Abstract

See full text

A method for forming a semiconductor device having a fin-type channel is provided. The method may include the following operations: forming a first buffer layer over a substrate; forming a first dielectric layer over the first buffer layer; patterning the first dielectric layer over the first buffer layer; forming a barrier layer over the first buffer layer; forming a second dielectric layer over the barrier layer; patterning the second dielectric layer over the barrier layer; forming a channel layer over the barrier layer; and patterning the second dielectric layer, such that at least a portion of the channel layer protrudes to form the fin-type channel.
