发明名称 Method of fabricating cantilever type probe and method of fabricating probe card using the same
摘要 Disclosed is a method of fabricating a cantilever type probes. According to this method, after forming grooves each in tip portion and dummy tip portion regions of a substrate, the tip portion and dummy tip portion are formed with filling the grooves of the tip portion and dummy tip portion regions. A sacrificial layer is formed to cover the dummy tip portion region including dummy tip portion. A beam portion is formed in connection with the tip portion, extending upward the dummy tip portion including the sacrificial layer. The method includes steps of selectively etching the substrate of the tip portion and floating the tip portion from the substrate. Accordingly, it minimizes physical and chemical damages on the tip portion while fabricating a probe card, providing stability thereto with smaller defects of the tip portion.
