Abstract:
An isolation structure for active devices is provided. In some embodiments, the isolation structure is used in a transistor. The transistore includes a substrate having a first doping type. The transistor also includes a channel layer positioned over the substrate and comprising a first section and a second section. The transistor further includes an active layer positioned over the channel layer. The isolation structure includes a horizontal segment, a first vertical segment, and a second vertical segment. The horizontal segment is arranged below the second section of the channel layer and continuously extends between the first vertical segment and the second vertical segment. The isolation structure has a second doping type that is different than the first doping type.

Claim (Index 18):
A method of integrated chip fabrication, comprising:\n forming a horizontally extending isolation structure segment having a first doping type within a first region of a substrate having a semiconductor material with a second doping type; forming an epitaxial layer of the semiconductor material onto the substrate; forming two or more III-V semiconductor materials on the epitaxial layer, wherein the two or more III-V semiconductor materials define a heterojunction; forming a conductive path that vertically extends through the two or more III-V semiconductor materials and the epitaxial layer to electrically contact the horizontally extending isolation structure segment; and forming source contacts, drain contacts, and gate structures to define a first device within the first region and a second device within a second region of the substrate.
