摘要:
Methods for reducing the contamination of a gas distribution plate are provided. In one embodiment, a method for processing a substrate includes transferring the substrate into a chamber, performing a treating process on the substrate, and providing a purge gas into the chamber before or after the treating process to pump out a residue gas relative to the treating process from the chamber. The treating process includes distributing a reactant gas into the chamber through a gas distribution plate.

Methods for removing halogen-containing residues from a substrate are provided. By combining the heat-up and plasma abatement steps, the manufacturing throughput can be improved. Further, by appropriately controlling the pressure in the abatement chamber, the removal efficiency can be improved as well.

A deposition/etching/deposition process is provided for filling a gap in a surface of a substrate. A liner is formed over the substrate so that distinctive reaction products are formed when it is exposed to a chemical etchant. The detection of such reaction products thus indicates that the portion of the film deposited during the first etching has been removed to an extent that further exposure to the etchant may remove the liner and expose underlying structures. Accordingly, the etching is stopped upon detection of distinctive reaction products and the next deposition in the deposition/etching/deposition process is begun.

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.

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.
