Title: Enhancement of close adhesiveness of metal in semiconductor device manufacture process
Inventor: KONDO MASAHARU
IPC: H01L21/3065
Filed: 1985-07-03
Abstract: PURPOSE:To enhance the close adhesiveness of metal by a method wherein oxygen plasma processing is performed before the evaporation of metal so as to remove the organic contaminant which is remaining in a wafer or naturally adhered on it. CONSTITUTION:In the process of the semiconductor device manufacture, organic contaminant that remains on the wafer or is naturally adhered on it is removed by means of oxygen at the period of generation in the production and decomposition of ozones in oxygen plasma before evaporation of metal to enhance the close adhesiveness of metal. When oxygen plasma processing is performed, clearly organic contaminant is reduced, providing a cleaned surface of a wafer. Failure in adhesiveness such as pealing does not appear on the samples that have undergone the oxygen plasma processing.

Title: Press mold holding equipment
Inventor: SATOU JIYUNZOU
IPC: B21D37/14
Filed: 1980-10-22
Abstract: PURPOSE: To sharply improve the durability of the titled equipment, by dividing the mold holding member into two parts; a holding member which is fitted to the mold at one side and another holding member which can be fitted to, and removed from this holding member, and removing only the latter holding member when press work is performed.  
     CONSTITUTION: When press works are performed, only an upper holding member 12 is removed and a slide 5 is moved upward and downward to perform press works. When the slide 5 containing a top part 2 is lowered to the bottom dead center at the time of press works, a lower holding member 11 never contracts after the upper holding member 12 is removed, and, therefore, the durability is sharply improved and scatterings of the holding member due to cracks caused by secular changes are also prevented. Moreover, when the press mold is not used for a long time, the upper holding member 12 is put on the lower holding member 11 by lifting up the slide 5, and then, the top part 2 is removed from the slide 5 and placed on the holding member 10. Thus, the press mold is kept for a long time while the top part 2 is lifted up for a fixed clearance from th bottom part 1.

Abstract: PURPOSE:To improve the efficiency of inspection by generating >=2 light cutting lines on the surface of a parts to be inspected at the same time without moving a measurement table. CONSTITUTION:This inspecting instrument consists of light projecting devices 4a-4d which irradiate the parts 5 to be inspected on a substrate with projection light and generate light cutting lines on the surface of the parts 5, a camera 3 which converts the light cutting lines into light cutting image photoelectrically, etc. When the position shift of the parts is inspected, an arithmetic controller 7 operates the plural light projecting devices 4a-4d to project plate type light at a time. Consequently, the plural light cutting lines 6a-6c crossing the plate type light crosses are formed at different positions on the surface of the parts at the same time. The respective lines 6a-6c are picked up by the camera 3 to generate their beam images, whose video signals are inputted to the device 7 to perform arithmetic and processing regarding the inspection of the position shift. Consequently, the object 2 of inspection need not be moved by the measurement stage 1 so as to generate the plural light cutting lines, thereby improving the inspection efficiency.

Title: Method for treatment of peroxide-containing aqueous solution
Inventor: HINUMA HITOSHI
IPC: B01J19/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To degradation treat efficiently sterilizer waste-water containing peroxide with a simple operation by a method wherein a treating liquid is passed in a flow type reaction device in which a platinum-supporting catalyst is filled so that a space velocity being a ratio of a feed volume velocity of treating liquid to a catalyst layer volume becomes a specific value or under. SOLUTION: A treating object is aqueous solution containing at least one kind of hydrogen peroxide and peracetic acid. Then, after filling a platinum- carrying catalyst 2 in a flow type reactor, the treating liquid is passed in the apparatus by feeding the treating liquid into the apparatus. Thereby, the treating liquid is brought in contact with the catalyst 2. By this treatment, the hydrogen peroxide and the peracetic acid are considered to generate oxygen by respectively generating reactions and be degradated. As the flow type reactor, a fixed bed type catalyst reaction device generally suffices only by using that, and it is preferable to make the solution to be treated pass through a column 1 as an upward flow. In this case, a space velocity F of treating liquid to a catalyst layer volume W is 10 h<-1> or under.
