Abstract:
A contact structure in an integrated circuit comprising:a semiconductor substrate having a major surface;a trench isolation region lying within a first portion of the semiconductor substrate, the trench isolation region comprising a trench having a trench sidewall;a first field effect transistor having a source/drain electrode lying within a second portion of the semiconductor substrate, the source/drain electrode having a first portion and a second portion, the first portion having a first depth and a first width and the second portion having a second depth and a second width, wherein the first depth is greater than the second depth and the first width is less than the second width, and the first portion of the source/drain electrode abuts the trench sidewall; anda conductive member overlying the trench isolation region, the conductive member having a first portion extending into the trench adjacent to the trench sidewall, wherein the first portion of the conductive member is electrically shorted to the first portion of the source/drain electrode of the first field effect transistor.
