The secret sauce for Taiwan’s chip superstardom

When 23-year-old Shih Chin-tay boarded a airplane for the United States in the summertime of 1969, he was flying to a unique world.

He grew up in a fishing village surrounded by sugarcane fields. He had attended college in Taiwan’s capital Taipei, then a metropolis of dusty streets and gray condominium buildings the place folks hardly ever owned vehicles.

Now he was off to Princeton University. The US had only a put a person on the Moon and the Boeing 747 within the skies. Its financial system was bigger than these of the Soviet Union, Japan, Germany and France mixed.

“When I landed, I was shocked,” Dr Shih, now 77, says. “I thought to myself: Taiwan is so poor, I must do something to try and help make it better off.”

And he did. Dr Shih and a bunch of younger, formidable engineers reworked an island that exported sugar and t-shirts into an electronics powerhouse.

Today’s Taipei is wealthy and hip. High-speed trains zip passengers alongside the west coast of the island at 350km/h (218mph). Taipei 101 – briefly the tallest constructing on the planet – towers over the town, an emblem of its prosperity.

Much of that’s all the way down to a tiny system no bigger than a fingernail. The silicon semiconductor – wafer-thin and best-known now as a chip – sits on the coronary heart of each expertise we use, from iPhones to airplanes.

Taiwan now makes greater than half the chips that energy our lives. Its greatest producer, Taiwan Semiconductor Manufacturing Company (TSMC), is the ninth-most helpful enterprise on the planet.

That makes Taiwan practically irreplaceable – and susceptible. China, fearing it might be reduce off from probably the most superior chips, is spending billions to steal Taiwan’s crown. Or it might take the island, because it has repeatedly threatened to do.

But Taiwan’s path to chip superstardom won’t be straightforward to duplicate – the island has a secret sauce, honed by way of many years of laborious work by its engineers. Plus, the manufacturing depends on an internet of financial ties that the escalating US-China rivalry is now attempting to undo.

When Dr Shih arrived at Princeton, “the US was just beginning the semiconductor revolution”, he says.

It had simply been a decade since Robert Noyce made the “monolithic integrated circuit”, packing digital parts onto a single wafer of silicon – an early model of the microchip which kickstarted the non-public pc revolution.

For the 2 years after Dr Shih graduated, he designed reminiscence chips at Burroughs Corporation, second then to IBM in computer-making.

At the time, Taiwan was trying to find a brand new nationwide business following an oil disaster that had pummelled its exports. Silicon appeared like a risk – and Dr Shih thought he might assist: “I thought it was time to come home.”

In the late Seventies, he joined Taiwan’s greatest and brightest electrical engineers at a brand new analysis lab – the staid-sounding Industrial Technology Research Institute would play an outsized position in recasting the island’s financial system.

Work started in Hsinchu, a small metropolis south of Taipei – at present it is a world electronics hub, dominated by TSMC’s monumental fabrication crops. These chip factories, every the scale of a number of soccer fields, are among the cleanest locations on earth. The finer manufacturing particulars are a well-guarded secret, and no outdoors cameras are allowed.

The latest manufacturing unit – the practically $20bn fab 18 in southern Taiwan – will quickly begin producing three-nanometre chips destined for next-generation iPhones.

All of that is far past what Dr Shih and his colleagues imagined once they opened an experimental manufacturing unit within the Seventies. They had been hopeful as a result of they’d expertise licensed from a significant US electronics maker – however to everybody’s shock, the manufacturing unit outperformed its mother or father. It’s exhausting to elucidate why and, to today, the exact formulation for Taiwan’s success stays elusive.

Dr Shih’s recollection is extra prosaic: “Output was better than the original RCA plant, with lower costs. So, this gave the government confidence that maybe we really could do something.”

The Taiwanese authorities put up the preliminary capital – first for the United Micro-electronics Corporation, after which in 1987 for what would turn out to be the world’s greatest chip manufacturing unit – TSMC.

To run it, they recruited Morris Chang, a Chinese-American engineer and former government at US electronics big Texas Instruments. It was a stroke of luck or genius, or each – at present the 93-year-old is called the daddy of Taiwan’s semiconductor business.

Back then, he shortly realised that taking up US and Japanese giants at their very own sport was a dropping proposition. Instead TSMC would solely manufacture chips for others, and never design its personal.

This “foundry model”, which was unparalleled in 1987, modified the panorama of the business and paved the best way for Taiwan to turn out to be the pack chief.

And the timing could not have been higher. Silicon Valley’s new crop of start-ups – Apple, AMD, Qualcomm, Nvidia – didn’t have the funds to construct fab crops of their very own. And they’d battle to search out producers for the chips that they could not operate with out.

“They would have to go to leading semi-conductor companies and ask if they had any excess production capacity they could use,” Dr Shih says. “But then TSMC came along.”

Now California’s “fabless” corporations might accomplice with Taiwan’s chip makers, who had no real interest in stealing their designs or competing with them.

“Rule number one at TSMC is don’t compete with your customers,” Dr Shih says.

The world produces greater than a trillion chips a yr. A contemporary automotive has wherever between 1,500 to three,000 chips. The iPhone 12 reportedly had round 1,400 semiconductors. A shortfall in 2022, pushed by hovering demand for electronics throughout the pandemic, hit gross sales of washing machines and BMWs alike.

Taiwan’s extraordinary success – the island ships greater than half of these trillion-plus chips, and practically all the most superior ones – has been pushed by its mastery of quantity. In different phrases, Taiwanese manufacturing is extremely environment friendly.

