    摘要: A solution for cleaning silicon semiconductors or silicon oxides, and methods for cleaning silicon semiconductors or silicon oxides using the solution, is disclosed. The solution includes hydrogen peroxide, ammonium hydroxide, an alkanolamine, and at least one of a tetraalkylammonium hydroxide, an alkanolamide, an amido-betaine, an α,α-dihydroxyphenol, a carboxylic acid, a phosphonic acid, a chelating agent or a surfactant. The weight ratio of ammonium hydroxide to peroxide to water is between about 1:1:5 and 1:1-4:50, the weight ratio of ammonium hydroxide to water is between 1:5 and 1:50, and the molar ratio of component A to ammonium hydroxide is between 1:10 and 1:5000 is disclosed. The solution can achieve the efficiency equivalent to that of the conventional RCA two-step cleaning solution within a shorter time by one step preserving the silicon and silicon oxide substrate integrity and effectively remove contaminants such as organics, particles and metals from the surfaces of silicon semiconductors and silicon oxides without using strong acids such as HCl and sulfuric acid.

    摘要: Methods of etching a carbon-rich layer on organic photoresist overlying an inorganic layer can utilize a process gas including a fluorine-containing gas, an oxygen-containing gas, and a hydrocarbon gas, and one or more optional components to generate a plasma effective to etch the carbon-rich layer with low removal of the inorganic layer. The carbon-rich layer can be removed in the same processing chamber, or alternatively can be removed in a different processing chamber, as used to remove the bulk photoresist.

    摘要: Methods for reducing contamination of semiconductor substrates after processing are provided. The methods include heating the processed substrate to remove absorbed chemical species from the substrate surface by thermal desorption. Thermal desorption can be performed either in-situ or ex-situ. The substrate can be heated by convection, conduction, and/or radiant heating. The substrate can also be heated by treating the surface of the processed substrate with an inert plasma during which treatment ions in the plasma bombard the substrate surface raising the temperature thereof. Thermal desorption can also be performed ex-situ by applying thermal energy to the substrate during transport of the substrate from the processing chamber and/or by transporting the substrate to a transport module (e.g., a load lock) or to a second processing chamber for heating. Thermal desorption during transport can be enhanced by purging an inert gas over the substrate surface.

    摘要: A plasma processing chamber includes a substrate support having a top surface defined to support a substrate in a substantially horizontal orientation within the chamber. The plasma processing chamber also includes a number of telescopic members disposed within the chamber outside a periphery of the substrate support. The number of telescopic members are also disposed in a concentric manner with regard to a center of the top surface of the substrate support. Each of the number of telescopic members is defined to be independently moved in a substantially vertical direction so as to enable adjustment of an open volume above the top surface of the substrate support, and thereby enable adjustment of a plasma condition within the open volume above the top surface of the substrate support.
