Efficient cleaning and etching of high aspect ratio structures |
| abstract |
A method for treating a substrate includes arranging a substrate in a processing chamber. At least one of a vaporized solvent and a gas mixture including the solvent is supplied to the processing chamber to form a conformal liquid layer of the solvent on exposed surfaces of the substrate. The at least one of the vaporized solvent and the gas mixture is removed from the processing chamber. A reactive gas including a halogen species is supplied to the processing chamber. The conformal liquid layer adsorbs the reactive gas to form a reactive liquid layer that etches the exposed surfaces of the substrate. |
