    摘要: We have a method of improving the deposition rate uniformity of the chemical vapor deposition (CVD) of films when a number of substrates are processed in series, sequentially in a deposition chamber. The method includes the plasma pre-heating of at least one processing volume structure within the processing volume which surrounds the substrate when the substrate is present in the deposition chamber. We also have a device-controlled method which adjusts the deposition time for a few substrates at the beginning of the processing of a number of substrates in series, sequentially in a deposition chamber, so that the deposited film thickness remains essentially constant during processing of the series of substrates. A combination of these methods into a single method provides the best overall results in terms of controlling average film thickness from substrate to substrate.

    摘要: Embodiments of a gas diffuser plate for distributing gas in a processing chamber are provided. The gas distribution plate includes a diffuser plate having an upstream side and a downstream side, and a plurality of gas passages passing between the upstream and downstream sides of the diffuser plate. The gas passages include hollow cathode cavities at the downstream side to enhance plasma ionization. The depths, the diameters, the surface area and density of hollow cathode cavities of the gas passages that extend to the downstream end can be gradually increased from the center to the edge of the diffuser plate to improve the film thickness and property uniformity across the substrate. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can be created by bending the diffuser plate toward downstream side, followed by machining out the convex downstream side. Bending the diffuser plate can be accomplished by a thermal process or a vacuum process. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can also be created computer numerically controlled machining. Diffuser plates with gradually increasing diameters, depths and surface areas of the hollow cathode cavities from the center to the edge of the diffuser plate have been shown to produce improved uniformities of film thickness and film properties.

    摘要: We have discovered that adding H2 to a precursor gas composition including SiH4, NH3, and N2 is effective at improving the wet etch rate and the wet etch rate uniformity across the substrate surface of a-SiNx:H films which are deposited on a substrate by PECVD. Wet etch rate is an indication of film density. Typically, the lower the wet etch rate, the denser the film. The addition of H2 to the SiH4/NH3/N2 precursor gas composition did not significantly increase the variation in deposited film thickness across the surface of the substrate. The a-SiNx:H films described herein are particularly useful as TFT gate dielectrics in the production of flat panel displays. The uniformity of the film across the substrate enables the production of flat panel displays having surface areas of 25,000 cm2 and larger.

    摘要: We have discovered that controlling a combination of PECVD deposition process parameters during deposition of silicon-containing thin film provides improved control over surface standing wave effects. By minimizing surface standing wave effects, the uniformity of film properties (particularly film thickness) across a substrate surface onto which the films have been deposited is improved. The process parameters which have the greatest effect on surface standing wave effects include: the spacing between the upper and lower electrodes in the plasma reactor; the RF frequency of the plasma source; the amount RF power to the plasma source; the process chamber pressure; the relative concentrations of the various components in the precursor gas composition; and the precursor gas overall flow rate relative to the substrate processing volume.

    摘要: A method and apparatus for depositing a material layer onto a substrate is described. The method includes delivering a mixture of precursors for the material layer into a process chamber and depositing the material layer on the substrate at low temperature. The material layer can be used as an encapsulating layer for various display applications which require low temperature deposition process due to thermal instability of underlying materials used. In one aspect, the encapsulating layer includes one or more material layers (multilayer) having one or more barrier layer materials and one or more low-dielectric constant materials. The encapsulating layer thus deposited provides reduced surface roughness, improved water-barrier performance, reduce thermal stress, good step coverage, and can be applied to many substrate types and many substrate sizes. Accordingly, the encapsulating layer thus deposited provides good device lifetime for various display devices, such as OLED devices. In another aspect, a method of depositing an amorphous carbon material on a substrate at low temperature is provided. The amorphous carbon material can be used to reduce thermal stress and prevent the deposited thin film from peeling off the substrate.
