IPC: H01L21/285
Filed: 1991-09-12
Abstract: PURPOSE:To form a high performance interlayer dielectric film by selecting silicon oxide as the material for interlayer dielectric film and employing TEOS as Si source in the filming while optical energy in the reaction. CONSTITUTION:Light from a light source(low pressure mercury lamp) 9 disposed in a light source chamber 6 transmits through a window 10 and enters into a reaction chamber. The light source 9 is constituted of eleven low pressure mercury lamps arranged in an area of 400cm<2> and has irradiation intensity of about 1mW/cm<2>. The light is condensed to an irradiation area of 100cm<2> in the vicinity of a substrate. TEOS and oxygen as reactive gas and nitrogen as buffer gas are introduced into the reaction chamber from a gas introduction system 7. TEOS is fed in vapor phase by heating a cylinder and piping at 160 deg.C. Reaction chamber is irradiated with light from the low pressure mercury lamp in order to deposit silicon oxide on a substrate 1. This method allows deposition of silicon oxide on the substrate with good step coverage.
