Title: Manufacture of semiconductor device
Inventor: TAKENAKA KAZUHIRO
IPC: H01L27/105
Filed: 1989-03-31
Abstract: PURPOSE:To improve characteristics of a capacitor using a ferroelectric film by forming a lower electrode by sputtering, and then sputtering the ferroelectric film continuously while holding in vacuum in the same vacuum unit. CONSTITUTION:A chamber 1 of a sputtering apparatus has a preliminary evacuation chamber 2 for feeding a wafer, and a wafer preparing chamber 3 for taking the wafer to two sputtering chambers 4, 5. After a lower electrode is sputtered, the first chamber 4 is again evacuated to the same high vacuum degree as that in the other chamber. The sputtered wafer is conveyed to a predetermined position 11 of the second chamber 5 without exposing the wafer with the atmosphere. The ferroelectric film is sputtered in the second chamber, but PZT (PbZrO3/PbTiO3=525/485) is, for example, used as a target 12, Ar/02=90%/10% is used as sputtering conditions, 2mmTorr is used as gas pressure, 200W of power is used, and approx. 5000A is sputtered. Thus, the characteristics of a capacitor using the ferroelectric film are improved.

Abstract: PURPOSE: To shorten a contact bounce time and to increase the speed and the contact pressure of a movable contact by providing a circuit means whereby a voltage to be impressed on a relay coil is made higher than a rated voltage of the relay coil only for a short time in the initial period of a relay operation and made the rated voltage thereafter. CONSTITUTION: While one end of a transistor Tr1 is connected to a supply voltage, a drive signal from a control circuit 91 is impressed on the base of the transistor Tr1 and thereby the supply voltage being a rated voltage is impressed on a relay coil 2. While one end of a transistor Tr2 is connected to a boosting circuit 10, on the other hand, the drive signal from the control circuit 91 is impressed on the base of the transistor Tr2 and thereby a voltage boosted by the boosting circuit 10 to be higher than the supply voltage is impressed on the relay coil 2 only for a short time in the initial period of operation of a relay R. According to this constitution, it is possible to shorten a contact bounce time and to increase the speed and the contact pressure of a movable contact 7 and thus the lifetime of the contact can be prolonged.

Title: Output controlling method for thin film destribution feedback laser
Inventor: MATSUDA AKIHISA
IPC: H01S3/10
Filed: 1978-07-06
Abstract: PURPOSE:To control output intencity of a laser by utilizing mutual action of two destribution feedback laser lays in a thin film. CONSTITUTION:Two diffraction grids 2 and 2' having two different cycles T and T' are grooved on a glass base 1. Pigment scattered areas 4 and 4' are formed by scattering luminous pigments only over the two sections where the grids are located. When an ultra violet lay 5 irradiates the area 4 and excites the pigments, the area 4 produces laser vibration by means of the destribution feedback principle, and emits a laser lay with a wave length of lambda=2nT, where n is the refractive index of a polyurethane film 3. The laser lay goes to both right and left in a light-leading wave path. Then another ultra violet lay 5' irradiates the area 4', a laser lay 7 with a wave length of lambda=2nT' is emitted. In this case when the lay is observed from the right side, the laser lay 6 is very dim and the strong laser lay 7 is observed which means that the laser lay 6 can be controlled by irradiating the ultra violet lay 5' on the area 4'. When it is observed from the left side, the reverse phenomenon can be seen. Thus the laser lay 7 is controlled by irradiating the ultra violet lay 5 on the area 4.

Abstract: PURPOSE: To realize the reduction of the microprogram steps residing in the control memory unit, by executing the contents of the access enable work register by the microprogram and in the form of the next microorder.  
     CONSTITUTION: When the interruption request is given to microprogram MP control part from the maintenance or diagnosis device, the MP takes the data given from data bus 420 into work register 400 via work register selector 410. Before use of the contents of register 400 as the microorder, the MP executes the contents of registers 400 to microorder address shunt register 100 and in the form of the microorder, and then sets the control memory address to be read and executed to the order sequence field with designation for the shunt. In that case, the diaplay of return is always secured at the area corresponding to the order sequence field of the data which was read in from the diagnosis device or the like. This is for the fact that the microorder is read and executed automatically from control memory device 500 which is designated by the address shown by register 100 after the data read-in is executed as the microorder.
