    摘要: An AlN layer (2), a GaN buffer layer (3), a non-doped AlGaN layer (4a), an n-type AlGaN layer (4b), an n-type GaN layer (5), a non-doped AlN layer (6) and an SiN layer (7) are sequentially formed on an SiC substrate (1). At least three openings are formed in the non-doped AlN layer (6) and the SiN layer (7), and a source electrode (8a), a drain electrode (8b) and a gate electrode (19) are evaporated in these openings.

    摘要: A semiconductor device includes a buffer layer of AlGaAs that contains oxygen with a concentration level in the approximate range of 8.times.10.sup.17 cm.sup.-3 to 6.times.10.sup.19 cm.sup.-3, and carbon with a concentration level in the approximate range of 2.times.10.sup.16 cm.sup.-3 to 2.times.10.sup.17 cm.sup.-3. A lattice constant of the AlGaAs buffer layer is larger than a lattice constant of the GaAs substrate so a lattice misfit of the AlGaAs layer with respect to the GaAs substrate is equal to or varies by no more than 2.times.10.sup.5 from a corresponding lattice misfit between an undoped AlGaAs crystal with respect to the GaAs substrate. Oxygen atoms occupy an interstitial site, creating a deep impurity level that suppresses side gate effect.

    摘要: In a method for growing a III-V group compound semiconductor crystal, as a Si dopant, a compound including a Si atom bonded to an alkyl group and a hydrogen atom is used. Also, a compound including two Si atoms in one molecule thereof, at least one of said Si atoms being bonded to a hydrogen atom, and at least the other of said Si atoms being bonded to an alkyl group can be used. Further, a compound including two Si atoms in one molecule thereof, at least one of said Si atoms being bonded to a hydrogen atom, and at least the other of said Si atoms being bonded to a phenyl group or a compound including a Si atom bonded to an organic amino group can be used. Si can be doped evenly at a high concentration at a low temperature with a safe operation by the invention.
