Former Nanya Technology Corp (南亞科技) president Charles Kau (高啟全) has teamed up with Taiwanese semiconductor equipment maker Scientech Corp (辛耘) to invest in LVG Semiconductor (Huangshi) Co Ltd (祿億半導體) in China to provide wafer reclamation services there.
In a rare appearance in Taipei yesterday, Kau confirmed a report by the Chinese-language Liberty Times (the Taipei Times’ sister newspaper) that he is back after leaving China’s Tsinghua Unigroup Ltd (清華紫光) on Wednesday last week.
During the five-year period with the Chinese group, Kau helped Yangtze Memory Technology Corp (長江存儲), a memory manufacturing arm of Tsinghua Unigroup, develop and produce China’s first 3D NAND flash memory chips.

LVG Semiconductor was founded in Huangshi City, Hubei Province, last year with an initial capital of US$29 million, the Liberty Times reported. The company has not formally started operations yet.
“Market demand is very strong in China, but there is a lack of reclaimed wafer suppliers there,” Kau said.
It is more cost-effective to provide reclaimed wafers from Chinese factories rather than importing them from Taiwan, as the logistics would add US$6 to the overall cost of every reclaimed wafer, he said.
LVG Semiconductor is building its first plant in Huangshi, which is to start operating in the second half of next year, he said.
It would recycle used 12-inch wafers by separating precious metal wires and chemicals to ensure they are not contaminated.
Kau denied that Chinese and foreign funds are involved in LVG Semiconductor.
The company’s shareholders and board directors are all from Taiwan, he said, adding that neither the Chinese government nor global investors have injected capital into the firm.
Kau said he is only an investor in LVG Semiconductor and holds a seat on the company’s board.
Scientech would be in charge of the new company’s operations, he said.
Kau added that he is scouting for other investment targets.
Scientech is a supplier of reclaimed wafers and semiconductor equipment with annual revenue of NT$3.95 billion (US$136.4 million) last year.
China has claimed a breakthrough in developing homegrown chipmaking equipment, an important step in overcoming US sanctions designed to thwart Beijing’s semiconductor goals. State-linked organizations are advised to use a new laser-based immersion lithography machine with a resolution of 65 nanometers or better, the Chinese Ministry of Industry and Information Technology (MIIT) said in an announcement this month. Although the note does not specify the supplier, the spec marks a significant step up from the previous most advanced indigenous equipment — developed by Shanghai Micro Electronics Equipment Group Co (SMEE, 上海微電子) — which stood at about 90 nanometers. MIIT’s claimed advances last
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has appointed Rose Castanares, executive vice president of TSMC Arizona, as president of the subsidiary, which is responsible for carrying out massive investments by the Taiwanese tech giant in the US state, the company said in a statement yesterday. Castanares will succeed Brian Harrison as president of the Arizona subsidiary on Oct. 1 after the incumbent president steps down from the position with a transfer to the Arizona CEO office to serve as an advisor to TSMC Arizona’s chairman, the statement said. According to TSMC, Harrison is scheduled to retire on Dec. 31. Castanares joined TSMC in
EUROPE ON HOLD: Among a flurry of announcements, Intel said it would postpone new factories in Germany and Poland, but remains committed to its US expansion Intel Corp chief executive officer Pat Gelsinger has landed Amazon.com Inc’s Amazon Web Services (AWS) as a customer for the company’s manufacturing business, potentially bringing work to new plants under construction in the US and boosting his efforts to turn around the embattled chipmaker. Intel and AWS are to coinvest in a custom semiconductor for artificial intelligence computing — what is known as a fabric chip — in a “multiyear, multibillion-dollar framework,” Intel said in a statement on Monday. The work would rely on Intel’s 18A process, an advanced chipmaking technology. Intel shares rose more than 8 percent in late trading after the
FACTORY SHIFT: While Taiwan produces most of the world’s AI servers, firms are under pressure to move manufacturing amid geopolitical tensions Lenovo Group Ltd (聯想) started building artificial intelligence (AI) servers in India’s south, the latest boon for the rapidly growing country’s push to become a high-tech powerhouse. The company yesterday said it has started making the large, powerful computers in Pondicherry, southeastern India, moving beyond products such as laptops and smartphones. The Chinese company would also build out its facilities in the Bangalore region, including a research lab with a focus on AI. Lenovo’s plans mark another win for Indian Prime Minister Narendra Modi, who tries to attract more technology investment into the country. While India’s tense relationship with China has suffered setbacks
