摘要： A semiconductor device test probe having a tip portion for being urged against an electrode pad of an integrated semiconductor device to establish an electrical contact against the electrode pad for testing functions of the semiconductor device. The spherical tip portion has a radius of curvature r expressed by 9t≦r≦35t, where r is the radius of curvature of the spherical surface and t is the thickness of the electrode pad. The tip portion may have a first curved surface substantially positioned in the direction of slippage of the probe when the probe is urged against the electrode pad and slipped relative to the electrode pad and a second curved surface opposite to the first curved surface. The first curved surface has a radius of curvature of from 7 μm to 30 μm and larger than that of the second curved surface. The test probe may be manufactured by a method comprising the steps of roughing the tip portion of the curved surface by abrasing by means of electrolyte abrasion or abrasing particles to form a symmetrical spherical curved surface, and finishing the tip portion by sliding it on an abrasive member comprising an elastically deformable thick film fixed to a substrate and having abrasive particles therein or thereon directly or through a metallic film.

摘要： Multiple probe needles are arranged to be brought into contact with one electrode pad with a probe card, the multiple probe needles are connected in parallel with the same potential, and configured so that the amount of current flowing through the probe needles is at least halved, thereby decreasing generation of heat from Joule heat, and preventing melting of aluminum of which the electrode pads are composed. Consequently, a probe card can be provided wherein adhesion of molten material to the probe needles is suppressed, and wherein increased contact resistance due to oxidization of the material which has melted and adhered is prevented.
