Abstract
Disclosed is a semiconductor device, which includes: forming a first channel layer including a Group III-V compound or germanium (Ge) and having a first semiconductor characteristics on a first substrate; forming a second channel layer including a Group III-V compound or germanium (Ge) and having a second semiconductor characteristics different from the first semiconductor characteristics on the first channel layer; forming a bonding layer containing an oxide on a second channel layer; allowing the bonding layer to be bound to the second substrate so that a structure including the bonding layer, the second channel layer, the first channel layer and the first substrate may be stacked on the second substrate; removing the first substrate stacked on the second substrate; and removing the first channel layer from a partial region of the structure stacked on the second substrate.
