Patent number: 7674360Abstract: A lift mechanism for and a corresponding use of a magnetron in a plasma sputter reactor. A magnetron rotating about the target axis is controllably lifted away from the back of the target to compensate for sputter erosion, thereby maintaining a constant magnetic field and resultant plasma density at the sputtered surface, which is particularly important for stable operation with a small magnetron, for example, one executing circular or planetary motion about the target axis. The lift mechanism can include a lead screw axially fixed to the magnetron support shaft and a lead nut engaged therewith to raise the magnetron as the lead nut is turned. Alternatively, the support shaft is axially fixed to a vertically moving slider. The amount of lift may be controlled according a recipe based on accumulated power applied to the target or by monitoring electrical characteristics of the target.Type: GrantFiled: September 16, 2004Date of Patent: March 9, 2010Assignee: Applied Materials, Inc.Inventors: Ilyoung Richard Hong, Donny Young, Michael Rosenstein, Robert B.

Patent number: 7673735Abstract: In a semiconductor fabrication facility, a conveyor transports substrate carriers. The substrate carriers are unloaded from the conveyor and loaded onto the conveyor without stopping the conveyor. A load and/or unload mechanism lifts the substrate carriers from the conveyor during unloading operations, while matching the horizontal speed of the conveyor. Similarly, during loading operations, the load/unload mechanism lowers a substrate carrier into engagement with the conveyor while matching the horizontal speed of the conveyor. Individual substrates, without carriers, may be similarly loaded and/or unloaded from a conveyor.Type: GrantFiled: August 14, 2007Date of Patent: March 9, 2010Assignee: Applied Materials, Inc.Inventors: Michael Robert Rice, Robert B. Lowrance, Martin R. Elliott, Jeffrey C. Hudgens, Eric A. Englhardt
