November 4, 2011 — Numerous global semiconductor suppliers maintain assembly and test operations in Thailand. Many of these facilities have been affected by the disaster. IHS iSuppli pulled together a list of those affected, and those that have thus-far escaped damage.
Semiconductor suppliers whose test and assembly operations have been affected include ON Semiconductor, ROHM Semiconductor, Lapis Semiconductor, Hana Semiconductor, Stars Microelectronics, Vigilant Technology, STATS ChipPac and Toshiba.
ON Semiconductor: ON Semiconductor Corporation (Nasdaq:ONNN) believes that its SANYO Semiconductor division’s Thai operations in the Rojana Industrial Park in Ayutthaya, Thailand have been severely damaged by the flood. Another facility in Bang Pa In, previously unaffected, is now flooded. Read details on ONNN’s closings here.
ROHM: Sole facility in Thailand has been closed since Oct. 19. The facility conducts assembly and test for integrated circuits, discrete transistors, diodes, resistors and tantalum capacitors. ROHM is attempting to shift production to other locations.
Lapis: Rojana Industrial Park operation is closed. Lapis is looking to supply product from alternative locations.
Hana Semiconductor, a subcontractor for Microchip, Texas Instruments (TI) and others: Thai facility is currently flooded, and no assessment is possible. TI and Microchip are relocating as much production as possible to other qualified locations.
Stars Microelectronics: Ayutthaya facility has been flooded. A subcontractor for Microchip, Stars is relocating operations to other sites and anticipates that the impact on production of Microchip
