Abstract

A compound semiconductor substrate manufacturing method suitable for manufacturing a compound semiconductor element having high electrical characteristics. The compound semiconductor substrate manufacturing method is a method for manufacturing a compound semiconductor substrate having pn junction, including an epitaxial growing process, a selective growing process and other discretionary processes after the epitaxial growing process. The highest temperatures in the selective growing process and other discretionary processes after the epitaxial growing process are lower than that in the epitaxial growing process prior to the selective growing process.