Making silicon chips is pricey and painstaking. It begins off with a big ingot of ultra-pure silicon grown from a single crystal. Each ingot could take a number of days to develop and will weigh as much as 100kg.

After a diamond cutter slices the slab into skinny wafers, a machine makes use of gentle to etch tiny circuits onto every wafer. A single wafer could comprise a whole lot of microprocessors, and billions of circuits.

What issues ultimately is the yield – the realm of every wafer that’s usable as a chip. In the Seventies US corporations had yields as little as 10% and, at greatest, 50%. By the Eighties the Japanese had been averaging at 60%. TSMC has reportedly surpassed all of them with a yield that hovers round 80%.

Over time Taiwanese producers have managed to cram an increasing number of circuits into mind-bogglingly smaller areas. Using the most recent extreme-ultraviolet gentle lithography machines, TSMC can etch 100 billion circuits on to a single microprocessor, or over 100 million circuits per sq. millimetre.

Why are Taiwanese corporations so good at this? No-one appears to know precisely why.

Dr Shih thinks it is easy: “We had brand new facilities, with the most up-to-date equipment. We recruited the best engineers. Even the machine operators were highly skilled. And then we didn’t just import technology, we absorbed the lessons from our American teachers and applied continuous improvement.”

A younger man who spent a number of years working at considered one of Taiwan’s largest electronics corporations agrees: “I think Taiwan’s companies are bad at making big breakthroughs in technology. But they are very good at taking someone else’s idea and making it better. This can be done by trial and error, continuously tweaking small things.”

This is vital as a result of in a semiconductor fab the machines should be continuously calibrated. Making microchips is engineering. But it is also greater than that. Some have likened it to cooking – like a connoisseur feast. Give two cooks the identical recipe and elements – the higher cook dinner will make the higher dish.

In different phrases, Taiwan has a secret sauce.

But the younger man, who didn’t wish to reveal his title, or that of the corporate, says Taiwanese corporations have one other benefit.

“Compared to software engineers in the US, even at the best companies here, engineers are paid quite badly,” he stated. “But compared to other industries in Taiwan the pay is good. So, if you work for a big electronic company after a few years, you’ll be able to get a mortgage, buy a car. You’ll be able to get married. So, people suck it up.”

He described a six-day week which started every day with a gathering at 07:30 and would often final till 19:00. He would even be known as in on Sundays or holidays if there was an issue on the plant.

“If people weren’t willing to do the job the company would be finished. It’s because people are willing to put up with hardship that these companies succeed.”

In December 2022 TSMC broke floor on a $40bn plant within the US state of Arizona. It was hailed by President Joe Biden as an indication that high-tech manufacturing was returning to American soil.

Since then the headlines have been considerably much less cheery.

They Wouldn’t Listen To Us: Inside Arizona’s Troubled Chip Plant, learn one. Another stated, TSMC Struggles To Recruit Workers While Facing Pushback From Unions.

Chip manufacturing was supposed to begin subsequent yr. Now it has been put again to 2025.

Former TSMC chairman Dr Chang was deeply sceptical from the beginning. Last yr he described increasing chip manufacturing within the US as an “expensive, wasteful exercise in futility” as a result of manufacturing chips within the US could be 50% costlier than in Taiwan. But Taiwan’s chip-making prowess has put it on the centre of the tech struggle between the US and China.

Washington needs to stop Taiwan supplying China with the cutting-edge chips it fears Beijing will use to speed up its weapons packages and advance its synthetic intelligence.

After Russia’s invasion of Ukraine, which strangled Europe’s gasoline provide, US politicians are jittery about Taiwan. They concern that the large focus of high-end chip manufacturing on the island makes the US financial system hostage to a Chinese invasion.

But Taiwanese corporations see little financial benefit in transferring manufacturing off the island. They are doing so reluctantly underneath political strain.

People in Taiwan resent the concept that they need to be blamed for his or her success – and that Taiwan ought to voluntarily weaken what many regard as its “silicon shield”, whereas the remainder of the world vacillates over whether or not the island and its democratic society is price defending from Chinese aggression.

Dr Shih says those that are searching for to forcibly restructure world chip manufacturing misunderstand its success.

“If you look at the history of semiconductors, no one country dominates this industry,” he says. “Taiwan may dominate the manufacturing sector. But there is a very long supply chain and innovation from every part of it contributes to the growth of the industry. “

Much of the world’s uncooked silicon comes from China, though most of it goes to the photo voltaic business. Germany and Japan lead the cost in chemical compounds which might be essential to course of the wafers.

Carl Zeiss, a German optoelectronics firm higher recognized for making eyewear and digicam lenses, produces optical units that go into the lithography machines made by a number one Dutch firm, ASML. The laborious manufacturing works to designs that originate in American corporations or the UK-based Arm.

Dr Shih is uncertain Beijing can recreate this provide chain – from supplies to design to high-end manufacturing – inside China.

“If they want to create a different model then I wish them luck,” he says with a shrug. “Because if you really want innovation, you need everyone to work together from all around the world. It’s not one company or one country.”

He is simply as uncertain about chopping China out because the US has been doing.

“I think that’s probably a major mistake,” he says. “When I look back, I feel lucky to have witnessed the extraordinary growth of Taiwan’s economy and this long period of peace. Now I see conflict in other parts of the world, and I worry it may come to Asia.

“I hope folks respect the dear effort that we made and will not destroy it.”
