Abstract: Processing chamber shutter blade and robot blade assemblies are constructed to eliminate thermal effects on the placement of elements in processing chambers. Such blade assemblies may contain at least two parts, which may include a positioning member including a low CTE material and a thermal compensating member including a high CTE material. The positioning member includes a coupling point and a reference point on a reference axis separated by a first distance. The thermal compensating member includes a connection point and a controlled point separated by another distance that is less than the first distance. A distance ratio of the first distance to the other distance is substantially equal to a CTE ratio of the high CTE material to the low CTE material, and the positioning member is joined to the thermal compensating member through the coupling point and the connection point.

Abstract: Embodiments of the invention generally relate to a support ring to support a substrate in a process chamber. In one embodiment, the support ring comprises an inner ring, an outer ring connecting to an outer perimeter of the inner ring through a flat portion, an edge lip extending radially inwardly from an inner perimeter of the inner ring to form a supporting ledge to support the substrate, and a substrate support formed on a top surface of the edge lip. The substrate support may include multiple projections extending upwardly and perpendicularly from a top surface of the edge lip, or multiple U-shaped clips securable to an edge portion of the edge lip. The substrate support thermally disconnects the substrate from the edge lip to prevent heat loss through the edge lip, resulting in an improved temperature profile across the substrate with a minimum edge temperature gradient.

Abstract: A one-piece inner shield usable in a plasma sputter reactor and extending from the target to the pedestal with a smooth inner surface and supported by an annular flange in a middle portion of the shield. The shield may be used to support the RF coil used in exciting the plasma. An outer shield includes an outwardly extending flange on its end alignable with the inner shield flange, holes in correspondence to recesses in the inner shield for standoffs for the RF coil, and circumferentially arranged gas flow holes.

A motor is coupled to the hinge assembly to facilitate moving the lid assembly between the first position and the second position.

Abstract: A magnetron scanning and support mechanism in which the magnetron is partially supported from an overhead scanning mechanism through multiple springs coupled to different horizontal locations on the magnetron and partially supported from below at multiple locations on the target, on which it slides or rolls. In one embodiment, the yoke plate is continuous and uniform. In another embodiment, the magnetron's magnetic yoke is divided into two flexible yokes, for example, of complementary serpentine shape and each supporting magnets of respective polarity. In another embodiment, the target and magnetron are divided into respective strips separated by other structure. Each magnetron strip is supported partially from above from a common scanning plate and partially on a respective target strip. A centering mechanism may align the different magnetron strips.

Abstract: The invention relates to physical vapor deposition (PVD) chambers having a rotatable substrate pedestal. Embodiments of the invention facilitate deposition of highly uniform thin films. In further embodiments, one or more sputtering targets are movably disposed above the pedestal. The orientation of the targets relative to the pedestal may be adjusted laterally, vertically or angularly. In one embodiment, the target may be adjusted between angles of about 0 to 45 degreees relative to an axis of pedestal rotation.

Abstract: One aspect of the invention includes an auxiliary magnet ring positioned outside of the chamber wall of a plasma sputter reactor and being disposed at least partially radially outwardly of an RF coil used to inductively generate a plasma, particularly for sputter etching the substrate being sputter deposited. Thereby, a magnetic barrier prevents the plasma from leaking outwardly to the coil and improves the uniformity of sputter etching. The magnetic field also acts as a magnetron when the coil, when made of the same material as the primary target, is being used as a secondary target. Another aspect of the invention includes a one-piece inner shield extending from the target to the pedestal with a smooth inner surface and supported by an annular flange in a middle portion of the shield. The shield may be used to support the RF coil.
