摘要： The width of a heavily-doped sinker is substantially reduced by forming the heavily-doped sinker to lie in between a number of closely-spaced trench isolation structures, which have been formed in a semiconductor material. During drive-in, the closely-spaced trench isolation structures significantly limit the lateral diffusion.

摘要： A junction field-effect transistor (JFET) includes a substrate having a first-type semiconductor surface including a topside surface, and a top gate of a second-type formed in the semiconductor surface. A first-type drain and a first-type source are formed on opposing sides of the top gate. A first deep trench isolation region has an inner first trench wall and an outer first trench wall surrounding the top gate, the drain and the source, and extends vertically to a deep trench depth from the topside surface. A second-type sinker formed in semiconductor surface extends laterally outside the outer first trench wall. The sinker extends vertically from the topside surface to a second-type deep portion which is both below the deep trench depth and laterally inside the inner first trench wall to provide a bottom gate.

摘要： An apparatus includes an enhancement mode transistor having multiple Group III-V layers above a substrate and a gate above the Group III-V layers. The gate includes multiple layers of material that form at least a portion of a thyristor. The multiple layers of material may include a first p-type layer of material, an n-type layer of material on the first p-type layer, and a second p-type layer of material on the n-type layer. The multiple layers of material may also include a p-type layer of material, an n-type layer of material on the p-type layer, and a Schottky metal layer on the n-type layer. The enhancement mode transistor may represent a high electron mobility transistor (HEMT) or a heterostructure field effect transistor (HFET).
