Title: Field effect transistor
Inventor: WAGAI AKIRA
IPC: H01L21/338
Filed: 1994-09-14
Abstract: PURPOSE: To prevent a leakage current from flowing into a buffer layer by deciding In composition of the buffer layer to perform lattice matching with a substrate besides by making electronic affinity in the part coming in contact with the the substrate equal to that of the substrate and changing so as to gradually minimize an Al composition in the part coming in contact with a channel layer. CONSTITUTION: An InGaAlAs buffer layer 302, where a composition ratio of Ga and Al is gradually changed so that electronic affinity may be equal to InP in the interface with an InP substrate 301 and a band gap may be sufficiently wider than InGaAs in the interface with an InGaAs channel layer 303, is laminated on the InP substrate 301. Accordingly, the triangle well potential is not formed so that electrodes are hard to build up in the interface between the buffer layer 302 and the substrate 301. Thereby, a leakage current stops to flow to the interface between the buffer layer 302 and the substrate 301 so as to heighten an effect of carrier confinement.
