Gould plans to trim its semiconductor operations.

The downsizing will result in the company taking a write-off of about $150 million in the second quarter of 1985, the Rolling Meadows, Ill.-based firm said. The write-off is being taken to address obsolete assets, plant reductions, inventory valuations, offshore facilities and interests in overseas joint ventures. The company cited continued deterioration in the semiconductor market and resulting losses in its semiconductor operations for the downsizing.
