  • Micro heating of selective regions
    Patent number: 6514840
    Abstract: A method for selectively heating a substrate without damaging surrounding regions of the substrate. In particular, the invention provides for a method of selectively activating doped regions of a semiconductor device without damaging surrounding doped and activated regions. Specifically, the invention provides a laser anneal which activates locally doped regions, while surrounding doped and activated regions are protected using a reflective mask.
