Abstract
A semiconductor substrate according to the present invention includes a nitride semiconductor layer, an amorphous semiconductor layerformed on one main surface side of the nitride semiconductor layer, a high-roughness layerwhich is a semiconductor layer formed on the amorphous semiconductor layerand has a surface roughness larger than the amorphous semiconductor layer, and a diamond layerformed on the high-roughness layer. Damage to the nitride semiconductor layer can be reduced in forming the diamond layer on the nitride semiconductor layer and adhesion between the layers can be increased.
