Title: Formation of wafer bump in semiconductor device
Inventor: YAMANE SHUICHI
IPC: H01L21/321
Filed: 1990-03-19
Abstract: PURPOSE:To prevent the oxidation of an exposed part of a bump metal Cu and to solve the problem that an electrode gap is narrow because of the mushroom shape of a bump by coating the side face of a wafer bump with Pd and by constituting it so that its shape is straight. CONSTITUTION:Cu is grown with the second metal (Pd layer) 52 as the electrode: this Cu bump 58 is matched with the first resist layer in thickness and then plated with the second metal (Au) to form an Au bump 60 into a bump metal. The next step of peeling the second resist layer 56 and of aqua regia etching to etch off Pd as well as Ti brings about a state of Au exposure to peel the first layer resist 48 with the result that Ti of the bump's outermost layer is selectively etched off. The above-mentioned process makes the side face of a Cu bump all coated with Pd. This way prevents oxidation completely and further enables a straight bump shape, thereby narrowing an electrode gap to multiply pins and reduce cost.

Title: Cassette housing
Inventor: NAOI AKIRA
IPC: G11B15/665
Filed: 1979-05-30
Abstract: PURPOSE:To prevent a cassette from spring out of a main body by making damping force operate on the cassette in the process of projection into an insertion opening, by providing a damping piece which controls the projection according to the displacement of a cassette receptacle in ejection. CONSTITUTION:Once a cassette is inserted into a cassette insertion opening, cassette receptacle 4 moves backward together with the cassette and in the process of this movement, projection part B1 is elastically pressed against the side part of the cassette in the beginning. However, as the elastic pressing weakens, depressing action on the cassette disappears finally and at a loading position, cassette is movable into receptacle 4. As receptacle 4 moves forward from the operation posi- tion through ejecting operation, projection part B1 is elastically pressed against the cassette side part for damping and according to the advance of cassette receptacle 4, this damping force increases, so that after cassette receptacle 4 stops, the cassette will stop being partially exposed out of the cassette insertion mouth.

Filed: 1980-05-22
Abstract: PURPOSE:To obtain automatically the optimum exposure by detecting a reflected light from a manuscript and adjusting an aperture of a lens system comparing with the proper exposure settled in the automatic exposure controlling part. CONSTITUTION:After a reflected light from a manuscript 18 was reflected at the first mirror 19, one part of the light is reflected to the upper direction at a half mirror 23. When a light receiving element 24 provided opposedly to a half mirror 23 receives a reflected light from the mirror 23, the output is subjected to photoelectric conversion and after that it is amplified at an amplifying part 30. An automatic exposure controlling part 32, comparing a reflected light from a manuscript 18 with the preset value settled at a proper exposure setting part 33, for example, if smaller than the preset value, through a motor driving part 34 and a driving part 25, makes a central opening part D of a restricting blade larger. In this manner, the reflected light from the manuscript 18 is adjusted momentarily to the optimum value via the second mirror 20 imaged on the photosensitive surface. With such constitution, the optimum exposure is automatically obtained.
