Low temperature chemical vapor deposition and etching apparatus and method

An apparatus and method for the growth and etching of materialswhere a substrate on which a film is being deposited or which isbeing etched is maintained at a lower temperature than a precursorcracking temperature. The apparatus includes a susceptor withseparators, made of an optically transmissive material with lowthermal conductivity, such as quartz, upon which the substrates aremounted. The susceptor is heated to a precursor crackingtemperature while the substrates are maintained at a lowerdeposition temperature by the separators. The substrates are heatedby black body radiation transmitted through the separators to thesubstrates.
