The plant is at the Jhunan Science Park (竹南科學園區) in Miaoli County, SAS said in a regulatory filing on Thursday. SAS, which has a 41.94 percent stake in Crystalwise, has its own plants in Jhunan and Yilan County. It has also installed cleanroom equipment, the Liberty Times reported. As the company is seeking to transform, it is researching semiconductor materials and might make additional investments in the new plant, the Chinese-language Commercial Times reported on Friday. SAS’ net profit plunged 54.15 percent to NT$1.16 billion in the first three quarters of this year, compared with NT$2.53 billion in the same period last year.
