Abstract:
A process for depositing a silicon oxide insulating film on a target object in a processing chamber, said process comprising the steps of:introducing a process gas, comprising a gas containing silicon atoms, a gas containing oxygen atoms, a gas containing boron atoms, and a gas containing fluorine atoms into said chamber, wherein the quantity of the boron atoms in the processing gas is 50% or less than the quantity of silicon atoms in the processing gas; and forming plasma from said process gas to deposit a silicon oxide film on said target object, wherein said silicon oxide film is formed by incorporating said boron atoms and said fluorine atoms into the molecular structure thereof; introducing a gas containing, at least one of carbon atoms, nitrogen atoms, and hydrogen atoms to react with the boron atoms and the fluorine atoms constituting a surface of said silicon oxide film, implemented after said step in which said silicon oxide film is formed.
