Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/074737
Kind Code:
A1
Abstract:
According to the present invention, an amplifier is formed in a wiring layer. A semiconductor device according to the present invention comprises a second layer on a first layer, with a metal oxide being interposed therebetween. The first layer comprises a first transistor that has a first semiconductor layer containing silicon. The second layer comprises an impedance matching circuit; and the impedance matching circuit comprises a second transistor that has a second semiconductor layer containing gallium. The first transistor forms a first coupling capacitance with the metal oxide; and the impedance matching circuit forms a second coupling capacitance with the metal oxide. The impedance matching circuit is electrically connected to the metal oxide via the second coupling capacitance. The metal oxide suppresses the influence of a first irradiation noise discharged from the impedance matching circuit on the operation of the first transistor.
