Semiconductor device adapted to remove noise from a signal

摘要

What is invented is a semiconductor device ( 10 ) comprising a pellet ( 12 ) having a ground electrode ( 18 ), an outside signal terminal ( 15 ) connected to the pellet ( 12 ), so as to receive signal which is likely to include noise. Therein, said outside signal terminal ( 15 ) is surrounded with a ground terminal ( 17 ) connected to said ground electrode ( 18 ) in at least a half periphery.
