摘要： A continuous liquid delivery system which includes at least one primary filter and at least one secondary filter for alternatively receiving a liquid such as a CMP polishing slurry. A primary backwash circuit is provided in fluid communication with each primary filter for backwashing of the primary filter. At least one secondary backwash circuit is provided in fluid communication with each secondary filter for backwashing of the secondary filter. As the liquid is distributed through the primary filter or filters, the secondary filter or filters can be backwashed, and vice-versa to facilitate a continuous flow of the liquid from a source to a destination.

摘要： A new and improved, multi-phase pressure control valve for facilitating quick and accurate attainment and stabilization of gas pressure inside a semiconductor fabrication process chamber such as an etch chamber or CVD chamber. In one embodiment, the multi-phase pressure control valve is a butterfly-type valve which includes outer and inner vanes that independently control flow of gases from a process chamber to a vacuum pump. The larger-diameter outer vane stabilizes gas pressures within a large range, whereas the inner vane stabilizes pressure within a smaller range. In another embodiment, the multi-phase pressure control valve is a gate-type valve which may include a pivoting outer vane and an inner vane slidably disposed with respect to the outer vane for exposing a central gas flow opening in the outer vane.

摘要： Uniform spatial distribution of plasma over the face of a semiconductor wafer is achieved using a multi-zone electrode forming part of an electrostatic chuck used to hold the wafer in a processing chamber. The electrode includes a plurality of concentric electrode portions to which differing RF bias voltages may be applied to produce an electric field having a desired spatial distribution. Sensors are used to monitor either the spatial distribution of the plasma or the process effects of the plasma, and the sensed information is fed back to a controller that adjusts the bias voltage on the electrode portions in a manner to maintain the spatial uniformity of the plasma.
