Advanced Micro Devices has reached agreement in principle to sell its assembly unit in Manila, the Philippines, to Amkor Electronics Inc, subject to Philippine government approval. Advanced Micro says the move is part of its long-range plan to develop new assembly and test operations at a highly-automated facility in Bangkok, Thailand. AMD will sign Amkor to do assembly at the Manila plant for at least three years after the sale. The two companies have had a long-term relationship for subcontract assembly. Amkor plans to retain the 1,500-strong employees with no reduction and no change in employment terms.
