摘要: A method and apparatus for forming an amorphous carbon layer on a substrate is provided. A first portion of the amorphous carbon layer having a high stress level is formed from a hydrocarbon precursor having high dilution ratio, with optional amine precursor included to add stress-elevating nitrogen. A second portion of the amorphous carbon layer having a low stress level is formed on the first portion by reducing the dilution ratio of the hydrocarbon precursor and lowering or eliminating the amine gas. Pressure, temperature, and RF power input may be adjusted instead of, or in addition to, precursor flow rates, and different precursors may be used for different stress levels.

摘要: A method for forming a semiconductor structure includes forming a plurality of features across a surface of a substrate, with at least one space being between two adjacent features. A first dielectric layer is formed on the features and within the at least one space. A portion of the first dielectric layer interacts with a reactant derived from a first precursor and a second precursor to form a first solid product. The first solid product is decomposed to substantially remove the portion of the first dielectric layer. A second dielectric layer is formed to substantially fill the at least one space.

摘要: Embodiments described herein relate to removing material from a substrate. More particularly, the embodiments described herein relate to polishing or planarizing a substrate by a chemical mechanical polishing process. In one embodiment, a method of chemical mechanical polishing (CMP) of a substrate is provided. The method comprises exposing a substrate having a conductive material layer formed thereon to a polishing solution comprising phosphoric acid, one or more chelating agents, one or more corrosion inhibitors, and one or more oxidizers, forming a passivation layer on the conductive material layer, providing relative motion between the substrate and a polishing pad and removing at least a portion of the passivation layer to expose a portion of the underlying conductive material layer, and removing a portion of the exposed conductive material layer.

摘要: A method and apparatus for forming narrow vias in a substrate is provided. A pattern recess is etched into a substrate by conventional lithography. A thin conformal layer is formed over the surface of the substrate, including the sidewalls and bottom of the pattern recess. The thickness of the conformal layer reduces the effective width of the pattern recess. The conformal layer is removed from the bottom of the pattern recess by anisotropic etching to expose the substrate beneath. The substrate is then etched using the conformal layer covering the sidewalls of the pattern recess as a mask. The conformal layer is then removed using a wet etchant.
