Patent number: 6626720Abstract: A vacuum gap dielectric field emission triode and a method of fabrication include a conductive layer positioned on a supporting substrate and an emitter positioned on the conductive layer. A gate metal layer electrically separated from the conductive layer defines a metal bridge gate surrounding the emitter and separated from the emitter by a substantially fixed distance. The gate metal layer defines a gate opening through the metal bridge gate overlying the emitter. An anode is positioned in spaced relationship to the gate metal layer and the triode is sealed in a substantial vacuum so that the emitter is separated from the metal bridge by the substantial vacuum and the metal bridge is separated from the anode by the substantial vacuum.Type: GrantFiled: September 7, 2000Date of Patent: September 30, 2003Assignee: Motorola, Inc.Inventors: Emmett M.

Patent number: 5986878Abstract: A capacitor (100) includes first and second electrodes (102, 103) that each have an electroactive material (115, 120) disposed on a metallic substrate (105, 110). A solid electrolyte (125) including a polyacid is positioned between the first and second electrodes (102, 103). Polyacids are relatively low in cost, and their high ionic conductivity together with their thermal stability makes polyacids a viable alternative to solid polymer electrolytes.Type: GrantFiled: September 25, 1997Date of Patent: November 16, 1999Assignee: Motorola, Inc.Inventors: Changming Li, Robert H.

Patent number: 5618688Abstract: An N-channel JFET (60) and a method of forming the N-channel JFET (60) in a BiCMOS process. The N-channel JFET (60) is monolithically fabricated with an N-channel IGFET (70), a P-channel IGFET (75), and an NPN BJT (80) in an epitaxial layer (21). The N-channel JFET (60) is formed in an isolated N-channel JFET region (24), the P-channel IGFET (75) is formed in an isolated P-channel IGFET region (27), and the NPN BJT (80) is formed in an isolated BJT region (29). The N-channel IGFET (70) is fabricated in a P-type well (26) that is not isolated from other N-channel IGFET's in the epitaxial layer (21). Accordingly, the N-channel JFET (60), the N-channel IGFET (70), the P-channel IGFET (75), and an NPN BJT (80) are monolithically formed in the BiCMOS process.Type: GrantFiled: February 22, 1994Date of Patent: April 8, 1997Assignee: Motorola, Inc.Inventors: Robert H.

Patent number: 5433150Abstract: A gantry crane travelable along a pair of rails and having an overhead girder transverse to the direction of travel, first and second legs connected to the girder, a load carrying trolley movable along the girder to a first position adjacent the first leg and to a second position adjacent the second leg, first and second spaced apart motor drives mounted on one of the legs in engagement with one of the rails for moving the crane, and third and fourth spaced apart motor drives mounted on the other leg in engagement with the other rail for moving the crane. When the trolley is at the first position, the first and second drives are highly loaded and the third and fourth drives are lightly loaded. Thereby, the lightly loaded drives attempt to drive the second leg such that it leads the first leg and skews the crane. When the trolley is at the second position, the third and fourth drives are highly loaded and the first and second motor drives are lightly loaded.Type: GrantFiled: January 26, 1994Date of Patent: July 18, 1995Assignee: Harnischfeger CorporationInventors: Herbert D. Long, Jr., Robert H. Reuss

Patent number: 5394007Abstract: A junction isolated P-well is formed for high performance BiCMOS. Two dopants of opposite conductivity types are implanted and co-diffused inside an annular N-type region to form a narrow N-type buried layer positioned between two P-type regions. N-type buried layer is formed having P-type doped regions above and below the N-type buried layer so that the N-type buried layer is narrow. The P-type region above the N-type buried layer provides for a retrograde profile of the P-well formed above it. Besides the P-well isolation, the P-type region below the N-type buried layer acts as a ground plane which collects noise, which helps to prevent it from being coupled to other devices of the BiCMOS circuit.Type: GrantFiled: September 13, 1993Date of Patent: February 28, 1995Assignee: Motorola, Inc.Inventors: Robert H. Reuss, David J. Monk, Christopher P. Dragon

Patent number: 5302534Abstract: A transistor (10) is formed by utilizing an isolated well (18) within a thin epitaxial layer (14). A base mask (22) that has a base opening (23) is applied to expose a portion of the isolated well (18). A low resistance collector enhancement (24) is formed within the well (18) by doping a portion of the well (18) through the base opening (23). A base region (26) is formed overlying the collector enhancement (24) by doping the well (18) through the base opening (23). Forming the collector enhancement (24) through the base opening (23), facilitates providing the collector enhancement (24) with a small area thereby minimizing the transistor's (10) parasitic collector capacitance value, collector resistance, and transit time.Type: GrantFiled: March 2, 1992Date of Patent: April 12, 1994Assignee: Motorola, Inc.Inventors: David J. Monk, Robert H. Reuss, Jenny M. Ford

Patent number: 5167401Abstract: A hoist drive for a double hoist carrying member having a hold hoist drum, a hold rope connected to the hold hoist drum and from which the carrying member is suspended, and a hold motor for rotating the hold hoist drum to raise and lower the carrying member. The hoist drive further includes a close hoist drum, a close rope connected to the close hoist drum and from which the carrying member is suspended, and a close motor for rotating the close hoist drum to raise and lower the carrying member. During raising of the carrying member, the hold and close motors are each supplied with a.c. power at different preselected frequencies. The hold and close motors each operate along a first pair of intersecting frequency to torque curves during a raising operation in which the hold motor curve is steeper than the close motor curve.Type: GrantFiled: August 23, 1990Date of Patent: December 1, 1992Assignee: Harnischfeger CorporationInventors: Michael D.

Patent number: 4860077Abstract: A low capacitance, high performance semiconductor device is described having a sidewall emitter wherein the emitter width is relatively small (approximately 0.5 micrometers). This enables a small emitter-base interface which reduces capacitance. Additionally, the regions of the base and collector near their interface are lightly doped so that collector-base capacitance is greatly reduced.Type: GrantFiled: September 28, 1987Date of Patent: August 22, 1989Assignee: Motorola, Inc.Inventors: Robert H. Reuss, Kevin L. McLaughlin

Patent number: 4663831Abstract: Improved bipolar transistors having minimum base-collector and collector-substrate junction area are formed by using multiple polycrystalline (e.g. doped poly silicon) layers to make lateral contact to a pillar shaped single crystal device region. The lateral poly silicon contacts are isolated from each other and the substrate and extend to the upper surface of the device for external connections. The structure is made by depositing two dielectric-poly layer sandwiches, etching and oxidizing part of the poly silicon layers to provide isolated overlapping poly silicon regions, etching a first hole through both poly silicon regions to the substrate, etching a second hole to the lower poly silicon layer, and filling the first and second holes with single and poly-crystalline silicon, respectfully. A sidewall oxide is formed at the periphery of the top of the single crystal pillar for defining the emitter location without additional masking.Type: GrantFiled: October 8, 1985Date of Patent: May 12, 1987Assignee: Motorola, Inc.Inventors: Mark S. Birrittella, Hang M. Liaw, Robert H. Reuss

Patent number: 4631570Abstract: An integrated circuit power supply interconnection technique is disclosed having a highly doped, low resistivity substrate for distribution of the integrated circuit's most positive supply voltage. The substrate functions as the most positive voltage point and accomodates devices that are normally connected directly to this most positive supply voltage. A dielectric buried layer overlies a portion of the substrate and isolates the substrate supply voltage from devices that are not connected directly to the most positive supply voltage.Type: GrantFiled: July 3, 1984Date of Patent: December 23, 1986Assignee: Motorola, Inc.Inventors: Mark S.
