of semiconductor improvement. Academia churned out extra specialists in addition to important analysis, with minimal contribution from authorities. Alumni of Kim’s lab continued to guide semiconductor engineering, a few of them rising to turn out to be high-ranking executives. For instance,
Kwon Oh-Hyun, who acquired his grasp’s diploma from KAIST in 1977, served as CEO at Samsung Electronics for a lot of the 2010s, when the corporate dominated the world market in not solely reminiscence but in addition cellphones, TVs, and residential home equipment.

Different alums performed key roles in semiconductor analysis and improvement. Ha Yong-Min at LG Show mastered TFT-LCD and OLED screens for tablets, pocket book computer systems, and cellphones; Park Sung-Kye, generally known as the “treasure of Hynix,” developed a lot of the firm’s reminiscence merchandise. In academia, in the meantime, Kim had turn out to be a mannequin to emulate. Lots of his trainees adopted his strategies and ideas in educating and mentoring their very own college students to turn out to be leaders within the area, guaranteeing a gradual provide of extremely expert semiconductor engineers for generations to come back.

Within the spring of 2007, lower than a 12 months earlier than Kim turned 65—the obligatory retirement age in South Korean academia—KAIST elected him as one in every of its first distinguished professors, thus extending his tenure for all times. Moreover the Ho-Am Prize, he has garnered quite a few different awards over time, together with the Order of Civil Advantage for “excellent meritorious providers…within the curiosity of enhancing residents’ welfare and selling nationwide improvement.” And in 2019, he was named a Individual of Distinguished Service to Science and Know-how, one of many nation’s highest honors.

Legend and Legacy

For younger semiconductor engineers in South Korea right this moment, Kim Choong-Ki is a legend—the nice unsung hero behind their nation’s ascendancy in chip manufacturing. However its dominance on the earth market is now beneath risk. Though South Korea has competed furiously with Taiwan in latest many years, its most formidable challenger sooner or later will possible be China, whose formidable
Made in China 2025 plan prioritizes semiconductor improvement. Since 2000, the nation has been a serious importer of South Korean chips. However China’s latest heavy funding in semiconductors and the provision of extremely educated Chinese language engineers—together with semiconductor specialists skilled in america, Japan, and South Korea—implies that Chinese language semiconductor firms might quickly turn out to be main world opponents.

Compounding the issue, the South Korean authorities has uncared for its function in supporting chip improvement within the twenty first century. Almost 50 years after Kim started educating its first semiconductor engineers, the {industry} once more faces a big workforce scarcity. Consultants estimate that
a number of thousand new engineering specialists are wanted every year, however the nation produces just a few hundred. But regardless of firms’ pleas for extra employees and universities’ requires insurance policies that advance educational schooling and analysis, the federal government has accomplished little.

Towards the tip of his profession, Kim had turn out to be involved with the constraints of the form of “engineer’s thoughts” that had taken root in South Korea. “The financial improvement of Korea was depending on reverse engineering and following superior international locations,” he mentioned in an interview in 1997. That fast-follower method, he added, relied on an academic system that taught college students “how one can learn maps”—to determine a identified product objective and plot a course for attaining it. “And who made the maps? Superior international locations.” He thus concluded, “We now have to alter our instructional coverage and train our college students how to attract maps.”

Kim himself could not have absolutely realized this formidable imaginative and prescient of cultivating a rustic of creative-minded engineers, able to pioneering really groundbreaking applied sciences that may safe his nation’s management on the world stage. However hopefully his successors have taken his recommendation to coronary heart. The way forward for South Korea relies on it.
