GATE-ALL-AROUND SEMICONDUCTOR DEVICE WITH TWO GROUP III-V SEMICONDUCTOR NANOWIRES

摘要

A gate-all-around semiconductor device and a method for manufacturing a gate-all-around (GAA) semiconductor device are disclosed. The method comprises providing on a semiconductor substrate (100) in between STI regions (101) at least one suspended nanostructure (105) anchored by a source (121) and a drain region (122), the suspended nanostructure comprising a crystalline semiconductor material which is different from the semiconductor substrate. A gate stack (117) is provided around the at least one suspended nanostructure.
