Method Of Making A Silicon Diode Array Target
US Patent:
4231820, Nov 4, 1980
Filed:
Feb 21, 1979
Appl. No.:
6/013120
Inventors:
William N. Henry - Lancaster PA
Assignee:
RCA Corporation - New York NY
International Classification:
H01L 21225
US Classification:
148187
Abstract:
A novel process is disclosed in which an insulating layer is formed on a N type semiconductor substrate and an array of apertures is formed through the insulating layer to expose the substrate. A film of substantially intrinsic polycrystalline silicon is deposited over the insulating layer and the exposed substrate surfaces. A masking layer having a plurality of interconnecting members is formed photolithographically on the film, the members defining an array of openings in substantial registration with the apertures. A P type doping element, such as boron, is diffused laterally into the intrinsic film beneath each masking member and is simultaneously diffused into the substrate to form a plurality of PN junctions. The lateral diffusion is controlled so that the undoped regions underlying each of the masking elements have a width less than the width of the masking elements. The masking layer is removed and the undoped regions are selectively etched to form an array of doped silicon pads that are separated by a relatively small spacing.
Bevel Angle Setting Means For A Power Tool Apparatus
US Patent:
4270427, Jun 2, 1981
Filed:
Feb 4, 1980
Appl. No.:
6/118571
Inventors:
Richard A. Colberg - Lititz PA
William T. Henry - Lancaster PA
William T. Henry - Lancaster PA
Assignee:
Black & Decker Inc. - Newark DE
International Classification:
B27B 524
US Classification:
83473
Abstract:
There is disclosed an improved bevel angle setting means for supporting and pivoting the motor-driven tool supporting assembly of a power tool apparatus including a housing equipped with a table top having an opening through which the motor-driven tool, such as a circular saw, extends; the improvement comprising means for supporting and pivoting the assembly about a pivot axis in a rapid manner whereby the bevel angle is varied. The pivoting means include a bevel handle secured to the assembly frame and a counterbalance means such as a "gas spring," which will be more fully explained hereinafter. The gas spring will act to assist the operator in adjusting the bevel angle setting for both increasing or decreasing of such bevel angle settings.
