METHOD OF DETERMINING DEPOSITION TEMPERATURE

摘要

A method of determining the deposition temperature, especially inside the reaction chamber of a chemical vapor deposition station. The method includes placing a deposition substrate inside the reaction chamber, forming a layer of metal silicide over the deposition substrate, measuring the silicon/metal atomic ratio and finding the deposition temperature according to a pre-determined temperature versus silicon/metal atomic ratio relationship. The method permits immediate determination as well as real-time monitoring of deposition temperature inside the station.
