Title: Thin film transistor and manufacture thereof
Inventor: MATSUI MAKOTO
IPC: H01L27/12
Filed: 1987-06-19
Abstract: PURPOSE:To obtain a gate insulating film with a good interfacial characteristic and with a desired thickness even in use of an insulating substrate of 700 deg.C or less in its heat-resisting temperature, by forming a piled insulating film of a desired thickness on an oxide film and next by using these bilayer films as the gate insulating film. CONSTITUTION:A polycrystalline Si film 2 is formed on a light-transmissive insulating substrate 1 at a substrate temperature 550 deg.C for example by a superhigh vacuum evaporation method. After an appropriate mask is used to define an ion implantation region, p<+> ions are implanted there and the substrate is provided with heat treatment for two hours at 55 deg.C in an N2 atmosphere so that an n<+> layer 3 is formed on the source and drain regions. Subsequently the substrate temperature is maintained to be 560 deg.C and microwave discharge in a cusp magnetic field is performed in an oxygen atmosphere for 30 min., so that the polycrystalline Si film 2 is oxidized to form an oxide film 41. Further a normal pressure CVD method is used to stick an SiO2 film 42 on the film 41 at the substrate temperature 415 deg.C, so that a bilayer film composed of the plasma oxidizing film 41 and the SiO2 film 42 is used as a gate insulating film. Hence a gate insulating film with a good interfacial characteristic and of a desired thickness can be obtained on even the insulation substrate of 700 deg.C or below in its heat-resisting temperature.

Title: Decoder circuit
Inventor: MURASAWA KEIJI
IPC: H03M5/04
Filed: 1979-11-27
Abstract: PURPOSE: To obtain a decoder circuit having a quick response at the fall, by securing an immediate response of the multiemitter transistor to current reduction of the buffer load line which is caused by a slight discharge of the parasitic vibration.  
     CONSTITUTION: The current flowing through the multiemitter transistors TR201, 307 and 308 each which form an emitter connected circuit in mutual pairs possesses two types of value according to the input signal voltage. Thus ICSflows to the nonselected TR, and IB flows to the selected TR each. The extent of voltage fluctuation of the buffer lines 21W26 is nearly identical to the voltage drop of the nonselected resistance 202, and the charge/discharge electric charge of parasitic capacity decreases with reduction of the extent of voltage fluctuation of the buffer load line. On the other hand, a quick response is obtained for the multiemitter TR current from IB to ICS since the TR can respond immediately to the potential reduction of the buffer load line which is caused by a slight discharge of the parasitic capacity. And the responding performance can be accelerated furthermore at the fall.

Title: Molecular beam crystal growth apparatus
Inventor: MANNOU MASAYA
IPC: H01L21/26
Filed: 1986-06-27
Abstract: PURPOSE:To prevent attachment of residual molecular beams in a growing chamber to an inspection hole, by providing a trap part having a cooling means between the growing chamber and the inspection hole. CONSTITUTION:Water, liquid nitrogen, liquid helium or the like as a refrigerant is made to flow around a trap part 11 between a growing chamber 1 and an inspection hole 9, and the trap part is sufficiently cooled. Molecular beams of Ga and As, which do not contribute to the growing, are immediately adsorbed by a liquid nitrogen trap in the growing chamber 1 or exhausted by a vaccum pump. Part of the beams remain in the growing chamber 1 and come to the vicinity of the window 9. However, the molecular beams (mainly As) are adsorbed by the sufficiently cooled trap part 11 before the beams reach the inspection hole 9. Thus the beams are hardly attached to the inspection hole 9.

Abstract: PURPOSE:To provide a bus transfer device which executes '0'-extending with a small hardware quantity. CONSTITUTION:When the output of a base register 3A is transmitted to a bus 1, at first, a precharge control circuit 2 is activated by a precharge control signal P/ and bus lines 11-18 are precharged to be '1' by the precharge control circuit 2. Then, tri-state buffers 51-54 are activated by an enable signal ENO. The output of the base register 3A is inverted in the tri-state buffers 51-54 and its inversion signal is transmitted to the bus lines 11-14 of a low-order 4 bits. At this time, bus transfer is executed by negative logic in this configuration so that the output of the base register 3A is '0'-extended so as to be transmitted to the bus lines 1<5>-1<8> of the high-order 4 bits. Therefore, the tri-state buffer for '0'-extending is unrequired and hardware quantity is reduced.

Abstract: PURPOSE:To contrive the prevent the aluminum corrosion at the pad section due to water infiltration by a method wherein the diameter of a contact hole is made smaller than that of a bonding wire connected to the bonding pad. CONSTITUTION:An Si nitride film 4 is adhered over the entire surface so as to cover a conductive layer 3, and in the nitride film 4 the aluminum pad 5a and wiring 5b are formed by filling the contact holes 8a and 8b, respectively, after the holes 8a and 8b having diameters smaller than that of the bonding wire 9 are bored. Water infiltrating along the gap 12 between the wire 9 and a sealed resin 11 easily reaches the pad 5a and then corrodes the periphery 13 of the pad 5a. Since the diameter of the hole 8a is smaller than the bonding wire 9, and the hole is firmly closed by the hydrophobic Si nitride film 4 which repels water and by the pad 5a, the disconnection between the pad 5a and the lower conductive layer is almost perfectly prevented.

CONSTITUTION:Firstly, a trigger 3 of a spray gun 1 is pulled to a transfer a liquid to be jetted to a nozzle device 6 under pressure. At this time, when a rotary ball 11 is kept at the closing position, the liquid is filled in a hollow part 8 and to the tip of a through hole 14 through a supporting plate 10, but is prevented from jetting into spray. Next, when an adjusting lever 15 is operated in this state, the ball 11 is rotated to communicate the hole 14 and a jetting hole 13 with each other, thereby the liquid is jetted 13. At this time, a liquid quantity is changed by the shifting quantity of lever 15, then the lever 15 is held up when the liquid quantity reaches a desired one. Then at the next spraying, said desired quantity is obtained only by pulling the trigger 3, and further, when the quantity is required to change while spraying, the change to a desired quantity is easily performed by operating the lever 15 in the same manner.
