Title: Semiconductor device
Inventor: OCHI MASANORI
IPC: H01L29/778
Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To suppress lowering of transconductance upon occurrence of parallel conduction by employing an electron donating layer having superlattice structure and doping a second semiconductor layer having high electron affinity selectively with an n-type dopant. SOLUTION: A buffer layer 12, a channel layer 13, a spacer layer 14, an electron supply layer 15 and a contact layer 18 are formed sequentially on the major surface of a semi-insulating substrate 11. The electron donating layer 15 has superlattice structure comprising an n-type GaAs layer 15A and an undoped AlGaAs layer 15B. Electrons discharge from the electron donating layer 15 are stored in the potential well of the channel layer 13 and constitute a two-dimensional electron gas. Since excess free electrons exist in the n-type GaAs layer 15A having high mobility in the electron donating layer 15, transconductance is not lowered as compared with the AlGaAs layer 15B even if parallel conduction takes place when the gate bias is shifted positively.
