Title: Etching of plating electrode film for bump electrode
Inventor: MARUYAMA SUMIAKI
IPC: C23F1/16
Filed: 1989-11-13
Abstract: PURPOSE:To remove a plating electrode film for each bump electrode easily by etching each plating electrode film by the use of an acid etching solution to which a small amount of a surface active agent is added and then, removing an etching residuum which is attached again to the surface of a wafer after cleaning the above wafer. CONSTITUTION:A plating electrode film 5 is removed from a wafer 10 by etching in such a way as to allow its etching to use an acid etching solution to which a surface active agent is added. After that, etching residua that are attached again to the surface of the wafer 10 are removed by cleaning. As a result, small flakes 5c of each electrode film 5 which are peeled off from the wafer 10 during its etching process are wrapped by the surface active agent and even though the small flakes are attached again to the surface of the wafer 10, the flakes are removed easily by the next cleaning process. Similarly, small flakes 5a of each plating electrode film 5 that are floating in an etching solution do not attach to the surface of the wafer 10 very much. Each plating electrode film 5 is thus removed easily from the wafer.

Abstract: PURPOSE: To obtain a probe device in which irregularity in the contact resistance of respective probe needles is eliminated and which can perform a precise measurement by a method wherein derivation positions from an insulating member of the probe needles are arranged in a zigzag shape. CONSTITUTION: Many fine probe needles 10a to 10c for a probe needle 10 are isolated from each other, and they are fixed to an insulating member 11. Free end parts of the needles 10a to 10c which have been derived from the member 11 are bent in the same direction, and their edges are brought into elastic contact with an electrode 3b for an object to be measured in a zigzag shape so as to be connected electrically. At this time, derivation positions from the member 11 of the needles 10a to 10c are arranged in a zigzag shape so as to correspond to the zigzag arrangement of the free end parts of the probe 10. In addition, the derivation face from the probe 10 of the member 11 is tilted in such a way that distances up to base parts from the free end parts of the needles 10a to 10c become equal. Thereby, lengths of the needles 10a to 10c are resembles closely. When the needle 10 is pressed to the electrode 3b down to a prescribed depth so as to come into contact surely, deformation amounts of the needles 10a to 10c are resembled closely, and also contact pressures are resembled closely. Consequently, it is possible to avoid a measuring defect based on irregularity in a contact resistance, and a precise measurement can be performed.
