Semiconductor integrated circuit device with noise protecting shield.

摘要

Disclosed is a semiconductor integrated circuit device having semiconductor integrated circuit blocks (1, 2) disposed close to each other. An insulating layer (20) is interposed between each adjacent pair of the semiconductor integrated circuit blocks. An electroconductive shield member (50) is formed between the adjacent semiconductor integrated circuit blocks to limit the capacitive coupling therebetween. The shield member is electrically insulated from the semiconductor integrated circuit blocks and is maintained at a predetermined fixed potential.
