"Today's microchips are marvels of nanoscale engineering. A modern microprocessor contains hundreds of millions of transistors packed onto a thumbnail-size piece of silicon. However, our customers are hard at work on designs that will make today’s chips seem crude by comparison.
The semiconducting channel at the heart of each transistor is created, or activated, by quickly heating up the wafer to a set high temperature and cooling it down again, selectively turning the top few atomic layers from an insulator to a semiconductor.
This critical process is called rapid thermal processing, or RTP. Differences of just a few degrees Celsius will change the channel depth enough to affect the whole chip. The effect is small, but at the leading edge, small effects make a major difference.
Applied Materials' Shankar Muthukrishnan discusses the role of RTP in manufacturing microchips and the progression of the technology from the simple furnaces of the 1970s all the way to the state of the art - the Applied Vantage Vulcan RTP system - that was unveiled today."
