Abstract

A via hole having a bottom is formed in a substrate and then a conductor layer is formed at least over a sidewall of the via hole. Thereafter, the substrate is thinned by removing a portion of the substrate opposite to another portion of the substrate in which the via hole is formed such that the conductor layer is exposed.
