Latest Patents

One of Andrew J Green's 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. The refractory material is selectively removed to define the gate length and drift regions, followed by annealing to activate the contact regions.
