Site Report: Yamanashi Regional Office
Here we will introduce examples of initiatives at one particular plant. This time wereport on the activities of the Yamanashi Plant, comprised of the Fujii area, whichprimarily manufactures products, and the Hosaka area, which primarily conducts
research and development for semiconductor processes.
