Abstract
The continuous scaling of MOSFET devices exacerbates short-channel effects (SCEs), such as hot-carrier injection (HCI) and threshold voltage roll-off, thereby compromising electrical performance. While lightly doped drain (LDD) processes are widely adopted in modern CMOS fabrication, conventional methods struggle to maintain performance at advanced technology nodes. This work proposes a novel high-energy LDD technology that overcomes these limitations without introducing additional fabrication complexity. Through rigorous TCAD simulations, the proposed process demonstrates enhanced device stability and improved electrical characteristics, including lower breakdown voltage variation, better threshold voltage control, and improved on/off current ratios. Benchmarked against conventional non-self-aligned (NSA) and self-aligned (SA) LDD processes, this technology offers a viable pathway for next-generation semiconductor scaling.
