At least part of the shank intermediate between its ends has an external screw thread having a sharp crest, and can be radially expanded to cause the thread to embed in the workpiece. A bore extends through the head and the entire shank or at least the threaded port of the shank for receiving means for expanding the shank. An end portion of the shank remote from the head may be unthreaded to avoid splitting of the shank during expansion.The method of installing the fastener involves pulling a tapered mandrel along the bore to expand the shank. The mandrel may have a key-forming head of non-circular cross-section whereby the bore of the fastener can be adopted to receive a key of non-circular cross-section for turning the fastener in the workpiece.Type: GrantFiled: October 28, 1986Date of Patent: October 27, 1987Assignee: Advel LimitedInventors: William D. Bradley, Zia R. Alvi, Raymond D. Lacey

Patent number: 4701996Abstract: Edge channel FET structural geometry and processing is disclosed. A plurality of mesa stacked horizontal layers are provided including source and drain semiconductor layers (74, 76) separated by an insulator layer (75) and having exposed edges (78, 80) at a generally vertical side (83) of the mesa. A generally vertical semiconductor layer (84) extends along the side of the mesa over the exposed source and drain layer edges and forms a channel (93). A gate layer (91, 92) on the channel controls depletion region spreading in the channel layer to control conduction therethrough between the source and drain layers. Channel length is extremely small, as low as 0.1 micron. Ohmic contacts (87, 90) to the source and drain layers are defined several microns away from the conducting channel, resulting in considerable reduction in fabrication complexity, as well as improved reliability. Fabrication and alignment of the gate to the active channel layer is simplified.Type: GrantFiled: February 20, 1986Date of Patent: October 27, 1987Inventor: Joseph A. Calviello

Patent number: 4701998Abstract: A method for fabricating a bipolar transistor having a base doping variation of less than 20% is disclosed. A polysilicon base contact bipolar transistor is formed up to the point just prior to the intrinsic base-emitter formation. The intrinsic base-emitter opening is then reactive ion etched through the polysilicon base contact layer down to and into a single crystal silicon body thereunder, whereby the surface of the single crystal silicon is damaged. A silicon dioxide layer is then grown on the exposed and damaged single crystal silicon to convert the damaged silicon surface into a silicon dioxide layer. The silicon dioxide layer is removed by chemical etching to expose undamaged single crystal silicon. A screen silicon dioxide layer 50 to 500 .ANG..+-.10%, e.g., 180 .ANG., is then formed on the thus exposed undamaged single crystal silicon.Type: GrantFiled: December 2, 1985Date of Patent: October 27, 1987Assignee: International Business Machines CorporationInventors: David C. Ahlgren, Robert E. Bendernagel, Russell C. Lange, Martin Revitz

Patent number: 4701999Abstract: A method of making an integrated circuit package comprising an integrated "chip" within an hermetically sealed housing with external electrical leads extending from the chip terminals, and the product formed by such method. The method involves injection molding of a thermoplastic rim on and in sealed relation to a lead frame prior to locating the chip in the central region of the frame and installing fine wire connections from the chip terminals to the lead fingers. The housing is completed by a solid bottom wall insert sealed in the lower mouth of the rim and a solid top wall cap sealed to the upper mouth of the rim by procedures which involve no flowing of plastic material over or into contact with either (i) the upper surfaces of the lead fingers prior to making the wire connections to such fingers, or (ii) the chip and the wire connectors after they have been associated with the lead frame.Type: GrantFiled: December 17, 1985Date of Patent: October 27, 1987Assignee: PNC, Inc.Inventor: Clarence K.

Patent number: 4702000Abstract: The problem of unwanted residual polysilicon stringers along the sidewalls of a field oxide layer employed in direct moat wafer processing is avoided by a processing scheme in which the sidewalls of the aperture in the field oxide layer are initially tapered prior to formation of the polysilicon layer to be used for the gate electrode(s). Because of the graduated thickness of the sidewalls of the field oxide layer, the thickness of the polysilicon layer formed thereon is substantially uniform over the entirety of the substrate. As a result, during subsequent masking of the polysilicon layer to define the gate electrode(s), all unmasked portions of the polysilicon are completely etched, leaving no residual material (e.g. stringers) that could be a source of device contamination.Type: GrantFiled: March 19, 1986Date of Patent: October 27, 1987Assignee: Harris CorporationInventors: Dyer A. Matlock, Richard L. Lichtel, Jr., Lawrence G. Pearce
