Abstract

According to one embodiment (100), a method of manufacturing a semiconductor device may include forming diffusion regions in a substrate with a gate, first spacer, and second spacer as a diffusion mask (102). A second spacer may then be removed (104) prior to the formation of an interlayer dielectric. An interlayer dielectric may then be formed (106) over a gate structure and first spacer. A contact hole may then be etched through the interlayer dielectric that is self-aligned with the gate (108).
