Latest Patents
One of his latest patents is the "Zig-zag V-MOS transistor structure." This invention discloses a zig-zag V-groove configuration for use in V-MOS transistors. Instead of merely forming parallel rows of V-grooves, this configuration utilizes two different directions for the V-grooves, at least one of which is not the conventional <011> direction. This innovative design can be used with either the ladder or interdigitated configuration for the source contact and gate metals.
Another significant patent is the "Method for manufacture of an interdigitated collector structure." This patent describes a process for manufacturing a bipolar semiconductor by forming a plurality of grooves along the vertical (111) planes in a high resistivity epitaxial silicon layer. This layer is disposed on an N+ (110) oriented substrate. Low resistivity epitaxial silicon of the same conductivity type is then used to fill in the grooves, forming alternate vertical regions of high and low resistivity. A base region is then diffused into the epitaxial layer, and a plurality of emitter regions are diffused into the base region at locations directly above the low resistivity epitaxial regions.
