Patent JP-2000106384-A (JP)
Title: Manufacture of bonding wire
Inventor: MITSUNARI NAOHITO
IPC: H01B13/00
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To manufacture a wire whose surface condition is stable and provide a semiconductor having excellent reliability, by purifying the surface of the wire after annealing, and cleaning the surface afterwards. SOLUTION: In this method, gold or ingot of gold alloy is used as material. The method comprises a step of wiredrawing the material to manufacture a wire, a step of annealing the wire, and a step of cleaning the surface of the wire to obtain a bonding wire. For example, by using ingot of cold having a purity of 5N as material, a wire having the diameter of 30 μm is finally obtained. The wire is annealed at a temperature of 500 deg.C, then the wire is subjected to any of an argon hydrogen plasma treatment or alkaline electrolytic degreasing treatment in low vacuum. Thereafter, the surface of the wire is cleaned. The reason why the plasma treatment or alkaline electrolytic degreasing treatment is carried out is that a hydrophobic modified layer becomes hydrophilic.  And, it is preferable to previously determine the most favorable conditions for the plasma treatment or the alkaline electrolytic degreasing treatment. Because the conditions for the plasma treatment or the alkaline electrolytic degreasing treatment differ depending on the quantity of modified layer deposited to the wire or a lubricating oil used for a wiredrawing process, preliminary optical condition is preferably determined.

IPC: B60R1/06
Filed: 1991-09-27
Abstract: PURPOSE:To prevent a mirror from the occurrence of blurring due to the vibration of a car by smoothly executing the inclined motion of an electrically operated mirror in horizontal and vertical directions. CONSTITUTION:A mirror holder 6 formed of a hemisphere cup-shaped body is held in a case 1 having a similar hemisphere cup-shaped concave part in the state of coming into sliding contact with each other, and incliningly acting force is given to the mirror holder 6 through a driving means including motors 21.31 arranged in the mirror holder 6 in the state of coming into contact with it to incliningly move the mirror body 6 itself and a mirror fixed to it.
