    摘要: The present invention relates to a thin film lamination to be used in a micro InSb thin film magnetic sensor which can directly detect a magnetic flux density with high sensitivity and has small power consumption and consumption current, and the InSb thin film magnetic sensor. The InSb thin film magnetic sensor uses an InSb thin film as a magnetic sensor section or a magnetic detecting section. The sensor includes an InSb layer that is an InSb thin film formed on a substrate, and an AlxGayIn1-x-ySb mixed crystal layer (0≦x, y≦1) which shows resistance higher than the InSb layer or insulation, or p-type conduction, and has a band gap larger than that of InSb. The mixed crystal layer is provided between the substrate and the InSb layer, and has a content of Al and Ga atoms (x+y) in the range of 5.0 to 17%.

    摘要: An objective is to provide a semiconductor device capable of utilizing properties of a high-mobility electron transport layer with a thin film stacked structure having large ΔEc, high electron mobility, and simplified element fabrication process even when the substrate material and the electron transport layer greatly differ in lattice constant. The semiconductor device includes: a semiconductor substrate (1); a first barrier layer (2) on the substrate (1); an electron transport layer (3) on the first barrier layer (2); and a second barrier layer (4) on the electron transport layer (3). The first barrier layer (2) has an InxAl1-xAs layer. At least one of the first barrier layer (2) and the second barrier layer (4) has a stacked structure having an AlyGa1-yAszSb1-z layer in contact with the electron transport layer (3) and an InxAl1-xAs layer in contact with the AlyGa1-yAszSb1-z layer. The stacked structure is doped with a donor impurity.
