Abstract:
1. An integrated MOSFET and Schottky diode comprising a silicon die having a planar top surface and a bottom surface, a body portion of one conductivity type extending toward said top surface, a plurality of parallel base strips of another conductivity type extending into said body portion from said top surface; a plurality of source region strips extending into respective ones of said base strips to define invertible channel regions; and a gate structure extending along a same direction as said parallel base strips for each of said invertible channel regions; at least selected ones of said source and base strips having interruption areas to serve as schottky regions along their lengths and oriented transverse to the longitudinal axis thereof and the longitudinal axis of at least one gate structure; said body portion extending to said top surface at said interruption areas; a source contact connected to said source regions and a Schottky contact connected to said body portion at said interruption areas.
