Granted: 2000-07-11
Abstract: The present invention provides a new packaging form of semiconductor diode which is fabricated by using the low-temperature cofired ceramic (LTCC) technology.  Due to the sintering mismatch between metal and ceramics, the undesirable cofired defects such as chamber, separation, and cracks are easily found in the final product.  To reduce the non-uniform shrinkage in X-Y direction of LTCC and to further control the dimension of ceramic components precisely, a flexible constraining layer, which becomes porous during firing, is stacked onto the LTCC tapes.  The fabrication method includes the steps of: (a) providing a low-temperature cofirable ceramic (LTCC) green tape having a through hole for positioning a diode die; (b) positioning a diode die in the through hole; (c) sandwiching the diode die between two LTCC green tapes having printed conductor patterns facing the electrode surfaces of the diode die; (d) stacking layers of high-temperature cofirable ceramic (HTCC) green tapes to the top and bottom surfaces of the LTCC assembly; (e) laminating the multilayered ceramic tapes into a compact such that the conductor patterns connect to the electrodes of the diode die; (f) firing the laminate to form interconnected porosity in the HTCC tapes and densify the LTCC tapes and inner conductor; (g) removing the porous HTCC tapes from the fired ceramic assembly; and (h) forming end terminals, and solder-plating the end terminals to finish a ceramic chip of the semiconductor diode.

Further, the electrostatic holding apparatus does not generate impurities that would otherwise contaminate semiconductor devices. In addition, neither fine cracks nor pores remain, so that the electrostatic holding apparatus excellent in terms of withstand voltage.

Title: Semiconductor device and process of making the same
Inventor: ENDO SHUNICHI
IPC: H01L23/532
Filed: 1999-10-05
Granted: 2001-04-11
Abstract: In a semiconductor device, a connecting layer is provided between a silicon-containing insulating film SiO2, or a metallic wiring layer, and a fluorine-added carbon CF film so as to increase intimate connection between the two layers. In order to achieve this purpose, SiC film-forming gases, such as an SiH<4> gas and a C2H4 gas, are formed into a plasma for forming a connecting layer SiC film 200 on the upper side of the SiO2 film 110. Then, an SiH4 gas and a C2H4 gas, as well as a C4H8 gas and a C2H4 gas, are introduced to conduct a film-forming gas switching process for one min. Thereafter, the CF film-forming gases, such as the C4H8 gas and the C2H4 gas, are formed into a plasma for forming a CF film 120 on the SiC film 200. As such, during the film-forming gas switching process, the film-forming gases for both SiC and CF films are present. Therefore, near the boundaries of the SiC film 200 and the CF film 120, Si and C can be combined with one another beyond either sides of the film-forming gases, thereby increasing an intimate connection between the films, i.e. improving an intimate connection between the SiO2 film 110 and the CF film 120.

Title: Image sensor and method for driving the same
Inventor: KWON OH-BONG
IPC: H04N5/335
Filed: 1999-10-28
Granted: 2001-07-01
Abstract: An image sensor and a method for driving a pixel array in the image sensor are to prevent unnecessary power consumption by controlling transistors contained in a unit pixel. The unit pixel contains a transfer transistor, a reset transistor, a drive transistor and a select transistor. Under a correlated double sampling, within a predetermined period after the reset transistor is turned off, the select transistor is turned on to output a reset voltage level transferred from a voltage source as a unit pixel output signal through the drive transistor. As a result, the voltage source is not directly coupled to an output of the unit pixel to thereby effectively reduce unwanted power consumption and enhance the resulted picture quality.

Title: Method and apparatus for controlling a system using hierarchical state machines
Inventor: VIVIANI GARY L
IPC: G06F19/00
Filed: 1999-12-22
Granted: 2001-12-01
Abstract: A method and apparatus for controlling complex systems includes hierarchically coupled subsystems representing operative functions of the system. The hierarchically coupled subsystems are coupled to collect command data from a user and signal data from the system. Each subsystem may include one or more state machines and one or more digital signal processing and conditioning unit (DSPCU) objects. The DSCPU objects accept process commands and convert control system signals into states for further processing by the state machines. Associated with the DSPCUs of each subsystem is a data flow diagram for dictating an order of flow of commands and signals at the DSPCUs. A method of controlling the system represented by the hierarchically coupled subsystems schedules the execution of the subsystems according to an execution protocol. According to the execution protocol, for each cycle of execution of the system, the hierarchically coupled subsystems are first analyzed in ascending order of the hierarchy, with DSPCU objects being analyzed in data flow order before state machine objects, and then in descending order of the hierarchy, with state machine objects being analyzed before DSPCU objects. During the ascending execution of the hierarchy, signal data received from only those objects that are relatively lower in the hierarchy are used to update the state of any given object. During the descending execution of the hierarchy, command data received from only those objects that are relatively higher in the hierarchy are considered when updating the state of any given object.
