Abstract
A transistor is disclosed. The transistor includes a gate runner coupled to a gate of the transistor. The transistor also includes a source region and a silicide layer coupling a source metal to the source region. The silicide layer includes a silicide contact area located under the source metal and coupling the source metal to a first portion of the source region under the source metal, and a silicide extension area located under an insulator and providing a lateral coupling from the source metal to a second portion of the source region located under the insulator.
