Title: Semiconductor device
Inventor: HARADA NAOKI
IPC: H01L27/082
Filed: 1985-12-05
Abstract: PURPOSE:To facilitate the formation of a complementary type circuit excellent in characteristics and reliability by a method wherein a carrier supply layer of one conductivity type with an impurity selectively introduced thereinto is formed on the lower side of a channel layer and another carrier supply layer of the opposite conductivity type is selectively provided on the upper side of the channel layer. CONSTITUTION:A non-doped Al0.3Ga0.7As layer 3 is formed on a semi-insulating GaAs layer 1 with a non-doped GaAs buffer layer 2 placed between. A P-type region 4 is selectively formed at a location in the layer 3 planned for a P- channel element. Next, a non-doped GaAs layer 5 and doped N-type Al0.3Ga0.7As layer 6 are grown one upon the other, in that order. Two-dimensional hole gas 5h is generated in a P-type region 4 in the vicinity of a heterojunction between the layers 5 and 3 and a two-dimensional electron gas 5e is generated in the vicinity of a heterojunction between the layers 5 and 6. Next, removal is accomplished, after which a layer 6 planned for an N-channel element is retained. Etching is performed for the establishment of isolation between elements and then electrodes are built in the prescribed order.
