发明名称 Probe card having deeply recessed trench and method for manufacturing the same
摘要 The present invention relates to a probe card that a probe of the probe card is movable only in a vertical direction using a trench to improve a electrical or a mechanical characteristic and to automatically limit the vertical movement thereof within a predetermined range. A pitch may be reduced so as to correspond to a decreasing distance between pads. A flatness of a probe tip may be maintained within a few micrometers using a semiconductor manufacturing process. 32 simultaneous parallel testing is possible contrary to a convention probe card. A wafer level testing is possible, and time and cost for a wafer testing are reduced.
