发明名称 Member for removing foreign matter adhering to probe tip and method of manufacturing the probe tip, method of cleaning foreign matter adhering to probe tip, probe, and probing apparatus
摘要 The present invention provides a member for removing foreign matter adhering to the spherical tip portion of a test probe which is put into contact with the bonding pads of a semiconductor chip to test the action of the semiconductor chip. The member includes four essential layers of a base plate, a first elastic member on the base plate and flexibly deformable upon contact of the probe, specifically, a predetermined Young's modulus, a second elastic member on the first elastic member and having a tensile strength and a thickness responding to contact stress produced by the contact of the probe, and an abrasive layer on the second elastic member and made of hard particles and a binding material in a volume ratio providing a smooth sliding action of the probe and producing a high abrasive efficiency to any adhering foreign matter. The removing member can smoothly slide the probe to effectively remove the foreign matter adhering to the probe tip.
