Nanoscale p-MOS Thin-Film Transistor With TiN Gate Electrode Fabricated by Low-Temperature Microwave Dopant Activation

Abstract

In this letter, nanoscale p-MOS TFTs with a TiN gate electrode were realized using a novel microwave (MW) dopant-activation technique. We compared both low-temperature MW annealing and rapid thermal annealing. We successfully activated the source/drain region and suppressed the short-channel effects using low-temperature MW annealing. This technique is promising from the viewpoint of realizing high-performance and low-cost upper layer nanoscale transistors required for low-temperature 3-D integrated circuit fabrication.
