Patent number: 6572158Abstract: A window securing device (36) for use in a double-hung sash window assembly having upper and lower sash window frames (14,16) installed for relative overlapping vertical sliding movement, said upper sash frame (14) having a recess into the interior of a vertical facial member of the window. The device (36) includes a housing (38) having a front faceplate opening (51) into a cavity (50) therein and a means for retaining the housing (38) in the recess with the faceplate (42) covering the edges of the recess. A pawl (40) mounted in the cavity (50) of the housing (38) is spring biased into an extended position where the lowermost arresting edge protrudes through the opening (51). In effect, the extended pawl (40) blocks the pathway of a top portion of the lower sash (16) for preventing further upward movement thereof.Type: GrantFiled: February 12, 2002Date of Patent: June 3, 2003Assignee: Ashland Products, Inc.Inventors: Matthew Peter Szapucki, Richard J. Kulkaski

Patent number: 6244641Abstract: A wafer transfer arm made from a machineable material for picking up and delivering a semiconductor wafer from one location to another, includes a blade body with a longitudinal channel extending along one surface, and a coverplate adapted to matingly fit into the channel for defining a vacuum conduit therein. The vacuum conduit provides fluid communication between an inlet at one end of the blade body and an outlet at the other end, for suctionally retaining the semiconductor wafer by vacuum pressure or suction.Type: GrantFiled: December 2, 1999Date of Patent: June 12, 2001Assignee: M.E.C. Technology, Inc.Inventors: Matthew Peter Szapucki, Richard Kulkaski, Trevor J. Hadley, Mark Anthony Santorelli

Patent number: 6170432Abstract: A showerhead electrode assembly for a plasma reactor for processing semiconductor wafers includes a gas plate having a plurality of through holes for passage of gas. The top face or side of the gas plate is of smaller diameter than the bottom side or face of the gas plate. An acutely angled peripheral groove is formed between the top face of the gas plate, and the lower portion thereof, with the groove terminating at a band-like ledge with the top face and lower portion. A locking ring is provided by two identical semicircular sections, each of which include in a lower portion of an inside sidewall, respectively, an acutely angled peripheral groove for mating with the groove of the gas plate. A unitary circular support collar is formed with a circular channel in a bottom portion thereof.Type: GrantFiled: January 24, 2000Date of Patent: January 9, 2001Assignee: M.E.C. Technology, Inc.Inventors: Matthew Peter Szapucki, Richard Kulkaski, Trevor J. Hadley, Mark Anthony Santorelli

Patent number: 6050216Abstract: A plasma reactor showerhead electrode assembly for processing semiconductor wafers comprised of a typically silicon disk shaped gas plate having a plurality of gas passage holes therethrough, and a graphite circular split collar assembly including first and second semicircular sections forming a circumferential inner slot when opposing ends of said sections are secured together, the slot mating in a dovetail connection with an outer circumferential groove of said gas plate for retaining the latter between said sections. A conductive gasket may be interposed between the gas plate groove and the mating collar assembly to provide an electrically and thermally conductive seal. The first and second semicircular sections have opposing ends screwed or pinned together for providing easy disassembly thereof for replacement of the gas plate.Type: GrantFiled: August 21, 1998Date of Patent: April 18, 2000Assignee: M.E.C. Technology, Inc.Inventors: Matthew Peter Szapucki, Richard Kulkaski, Trevor J. Hadley, Mark Anthony Santorelli, Robert H. Stoever

Patent number: 5657975Abstract: A clip assembly for retaining a semiconductor wafer on a pedestal during processing of the wafer, and releasing the wafer for removal from the pedestal after processing, includes a pair of tines each having a lower sloping surface for contacting an edge of an associated semiconductor wafer, and a ledge provided immediately above the lower sloping surface inward from a shared leading edge serves to catch debris or particulate material, preventing it from falling onto the surface of the semiconductor wafer. A metal spring, biasing the clip head into contact with the wafer, has an upper portion molded into the electrically non-conductive material of the clip head behind a front face thereof, whereby the spring and clip head form a monolithic assembly.Type: GrantFiled: June 6, 1995Date of Patent: August 19, 1997Inventors: Matthew Peter Szapucki, Richard Kulkaski
