Title: Manufacture of semiconductor integrated circuit device
Inventor: AOKI HIDEO
IPC: H01L21/8239
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To form a wiring part and a connection hole easily, by flattening a step part between a memory array and a peripheral circuit in a DRAM with a structure of a stacked capacitor. SOLUTION: First layers of wirings 18A and 18B are formed on a BPSG film 17 that covers an upper electrode 16 in a capacitive element (C) used for data accumulation. In this case, wirings 18A and 18B are formed only in a peripheral circuit and not in a memory array. As a result, when a silicon oxide film 19 is etched back and flattened, the quantity of etch back is increased for the silicon oxide film 19 as a high step part in the memory array.

Title: Manufacture of semiconductor device
Inventor: TANIZAKI YASUNOBU
IPC: H01L29/73
Filed: 1988-06-24
Abstract: PURPOSE:To reduce the influence of an element connection due to the irregularity in the depths of a buried layer by opening a recess partly on the surface of an n-type semiconductor layer, forming the layer as a base layer thereunder, forming a p-type layer around the n-type layer as the emitter of a vertical p-n-p transistor. CONSTITUTION:An n-p-n transistor Q1 is formed in a region I, and a vertical p-n-p transistor Q2 is formed in a region II. In this case, since the n-type base 1 of the vertical p-n-p transistor is brought into contact with an emitter 2 (p-type layer) in a relatively low surface concentration, the impurity concentration of the base can be increased that much, and since the base is diffused from the surface of a recess, it is brought into contact with a buried p-type layer 6 in a relatively high base concentration. Accordingly, the modulation of the base concentration to be affected by the influence of the irregularity of the position of the buried layer due to the variation in the thickness of an epitaxial layer is alleviated.

Abstract: PURPOSE:To manufacture a semiconductor integrated circuit in simple steps by patterning a conductor film formed in the same manufacturing step to simultaneously form a base leading electrode and a gate electrode. CONSTITUTION:The base leading electrode 8 of a bipolar transistor Q1 and the gate electrode of a MISFET are simultaneously formed by a step of forming a conductor film on a whole surface and patterning the film.

Title: Chattering eliminating circuit
Inventor: TOTSUKA TADAO
IPC: H03K5/1252
Filed: 1980-11-04
Abstract: PURPOSE:To reduce the device scale, by holding an input signal level in the state before the input signal is switched by a signal semiconductor switching element and thus eliminating chattering. CONSTITUTION:The output of a semiconductor switching element, which receives an input pulse signal through an input resistance 4, is fed back positively by a noninverter N-INV of an integrated circuit to set the input level of the N-INV to a value higher than the threshold before switching of a movable piece C of a changeover switch 2. That is, when the movable piece C is stable in the + potential side, an input level Vin of the N-INV is higher than the threshold voltage of the threshold level; and when the movable piece C is stable in the 0 potential side, the Vin is lower than the threshold voltage of the L level. Therefore, a resistance 4< a resistance 3 is true. Thus, chattering is eliminated only by a signal switching element and two resistances to reduce the device scale.

Title: Pattern position detecting device
Inventor: NAKAJIMA MASAHITO
IPC: G01B21/00
Filed: 1981-09-30
Abstract: PURPOSE:To detect the pattern position highly accurately, by obtaining the pattern data of the pick up signals of images in detecting windows from the preset sizes of the detecting windows and the distances from chip corners, and selecting the pattern whose difference from the reference projection value is smallest among the patterns which are shifted by a plurality of bits. CONSTITUTION:A pad pattern 90 is processed 10 by a pick up system such as a TV camera. The image signal is converted 11 into digital data having three values at every picture element, and the result is stored in a frame memory 12. The corners of a semiconductor chip is detected 13 from said data, and the pattern detecting windows 91 and 92 are determined by the corners. Then the data in the detecting windows are summed for every column unit, and a numerical data A0 for one line is obtained. By using this, the shift processing of + or -n bits in  the row direction is performed. Then the difference between the data A1-An and A-1-A-n and the preset reference projection value 17 for every bit is average by a reference projection value subtracting part 16 and a bit difference total  sum averaging part 18. This is judged as the optimum address. The position detection is made possible by a minimum value detecting part 19, an optimum matching address output part 20, and a pad center address computing part 21.

Filed: 1995-06-22
Abstract: PURPOSE: To shorten image of obtaining a set of cardiac images, by a method wherein a frequency selectable RF inversion pulse related to a first group of fast NMR pulse systems during each heart beat cycle is adjusted and passes zero in magnetization by the delay time same as in the case of the following group of fast NMR pulse systems to suppress fat. CONSTITUTION: First and second groups of (n) view segments respectively forming groups 210 and 212 of NMR pulse systems gain a view depending on relative time to the center of each group of fast gradient echo segments from a cardiac trigger signal 200. Normally, one group is composed of 8 segments to obtain a compromise between physical motion averaging time resolutions and image gaining time of each image, and the gaining of data is completed by sixteen cardiac trigger signals. This time length is just enough to let most patients stop their breathing. Spectrum selectable RF inversion pulses 214 and 215 are added ahead of groups of the NMR pulse systems 210 and 212 with n=8 segments, thereby achieving the suppression of fat.

Title: Resetting circuit
Inventor: MAEDA NOBUYOSHI
IPC: G06F1/24
Filed: 1981-09-30
Abstract: PURPOSE:To secure sufficient reset time and to prevent a microprocessor from malfunctioning by forcibly grounding a connection point when a DC power voltage drops momentarily below a permissible level. CONSTITUTION:When the voltage at a terminal drops below a lower-limit set value at time (t), a waveform 33 is applied to a detecting circuit 8 to obtain an output waveform 34, and an output waveform 35 is also obtained from a switch circuit 9. A resistor 10 has a reference resistance value, so a capacitor 3 is discharged momentarily to the ground level. After the voltage at the terminal 5 starts recovering, the grounded state of the capacitor 3 is released at time t2, and the discharge is restarted through a resistance 2 to obtain a waveform 36. Namely, the potential at a connection point 6 starts rising at t2, and time tr up to a rise to a threshold level 37 is secured as reset time, thereby restarting normal operation thereafter.

Abstract: PURPOSE: To prevent the release of an inner surface resin coating layer from a metal pipe and the generation of unevenness by externally fitting a heat-shrinkable synthetic resin pipe to an inner surface resin coated metal pipe and heating the synthetic resin pipe while pressing the inner wall surface thereof to shrink the same. CONSTITUTION: An adhesive is applied to the outer surface of an inner surface resin coated metal pipe and a synthetic resin pipe 8 is externally fitted to the metal pipe and hollow rubber elastomers 53, 63 are inserted in the inner surface resin coated metal pipe to attach caps 5, 6 to the metal pipe. Next, compressed air is sealed in the hollow rubber elastomers 53, 63 from air pipings 56, 65 to seal the inside of the inner surface resin coated metal pipe. Next, compressed air of which the pressure is slightly lower than that of the hollow rubber elastomers 53, 63 is sealed in the inner surface resin coated metal pipe from air piping 55. When the whole is inserted into a heating furnace, the synthetic resin pipe 8 is thermally shrunk to be closely bonded to the inner surface resin coated metal pipe.  The inner resin coating layer is restrained by the hollow rubber elastomers 53, 63 at heat shrinkage of the synthetic resin pipe 8 to be prevented from flying out and is not peeled because the inner surface resin coated metal pipe is also internally pressurized.
