Abstract
There is disclosed a semiconductor device which is at least partially provided with an element having one-conductive type layers 7 and 9 being conductive in reverse to an oppsite conductive type semiconductor substrate 1. At the same time when the one-conductive type layers are formed, the one-conductive type layers 7' and 9' are formed in a region in which a signal input/output pad 14 is formed. Additionally, contact holes 11' are made in peripheral positions of the one-conductive type layers 7' and 9' in an interlayer insulating film 10 which is formed on a surface of the semiconductor substrate 1. In a region surrounded by the contact holes 11, on a surface of the interlayer insulating film 10, the signal input/output pad 14 is formed. Simultaneously with formation of the signal input/output pad 14, in a peripheral position of the signal input/output pad 14 formed is a noise shielding electrode 15 which is electrically connected to the contact holes 11.
