摘要： A method for measuring the concentration of the metal solution and reducing agent solution within the electroless plating solution is disclosed. Raman spectroscopy is used to measure the concentration of each solution within the electroless plating solution after they have been mixed together. By measuring the concentration of each solution prior to providing the solution to a plating cell, the concentration of the individual solutions can be adjusted so that the targeted concentration of each solution is achieved. Additionally, each solution can be individually analyzed using Raman spectroscopy prior to mixing with the other solutions. Based upon the Raman spectroscopy measurements of the individual solutions prior to mixing, the individual components that make up each solution can be adjusted prior to mixing so that the targeted component concentration can be achieved.

摘要翻译： 公开了一种用于测量化学镀溶液中的金属溶液和还原剂溶液的浓度的方法。 拉曼光谱法用于测量化学镀溶液混合在一起后每种溶液的浓度。 通过在将溶液提供给电镀池之前测量每种溶液的浓度，可以调节各溶液的浓度，从而实现每种溶液的目标浓度。 此外，每个溶液可以在与其他溶液混合之前使用拉曼光谱单独分析。 基于混合前单个溶液的拉曼光谱测量，可以在混合之前调整组成每种溶液的各个组分，从而可以实现目标组分浓度。

摘要： A composite insulating film including three layers is formed on a substrate having a gap. The first layer partially fills the gap and contains a dielectric material having a low dielectric constant, such as halogen-doped silicate glass. The second layer is formed over the first layer, and contains an undoped dielectric material such as silicon oxide, nitride, or oxynitride. The second layer is more stable and integrable, and less susceptible to moisture absorption and outgassing, than the first layer. The second layer is substantially smaller in thickness than the first layer, and at least substantially fills the gap. The third layer is formed over the second layer, and contains a dielectric material having a low dielectric constant, such as halogen-doped silicate glass. In a specific embodiment, the first layer is formed by plasma-enhanced chemical vapor deposition in which reactive species are generated from a process gas mixture by plasma for sputtering the first layer.

摘要： An improved deposition chamber (2) includes a housing (4) defining a chamber (18) which houses a substrate support (14). A mixture of oxygen and SiF4 is delivered through a set of first nozzles (34) and silane is delivered through a set of second nozzles (34a) into the chamber around the periphery (40) of the substrate support. Silane (or a mixture of silane and SiF4) and oxygen are separately injected into the chamber generally centrally above the substrate from orifices (64, 76). The uniform dispersal of the gases coupled with the use of optimal flow rates for each gas results in uniformly low (under 3.4) dielectric constant across the film.

摘要： The present invention provides a method of depositing an amorphous fluorocarbon film using a high bias power applied to the substrate on which the material is deposited. The invention contemplates flowing a carbon precursor at rate and at a power level so that equal same molar ratios of a carbon source is available to bind the fragmented fluorine in the film thereby improving film quality while also enabling improved gap fill performance. The invention further provides for improved adhesion of the amorphous fluorocarbon film to metal surfaces by first depositing a metal or TiN adhesion layer on the metal surfaces and then stuffing the surface of the deposited adhesion layer with nitrogen. Adhesion is further improved by coating the chamber walls with silicon nitride or silicon oxynitride.
