The National Science and Technology Council (NSTC) yesterday said it plans to present new projects within three months that would facilitate the development of power devices used in electric vehicles (EVs) and energy converters to complete the missing piece in the nation’s semiconductor industry.
Aside from the 2-nanometer or 1.4-nanometer semiconductor process technologies, Taiwan also seeks to broaden its semiconductor coverage to include power devices, or power semiconductors, which are made using less advanced technologies, NSTC Minister Wu Cheng-wen (吳誠文) told his first news conference in office yesterday.
Power devices are a key component of energy converters used in smart grids and metal oxide semiconductor field effect transistors for EVs, the NSTC said.

The agency aims to build an extensive smart grid hardware supply chain that covers everything from semiconductor modules to systems, Wu said.
“Taiwan has not made a full effort to develop this segment. This is the missing piece in the nation’s semiconductor industry,” Wu said. “We are aiming to build our own supply of power devices to facilitate the development of smart grids and smart EVs.”
Wu said that his task is to fulfill President William Lai ’s (賴清德) goal of having a “balanced” industrial environment.
As Taiwan has built a robust technology industry, it should leverage the power of technologies such as artificial intelligence to facilitate the development of the traditional sector and “green” energy, among others, he said.
Less advanced 8-inch fabs can be used to produce power devices on mature technology nodes such as 25-nanometer and 65-nanometer technologies, NSTC Deputy Minister Lin Faa-jeng (林法正) said on the sidelines of the news conference.
“There is no need for all companies to develop advanced technologies,” Lin said.
As Taiwan is to usher in an energy environment abound with renewable energy systems, EV charging piles and power storage units, energy converters would be critical to connect solar or other sources of renewable energy to Taiwan Power Co’s (台電) grids, he said.
Power devices are the key component for energy converters, he added.
The NSTC would push for Taiwan to produce the silicon carbide and gallium nitride used to make power devices, Lin said.
Local power device makers are facing difficulties finding the optimal materials and improving their yield rate, resulting in high manufacturing costs, Lin said.
The NSTC plans to offer funding to local universities and colleges to work together with local semiconductor companies to improve power device manufacturing capabilities, Lin said, adding that detailed plans would be unveiled in three months.
In addition to power devices, the NSTC is seeking to collaborate with the Ministry of Economic Affairs to build “science parks” overseas with the assistance of friendly allies, helping smaller businesses to expand their manufacturing footprints globally, Wu said.
That would help mitigate a talent shortage and tight supply of power, he said.
Asked about Taiwan Semiconductor Manufacturing Co’s (TSMC, 台積電) plan to make advanced 2-nanometer chips in the US, Wu said the chip giant has promised to maintain a research-and-development center and its most advanced technologies at home.
TSMC now operates a 2-nanometer R&D center in Hsinchu and plans to ramp up production of 2-nanomter chips there as well as other sites in Taiwan, Wu said.
He said he believes TSMC has the ability to safeguard its corporate secrets and technological know-how.
Nvidia Corp’s demand for advanced packaging from Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) remains strong though the kind of technology it needs is changing, Nvidia CEO Jensen Huang (黃仁勳) said yesterday, after he was asked whether the company was cutting orders. Nvidia’s most advanced artificial intelligence (AI) chip, Blackwell, consists of multiple chips glued together using a complex chip-on-wafer-on-substrate (CoWoS) advanced packaging technology offered by TSMC, Nvidia’s main contract chipmaker. “As we move into Blackwell, we will use largely CoWoS-L. Of course, we’re still manufacturing Hopper, and Hopper will use CowoS-S. We will also transition the CoWoS-S capacity to CoWos-L,” Huang said
Nvidia Corp CEO Jensen Huang (黃仁勳) is expected to miss the inauguration of US president-elect Donald Trump on Monday, bucking a trend among high-profile US technology leaders. Huang is visiting East Asia this week, as he typically does around the time of the Lunar New Year, a person familiar with the situation said. He has never previously attended a US presidential inauguration, said the person, who asked not to be identified, because the plans have not been announced. That makes Nvidia an exception among the most valuable technology companies, most of which are sending cofounders or CEOs to the event. That includes
TARIFF TRADE-OFF: Machinery exports to China dropped after Beijing ended its tariff reductions in June, while potential new tariffs fueled ‘front-loaded’ orders to the US The nation’s machinery exports to the US amounted to US$7.19 billion last year, surpassing the US$6.86 billion to China to become the largest export destination for the local machinery industry, the Taiwan Association of Machinery Industry (TAMI, 台灣機械公會) said in a report on Jan. 10. It came as some manufacturers brought forward or “front-loaded” US-bound shipments as required by customers ahead of potential tariffs imposed by the new US administration, the association said. During his campaign, US president-elect Donald Trump threatened tariffs of as high as 60 percent on Chinese goods and 10 percent to 20 percent on imports from other countries.
INDUSTRY LEADER: TSMC aims to continue outperforming the industry’s growth and makes 2025 another strong growth year, chairman and CEO C.C. Wei says Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), a major chip supplier to Nvidia Corp and Apple Inc, yesterday said it aims to grow revenue by about 25 percent this year, driven by robust demand for artificial intelligence (AI) chips. That means TSMC would continue to outpace the foundry industry’s 10 percent annual growth this year based on the chipmaker’s estimate. The chipmaker expects revenue from AI-related chips to double this year, extending a three-fold increase last year. The growth would quicken over the next five years at a compound annual growth rate of 45 percent, fueled by strong demand for the high-performance computing
