Embodiments of the invention generally provide a slit valve door seal. In one embodiment, a slit valve door seal includes a ring-shaped base having a center axis and at least one finger extending from the base. The finger is oriented substantially parallel to the center axis, wherein the base and the finger define a single, one-piece seal member. The seal is particularly suitable for using in sealing substrate access passages formed in load lock chambers.

Embodiments of an apparatus for sealing a substrate transfer passage in a chamber are provided. In on embodiment, an apparatus for sealing a substrate transfer passage in a chamber includes an elongated door member having a convex sealing face and a backside. In another embodiment, a chamber having an apparatus for sealing a substrate transfer passage is provided that includes a chamber body having an interior volume, at least one substrate access defined through the chamber body configured to allow passage of a large area substrate therethrough, and a door member having a convex sealing face moveable between a first position that covers the substrate transfer port and a second position clear of the substrate transfer port. In yet another embodiment, the chamber body may be a load lock chamber.

A sputter target assembly particularly useful for a large panel plasma sputter reactor having a target assembly sealed both to the main processing chamber and a vacuum pumped chamber housing a moving magnetron. The target assembly to which target tiles are bonded includes an integral plate with parallel cooling holes drilled parallel to the principal faces. The ends of the holes may be sealed and vertically extending slots arranged in two staggered groups on each side and machined down to respective pairs of cooling holes on opposite sides of the backing plate in pairs. Four manifolds tubes are sealed to the four groups of slots and provide counter-flowing coolant paths.

Embodiments of the invention provide a method of welding sputtering target tiles to form a large sputtering target. Embodiments of a sputtering target assembly with welded sputtering target tiles are also provided. In one embodiment, a method for welding sputtering target tiles in an electron beam welding chamber comprises providing strips or powder of sputtering target material on a pre-determined at least one interfacial line between at least two sputtering target tiles, that are yet to be placed, on a surface of support, placing the at least two sputtering target tiles side by side with edges of the at least two sputtering target tiles abutting and forming at least one interfacial line on top of the strips or powder of sputtering target material, pumping out the gas in the electron beam welding chamber, preheating the at least two sputtering target tiles and the strips or powder of sputtering target material to a pre-heat temperature less than the temperature at which the at least two target tiles begin to melt, undergo a change in physical state, or undergo substantial decomposition, and welding the at least two sputtering target tiles placed side by side into a large sputtering target.

A load lock chamber and method for transferring large area substrates is provided. In one embodiment, a load lock chamber suitable for transferring large area substrates includes a plurality of vertically stacked single substrate transfer chambers. The configuration of vertically stacked single substrate transfer chambers contributes to reduced size and greater throughput as compared to conventional state of the art, dual slot dual substrate designs. Moreover, the increased throughput has been realized at reduced pumping and venting rates, which corresponds to reduced probability of substrate contamination due to particulates and condensation.

In certain aspects, a load lock chamber is provided that includes a body having at least one sealing surface wall including a sealing surface. The sealing surface wall has an opening adjacent the sealing surface adapted to input or output a substrate. The body further includes a plurality of side walls. The load lock chamber also includes a top coupled to the body. The top includes one or more openings that divide the top into a first portion and a second portion. The load lock chamber further includes one or more top sealing members adapted to cover each opening of the top. Each top sealing member absorbs a movement of the first portion of the top relative to the second portion of the top. Numerous other aspects are provided.
