    摘要: In accordance with the present invention, two types of polymeric dielectric systems useful in construction of a high-temperature electrostatic chuck are disclosed. Further, a high temperature power connection for transmitting power from a supply source to a conductive extension from the electrostatic chuck conductive layer is described. The first polymeric dielectric system provides for the use of polyimide films which do not require an adhesive to adhere to an underlying substrate support platen. The self-adhering polyimide film comprises from one to three layers of polyimide material, wherein at least one outer layer of polyimide material is thermoplastic in nature, for the purpose of adhesion and/or encapsulation. When the film comprises two layers, one of the layers is a non-thermoplastic polyimide having an increased glass transition temperature of about 350.degree. C. or greater. When the film comprises three layers, typically the center layer is the non-thermoplastic polyimide, with the upper and lower layers being a thermoplastic polyimide. The thermoplastic polyimide is placed in contact with a substrate to which it is to bond (such as the surface of a conductive platen used to support a semiconductor workpiece) and heat and pressure are applied to cause the thermoplastic polyimide to flow and bond to the substrate. The second polymeric dielectric system provides for the use of a liquid polyamic acid or modified polyimide precursor which is cured in place against a substrate to provide a polyimide-comprising film adhered to the substrate. Depending on the composition of the polyamic acid or modified polyimide precursor, various degrees of crystallinity can be achieved in the cured, solid polyimide.

    摘要: In an optical system measuring sample characteristics, by reducing the amount of ambient absorbing gas or gases and moisture present in at least a portion of the illumination and detection paths experienced by vacuum ultraviolet (VUV) radiation used in the measurement process, the attenuation of such wavelength components can be reduced. Such reduction can be accomplished by a process without requiring the evacuation of all gases and moisture from the measurement system. In one embodiment, the reduction can be accomplished by displacing at least some of the absorbing gas(es) and moisture present in at least a portion of the measuring paths so as to reduce the attenuation of VUV radiation. In this manner, the sample does not need to be placed in a vacuum, thereby enhancing system throughput.

    摘要: The present invention removes unwanted deposited material from a substrate backside by chemically dissolving the material, while substantially preventing dissolution of the material from the substrate front side. Preferably, the dissolving process is included with a spin-rinse-dry process and uses a greater flow rate of rinsing fluid directed onto the front side compared to the flow rate of dissolving fluid directed onto a substrate backside to protect the substrate front side while the unwanted backside material is removed. The present invention includes the method of dissolving the unwanted material from the backside and edge and the associated apparatus.

    摘要: A wafer heater assembly (8) for a deposition/etch chamber (2) includes a base (32) and a wafer support or chuck (36), having a wafer-chucking surface (76), spaced apart from the base by a circumferential barrier support (38). A heater sub-assembly (54) is mounted to the wafer support. Bolts (48) are used to secure the wafer support to the base with the barrier support therebetween to press the barrier support against an elastomeric O-ring, a metal V-seal or other fluid seal (46) positioned between the base and base end (42) of the barrier support. This eliminates the need to discard the entire heater assembly if the dielectric wafer-chucking surface becomes damaged. The temperature of the fluid seal is about 50.degree.-70.degree. C. lower than the temperature of the wafer-chucking surface when the wafer-chucking surface is about 200.degree.-300.degree. C.
