Abstract

An apparatus for a chemical vapor deposition in which at least one substrate which has partially an insulating film on the surface thereof is disposed in a pressure reduced reaction chamber, the reaction chamber is provided with a nozzle for feeding a reactive gas into the reaction chamber, and a light source is provided for emitting a light beam to heat the substrate. The combination of substrate heating source using infrared rays and a laminarized jet of reactive gas is utilized for maintaining the selectivity, facilitating the thin film forming reaction, and improving the high reproducibility and controllability.
