Latest Patents

Doo Yun Chung holds a patent for a "Probe card having deeply recessed trench and method for manufacturing the same." This invention relates to a probe card that allows the probe to move only in a vertical direction, utilizing a trench to improve electrical and mechanical characteristics. The design automatically limits the vertical movement within a predetermined range, enabling a reduced pitch that corresponds to the decreasing distance between pads. The flatness of the probe tip is maintained within a few micrometers using a semiconductor manufacturing process. This innovation allows for 32 simultaneous parallel testing, which is a significant improvement over conventional probe cards. Additionally, wafer-level testing becomes possible, reducing both time and costs associated with wafer testing.
