IPC: H01L21/8238
Filed: 1988-01-26
Abstract: PURPOSE:To easily enable increasing latchup dielectric strength without using an epitaxial layer, by installing a low resistance region under a well. CONSTITUTION:After an N<+> low resistance region 1 is formed on an N<-> silicon substrate 2 by thermal diffusion method, and a P-well 3 is formed, a field oxide film 4 is formed by thermal oxidation. Further, by implanting P-type ion and N-type ion, an N<+> drain 7, an N<+> source 6, a P<+> drain 9 and a P<+> source 8 are formed. A polycrystalline silicon gate 10 is arranged, aluminum is stuck by sputtering method or vapor-deposition method, and electrodes and wirings are arranged by photolighography technique to constitute a CMOS. A parasitic PNP transistor T1 and a parasitic NPN transistor T2 generating between a power supply terminal VDD and a ground terminal GND decrease, because a substrate resistance Rsub is a low resistance region 1. As a result, the current value for which latchup occurs increases, thereby preventing latchup very easily.

Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To enable automatic re-detection of a mark even when mark detection fails in an initial measurement range. SOLUTION: The apparatus includes a mark detection system 1 for measuring a mark on an object in a predetermined measurement range and a control system 2, when mark detection failed in the measurement range, for judging presence or absence of a part of a mark in the vicinity of boundaries of the range on the basis of a detection result of the mark detection system 1 and, when judging that the mark part is present, for modifying the measurement range in such a manner that the entire mark is detected by the mark detection system 1. Accordingly, when the apparatus is applied to a light exposure apparatus, alignment measurement can be successfully achieved even in such a case that it ended in an alignment error in the prior art, reduction of a wafer positioning accuracy or reduction of an apparatus processing efficiency can be avoided.

Title: Flow rate detector, terminal equipment and meter inspection system using these detector and equipment
Inventor: KAWAOMO IKUO
IPC: G06Q10/00
Filed: 1994-02-10
Abstract: PURPOSE:To prevent the reading and input mistakes in a meter inspection mode and to improve the efficiency of the meter inspection jobs by converting the detected flow rates of the city water, gas, electricity, etc., into the bar code data and displaying these flow rates in bar codes. CONSTITUTION:A flow rate detector 2a detects the used amounts of city water, gas, electricity, etc., and an A/D converter 2b converts the flow rates detected by the detector 2a into the digital value. These digital flow rates are numerically shown on a display counter 2 by a CPU 2c. The CPU 2c also reads the bar code patterns out of a memory 9 in response to those flow rates changing momentarily and displays these patterns on a liquid crystal display 3 at each prescribed time interval counted by a counter 10. Thus a meter inspector turns a bar code reading scanner of his portable terminal equipment toward the display 3 to read the displayed bar code pattern. This read pattern is shown on the display screen of the portable terminal equipment and also stored in an internal memory. Then this bar code pattern can be inputted to a host computer.

Title: Absolute fluxmeter of superconduction quantum interference
Inventor: YAMASHITA TSUTOMU
IPC: G01R33/035
Filed: 1981-02-09
Abstract: PURPOSE:To realize the absolute measurement of magnetic flux, by using Josephson elements which have the superconduction properties to be reduced for every invasion of the magnetic flux quantum and gives an incomplete period answer to the magnetic flux. CONSTITUTION:A number of superconductive metallic fine particles 1 are formed on a substrate 2, and a spot connection is given to the particles 1. Then the surface of each particle is oxidized to obtain an oxidized film. Furthermore, the similar metallic fine particles are formed on the oxidized film. This operation is repeated to obtain a 2-dimentional or 3-dimentional Josephson distribution circuit network containing Josephson elements 3 between the metallic fine particles. Then an external magnetic field phie is applied to a reticular equivalence circuit consisting of a Josephson element J and an inductance L. As a result, the superconduction properties of the distribution circuit network is reduced with every invasion of the magnetic flux quantum. Accordingly the stabilized state is reduced with increment of the magnetic flux quantum number (n). Thus the AC magnetic flux phirf and the DC magnetic flux phiDC are applied from an LC resonance circuit to detect phiDC=0.

Abstract: PURPOSE:To reduce the size of the multislit light projector for making three- dimensional measurement by projecting coded multislit light to an object to be measured. CONSTITUTION:The diameter of collimated beams of light from a light source 1 consisting of a semiconductor laser, etc., is reduced by a beam expander 6 and is made incident on 1st, 2nd diffraction gratings 2, 3.

IPC: H01L21/306
Filed: 1987-01-29
Abstract: PURPOSE:To obtain a uniform high-flatness surface within the surface of a wafer by a method wherein the upper part of one main surface, whereon an Si oxide film is partially formed, of the wafer is brought into contact to an abrasive liquid consisting of an amino group-containing compound, parts only, at which Si is exposed, of the surface are polished and the Si oxide film is removed. CONSTITUTION:Roughnesses 2 are formed on the surface of a semiconductor wafer 1. An Si oxide film 3 is formed on the peripheral parts of the surface of such the semiconductor wafer 1 by an oxide film forming method, such as a CVD method, and a photo etching technique. Then, after this wafer 1 is polished with an abrasive liquid containing an amino group-containing compound, the film 3 is removed by dry etching or wet etching. In such a way, a flattening of the surface of the semiconductor wafer is contrived. Thereby, as a high flatness can be obtained over the whole surface of the wafer, the manufacturing yield of a VLSI device, whose fine formation and high integration are making progress, can be improved.

Abstract: PURPOSE:To improve the tact time of devices by not only improving the yield but also facilitating the method of temperature detection by a method wherein an infrared ray source is adopted for the heat source. CONSTITUTION:Solar cell elements 5-5<n> are connected in series and loaded on a substrate 6, and further a resin sheet is superposed; then, they are put on stoppers 10 and 10' of the lower mold 2. Next, the upper mold 1 with a diaphragm 3 made of soft heat- insulating rubber installed hermetically is assembled airtightly. Vacuum exhaust is started by means of vacuum exhaust pipes 8 and 9 at the same time. A glass plate 7 of high photo permeability is mounted on the most part of the bottom of the lower mold 2.

At the same time, the vacuum degree of the upper mold 1 and the lower mold 2 is adjusted to about 1Torr or less by means of the vacuum exhaust pipes 8 and 9. When this fusion temperature amounts to a fixed temperature, release of the vacuum pressure of the upper mold to the atmospheric pressure leads the diaphragm 3 to desent as shown by the one-dot chain line of 3'; thus, the solar cell elements 5, 5'-5<n> can be sealed by adhesion to the substrate 6 with the fusion of the resin sheet 4.
