Title: Semiconductor device and its manufacture
Inventor: MATSUNOU TADASHI
IPC: H01L21/304
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To suppress a step in a numbered part when a semiconductor wafer is numbered by a method wherein a substrate surface in the outer circumferential part of a three-dimensional step part is made flush with the substrate surface in the neighborhood and a film which is formed on the three-dimensional step part is flattened by a chemical and mechanical polishing operation. SOLUTION: A thermal oxide film as a first insulating film 12 is formed on a semiconductor wafer 11, and a CVD oxide film as a second insulating film 13 is formed on the first insulating film 12. Then, in order to perform a numbering operation, the surface of the wafer 11 is irradiated wit a laser beam BM, so that three- dimensional steps 10 are formed. A substrate material 11a which is resolidified in the formation of the three-dimensional steps and a part of the wafer 11 as a substrate are etched and removed. In addition, the CVD oxide film 13 and the thermal oxide film 12 are etched and removed. The surface of the wafer 11 in outer circumferential parts of the three-dimensional steps 10 is made flush with the surface of the wafer 11 in the neighborhood. A film which is formed on the three-dimensional steps 10 is flattened by a chemical and mechanical polishing operation.  Consequently, the uniformity of the flattening operation of the three-dimensional steps 10 can be improved.

IPC: G11B5/09
Filed: 1986-10-29
Abstract: PURPOSE:To obtain a signal level and a band width suitable for each reproducing signal of a standard mode and a long time mode, respectively, by dividing a secondary winding of a rotary transformer by a prescribed ratio, connecting them in series or connecting selectively at least one piece to a reproducing amplifier. CONSTITUTION:The winding ratio of a primary winding 21 and secondary windings 22, 23 is (m):(n):(n). In a standard mode, the windings 22, 23 of a rotary transformer 20 are connected in parallel through switches 4, 5, and a reproducing signal from a head 1 is transmitted to an amplifier 2. The number of times of winding is selected, and the attenuation of a high frequency is compensated by the equivalent inductance of the transformer 20 containing the reproducing head 1, as well, and the input capacity of the amplifier, and a resonance with others. In case of a long time mode, the windings 22, 23 are connected in series by switching the switches 4, 5. The winding ratio becomes (m):2n, and the reproducing signal from the head 1 is compensated as to its level fall, and sent to the amplifier 2 by a desired S/N. In this case, the equivalent inductance of the transformer 20 becomes four times of the case of the standard mode, and a necessary transmission band is secured by a resonance.

Title: Manufacture of semiconductor device
Inventor: OKADA KENJI
IPC: H01L21/324
Filed: 1990-09-26
Abstract: PURPOSE:To enhance the initial breakdown strength and the reliability of the underneath silicon oxide film of a polycrystal silicon thereby enabling the high yield to be gained in the device manufacture by a method wherein, after the deposition of polysilicon on an insulating film and before performing the impurity doping step, the whole body is heat-treated at the temperature exceeding the deposition temperature of polycrystal silicon. CONSTITUTION:After the deposition of a polycrystal silicon 3 on an insulating film 4 and before performing the impurity doping step, the whole body is heat-treated at the temperature exceeding the deposition temperature of the polycrystal silicon 3. For example, after the formation of a silicon oxide film 2 for element separation on a silicon substrate 1 by selective oxidation process, the gate oxidation step is performed to form the underneath gate oxide film 4. Next, the polycrystal silicon film 3 is deposited on the silicon oxide film 2 and the underneath oxide film 4 at 600 deg.C-850 deg.C. Later, after the heat treatment at 1000 deg.C for 2 hours in nitrogen atmosphere, phosphorus is diffused on the polycrystal silicon 3. Next, the polycrystal silicon 3 is patterned by dry-etching step. Through these procedures, since the stress on the oxide films is relieved by the heat treatment, the deterioration in the oxide film characteristics due to the stress can be restrained.

Title: Discharge circuit for condenser
Inventor: AOKI IZUMI
IPC: H02M1/14
Filed: 1985-11-18
Abstract: PURPOSE:To suppress initial discharge power and shorten the discharge time of a condenser, by connecting a non-linear ceramic current limiter in series to the discharge resistance and switch of a discharge circuit. CONSTITUTION:Both ends of a condenser 1 charged by a DC power source 5 via a switch 6 are short-circuited by a series connection circuit consisting of a discharge resistor 3 and a ceramic current limiter 4 via a switch 2. In this case, the ceramic current limiter 4 carries non-linear property in the voltage/current characteristic shown by figure; characteristic that while voltage applied to the limiter 4 is high, current flowing to the limiter 4 is little, but when the current is lowered to some degree, then conducting current is suddenly increased and suddenly reduced. Then, in the discharge initiation of the high voltage of the condenser 1, the discharge current is suppressed, and initial discharge power can extremely be reduced.

IPC: B41J35/16
Filed: 1989-10-02
Abstract: PURPOSE:To avoid the lock state due to the collision of a ribbon core and a slackening preventing reel part at the time of the movement of an ink ribbon by a method wherein the slackening preventing reel part and a taking-up reel part are subjected to relative separate sliding rotation in the tensioned state of the ink ribbon at a position other than the printing position due to the slackening preventing part by a pressure contact means. CONSTITUTION:A taking-up reel 29 is constituted of a slakening preventing reel part 32 for taking up an ink ribbon at a position other than a printing position relatively freely rotatable and freely separable/touchable with respect to a taking-up reel part 31 having a taking-up pawl 30 taking up the ink ribbon at the printing position fixed thereto among two or more ink ribbons 26a, 26b, 26c. The leading end part of the slackening preventing reel part 32 is brought into pressure contact with the taking-up reel part 31 to make it possible to integrally rotate both parts 32, 31. By this constitution, a pressure contact means 33 has friction force subjecting the slackening preventing reel part 32 and the taking-up part 31 to relative separate sliding rotation in the tensioned state of the ink ribbon at a position other than the printing position due to the slackening preventing reel part 32.

Title: Camera having multiplex exposure photographing function
Inventor: SAKAGUCHI TORU
IPC: G03B17/02
Filed: 1987-10-15
Abstract: PURPOSE:To inhibit the drive of a heavy load such as a motor and to release multiplex exposure photographing or a multiplex exposure mode again after restoring a power supply from a defective state to a normal state by holding the multiplex exposure mode during the period of the defective state of the power supply. CONSTITUTION:When a power supply state such as voltage drop less than a reference voltage is generated even when a battery 3 is removed or loaded after ending ME photographing, an inhibition deciding part 8 inhibits the passage of a reset signal R even when a reset switch 2 is depressed to inhibit the output of the reset signal R to a multiplex exposure mode control part 10. Since incomplete film winding is not generated and automatic winding operation is started by the mode control part 10 after restoring the battery 3 to the normal state again, normal film winding for one frame is executed and the generation of a trouble superposing the current picture to the succeeding picture to be photographed can be preliminarily prevented.
