Patent number: 6423642Abstract: A method for processing a semiconductor wafer or similar article includes the step of spinning the wafer and applying a fluid to a first side of the wafer, while it is spinning. The fluid flows radially outwardly in all directions, over the first side of the wafer, via centrifugal force. As the fluid flows off of the circumferential edge of the wafer, it is contained in an annular reservoir, so that the fluid also flows onto an outer annular area of the second side of the wafer. An opening allows fluid to flow out of the reservoir. The opening defines the location of a parting line beyond which the fluid will not travel on the second side of the wafer. An apparatus for processing a semiconductor wafer or similar article includes a reactor having a processing chamber formed by upper and lower rotors. The wafer is supported between the rotors. The rotors are rotated by a spin motor. A processing fluid is introduced onto the top or bottom surface of the wafer, or onto both surfaces, at a central location.Type: GrantFiled: November 10, 1999Date of Patent: July 23, 2002Assignee: Semitool, Inc.Inventors: Steven L. Peace, Gary L. Curtis, Raymon F. Thompson, Brian Aegerter, Curt T. Dundas

Patent number: 6415863Abstract: A hanger for use in joining tubulars includes an inner tubular with a first portion of length with increasing wall thickness and a second portion of length with decreasing wall thickness through the same longitudinal direction. A swedge sized to expand the inner tubular beyond the yield point to engage and expand the outer tubular is to be drawn through the inner tubular. With the variation in wall thickness, the outer tubular is progressively expanded in an increasing manner and then in a decreasing manner. The difference in inelastic expansion operates to insure an appropriate ultimate fit at one or two areas between the overlapping tubulars. The inner tubular may include a nipple affixed to a liner or may include a liner with an outer filler. In one case, the nipple has varying wall thickness while in the other the filler exhibits the varying wall thickness. A segmented swedge includes portions of the part lines between adjacent segments which are circumferential.Type: GrantFiled: March 4, 1999Date of Patent: July 9, 2002Assignee: Bestline Liner System, Inc.Inventors: Leo D.
