Abstract: PURPOSE:To provide a highly reliable semiconductor device having improved adhesion of the barrier metal on an insulating film. CONSTITUTION:A Ti-Si film 13, having the compositional ratio of TiSi2, is formed on the upper surface of the BPSG film 12 formed on the surface of a silicon substrate 11, a TiN/Ti barrier metal film 14, on which a Ti film and a TiN film are formed on the upper surface of the Ti-Si film 13, is laminated and an electrode wiring 17 is provided on the barrier metal film 14. As a result, the barrier metal film 14 is closely adhered to the BPSG film 12 through the intermediary of the Ti-Si film 13, and the barrier metal film 14 is prevented from adhering to the BPSG film directly. As a result, the structure in the vicinity of the interface of the BPSG film 12 is prevented from becoming embrittled by the Ti of the metal element constituting the barrier metal film 14 even when a heat treatment is conducted to reduce the contact exfoliation can be eliminated.

Title: Scroll type compressor
Inventor: OZU MASAO
IPC: F04C23/00
Filed: 1987-04-27
Abstract: PURPOSE:To lessen a compression load by forming a high pressure chamber above a stationary blade and providing the stationary blade in such a way as to be vertically movable sliding on a division separating the high pressure chamber while airtightness is being maintained. CONSTITUTION:A seal member 21 is provided on the external surface of a projection erected on the upper part of a stationary blade 15 and a high pressure chamber 23 is formed within a discharge muffler 18.

Title: Method for carrying and positioning lead frame
Inventor: SHIMANUKI MAKOTO
IPC: H01L21/50
Filed: 1983-06-06
Abstract: PURPOSE:To enable to carry and position the lead frame at a high speed and thus contrive to speed up the assembly of the semiconductor device by a method wherein the lead frame is carried by being pinched with an upper and lower pair of feeding roller means. CONSTITUTION:Said roller means 6 and 7 are separated above and below the lead frame 1. Next, the feeding roller means 6 is lowered, and the feeding roller means 7 is raised, thus both coming into contact with the lead frame 1, which frame is then pinched under some pressure from above and below. Successively, when the roller means 7 is driven by rotation, the lead frame is carried as an arrow to the longitudinal direction by frictional force. On feeding the lead frame 1 to a fixed distance, the rotational drive of the roller means 7 is stopped, the roller means 6 and 7 being raised and lowered to feedback, and at the same time a positioning pin 4 thus being raised, resulting in positioning by insertion to a positioning hole 2.

Title: Manufacture of semiconductor device
Inventor: YANAI MASAHARU
IPC: H01L21/28
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device manufacturing method by which a semiconductor device having a barrier metallic layer can be manufactured, and the occurrence of such a case is prevented that the barrier metallic layer is not completely etched off due to TiF and TiO produced on the surface of the metallic layer, and short circuits occur in metallic wiring due to the left part of the metallic layer. SOLUTION: The barrier metallic layer 14 on a semiconductor substrate 10 is irradiated with plasma 40 of an N2 gas and, at the same time, the substrate 10 is heated with a heater 50. Since the TiF and TiO in an affected section 20 produced on the surface of the metallic layer 14 are returned to TiN by the plasma 40, the hindrance to the etching of the metallic layer 14 are removed. Therefore, the metallic layer 14 is completely etched off, and the occurrence of short circuits in metallic wiring can be prevented.

Title: Catalyst body for purifying gas
Inventor: KIMURA KUNIO
IPC: B01D53/94
Filed: 1980-07-24
Abstract: PURPOSE:To obtain catalysts which are excellent in heat resistance and have a long life by preventing the sintering of metallic oxides, by mixing a proper amount of titanium oxide into lime aluminate and transition metallic oxides. CONSTITUTION:This is a catalyst for purifying waste gases which consists essentially of lime aluminate, transition metallic oxides, and titanium oxide. The titanium oxide content in this catalyst is 5-50wt%. The lime aluminate is usually represented by alumina cement which is expressed as mAl2O3.n CaO, and as the Al2O3 content becomes higher, the heat resisting property becomes more excellent and the mixed iron oxide exhibits stronger cocatalystic effect. As for the TiO2, anatase type is more desirable than rutile type because of its heat stability. Moreover composite oxide, such as TiO2-Al2O3, TiO2-ZrO3, etc., can also be used as the TiO2 source. When the TiO2 content is less than the lower limit, its adding effect cannot be expected, and, in contrary, when more than the upper limit, the other essential elements become less and, as a result, the binding force becomes weaker and the catalyst cannot stand when it is used. The above-mentioned essential elements are mixed with water whose amount is just enough for forming, and the mixture is solidified after forming and aging.

Abstract: PURPOSE: To make small the size and light the weight for the optical head, by inserting the relay lens between the objective lens and the reflection mirror and between the reflection mirror and the light polarizer, in the optical head of the optical type information recording and reproduction unit.  
     CONSTITUTION: The relay lenses 13, 14 are inserted respectively between the objective lens 11 and the reflection mirror 12 and between the reflection mirror 12 and the light polarizer 13. Taking the focus of the lenses 13, 14 as f, since the distance between the light source focus P 1  of the objective lens 11 and the relay lens 13, distance between the relay lenses 13 and 14 and the reflection mirror 12, and the distance between the relay lens 14 and the light deflector 3, are taken all f, the deflection point P 2  of the light deflector 3 is conjugate as the light source focus P 1  of the objective lens 11, to avoid the light axis transversal shift of the reflection light 6 based on the turning of the deflector 3. Thus, the optical head can be made small in size and light in the weight.
