Publication number: 20170294431Abstract: The present disclosure relates to a semiconductor chip having a level shifter with electro-static discharge (ESD) protection circuit and device applied to multiple power supply lines with high and low power input to protect the level shifter from the static ESD stress. More particularly, the present disclosure relates to a feature to protect a semiconductor device in a level shifter from the ESD stress by using ESD stress blocking region adjacent to a gate electrode of the semiconductor device. The ESD stress blocking region increases a gate resistance of the semiconductor device, which results in reducing the ESD stress applied to the semiconductor device.Type: ApplicationFiled: June 19, 2017Publication date: October 12, 2017Applicant: Magnachip Semiconductor, Ltd.Inventors: Kyong Jin HWANG, Hyun Kwang Jeong
