Filed: 2001-06-26
Abstract: PURPOSE: A method for fabricating a semiconductor device is provided to decrease an overall average dielectric constant of a damascene interconnection, by forming an etch barrier layer having superior mechanical strength, oxide resistant and etch selectivity as compared to a conventional low dielectric etch barrier layer. CONSTITUTION: Inert gas is supplied to the inside of a chamber(10) in which a substrate(7) is disposed, so that a reaction pressure is controlled. Alkylsilane gas and nitrogen gas are mixed in a gas mixing receptacle and are supplied to the chamber through a shower head(6). A radio frequency(RF) power generator(5) is operated to apply relatively low RF energy to the shower head so that the alkylsilane gas and the nitrogen gas are reacted to deposit a SiCH thin film on the substrate. Relatively high RF energy is applied to the shower head so that the nitrogen gas is analyzed and a nitrogen radical is formed. The nitrogen radical and the alkylsilane gas are reacted to form a SiCHN thin film on the SiCH thin film so that a multilayered etch barrier layer is formed.
