Title: Fixing method for semiconductor pellet
Inventor: SEKIDA KOICHI
IPC: H01L21/52
Filed: 1987-03-10
Abstract: PURPOSE:To improve adhesion strength, electric conductivity heat conductivity, and heat-resisting performance and to enable automation in bonding, by forming a metallic thin film on a rear of a semiconductor substrate and next covering the main surface with a protective film and forming a plating layer of a gold group alloy and cutting this substrate into pellets and welding their pellets on a supporting board. CONSTITUTION:A metallic thin film 2 is formed to serve as a base of alloy plating on a rear of a wafer 1 with an element active region formed on a main surface thereof. This metallic thin film 2 is made to be a three-layer metallic film like Ti-Pt-Au or a two layer metallic film like Cr-Au. In succession, a main surface of the wafer 1 is coated with a protective film 3 made of a photoresist or the like and the wafer 1 is soaked into an alloy plating bath to perform electrolytic plating, so that a gold group eutectic crystal alloy plating layer 4 is formed on a surface of the metallic thin film 2 which is formed on the rear of the wafer 1. The protective film 3 on the main surface of the wafer 1 is removed and the wafer 1 is cut into individual pellets 5. Thereafter, the respective pellets 5 are mounted on a supporting board 6 such as a lead frame or a ceramic substrate and heated. Thus, the eutectic crystal alloy plating layer 4 is fused and the pellets 5 are welded on the supporting board 6, so that uniform and solid adhesion is obtained.

Inventor: KURIMOTO ARIYASU
IPC: B24B5/36
Filed: 1985-03-19
Abstract: PURPOSE:To permit the mirror-surface polishing with high precision by shifting the outer peripheral surface of a rope, etc. which passes through a metal pipe, along the inner surface of the metal pipe, and allowing the etching agent containing abrasive grains mixed to pass in slidable contatc with the inner surface of the metal pipe. CONSTITUTION:The cable article 3 such as rope is inserted inside a long metal pipe 1 having a small diameter. Onto said cable article 3, slidable contact bodies 4 impregnated with etching agent containing abrasive grains mixed are installed at a cetrain intervals in the longitudinal direction. When the cable article 3 is pulled and shifted in the longitudinal direction into the metal pipe by allowing the slidable contact body 4 to be impregnated with etching agent, the inner peripheral surface is polished by allowing the outer peripheral surface of the slidable contact body 4 to pass from one edge to the other edge of the metal pipe 1, in slidable contact with the inner peripheral surface of the metal pipe 1. It is necessary for the slidable contact body 4 in stable state to revolve the metal pipe 1 so as to contact with the polished surface, and the polishing to the max. roughness of 0.5 or less is performed over the whole length of the inner peripheral surface of the metal pipe 1 by carrying-out the polishing work for a proper time.

SOLUTION: A temporarily fastening member formed of resinous temporarily fastening members 10A and 10A to temporarily fasten a bolt 2 having a flange, is arranged in a part 1. The temporarily fastening member is a member molded so as to become a taper shape whose width gradually becomes narrower than the side of an opening part into which the bolt 2 having a flange and an impact wrench 3 are inserted. In the temporarily fastening member, gripping parts 12 to grip a flange part 22 of the bolt 2 having a flange are formed on its tip, that is, in an end part which is most distant from the opening part and whose width between the temporarily fastening members 10A and 10B becomes narrow. The gripping parts 12 are U-shaped gripping parts to sandwich an upper surface and an under surface of the flange part 22.  When both ends of the flange part 22 of the bolt 2 having a flange are gripped by the gripping parts 12 of these temporarily fastening members 10A and 10B, the bolt 2 is temporarily fastened to the part 1.

Abstract: PURPOSE: To easily separate foreign matters from an inlet port sucking the foreign matters by providing a bypass inlet port separately from the inlet port and providing a vacuum control valve opened when negative pressure over a prescribed level is applied to an inlet pipeline side in a bypass pipeline. CONSTITUTION: When a pump 5 is operated, hot water 4 in a bathtub 1 is sucked from the inlet port 3, and fetched in the pump 5 via the inlet pipeline 17. The hot water 4 is sent to a jet device 21 via a jet pipeline 19, and discharged from the jet port 7 of an orifice in the inside. At this time, when the foreign matters such as the hand/foot or hair of a person. etc., is sucked accidentally from the inlet port 3, pressure in the rear side housing 33 of the inlet port 3 shows high negative pressure. In other words, the inlet pipeline 17 side, a part of which is constituted of the rear side housing 33 shows the high negative pressure.  When such negative pressure exceeds a fixed level, the negative pressure in the inlet port 3 is reduced by opening by deflecting the coil spring 49 of the vacuum control valve 45, which enables the foreign matters sucked in the inlet port 3 to easily be separated.
