Abstract

The technique of rapid thermal processing (RTP) has evolved from research laboratory efforts to quickly heat small pieces of semiconductor material using pulsed or scanned lasers to high throughput, production RTP equipment capable of rapidly heating eight-inch silicon wafers to greater than 1000 deg C in 10 seconds. Furthermore, the initial application of annealing ion implantation damage has expanded to include silicide formation, oxide reflow, contact formation, hillock control and more recently oxidation and nitridation. Nearly a dozen vendors now produce RTP equipment and the potential user must answer the question — “Which equipment is best for me?” The researcher's principal concerns for RTP equipment are flexibility and control while the production engineer wants unifomity, reproducibility, and a reasonable throughput. Meanwhile, the device designer wants a “safe” process with no contamination or other adverse device degradation effects. This paper will focus on these and other issues associated with the use of rapid thermal processing from a user' perspective including some thoughts on where RTP may be headed in the future.
