Title: Manufacture of semiconductor device
Inventor: NISHIGUCHI KATSUNORI
IPC: H01L21/52
Filed: 1986-12-05
Abstract: PURPOSE:To enhance the bonding strength by a method wherein, during a grinding process, the rear of a semiconductor chip is finished in such a way that the surface roughness RMAX is a prescribed value. CONSTITUTION:The rear of a GaAs layer situated under a chip 3 is shaped to be rough, and a metallized layer 5 is formed on this rear by evaporation of Ti. In addition, an Au layer 6 is formed on the surface of this Ti layer 5 so that the layer becomes adaptable to an adhesive agent, and is glued to a substrate 1 through an adhesive-agent layer 7 of AuSn. The rear of the semiconductor chip 3 is shaped to be rough by a grinding process at the stage of a wafer. If the 'roughness' is expressed by the difference RMAX between the highest and the deepest parts on the rear of the semiconductor chip 3, the RMAX is to range from 0.2 to 0.5 (mum). This value is an especially effective value when a soldering process is applied to the GaAs chip and a metallizing process is executed by evaporation of the Ti film.

Abstract: PURPOSE:To prevent a write command signal bus or the like from being carelessly activated at the time of loading/unloading a CPU card by resetting only the CPU card by the operation of a CPU reset means, and after replacing the CPU card, restarting processing on the basis of a signal from a discriminating means. CONSTITUTION:When a fault is generated in the CPU card 2, an operation stopping means 36 stops a CPU part 32 and an inhibiting means 37 prohibits that a specific signal such as a write command signal outputted from the CPU part 32 from being sent to a bus. When only the CPU reset means 39 is driven, only the CPU card 2 is reset without resetting a PIO card 4 by means of discriminating means 40, 41, and after replacing the CPU card 2, the processing is restarted from a state obtained at the time of generating the fault. Consequently, the write command signal bus or the like can be prevented from being carelessly activated at the time of loading/unloading the CPU card 2.

Title: Cr oscillation circuit
Inventor: YOSHIZAWA HIROKAZU
IPC: H03K3/354
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To actualize the CR oscillation circuit which has an intended oscillation frequency even though a basic digital Q405 process by connecting two MOS capacitors in the opposite directions in series and applying a bias voltage to their connection point. SOLUTION: The two MOS capacitors 10 and 11 are connected reversely in series and the bias voltage is applied to their connection point through a transistor. While this circuit is in operation, the normal positive bias voltage is applied to the two MOS capacitors 10 and 11, which operate always in a storage area where voltage dependency is small. Further, the two MOS capacitors 10 and 11 so operate that as the capacity value of one increases, that of the other decreases, so the total capacity value of the series connection becomes nearly constant by mutual nonlinear cancellation. There is relatively large nonlinear parasitic capacity on the bottom surfaces of the MOS capacitors 10 and 11 and it is necessary to avoid the connections of the bottom surfaces with high-impedance terminals. For the purpose, the gate electrodes of the MOS capacitors 10 and 11 are connected to each other.
