Abstract:
A system and methods are provided for low temperature, rapid baking to remove impurities from a semiconductor surface prior to in-situ deposition. The system is configured with an upper bank of heat elements perpendicular to the gas flow path, such that when the substrate is heated, the temperature across the substrate can be maintained relatively uniform via zoned heating. Advantageously, a short, low temperature process is suitable for advanced, high density circuits with shallow junctions. Furthermore, throughput is greatly improved by the low temperature bake.

Claim (Index 13):
A system for vapor deposition on a semiconductor substrate, comprising:\n a reaction chamber configured to support a substrate and flow reaction vapors parallel to a major surface of the substrate along a gas flow path; a reducing vapor source connected to the reaction chamber; one or more deposition vapor sources each connected to the reaction chamber; an upper bank of substantially linear heat lamps above the substrate, each lamp of the upper bank being oriented substantially perpendicular to the gas flow path and substantially parallel to the major surface of the substrate; a lower bank of heat lamps below the substrate; and a computer programmed to control the upper and lower banks of heat lamps, reducing vapor flow from the reducing vapor source through the reaction chamber, and deposition vapor flow from the one or more deposition vapor sources through the reaction chamber to (1) provide power to the upper and lower banks of lamps to subject the substrate to a bake while exposed to the reducing vapor flow for less than 45 seconds, and (2) deposit a layer by vapor deposition directly onto the substrate while exposed to the deposition vapor flow after the bake for less than 45 seconds.
