Title: Formation of nitride oxide film
Inventor: ONISHI TERUTO
IPC: H01L21/3065
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of formating a nitride oxide film not including any impurity with a reduced thermal load on a semiconductor device. SOLUTION: After a substrate 10 to be a semiconductor device is disposed on a lower electrode 2, nitrogen gas is introduced into a vacuum chamber 1 to produce plasma on the substrate. A lower electrode is water cooled so as not to increase the temperature of the substrate. Then, when high frequency power which generates sheathing voltage is applied on the substrate by using characteristics that the sheathing voltage generated between the substrate 10 and the plasma changes owing to a change in power of a high frequency power supply, a nitrogen radical having nitrogen ion or thermal kinetic energy is incident on the surface of the semiconductor substrate whereby nitrogen atoms of high concentration can be introduced into the substrate surface with the control of processing time.  Thereafter, an oxidization processing is performed with mixture gas of oxygen and hydrogen to form a nitrogen oxide film containing a nitrogen element on the substrate surface.
