Abstract
A method for attaching a conductive particle to the apex of a probe tip comprises the steps of: moving the apex of a probe tip close to a conductive particle and applying a bias voltage between the probe tip and the conductive particle so that the conductive particle can permanently attach to the apex. The method uses only a bias voltage to transfer and attach conductive particles to the apex of a probe tip, and no surface treatment of the probe tip is required.
