摘要:
A circuit structure includes a substrate, a nucleation layer of undoped aluminum nitride, a graded buffer layer comprising aluminum, gallium, nitrogen, one of silicon and oxygen, and a p-type conductivity dopant, a ungraded buffer layer comprising gallium, nitrogen, one of silicon and oxygen, and a p-type conductivity dopant without aluminum, and a bulk layer of undoped gallium nitride over the ungraded buffer layer. The various dopants in the graded buffer layer and the ungraded buffer layer increases resistivity and results in layers having an intrinsically balanced conductivity.

A high electron mobility transistor (HEMT) includes a first III-V compound layer. A second III-V compound layer is disposed on the first III-V compound layer and is different from the first III-V compound layer in composition. A source feature and a drain feature are in contact with the second III-V compound layer. A n-type doped region underlies each source feature and drain feature in the second III-V compound layer. A p-type doped region underlies each n-type doped region in the first III-V compound layer. A gate electrode is disposed over a portion of the second III-V compound layer between the source feature and the drain feature.

Provided is a method of fabricating a semiconductor device. The method includes: receiving a silicon wafer that contains oxygen; forming a zone in the silicon wafer, the zone being substantially depleted of oxygen; causing a nucleation process to take place in the silicon wafer to form oxygen nuclei in a region of the silicon wafer outside the zone; and growing the oxygen nuclei into defects. Also provided is an apparatus that includes a silicon wafer. The silicon wafer includes: a first portion that is substantially free of oxygen, the first portion being disposed near a surface of the silicon wafer; and a second portion that contains oxygen; wherein the second portion is at least partially surrounded by the first portion.
