Abstract
A conductive-insulator-semiconductor (CIS) device with low flicker noise is provided. In some embodiments, the CIS device comprises a semiconductor substrate, a pair of source/drain regions, a selectively-conductive channel, and a gate electrode. The pair of source/drain regions is in the semiconductor substrate, and the source/drain regions are laterally spaced. The selectively-conductive channel is in the semiconductor substrate, and extends laterally in a first direction, from one of the source/drain regions to another one of the source/drain regions. The gate electrode comprises a pair of peripheral segments and a central segment. The peripheral segments extend laterally in parallel in the first direction. The central segment covers the selectively-conductive channel and extends laterally in a second direction transverse to the first direction, from one of the peripheral segments to another one of the peripheral segments. A method for manufacturing the CIS device is also provided.
