Latest Patents
One of his latest patents is titled "Self-aligned gate and drift design for high-critical field strength semiconductor power transistors with ion implantation." This patent presents methods for forming a self-aligned gate (SAG) and self-aligned source (SAD) device for high electric field semiconductors. The process involves depositing a dielectric layer on a high electric field substrate, etching the dielectric layer to create a drift region, and depositing a refractory material on both the substrate and dielectric layer. The refractory material is then etched to establish a gate length. Implant ionization is applied to create high-conductivity and high-critical field strength sources with SAG and SAD features. The device undergoes annealing to activate the contact regions. An alternative method involves depositing a refractory material on a high electric field substrate, etching it to form a channel region, and applying implant ionization to create high-conductivity source and drain contact regions with SAG and SAD features. The refractory material is selectively removed to define the gate length and drift regions, followed by annealing to activate the contact regions.
