Abstract:
Provided is an epitaxial substrate for semiconductor elements which suppresses leakage current and has high breakdown voltage. An epitaxial substrate for semiconductor elements includes: a semi-insulating free-standing substrate formed of GaN being doped with Zn; a buffer layer formed of group 13 nitride to be adjacent to the free-standing substrate; a channel layer formed of group 13 nitride to be adjacent to the buffer layer; and a barrier layer formed of group 13 nitride on an opposite side of the buffer layer with the channel layer therebetween, wherein part of a first region consisting of the free-standing substrate and the buffer layer is a second region containing Si at a concentration of 1×10 17  cm −3  or more, and a minimum value of a concentration of Zn in the second region is 1×10 17  cm −3 .

Claim (Index 7):
The semiconductor element according to  claim 5 , wherein\n said buffer layer is formed of GaN, said channel layer is formed of GaN, and said barrier layer is formed of AlGaN.
