Latest Patents

Among his latest patents, Siergiej has developed a static induction transistor that features source, drain, and gate regions. The design includes channel regions defined between adjacent gates, with a drift region extending from the ends of the channel regions to the drain. The doping concentrations in the channel regions are greater than those in the drift region, enhancing the transistor's performance. Another significant patent is for a silicon carbide static induction transistor structure. This design utilizes a silicon carbide substrate with a layer arrangement that includes multiple spaced gate regions. These regions control current flow from a source region to a drain region, which is vertically spaced by a drift layer. The pitch distance between gate regions is between 1 to 5 microns, and the drift layer thickness is also within this range. Various embodiments of this invention include alternative positioning of source regions and the use of a dual oxide layer covering the gate and source or drain regions.
