Title: Semiconductor device
Inventor: YAMADA HIROSAKU
IPC: H01L21/3205
Filed: 1984-12-21
Abstract: PURPOSE:To improve the tight adhesive strength and the electric contacting property of a high melting point metal by a method wherein, in the wiring layer of a silicon semiconductor device, an oxide-growing metal layer having the standard free energy smaller than that of SiO2 is provided on the base of the high melting point metal layer. CONSTITUTION:After a field oxide film 2 is formed on a silicon substrate 1, an N<+> layer 4 is formed by implanting arsenic 3. Then, after SiO25 is covered on the whole surface, a layer 6 of 10-500Angstrom  in thickness consisting of at least a kind of berylium, magnesium, titanium, zirconium and halfnium is formed on the whole surface as the first metal layer. Also, the second layer 7 consisting of at least a kind of molybdenum, tungsten niobium and tantalum is formed thereon. As a result, the natural oxide film on a silicon semiconductor is reduced to the first layer metal, and a part of the surface of the SiO2 is also reduced, thereby enabling to obtain the excellent tight adhesive strength and the electric contacting property for a high melting point metal.

Title: Alignment mark and liquid crystal element using the same and its production
Inventor: TAKANO KATSUHIKO
IPC: G03F1/42
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to decide whether alignment is accepted or rejected by visual observation of superposed alignment marks or the observation to the extent of microscopic observation by combining a frame shape of a width equal to the standard value of alignment and a shape which is included in this frame and partially abuts on the inner side of the frame. SOLUTION: The one mark 1 of the alignment marks 1, 2 used at the time of aligning plural plane patterns is formed to a rectangular (for example, square) bored frame shape and the other mark 2 is formed to a circular (for example, complete round) shape. If the mark 2 on the side where both marks 1, 2 are included so as not to overlap on each other exists on the inner side of the mark 1, the alignment is accepted in the standard (a). The width t1 of the frame of the one mark 1 is formed equal to the standard value of the alignment. Then, if the mark 2 deviates within the standard, this mark does not protrude outside the frame of the mark 1 and the alignment is accepted (b). If the marks deviated from the standard value, the marks protrude to the outside of the frame and the alignment is rejected (c, d).

IPC: H04N1/405
Filed: 1994-11-01
Abstract: PURPOSE: To change linearly the density to be printed based on a multi-valued image signal from a low density area up to a high density area with a comparatively simple adjustment. CONSTITUTION: A pulse width modulation section 32 divides a pulse width of one picture element into 1/8 equally corresponding to each gradation and applies pulse width modulation to data based on the gradation of the multi- valued image data stored in a page memory 31. A power modulation section 33 modulates the power of the pulse signal with a pulse width corresponding to each gradation so that the print density changes linearly from a low density area up to a high density area based on the gradation of the multi-valued image data. Thus, the pulse signal with different pulse width and power corresponding to each gradation is obtained and the print density changes linearly from a low density area up to a high density area by using the pulse signal.

IPC: E01C9/08
Filed: 1994-11-02
Abstract: PURPOSE: To reduce displacement to load by forming a specified inclined grade in the direction of a kerb stepped section toward the downward direction of a lateral reinforcing rib mounted on the rear of a land slope by the lateral reinforcing rib. CONSTITUTION: Auxiliary ribs drooped and formed on the rear side of an injection-molded land slope 1 consist of vertial reinforcing ribs 13 parallel in the direction of projecting width (a) and lateral reinforcing ribs 12 being crossed with the ribs 13 and parallel with the longitudinal direction (b), and the lateral ribs 12 form an inclined grade of approximately 6 deg. in the direction of a kerb stepped section B toward lower sections. When such a land slope 1 is abutted and installed to the kerb stepped section B, the lateral auxiliary ribs 12 forming the inclined grade θ-2 of approximately 6 deg. are directed at a right angle θ-3 in the direction that load such as a car is applied because the drainage grade θ-1 of a kerb A is approximately 6 deg., thus maximizing withstand load strength.

Title: Semiconductor pressure sensor
Inventor: KONDO YUJI
IPC: G01L9/04
Filed: 1988-10-25
Abstract: PURPOSE:To improve the accuracy and reliability of a pressure sensor by preventing a leakage current from being produced by fixing a potential applied to a PN junction formed between an active layer and a resistance area. CONSTITUTION:Gauge resistors 4 (R1-R4) constitute a wheatstone bridge 21 which is then connected between a power supply VDD and the ground, and a protective diode D1 formed of an N type epitaxial layer 2 and a p type substrate 1 is provided in parallel to the bridge 21. A circuit formationsection of the epitaxial layer 2 is fixed to a power supply voltage through an epitaxial layer fixing area 5 with the substrate 1 fixed to a ground level. Accordingly, the potential at a resistor 4 is the same level as VDD at maximum, so that for a relation between the potential at the resistor 4 and at the epitaxial layer 7 of the circuit formation section, it is always kept unchanged or the epitaxial layer 7 is higher. Thus, a PN junction between the resistor 4 and the epitaxial layer 7 is always back-biassed without permitting any current to flow therethrough.

Title: Solid state image pick-up device
Inventor: SATO SHIGERU
IPC: H04N5/335
Filed: 1984-12-21
Abstract: PURPOSE:To improve the quality of image pick-up picture while reducing the incoming false signals due to multiple reflection by a method wherein layers comprising sensitive emulsion etc. with less reflecting power are arranged on the regions excluding sensitive parts above a semiconductor substrate. CONSTITUTION:Layers 14 comprising sensitive emulsion with less reflecting power are arranged on the regions excluding sensitive parts 2 above a semiconductor substrate 1. The layers 14 are provided with the property of selecting colors by changing the wave length of light to be sensitized making it feasible to reduce the reflecting power by sensitizing the upper regions of substrate 1 excluding the sensitive parts 2 to e.g. black color. Consequently the light 13 transmitting a cap 11 being mostly absobed into the layers 14 may reduce the amount to be insulated even in case of multiple reflection. Through these procedures, the amount of photosignals to reach the sensitive parts 2 may be extremely reduced eliminating any flare phenomenon to produce a solid image pick-up device with excellent quality of image pick-up picture.
