[News] VIS Acquires AUO’s Singapore Plant for Advanced 12-inch Fab on Auto Chip  

According to Economic Daily News, industry insiders said that Vanguard International Semiconductor (VIS) is in talks to acquire land and facilities from AUO’s Singapore plant for its first 12-inch fab. The estimated investment for this project is a substantial US$2 billion. VIS is making a strategic move to specialize in producing advanced chips for the automotive industry.

AUO is scheduled to hold a conference on October 31st, and VIS will follow suit on November 7th. Both companies are currently in a pre-conference quite period and haven’t made any official comments on the recent rumors.

Per reports, AUO has been gradually relocating its equipment from its Singapore plant back to Taiwan. Following a model where AUO sold its L3B fab and related facilities in Hsinchu Science Park, Taiwan, they plan to sell this Singapore plant to VIS. Notably, this Singapore plant is conveniently located just an eight-minute drive away from TSMC’s Singapore plant (SSMC), and the transaction is estimated to be worth over a billion dollars.

The Singapore plant in question was acquired by AUO in 2010, and it specializes in the production of 4.5th generation low-temperature polycrystalline silicon (LTPS) display panels and also has some capacity for AMOLED displays. However, the land use contract for this plant expired during the pandemic. AUO then redirected the plant’s focus towards supporting display production. However, with a decrease in post-pandemic notebook demand, AUO’s strategy in Singapore shifted from manufacturing to establishing itself as a regional service center.

Recent developments show that AUO has begun a significant production line adjustment.  They’re transforming the Longtan Aspire Park in Northern Taiwan into a hub for mass-producing Micro LED technology and integrated automotive display modules. Insiders suggest that AUO’s LTPS production line in the Singapore plant has already started moving to Longtan Aspire Park, where they’re gearing up for Micro LED technology development and eventual mass production.

Regarding AUO’s Singapore plant, the company recently stated that they are conducting a thorough evaluation of the operational efficiency of their various plants worldwide. The production schedule for the Singapore plant extends until early 2024, and they’ll subsequently assess the equipment and assets. The company is in the process of discussing and evaluating the related strategies, and they haven’t made any final decisions yet. AUO’s Singapore plant employs approximately 500 people, and they are committed to following local regulations to safeguard their employees’ rights.

In an earning calls last year, Chairman of VIS, Leuh Fang, revealed that the company already operates five 8-inch fabs. Fab 5 still has the potential for increased wafer production, but due to the challenges of acquiring new 8-inch equipment, establishing a brand-new 12-inch fab in Singapore makes more sense if customer demand necessitates capacity expansion.

This development isn’t entirely surprising, as there’s a precedent for fab transactions between AUO and VIS. In late April 2021, AUO sold its L3B plant in the Hsinchu Science Park, along with its related equipment, to VIS for NT$905 million (pre-tax).
