Patent number: 5162666Abstract: A multiplexer circuit is formed of two-to-one transmission gate multiplexer (TGM) circuits (80) connected in series. A first stage TGM (80) selects among two of the input variable signals (I0,I1). Each subsequent stage TGM (70) selects among the next preceding stage output signal (81) and another one of the input variable signals (I2). Each TGM is controlled by a unique control signal (S1,S2) so that loading on the control lines is limited to one TGM circuit to improve propagation delay. The series arrangement of TGM circuits can be extended as needed (M3,M4,M5).Type: GrantFiled: March 15, 1991Date of Patent: November 10, 1992Inventor: Dzung J. Tran

Patent number: 5156909Abstract: Stress-induced deformation, and the damage resulting therefrom, increases with film thickness. The overcoming of excessive stress by the use of the Si-Al-N film material of the present invention, permits the formation of thick films that are necessary for certain of the above described applications. The most likely use for the subject film materials, other than their specialized views as an optical film, is for microelectronic packaging of components on silicon substrates.In general, the subject films have excellent adherence to the underlying substrate, a high degree of hardness and durability, and are excellent insulators. Prior art elevated temperature deposition processes cannot meet the microelectronic packaging temperature formation constraints. The process of the present invention is conducted under non-elevated temperature conditions, typically 500.degree. C. or less.Type: GrantFiled: November 28, 1989Date of Patent: October 20, 1992Assignee: Battelle Memorial InstituteInventors: Charles H. Henager, Jr., Robert W. Knoll

Patent number: 5145571Abstract: In an integrated circuit, gold interconnect metal lines are electroplated onto plating (Pd) and barrier (TiW) layers, using patterned photoresist. The photoresist is stripped and the plating layer portions thus exposed are etched to expose field areas of the barrier layer. Next, sidewall spacers are formed along each side of the interconnect lines. The field areas of the barrier layer are then etched to isolate the gold interconnect lines. The spacers offset the amount of undercut due to isotropic etching of the TiW barrier metal layer. After etching, the sidewall spacers serve to preserve the as-deposited profile of the gold interconnect lines against breadloafing in a subsequent annealing step.Type: GrantFiled: August 3, 1990Date of Patent: September 8, 1992Assignee: Bipolar Integrated Technology, Inc.Inventors: Richard H.

Patent number: 5128173Abstract: The subject invention comprises forming a plurality of positively charged ions of an ionizable coating material in an ion formation area. A deposition area is provided at a predetermined distance from the ion formation area. This deposition area is capable of being negatively charged for attracting the positively charged ions of the ionizable coating material. Next, the deposition area is negatively charged so that a uniform, substantially parallel flow path is formed for the ionizable coating material between the ion formation area and the negatively charged deposition area. A substrate is then positioned between the ion formation and deposition areas within the uniform, substantially parallel flow path, and preferably perpendicular to the flow path. The positively charged ions of the coating material are released from the ion formation area into the flow path, and are moved within the flow path by the attraction of the positively charged ions toward the negatively charged deposition area.Type: GrantFiled: September 12, 1990Date of Patent: July 7, 1992Assignee: Micron Technology, Inc.Inventor: S.

Patent number: 5128878Abstract: A remote plotting system and method is implemented in a network of computer workstations whereby a designated computer functions as a plot server. Client workstations are programmed to create plot requests from data created in a computer aided integrated circuit design and layout application. The plot server computer is programmed to A) receive plot requests in a common spooling area sent from other workstations in the network, B) perform necessary rasterization of the requested data, and C) schedule resulting plot files for the first available plotter based on a round robin scheduling mechanism. Plot requests are design file plot templates which are sets of instructions describing the specific characteristics of the desired output, and a reference to the actual design data to be rasterized by the plot server. The system incorporates a single stage queue and supports an unlimited number of plotters and client workstations.Type: GrantFiled: November 28, 1990Date of Patent: July 7, 1992Assignee: Micron Technology, Inc.Inventors: Brooklin J.

Patent number: 5124689Abstract: A computer system employs an integrated keyboard and pointing device to allow user input of alpha-numeric (typing) information, pointing direction information and pointing event information without moving the users's hands from the usual typing position on the keyboard. The new system has typing and pointing modes of operation. In the pointing mode, preassigned keyswitches are used to input pointing events, cursor speed changes, and other modifications to the system's operation. All such modifications are transparent to the operating system and application software because they are processed at keyboard interrupt level.Type: GrantFiled: September 26, 1989Date of Patent: June 23, 1992Assignee: Home Row, Inc.Inventors: Patrick J.
