AEP can be used either as a first step followed by a mechanical polish or a second step between initial CMP polish and a third step mechanical polish.

Abstract: A substrate is initially positioned in the reaction chamber. One or more gases are introduced into the reaction chamber. A predetermined speed for translating a line of radiation is determined. Continuous wave electromagnetic radiation is then emitted from a continuous wave radiation source. The continuous wave electromagnetic radiation is subsequently focused into a line of radiation extending across the surface of the substrate. The line of radiation is then translated relative to the surface at the constant predetermined speed. The combination of the introduced gas/es and heat generated by the line of radiation causes the gas/es to react and deposit a layer on the surface of the substrate. Undesirable byproducts of the reaction are then flushed from the reaction chamber. This process is repeated until a layer having a predetermined thickness is formed on the surface of the substrate.

Abstract: A method that is sensitive to lattice damage (also called “primary method”) is combined with an additional method that independently measures one of two parameters to which the primary method is sensitive namely dose and energy. In some embodiments, the additional method is sensitive to dose, and in two such embodiments 4PP and SIMS are respectively used to measure dose (independent of energy). In other embodiments, the additional method is sensitive to energy, and in one such embodiment SIMS is used to measure energy (independent of dose). Use of such an additional method resolves an ambiguity in a prior art measurement by the primary method alone. The two methods are used in combination in some embodiments, to determine adjustments needed to match two or more ion implanters to one another or to a reference ion implanter or to a computer model.

A first protective layer of material is deposited on a substrate surface using traditional sputtering or ion deposition sputtering, in combination with sufficiently low substrate bias that a surface onto which the layer is applied is not eroded away or contaminated during deposition of the protective layer. Subsequently, a sculptured second layer of material is applied using ion deposition sputtering at an increased substrate bias, to sculpture a shape from a portion of the first protective layer of material and the second layer of depositing material. The method is particularly applicable to the sculpturing of barrier layers, wetting layers, and conductive layers upon semiconductor feature surfaces.
