Patent ID: 8859042

Claim:
A method for heating a substrate or a substrate susceptor within a flow vapor deposition reactor system by a heating lamp assembly, comprising: exposing a lower surface of a substrate susceptor to energy emitted from a heating lamp assembly disposed beneath a wafer carrier track, and heating the substrate susceptor to a predetermined temperature, wherein the heating lamp assembly comprises: a first elongate lamp holder and a second elongate lamp holder parallel to the first elongate lamp holder, the first and second elongate lamp holders having a plurality of pairs of spaced apart posts on one side of each of the lamp holders, the first and second lamp holders disposed on an upper surface of a support base within a vertical flow vapor deposition reactor, wherein the first lamp holder and the second lamp holder each have a thickness within a range from about 0.001 inches to about 0.1 inches and the first lamp holder and the second lamp holder are each independently maintained at a temperature within a range from about 275° C. to about 375° C.; a plurality of lamps, each lamp extending from a position in between a pair of posts from the first lamp holder to a position in between a pair of posts of the second lamp holder; and a reflector disposed on the upper surface of the support base, in between the first and second elongate lamp holders and below the lamps, wherein the substrate susceptor is adapted to move along the wafer carrier track while being heated by the heating lamp assembly.
