Abstract: Disclosed herein is a method for fabricating a probe needle tip of a probe card, in which, in order to prevent a poor grinding effect caused by irregular removal or flexibility of the photoresists laminated to be high in the course of polishing a first metal loaded into the opening of the photoresists laminated into a multilayer configuration upon formation of the probe needle tip of the probe card, a second metal is laminated on any one of one or more stacked photoresist layers, thus firmly holding the photoresist layers on/beneath the metal.

Abstract: Disclosed are probe card needles manufactured using microfabrication technology, a method for manufacturing the probe card needles, and a probe card having the probe card needles. The probe needles are manufactured by forming, on a ceramic board, probe needle bases made of conductive metal, and a polymeric elastomer layer, by using photolithography and a photoresist, and continuously depositing conductive metal layers on the probe needle bases in such a manner as to be supported by the polymeric elastomer layer. The probe card comprises: a printed circuit board (PCB) which is connected to a test head for transmitting an electrical signal from a tester; a ceramic board located below the PCB and electrically connected to the PCB by a plurality of interface pins; a jig for mechanically holding the interface pins and the multilayer ceramic board to the PCB; and a plurality of probe needles attached to the lower surface of the multilayer ceramic board and making contact with electrical/electronic devices.
