ABSTRACT:
A semiconductor device is provided with Zener diodes which are formed by using a polysilicon gate layer(s) so as to be connected to each other in parallel. Parallel-connected rectangular Zener diodes are formed outside an active region or parallel-connected striped Zener diodes are formed inside the active region. The Zener diodes increase the ESD capability of the semiconductor device.
