    摘要: Etching a layer over a substrate is provided. The substrate is placed in a plasma processing chamber. A first gas is provided to an inner zone within the plasma processing chamber. A second gas is provided to the outer zone within the plasma processing chamber, where the outer zone surrounds the inner zone and the first gas is different than the second gas. Plasmas are simultaneously generated from the first gas and second gas. The layer is etched, where the layer is etched by the plasmas from the first gas and second gas.

    摘要: A method for etching features in a silicon layer is provided. A hard mask layer is formed over the silicon layer. A photoresist layer is formed over the hard mask layer. The hard mask layer is opened. The photoresist layer is stripped by providing a stripping gas; forming a plasma with the stripping gas by providing a high frequency RF power and a low frequency RF power, wherein the low frequency RF power has a power less than 50 watts; and stopping the stripping gas when the photoresist layer is stripped. The opening the hard mask layer and the stripping the photoresist layer are performed in a same chamber.

    摘要: The invention is a method of etching an integrated circuit (IC) structure that includes a metal hard mask layer. The etching of the metal hard mask layer is performed by first feeding a gas mixture comprising a fluorine containing gas and oxygen (O2) gas to a reactor. The method then proceeds to generate a plasma that etches the metal hard mask layer. The method can be applied to either performing a via etch or a trench etch. Additionally, the invention teaches the removal of a photoresist layer without affecting the metal hard mask layer.
