摘要:
A method for manufacturing a heterojunction field effect transistor 1 comprises the steps of: epitaxially growing a drift layer 20a on a support substrate 10; epitaxially growing a current blocking layer 20b which is a p-type semiconductor layer on the drift layer 20a at a temperature equal to or higher than 1000° C. by using hydrogen gas as a carrier gas; and epitaxially growing a contact layer 20c on the current blocking layer 20b by using at least one gas selected from the group consisting of nitrogen gas, argon gas, helium gas, and neon gas as a carrier gas.
