Abstract:
1. A transistor for the dissipation of electrostatic discharges, comprising: an intermediate structure comprising a substrate having at least one thick field oxide area, and at least one active area including at least one implanted drain region, and at least one implanted source region, the intermediate structure further including at least one transistor gate member spanned between the at least one implanted drain region and the at least one implanted source region on the at least one active area; a first barrier layer planarized down to the at least one transistor gate member and substantially covering the at least one thick field oxide area and the at least one active area, and adjacent the at least one transistor gate member; at least one drain contact plug extending through the first barrier layer, wherein the at least one drain contact plug is in electrical communication with the at least one implanted drain region on the substrate; at least one source contact plug extending through the first barrier layer, wherein the at least one source contact plug is in electrical communication with the at least one implanted source region on the substrate; an individual drain contact land disposed atop the at least one drain contact plug and a portion of the first barrier layer, the individual drain contact land wider than the at least one drain contact plug; an individual source contact land disposed atop the at least one source contact plug and a portion of the first barrier layer, the individual source contact land wider than the at least one source contact plug; a second barrier layer disposed over the first barrier layer, the individual drain contact land, and the individual source contact land; at least one upper source contact extending through the second barrier layer, the at least one upper source contact in electrical communication with the individual source contact land; and at least one upper drain contact extending through the second barrier layer, the at least one upper drain contact in electrical communication with the individual drain contact land.
