AYUTTHAYA, THAILAND -- On Semiconductor will not reopen its semiconductor probe, assembly and test operations in Thailand for an indefinite period, if at all, due to the severity of the flood damage, the company said.

The site houses On's Sanyo Semiconductor division and some of the former Catalyst Semiconductor products acquired in 2008. Production has been suspended since early October.

The bulk of the company’s Thailand operations will be permanently transferred to other On facilities and to some external subcontractors as appropriate.

In a statement, the company said that "given the severity of the flood damage to the production facilities On Semiconductor operates in Thailand, and the excessive cost required to recover and reconstruct these facilities, that it is not financially viable for us to fully re-start our probe, assembly and test operations in Thailand for an indefinite period, if at all. As such, the company is ceasing all production at its Sanyo sites in Ayutthaya, Thailand, and plans to maintain limited production at its Bang Pa In site."
