Title: Formation of bump electrode
Inventor: TSUDA AKIHITO
IPC: H01L21/60
Filed: 1988-03-24
Abstract: PURPOSE:To form a bump electrode of a trapezoidal or rectangular parallelepiped shape and to provide sufficient adhering strength by forming metal to become the electrode wholly or partly, and then selectively etching the metal to form the electrode. CONSTITUTION:An insulating film 2 is formed on a semiconductor substrate 1, necessary metal wirings 4 are further formed, and a barrier film 5 is formed on a whole surface of the external connection electrode opened partly at a protective film 3. Then, a bump metal 8 is formed in a necessary thickness on the film 5. Thereafter, photoresist is formed in a necessary shape by a conventional method on the layer 8. Subsequently, with the photoresist pattern 9 as a mask the lower layer 8 is selectively etched. In case of using chemicals, the bump of a trapezoidal shape is formed, while in case of using dry etching, it is anisotropically etched to form a vertical bump having a vertical wall face.

IPC: B21F19/00
Filed: 1978-06-09
Abstract: PURPOSE: To obtain a processing degree necessary for metallic bond by diffusion annealing without the need for annealing on the way by using a fixed full angle of die when drawing clad strand with covering material of a higher deforming resistance than that of core material.  
     CONSTITUTION: When obtaining a metallic bond between core material and covering material by applying one or more repeated cycle of cold drawing and diffusion annealing on a clad strand consisting of a metal core and a covering metal of a higher deforming resistance than that of the core metal, or preferably a clad strand consisting of an Al or Al alloy core and a copper or copper alloy covering, the cold drawing of the strand is made by using a die of ful angle 2α of 20 to 45° until the metallic bond is obtained. This method enables one to draw the strand without failure and also to obtain sufficient metallic bond between them by annealing when obtaining soft core type clad wires.

Filed: 1986-03-27
Abstract: PURPOSE:To improve machining efficiency by providing a valve continuity operation mechanism for making a non-return valve continuous and a pressure change mechanism for changing a pressure medium to be fed to the non-return valve, to a predetermined level, and applying construction for enabling the change of a chuck holding force in a machining process. CONSTITUTION:Oil is fed from a high pressure hydraulic source 1, thereby changing over a changeover valve 3c for high and low pressures to the high pressure side, changing over a changeover valve 5c for opening and closing a chuck to the outer chucking side and causing a chuck 'G' to catch a workpiece. And after composite machining, the changeover valve 3c is changed over to the low pressure side and a changeover valve 9a for the pilot of a valve continuity operation mechanism 9 is operated, thereby actuating a sub- plunger mechanism 9d. In this state, said changeover valve 9a is operated after a predetermined time for cutting off oil, thereby returning a sub-plunger 9d1 to an original position and sealing low pressure oil in a cylinder chamber 7d. Consequently, the holding force of the chuck 'G' becomes weak and high precision machining can be ensured.
