Title:
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/143304
Kind Code:
A1
Abstract:
The embodiments of the present invention disclose a semiconductor device and a manufacturing method therefor. A semiconductor device comprises an active region and a passive region; the semiconductor device further comprises: a source electrode, a gate electrode and a drain electrode which are located on one side of a substrate, the gate electrode being located between the source electrode and the drain electrode; the gate electrode comprises a first end portion and a middle portion, the middle portion, the source electrode and the drain electrode all being located in the active region, and the first end portion being located in the passive region; the first end portion comprises a first sub-end portion and a second sub-end portion; in a first direction, the extending width of the first sub-end portion is greater than the extending width of the middle portion, and the extending width of the second sub-end portion is greater than the extending width of the first sub-end portion; and the first direction is parallel to a direction of the source electrode pointing to the drain electrode. By increasing the extending width of an end portion of a gate electrode, a contact area between a metal of the end portion of the gate electrode and a substrate is increased, thereby improving the device packaging efficiency, ensuring the stability of the structure and the performance of the gate electrode, further improving the operating stability and reliability of a semiconductor device.
