Holy Stone
Passive component maker Holy Stone has announced that the tantalum capacitor plant of its Japan-based subsidiary Holy Stone Ploytech Company (HPC) located in the Fukushima prefecture will resume operations on March 22. The plant was temporarily shut down after the March 11 earthquake.
HTC
Taiwan-based smartphone vendor HTC's supply chain has not been influenced by the earthquake in Japan, and March-April shipments are on schedule, according to company CEO Peter Chou speaking at the Taiwan, Technology and Beyond conference in Taipei on March 16.
MediaTek
IC design house MediaTek on March 15 said that the recent earthquake offshore of Japan will not affect the company's operations. MediaTek indicated that its handset chipsets are mostly shipped to white-box manufacturers in China with end-use devices powered by its chipsets targeted at emerging markets. As for brand vendor clients, MediaTek supplies medium-to-low-end solutions to LG Electronics and Motorola, which mainly manufacture in China, Taiwan and Southeast Asia, with end-use devices also aimed at emerging countries. Though some industry observers are concerned about shipments to Sharp, the Japan-based vendor outsources via the ODM model and handsets are made in China and will not be distributed in Japan.
TSMC
Taiwan Semiconductor Manufacturing Company's (TSMC) target of 20% growth in 2011 sales remains unchanged, chairman and CEO Morris Chang said on March 16. TSMC expects no material impact from the recent earthquake in Japan on its 2011 sales. TSMC is unlikely to face possible wafer supply disruptions, because the company has more than four suppliers, Chang indicated. However, Chang pointed out, the company is unsure whether the event will affect its expansion plans for 2012. Deliveries from its equipment suppliers in Japan may be disrupted by stoppages in their production and the damage to Japan's infrastructure.
UMC
United Microelectronics Corporation's (UMC) Japan subsidiary UMCJ, an 8-inch fab, is located in Tateyama City, Chiba Prefecture, where the earthquake on March 11 recorded 5.0 in magnitude. All UMCJ employees were evacuated and nobody was injured. UMCJ's equipment, accounting for 3-5% of UMC's total foundry capacity, was not damaged and is in the process of calibration for resuming operation. Thus, the earthquake has not substantially brought any financial or operational impact on UMC.
