Abstract
A power MOS switch (40) is an array of MOS devices that includes alternating drain columns and source columns. Each drain column includes a plurality of separate drain regions (300) that are closely spaced one from another, and each source column includes a continuous narrow elongated source distribution region (302) that extends the length of the column. A plurality of narrow source distribution branch regions (302) are connected to the elongated region and extend transversely from the elongated region at least partially between each separate drain region in each drain column adjacent to the source column. A gate region (303) separates the drain regions in each column from the adjacent source distribution regions.
