IPC: H01L21/60
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a stable ball limiting metal(BLM) film having almost no diffusion reaction when heat treated after a BLM film formation step. SOLUTION: A manufacturing step includes a step Q1 for patterning a first passivation film, a step Q2 for patterning a BLM film, a step Q3 for patterning a second passivation film, a step Q4 for hardening the second passivation film, and at the same time annealing the BLM film, a step Q5 for patterning a bump metallic film, and a step Q6 for putting the bump forming metallic film in a wet-back treatment. By the step Q4 for annealing the BLM film while the passivation film is annealed, the BLM film is increased in its density, and heat diffusion of copper in the BLM film or lead in the metallic bump in the wet- back heat treatment step can be reduced. As a result, the bump can be formed without a break caused by the decrease in strength of the BLM film.

Title: Malfunction detector for steam pipe
Inventor: OSUMI TAKAYOSHI
IPC: F16T1/48
Filed: 1989-06-14
Abstract: PURPOSE:To prevent such a possibility that drain continues to flow into a steam service apparatus and a water hammer is produced from occurring by installing a tank in a drain outlet installed in a steam separator, connecting an air vent valve to an upper part of the tank, and providing a pressure detecting means which detects the opening or closing of this valve. CONSTITUTION:Drain separated by a steam separator 4 flows into a tank 5, and air in the tank replaced with the drain and reevaporated steam of partial drain are exhausted to the outside of the tank 5 from an air vent valve 10 installed on the tank 5, so that the drain is collected in the tank 5. Then they are reached to the air vent valve 10 filled up the inside of the tank with the drain, the valve is opened, coming to closed state, going up to pressure almost equal to the inside of the steam pipe 3. This pressure rise is detected by a pressure sensor 9, finding a fact that whether the inside of the tank 5 is filled up with the drain or not, and time of up to this fillingness is measured whereby the drain quantity is measured. With the drain quantity measured like this, whether the steam pipe 3 is a steady state or an abnormal state can be detected.

Title: Electric discharge machining electrode
Inventor: MORI NAOTAKE
IPC: B23H1/06
Filed: 1984-07-24
Abstract: PURPOSE:To eliminate an increase in inta-electrode static capacity for forming precisely machined surface, by fusing or mixing such substance as inorganic compound etc. having high electric resistance in a metal with low melting point such as zinc or in an alloy principally consisting of such metals. CONSTITUTION:The captioned electrode is set up in such a way that discharge current at one place is limited even if electric discharge takes place due to electric charge cumulated in a capacitor formed between electrodes, because raw materials themselves forming the capacitor possess electric resistance, consequently other discharge points on mutually facing surfaces of electrodes 2 and 9 can also generate electric discharge so that a distributed constant circuit may be formed, duly enabling a plurality of discharge to be generated in the surface of the same electrodes 2 and 9. Therefore, a machined surface can have much more delicate surface roughness in the case of zinc and silcon electrodes, zinc and zinc oxide electrode etc. Then in the case of copper electrodes with the same amount of supplied energy, duly giving better machined surface although the area of the electrode is larger. Furthermore, low melting point alloy is less liable to generate bridge, otherwise being dispersed along the total discharge area, resulting in small discharge even though the existend static capacity is large.
