    摘要: A method is provided for forming a fluorinated silicate glass layer with HDP-CVD having a lower dielectric constant without compromising the mechanical properties of hardness and compressive stress. A gaseous mixture comprising a silicon-containing gas, an oxygen-containing gas, and a fluorine-containing gas is provided to a process chamber. The ratio of the flow rate of the fluorine-containing gas to the flow rate of the silicon-containing gas is greater than 0.65. A high-density plasma is generated from the gaseous mixture by applying a source RF power having a power density less than 12 W/cm2. A bias is applied to a substrate in the process chamber at a bias power density greater than 0.8 W/cm2 and less than 2.4 W/cm2. The fluorinated silicate glass layer is deposited onto the substrate using the high-density plasma.

    摘要: Methods of processing substrates having metal layers are provided herein. In some embodiments, a method of processing a substrate comprising a metal layer having a patterned mask layer disposed above the metal layer, the method may include etching the metal layer through the patterned mask layer; and removing the patterned mask layer using a first plasma formed from a first process gas comprising oxygen (O2) and a carbohydrate. In some embodiments, a two step method with an additional second process gas comprising chlorine (Cl2) or a sulfur (S) containing gas, may provide an efficient way to remove patterned mask residue.
