    摘要: The invention generally relates to a plasma enhanced chemical vapor deposition chamber for depositing amorphous or microcrystalline silicon on a glass substrate to fabricate solar voltaic cells. The chamber includes a backing plate having at least one fluid receiving conduit to receive cooling fluid to remove heat generated within the chamber by the plasma, thereby stabilizing and cooling the backing plate to assure the uniformity of deposition of materials on the surface of the substrate.

    摘要: Abnormal conditions within an RF-powered plasma process chamber are detected by detecting whether the frequency of a variable-frequency RF power supply moves outside established lower and upper limits. In a first aspect, a first pair of lower and upper limits are established as a function of the frequency of the power supply sampled after a new process step begins or after a sample control signal changes state. In a second aspect, a second pair of lower and upper limits are not adapted to the frequency of the power supply. Both aspects preferably are used together to detect different occurrences of abnormal conditions.

    摘要: Malfunction of a component within an RF-powered plasma chamber is detected by observing an operating condition of the plasma chamber and detecting when the operating condition deviates from a previously observed range bounded by lower and upper limits. The lower and upper limits are determined by observing the minimum and maximum values of that operating condition during the processing of workpieces throughout one or more plasma chamber cleaning cycles immediately preceding the most recent cleaning of the plasma chamber.

    摘要: A method for preventing particle contamination within a processing chamber is disclosed. Preheating the substrate within the processing chamber may cause a thermophoresis effect so that particles within the chamber that are not adhered to a surface may not come to rest on the substrate. One method to increase the substrate temperature is to plasma load the substrate. Plasma loading comprises providing an inert gas plasma to the substrate to heat the substrate. Another method to increase the substrate temperature is high pressure loading the substrate. High pressure loading comprises heating the substrate while increasing the chamber pressure to between about 1 Torr and about 10 Torr. By rapidly increasing the substrate temperature within the processing chamber prior to substrate processing, particle contamination is less likely to occur.
