摘要:
The present invention relates to plasma cleaning methods for removing surface deposits from a surface, such as the interior of a depositions chamber that is used in fabricating electronic devices. The present invention also provides gas mixtures and activated gas mixtures which provide superior performance in removing deposits from a surface. The methods involve activating a gas mixture comprising a carbon or sulfur source, NF3, and optionally, an oxygen source to form an activated gas, and contacting the activated gas mixture with surface deposits to remove the surface deposits wherein the activated gas mixture acts to passivate the interior surfaces of the apparatus to reduce the rate of surface recombination of gas phase species.

A method of forming patterns in a semiconductor device comprises: forming a conductive film on a substrate; forming an anti-reflective layer on the conductive film; cleaning oxide residues on the anti-reflective layer using a first cleaning solution; cleaning the oxide residues on the anti-reflective layer using a second cleaning solution; forming a photoresist pattern on the anti-reflective layer; and patterning the conductive film using the photoresist pattern.
