Abstract
A semiconductor device includes: a semiconductor layered structure including a predetermined mesa portion, formed on a semiconductor substrate; a support member formed so as to bury the mesa portion; and an interconnection layer formed on a top surface of the semiconductor layered structure so as to extend over a top surface of the support member. The interconnection layer is in contact with only a top surface of the mesa portion without being in contact with a bottom surface of the mesa portion. The top surface of the support member has a smoothed profile, and the top surface of the mesa portion and the smoothed top surface of the support member are in substantially the same plane.
