Abstract
A method for making an integrated device that includes a plurality of planar MOSFETs, includes forming a plurality of doped body regions in an upper portion of a silicon carbide substrate composition and a plurality of doped source regions. A first contact region is formed in a first source region and a second contact region is formed in a second source region. The first and second contact regions are separated by a JFET region that is longer in one planar dimension than the other. The first and second contact regions are separated by the longer planar dimension. The JFET region is bounded on at least one side corresponding to the longer planar dimension by a source region and a body region in conductive contact with at least one contact region.
