摘要：
An electrically conductive mask having openings formed is located above a semiconductor substrate and ions are implanted into the surface of the semiconductor substrate through the electrically conductive mask, thereby forming ion implanted layers. For ion implantation under different conditions, a dedicated electrically conductive mask is used with each ion implantation step.
