Electrically programmed MOS transistor source/drain series resistance

摘要

High-speed MOS transistors are provided by forming a conductive layer embedded in transistor gate sidewall spacers. The embedded conductive layer is electrically insulated from the gate electrode and the source/drain regions of the transistor. The embedded conductive layer is positioned over the source/drain extensions and causes charge to accumulate in the source/drain extensions lowering the series resistance of the source/drain regions.
