Abstract:
1. A method of controlling an active species of one or more electron beams, said method sequentially comprising: positioning a substrate in a processing chamber; flowing the one or more source gases into the processing chamber, wherein the source gas has an ionization threshold energy level and a dissociation threshold energy level; impinging the source gases with one or more electron beams at a first energy level, which is above the ionization threshold energy level of the source gas, to deposit a first layer of a desired thickness primarily on horizontal surfaces of the substrate; maintaining the flow of the one or more source gases into the processing chamber; and impinging the source gases with one or more electron beams at a second energy level, which is below the ionization threshold energy level and above the dissociation threshold energy level of the source gases, to favor depositing a second layer of a desired thickness on the substrate.
