Title: Semiconductor element
Inventor: MATSUMURA KOJI
IPC: H01L29/80
Filed: 1994-11-21
Abstract: PURPOSE: To provide a semiconductor element which can operate at high speeds by forming a first quantum well except for a part corresponding to a second quantum well with such material that has a faster drift velocity of electrons in a high electric field than the one which constitutes the second quantum well. CONSTITUTION: A channel 5 consists of a first quantum well layer 2 and a second quantum well section 3 which is formed at the center of the first quantum well layer 2 and which has a smaller band gap than the first quantum well layer 2. InP which constitutes a first and a second layer 2a, 2b of the first quantum well layer 2 has a large drift velocity of electrons in a high electric field while In0.8 Ga0.2 As which constitutes the second quantum well section 3 has a large drift velocity of electrons in a low electric field. This means that electrons run in the second quantum well section 3 when a small electric field is applied and they run mainly in the first quantum well layer 2 except for a part corresponding the second quantum well section 3 when a large electric field is applied. Therefore, electrons can run in the channel at high speeds.
