Abstract:
A semiconductor device and a method for producing a semiconductor device are disclosed. The semiconductor device includes a first silicon layer; a first dielectric layer, located on the first silicon layer, where the first dielectric layer includes a window, and a bottom horizontal size of the window of the first dielectric layer is not greater than 20 nm; and a III-V semiconductor layer, located on the first dielectric layer and in the window of the first dielectric layer, and connected to the first silicon layer in the window of the first dielectric layer. A III-V semiconductor material of the semiconductor device has no threading dislocations, and therefore has relatively high performance.

Claim (Index 1):
A method for producing a semiconductor device, comprising:\n etching a silicon layer of silicon on insulator (SOI) using a patterned template as a mask, the SOI comprising a silicon substrate, a dielectric layer on the silicon substrate, and the silicon layer on the dielectric layer, and a window of the silicon layer being etched to expose the dielectric layer; etching the dielectric layer using the silicon layer having the window as a template, a window of the dielectric layer being etched to expose the silicon substrate, and the window of the dielectric layer being shaped to limit a size of contact surface exposed over the silicon substrate; and growing a semiconductor material in the window of the dielectric layer to form a buffer layer, the semiconductor material being further grown on the buffer layer to obtain a semiconductor layer, the limited size of the contact surface to reduce threading dislocations of the semiconductor material within the window of the dielectric layer.
