Title: Muting circuit
Inventor: TSUN KENZOU
IPC: H03F1/00
Filed: 1984-01-29
Abstract: PURPOSE:To suppress the abnormal sounds produced by the instantaneous application of a power supply by setting freely the muting time at optional length to secure the slow conduction of a switching transistor. CONSTITUTION:The relations VF1(I1)<VF2(I2) and I2>I3 are satisfied between output currents I1-I3 of constant current sources 22, 24 and 34 and forward descending voltages VF1 and VF2 of diodes 26 and 28 respectively. When a power supply switch 4 is closed, the sources 22-34 are actuated to produce the voltage VF1 at the diode 26 with the terminal voltage set at VA. At the after this time point, a capacitor 30 is charged. The voltage VF2 is produced at the diode 28 after a fixed period of time elapses with the terminal voltage set at VB. Thus VA<VB is satisfied, and the charging voltage of the capacitor 30 is set at VB- VA. A transistor TR12 conducts slowly when its base potential reaches the threshold level and flows a constant current I3.

Filed: 1985-01-29
Abstract: PURPOSE:To facilitate handling of wafers and diminish dispersion in junction diamters, by making an electrode on an active layer formed on a backward conductiontype substrate and applying mesa-etching to the active layer through the mask of this electrode. CONSTITUTION:A P-type low resistance substrate 1 is laminated with an N-type high concentration layer 2 and an N-type low concentration layer 3 and finally with an N-type high concentration layer 4 for contact to form an active layer, on which an homic electrode 5 is formed. Using the electrode 5 as a mask, the active layer is mesa-etched and the wafer is stuck onto a quartz plate 8 with photoresist 7, the substrate 1 out. After subjected to lapping and etching to make the substrate 1 sufficiently thin, an electrode 6 is formed on the surface of the substrate 1. Just as stuck to the quartz plate 8, the wafer is then subjected to edge cutting and chip isolation. Thus as well processes including electrode formation are conducted in such a condition that a wafer is thick or stuck to a quartz plate, the wafer is easily handled. In addition, as mesa- etching is applied to a thin, active layer, dispersion in junction diameters becomes smaller.

IPC: H01L49/00
Filed: 1992-01-30
Abstract: PURPOSE:To lower the gate voltage at the time of electron emission by a method wherein a sacrifice material made to adhere to the point of a cathode and an insulating layer on the periphery of the cathode are removed. CONSTITUTION:A circular mask 2 of a diameter of 1 to 2mum or thereabouts is formed and a cathode 3 is formed by etching or the like using this mask 2. After the mask 3 is removed, an insulating material 4 having a viscosity, such as a water-glass, is applied. At this time, the film thickness of the material 4 is made thin to such an extent that the material 4 does not adhere to the periphery of the point of the cathode. For example, a voltage is applied to a cathode through the back side of a substrate 1, the point of the cathode is positively charged, a sacrifice material 5, such as permalloy, is made to adhere to the point of the cathode according to this charge by a plating method or the like and the point of the cathode is wrapped with the material 5. After that, a gate material 6, such as a molybdenum material, is deposited, the material 5 is removed and an insulating material 4 on the periphery of the cathode is etched. Thereby, even if a gate voltage is lowered, the electric field on the point of the cathode can be increased and electrons can be efficiently emitted.
