Title: Field-effect transistor
Inventor: FURUKAWA YOSHITAKA
IPC: H01L29/788
Filed: 1979-12-18
Abstract: PURPOSE:To improve the high frequency characteristics by reducing a floating capacity and improving the working speed of the subject transistor using a method wherein a Si or a Ge substrate, having a deep level in a crystal, is used and worked at a low temperature as the substrate of the field-effect transistor. CONSTITUTION:The regions for a source 10 and a drain 11 are formed on the Si or the Ge substrate, whereon the impurities having the deeper level (for example, Au, Fe, Ni and Mn) are doped, by heat-diffusing shallow leveled impurities or by injecting ion. Then an oxidation film is provided on the surface, the ohmic contact of the source and drain electrode 13 is formed and a gate electrode 14 is provided. When this field-effect transistor is worked in the low temperature atmosphere at 77 deg.C, the carrier in the substrate 9 is trapped by the deep level, the density of the carrier is turned almost to zero and the floating capacity is reduced. Also, as the working is performed in the low temperature, the mobility of electron is increased and the high frequency characteristics can be improved.

Title: Semiconductor device
Inventor: KAWAGUCHI MANABU
IPC: H01L21/02
Filed: 1988-06-30
Abstract: PURPOSE:To indicate test results without destroying elements and wiring by providing an inferior product identification symbol engraving area beside a circuit forming area or on the uppermost cover layer of a semiconductor chip. CONSTITUTION:A defective product identification symbol engraving area 4 provided beside a circuit forming area 2 is formed in the same process as that for bonding pads 3. When, for example, a semiconductor device is discriminated as a defective product as a result of a product test performed with semiconductor elements being arranged on a wafer, a symbol indicating an inferior product is engraved in the area 4 by using, for example, a laser marker. Therefore, the elements and wiring constituting a circuit are not destroyed by the engraving work. Whether a product is acceptable or to be rejected can be discriminated in the next process by means of the symbol engraved in the area 4. Since the elements and wiring constituting the circuit are not destroyed and the inferior characteristics are maintained, the real cause of the defects can be checked later.

Title: Earth detecting system of trunk line
Inventor: SATOU KAZUHIRO
IPC: H04Q3/58
Filed: 1981-10-16
Abstract: PURPOSE:To obtain a central office trunk which can be installed regardless of the starting system of the trunk line, by using a loop current detecting circuit. CONSTITUTION:The voltage is supplied only to a link line L2 from a central office exchange COX when a trunk line CL applies an earth starting system and is free. No current is applied to a loop current detecting circuit CD in a central office trunk COT. Thus transistors TR1-TR4 are turned off, and a ground detecting circuit GD is cut off from a communication line. The trunk COT is ready to transmit the signal to the line CL, and the earth is connected to a line L2 via a resistance R. Thus a relay B of the exchange COX starts to supply the earth to a chip line L1. Then TR1 and TR2 are turned on, and the circuit GD is connected to a call line (L1 side). No modification is required to the trunk COT even though it is connected to the line CL of a loop starting system.

Filed: 1986-07-14
Abstract: PURPOSE:To facilitate the adjustment and control while eliminating setting work of terminals, by providing each terminal with a counter to count a clock applied to respective clock input terminals of the terminal units. CONSTITUTION:Terminal units 5 are each provided with a counter 18 to count a clock applied to respective clock input terminals 14 thereof 5. When the number of clock pulses outputted from a main unit 1 is M, the number K of clock pulses counted with the counter 18 is given by K=M-(N-1) according to the stage number N of the terminal units 5. In other words, the counter 18 of the first-stage terminal unit is count K=M and the counter 18 of the second stage terminal unit is to count K=M-1. In this manner, the counter 18 gives counts as value obtained from the number M of pulses outputted from the unit 1 and the stage number N of the terminal unit involved by the expression of M-(N-1). This allows the attaching of the number of terminal unit to the counter 18 thereby facilitating the adjustment, eliminating numbering work.
