Plasma doping (PLAD) for advanced memory device manufacturing

Abstract

PLAD (plasma doping) is promising for both evolutionary and revolutionary doping options because of its unique advantages which can overcome or minimize many of the issues of the beam-line (BL) based implants. In this talk, I present developments of PLAD on both planar and non-planar 3D device structures. Comparing with the conventional BL implants, PLAD shows not only a significant production enhancement, but also a significant device performance improvement and 3D structure doping capability, including an 80% contact resistance reduction, more than 25% drive current increase on planar devices, and 23% series resistance reduction, 25% drive current increase on non-planar 3D devices.
