Title: Gas sensor
Inventor: KODA HIROSHI
IPC: G01N27/04
Filed: 1991-02-28
Abstract: PURPOSE:To shorten initial misoperating time of a gas sensor. CONSTITUTION:Cu is added to a metal oxide semiconductor film gas sensor such as SnO2. A preferred amount of Cu to be added is 0.2 to 0.5% by an atomic ratio such as Cu/Sn, and the optimum value is 0.3%. Addition of Cu increases a resistance value of the metal oxide semiconductor film, whereas addition of an excessive amount is not preferable. An effect for shortening initial misoperating time due to Cu is especially remarkable for a thin-film-type gas sensor.

IPC: H01L29/866
Filed: 1988-03-14
Abstract: PURPOSE:To eliminate an increase in a reverse leakage current from a reverse-biased junction when a voltage is applied at a high temperature and a short-circuit due to a solder material by a method wherein the side surfaces of a basic substrate are respectively constituted of slanted two mesa surfaces, whose areas respectively become small from intermediate high- concentration layers toward-low concentration layers on the sides of the main surfaces of the element. CONSTITUTION:A mesa type semiconductor basic substrate 10 is constituted by a method wherein N-type semiconductor layers 11N and 12N and P<+> semiconductor layers 11P and 12P of an impurity concentration higher than those of these layers 11N and 12N are respectively laminated, the main surfaces, which face the side of a P<+> layer, of first and second semiconductor substrates 11 and 12 formed with a P<+>-N junction J1 or J2 are bonded together by adhesion and the substrates 11 and 12 are formed integrally with each other on an adhesive surface 18. Moreover, the side surfaces of the basic substrate respectively consist of mesa surfaces 11S and 12S, whose surface areas respectively become small from the intermediate layers 11P and 12P toward the layers 11N and 12N on the sides of the main surfaces of the basic substrate and which respectively have a positive mesa angle theta1 or theta2. When a voltage is applied to the sides of both main surfaces of this basic substrate, the field strengths in the vicinities of the junctions on the mesa surfaces become smaller than the field strength on a junction in the interior of a chip and even though a voltage is applied at a high temperature, a reverse leakage current is small and is constant and a stable constant-voltage characteristic is obtained.

Title: Patterning process for multilayered metallic layer by dry etching
Inventor: SAKOTA YUJI
IPC: H01L21/302
Filed: 1988-03-14
Abstract: PURPOSE:To keep the film surface clean while enabling the patterning process to be performed with high precision by a method wherein a material as an etching mask provided with the excellent reactive ion etching property and the inferior sputter etching property is formed on a second layer. CONSTITUTION:A three layered metals successively formed on a Ti film 2, a Pt film 3 and an Au film 4 are prepared on a substrate 1. First, a Ti etching mask 35 provided with the excellent reactive ion etching property as well as the inferior sputtering property is formed on the second layer i.e. the Au film 4 in excellent sputter etching property. Second, the second layer (Au film 4 and Pt film 3) is etched away by Ar sputter etching process meeting the specified requirements. At this time, even if the Au film 4 and the Pt film 3 are relatively thick and it takes a long time to do sputter etching, the etching mask 35 is hardly provided with the Ar sputter etching property. Consequently, no change of properties, etc., occurs in the junction surface of the Au film 4 and the etching mask 35 so that the etching mask 35 may be released easily later enabling the surface to be kept clean.

Title: Extruded building material made of lightweight cement
Inventor: KATAHIRA FUJIO
IPC: B28B3/20
Filed: 1991-03-25
Abstract: PURPOSE:To obtain the extruded lightweight cement building material having excellent surface smoothness by incorporating a specific ratio of vermiculite adjusted to a specific grain size distribution as lightweight aggregate into this material. CONSTITUTION:The extruded building material made of the lightweight cement is obtd. by adding proper volume of water to a material, which is obtd. by compounding an admixture with ceramic powder consisting of a hydraulic binder and aggregate, then subjecting this mixture to kneading, extrusion molding and curing. The ceramic powder contg. 5 to 30% vermiculite adjusted to the grain size distribution of >=20wt.% of <=50mu grain size and <=10% of >=300mu grain size is used at this time. The surface smoothness of the vermiculite to be used is insufficient in the case of >=10% of 300mu grain size. The effect of improving extrudability is low and the surface smoothness is not improved in the case of <20% of <=50mu grain size. The effect of improving the smoothness is low if the vermiculite is <=5 pts.wt. in 100 pts. total ceramic powder. The degradation in the strength arising from the decrease of the sp. gr. and the drastic degradation in freezing hazard resistance important as a building material are resulted if the content thereof exceeds 30 pts.
