Disclosed are apparatuses and methods for cutting thin film solar cells. The apparatus may include circular knife cutter rollers, each having a knife edge and coupled with a cutter arbor, support rollers, each coupled to a support arbor and having first and second outer surfaces and a circumferential gap between the first and second outer surfaces partially defined by a first side, a second side facing and offset from the first side, a first rounded edge where the first side intersects with the first outer surface, and a second sharp edge where the second side intersects with the second outer surface. The cutter arbor and support arbor are offset, and the knife cutter rollers and support rollers are axially spaced, such that one knife edge is positioned in the gap of each support roller and the web may be fed between the cutter arbor and the support arbor.

A plasma resistant lightpipe is used in a pyrometric temperature measurement system to measure the temperature of a substrate in a reaction chamber. The plasma resistant lightpipe includes two lightpipe elements. The first lightpipe element, which may be a sapphire rod or aluminum nitride rod, is positioned within a backside gas delivery path to the chamber. The first lightpipe element is resistant to etching caused by reactive plasmas or gases used within the chamber, such as fluorine. The second lightpipe, which is a quartz rod, is positioned beneath the first lightpipe element such that the two lightpipe elements are optically coupled. The first lightpipe element may be directly mounted in the base plate or electrostatic chuck of the pedestal assembly or directly mounted in a plug, which is then positioned within the base plate or electrostatic chuck. The first lightpipe element is securely mounted into the base plate, electrostatic chuck, or the plug by shrink and/or interference fitting, by spring pins or set screws. In one embodiment, the interface between the first lightpipe element and the second lightpipe element is set in a plane defined by the top surface of the seal plate. Thus, there is little danger of damaging the lightpipe elements during the removal of the electrostatic chuck and base plate.

A method is provided for teaching a transfer robot used in conjunction with a workpiece processing system including a pedestal assembly, a light sensor having an optical input fixedly coupled to the pedestal assembly, a transfer robot having an end effector, and a processing chamber containing the pedestal assembly and light sensor. The method includes the steps of producing light within the processing chamber, moving the end effector over the optical input such that amount of light reaching the light sensor varies in relation to the position of the end effector, and recording the signal gain as the end effector is moved over the optical input. The method also includes the step of establishing from the recorded signal gain a desired position of the end effector relative to the pedestal assembly.

A sputtering target assembly, including a cylindrical backing tube, a magnet assembly disposed within the backing tube, and a conduit disposed within the backing tube and adapted for transporting coolant. The conduit includes at least one first opening positioned for providing the coolant in a substantially circumferential direction from the conduit toward an inner surface of the backing tube into a gap volume between a front side of the magnet assembly and the inner surface of the backing tube.

A deposition apparatus includes an input spool located in non-vacuum input module, at least one vacuum process module, an accumulator, and an air to vacuum sealing mechanism. The accumulator and the sealing mechanism are configured to continuously provide a web substrate from the input spool at atmosphere into the at least one process module at vacuum without stopping the web substrate.
摘要:
A sputtering target has a cylindrical backing tube having two edges and a sidewall comprising a middle portion located between two end portions. The sputtering material is on the backing tube. The sputtering material does not cover at least one end portion of the backing tube. The sputtering target also has a feature which prevents or reduces at least one of chalcogen buildup and arcing at the at least one end portion of the backing tube not covered by the sputtering material.
