Latest Patents
One of Y J Lee's latest patents is a method for manufacturing probes of a probe card. This method involves providing a blocking plate on an electroplating tank, which has multiple openings corresponding to the layout of contact pads on a probe head. The process allows for continuous electroplating after the contact pads interact with the electroplating solution through the openings. By moving the probe head according to the desired shape, probes are formed with good uniformity in elasticity and height, enhancing the quality of electrical contact during wafer probing. This method also reduces process lead time and fabrication costs.
Another significant patent is a flip-chip type semiconductor device designed to reduce signal skew. This device includes a chip with bonding pads and multiple bumping pads. Each bonding pad is connected to corresponding bumping pads via a metal redistribution trace, which is covered by a passivation layer. The equal trace lengths of the metal traces help in minimizing signal skew, thereby improving device performance.
