Abstract:
An apparatus for manufacturing a semiconductor wafer comprising:chemical vapor deposition equipment for containing the semiconductor wafer; a dielectric material application system for depositing a low dielectric constant material onto the semiconductor wafer within the chemical vapor deposition equipment by non-chemical vapor deposition; a vacuum pump system for removing oxygen from the semiconductor wafer in said chemical vapor deposition equipment; heating means for heating the semiconductor wafer in said chemical vapor deposition equipment at a temperature below the temperature at which said low dielectric material is oxidized into silicon dioxide and at a temperature at which chemical vapor deposition occurs; and means for depositing a cap material selected from the group containing silicon dioxide, silicon oxynitride, and silicon nitride on said low dielectric constant material by chemical vapor deposition whereby said removing heating, depositing said low dielectric constant material, and depositing said cap material steps are performed sequentially without removing the semiconductor wafer from said chemical vapor deposition equipment.
