PROTECT OF SEMICONDUCTOR DEVICE

摘要

The protector protects from the electrostatic charge formed around the input pad (4) of the semiconductor device. Because the charge collecting region (2) absorbing the charge delays the input signal, a resistance layer (R5) is formed on an input passway region (3) connected to the input pad so that the electrostatic charge is absorbed by the region (2) and the input signal is transmitted through a resistance layers (R3,R5). Then the input delay is improved without decreasing the charge collection.
