Abstract

A method of forming low stack height transistors having controllable linewidth in an integrated circuit without channeling is disclosed. A disposable hardmask of doped glass is utilized to define the gate and subsequently protect the gate (and the underlying substrate) during ion implantation which forms the source and drains. An anti-reflective coating helps protect against reflective gate notching. A variety of silicided and non-silicided) structures may be formed.
