    摘要: A semiconductor structure includes a semiconductor substrate; a first well region of a first conductivity type in the semiconductor substrate; a metal-containing layer on the first well region, wherein the metal-containing layer and the first well region form a Schottky barrier; and a first heavily doped region of the first conductivity type in the first well region, wherein the first heavily doped region is horizontally spaced apart from the metal-containing layer.
