SOLUTION: Seeds including an amorphous layer, etc. are regularly formed on a base substrate, a nitride based III-V compound semiconductor is grown with an inclined face composed of a facet face, dislocations are propagated by the growth with the inclined face composed of the facet face retained, the dislocations are accumulated to the seed region, the substrate is removed, and a surface of the semiconductor is planarized. Accordingly, a plurality of second regions each having an average dislocation density higher than that of a first region are regularly arranged in the first region of single-crystal to fabricate a nitride based III-V compound semiconductor substrate composed of single-crystal in which C-axis is reversed in the second region about the first region.

SOLUTION: In a reactor 10 where a first organic precursory material 4 as a host material is film-deposited, a vacuum deposition method is applied. A second organic precursory material 6 as a guest material is vaporized by a vaporizer 80 and is mixed with an inert carrier gas 7 fed from a gas refiner 94, and the mixed vapor 8 is introduced into the reactor 10 through piping 87. A mass flow controller 90 is fitted onto the path of the piping 89. The amount of the second organic precursory material 6 to be introduced into the reactor 10 is controlled by the mass flow controller 90, so that the concentration control in doping is performed. The host material is deposited to a substrate W by a vacuum deposition method capable of performing high speed-high precision film deposition, and the guest material is deposited to the substrate W by an OVPD (Organic Vapor Phase Deposition) method which exhibits excellent concentration controllability. As for the host material, the advantages of the vacuum deposition method can be fully utilized, and, as for the guest material, the advantages of the OVPD method can be fully utilized.

    Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor element having a wide low-defect region on the surface and to provide a method for producing a semiconductor element which can easily reduce surface defects in a layer formation step using a lateral growth technique. SOLUTION: A seed crystal layer 201 is grown on a substrate 100, and a growth inhibition layer 216 is formed on the layer 201. That part of the layer 201 which is exposed through the opening of the layer 201 serves as a seed crystal part 215. GaN:Si is grown on the part 215 as a base to form the second seed crystal part 217a. The growth temperature is 1,000°C at the highest. A high-temperature growth part 217b is grown on the part 217a as a base. The growth temperature is 1,050°C at the lowest. The crystal growth proceeds chiefly in the lateral direction to form a continuous unitary layer. Almost no dislocation or crystal defect exists just above the part 217a, and therefore a wide low-defect region is formed on the surface of a nitride semiconductor layer 217.
