摘要:
An HTB gas and a disilane gas are introduced into a process chamber (1), and a hafnium silicate film is formed on a silicon substrate (W) by CVD. The film is formed while controlling the substrate temperature by a heater (5) embedded in a susceptor (2) supporting the substrate. The substrate temperature during film formation is controlled not less than the temperature at which HTB is decomposed into hafnium hydroxide and isobutylene and less than the autolysis temperature of the disilane gas, preferably not less than 350° C. and not more than 450° C.

摘要:
A dry cleaning process for removing native oxide at improved efficiency is disclosed. The dry cleaning process minimizes the amount of fluorine atoms absorbed on the surface of a processed substrate. Fluorine radicals are provided to the substrate together with hydrogen radicals. The substrate is processed by the reaction of the fluorine radicals and the hydrogen radicals.
摘要:
A substrate-processing apparatus (100, 40) comprises a radical-forming unit (26) for forming the nitrogen radicals and oxygen radicals through a high-frequency plasma, a processing vessel (21) in which a substrate (W) to be processed is held, and a gas-supplying unit (30) which is connected to the radical-forming unit. The gas-supplying unit (30) controls the mixture ratio between a first raw material gas containing the nitrogen and a second raw material gas containing oxygen, and supplies a mixture gas of a desired mixture ratio to the radical-forming unit. By supplying the nitrogen radicals and oxygen radicals mixed at the controlled mixture ratio to the surface of the substrate, an insulating film having a desired nitrogen concentration is formed on the surface of the substrate.
