Abstract
A blocking semiconductor layer minimizes penetration of implant species into a semiconductor layer beneath the blocking semiconductor layer. The blocking semiconductor layer may have grains with relatively fine or small grain sizes and/or may have a dopant in a relatively low concentration to minimize penetration of implant species into the semiconductor layer beneath the blocking semiconductor layer.
