Patent JP-2000243825-A (JP)
Title: Manufacture of semiconductor device
Inventor: SAKO TAKASHI
IPC: H01L21/8242
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent residues from being generated at the time of the etching of a gate electrode and to make it possible to suppress the deterioration of the characteristics of a transistor by a method wherein after a chemical and mechanical polishing treatment is performed on a trench film, the etching is selectively performed on only a memory cell region of the high density of a pattern. SOLUTION: A silicon oxide film is grown and thereafter, a chemical and mechanical polishing treatment is performed to form an element isolation oxide film 6. As the shaving amounts of the oxide films are different from each other, a memory cell region 30 of the high density of a pattern is formed thicker than a peripheral circuit region 20 of the low density of a pattern. The etching of the oxide film 6 in the region 30 is performed using a buffered hydrofluoric acid, for example, as an etching liquid so that the film thickness of the film 6 in the region 30 is formed in a film thickness of the same degree as that of the film thickness of the film 6 in the region 20 using a resist pattern 7 as a mask.  Thereby, even in the case where a difference between the densities of a pattern is great in the degree that an effect due to a chemical and mechanical polishing is exerted on the amount of polishing, residues are not generated in the etching of a gate electrode.

Abstract: PURPOSE:To widen the dynamic range of a luminance and to make the difference of a contrast clear by applying half blanking by an YM (half blanking) function to an entire picture so as to reduce a luminance level of the picture. CONSTITUTION:When half blanking processing to execute menu display by characters or the like is implemented to a video signal, a control signal to set the display position of a character or the like to an H level is outputted from a CPU 9, the YM function is set by the display position only and blanking control is applied. A video processor 4 is controlled so that the gain of the processor 4 is reduced for a period when the control signal is at an H level while the YM function is set. As a result, the outputted video signal is outputted in a waveform subjected to half blanking processing for the H level period. Thus, video display suitable for viewing a movie or the like is obtained.

Title: Apparatus for automatically detecting position of semiconductor pellet
Inventor: ICHIKAWA YOSHINORI
IPC: H01L21/60
Filed: 1979-04-18
Abstract: PURPOSE:To eliminate the loss of waiting time in an apparatus for automatically detecting the position of a semiconductor pellet by automatically setting the waiting time upon stoppage of the moving X/Y stage in response to the vibration of a photoelectric detecting head. CONSTITUTION:The surface of a semiconductor pellet 9 on a bonding base 10 is electrically scanned by a photoelectric detecting head 5 installed through a holder 6 on X/Y stage 7. An electric signal from the head 5 is processed in a signal processor 8 to apply the feature of the pellet 9 into a CPU4. The CPU4 produces a pulse of the result to a stage controller 11 so as to move the stage 7. Further, a vibration detector 1 detects the vibration of the head 5 and applies a signal to a vibration signal processor 2, which processes the signal and applies the signal output to a comparator 3. The comparator 3 compares whether the signal output incorporates predetermined vibration amplitude or not and applies the result to the CPU4. If the result represents not the predetermined vibration amplitude, the comparator 3 resets the counter in the processor 8 to allow the CPU4 to produce a start pulse for detecting the position to a photoelectric detecting head 5.

Abstract: PURPOSE:To increase the life of an expansion piston and an expansion piston ring which form an expansion space and reduce restrictions to the heat resistance and durability of their materials, structures, etc., by forming a heat insulating space between a heating part and an expansion space. CONSTITUTION:A cooling part 23, a regenerator 24, and a heating part 25 are located between a compression space 13 and an expansion space 19 in order from a compression space 13 side. By this, a heat insulating space 26 is formed between the heating part 25 and the expansion space 19.

By forming the heat insulating space 26 between the heating part 25 and the expansion space 19, the expansion space 19 is insulated thermally from the heating part 25 to prevent the expansion space 19 from being heated to high temperature. In addition, by installing the cooling means 27 between the insulating space 26 and the expansion space 19, the expansion space 19 is more insulated thermally than from the heating part 25. Thus the life of an expansion piston, etc., which forms the expansion space 19 is increased.

Title: Signal generating apparatus
Inventor: ARASAWA EIKI
IPC: G01R31/3183
Filed: 1988-02-29
Abstract: PURPOSE:To prevent the occurrence of a voltage shock by a method wherein a terminal voltage of a device (DUT) to be inspected to which an output of a high-speed driver is given is monitored by a comparator and corrected by an A/D converter, an output of a DC driver is controlled and the drivers are switched over at the time of an equal voltage. CONSTITUTION:A switch SW1 being turned ON, a signal is given from a driver 1 to a terminal A of DUT 4, and after an inspection is ended, an output of the driver 1 is maintained to be E1=VD with SW1 left to be ON. Then, the voltage VD is taken in a buffer 11 by turning SW2 ON and SW3 OFF. VD is not varied since an input resistance of the buffer 11 is high. An output of the buffer 11 is compared with an output E2 and a signal SC is given. While the signal SC shows E2<VD, a control circuit 16 instructs a D/A converter 14 to increase E2 and turns the SW3 ON when E2=VD is reached at last. According to this constitution, E2=VD is reached automatically in a short time, the SW1 is turned OFF thereafter, while the SW2 and the SW3 are turned ON, and a transfer is made to a DC test of the DUT without causing any voltage shock.
