Semiconductor device

摘要

A semiconductor device is disclosed, which includes first and second power supply pads supplied with first and second power voltages, respectively, a first protection circuit coupled between the first and second power supply pads, and an internal circuit including a first power line and a plurality of transistors electrically coupled to the first power line. The first power line includes first and second portions, and the first portion is electrically connected to the first power supply pad. The device further includes a second protection circuit coupled between the second portion of the first power line and the second power supply pad.

主权项

1. A semiconductor device comprising:
a power supply pad; a prescribed circuit including a power supply interconnect; a first interconnect interconnecting said power supply pad and said power supply interconnect; a second interconnect being set to a prescribed potential; a first electrostatic protective element providing a current path from said first interconnect to said second interconnect when potential on said first interconnect reaches a first threshold value; and a second electrostatic protective element disposed between said power supply interconnect and said second interconnect, said second electrostatic protective element providing a current path from said power supply interconnect to said second interconnect when the potential on said first interconnect reaches a second threshold value.
