SELF ALIGNED IMPACT-IONIZATION MOS (I-MOS) DEVICE AND METHODS OF MANUFACTURE

摘要

A method of forming a semiconductor structure, including forming a gate structure on a substrate; performing a first angled implantation on a first side of the gate structure to form a first doped region in the substrate, the first doped region partially extends within a channel of the gate structure and the gate structure blocks the first angled implantation from affecting the substrate on a second side of the gate structure; forming sidewall spacers on sidewalls of the gate; and forming a second doped region in the substrate on the second side of the gate, spaced apart from the channel.
