Latest Patents

One of his latest patents is a sensor package structure that includes a substrate, a sensor chip, a plurality of wires, a supporting frame, a transparent cover, and a molding compound. The substrate features a chip bonding region and several first pads outside this region. The sensor chip is placed on the chip bonding region and contains a sensing region along with multiple second pads. Each wire connects one of the first pads to one of the second pads. The supporting frame is positioned above the substrate and/or the sensor chip, incorporating a positioning portion. The transparent cover is secured above the sensor chip by this positioning portion, maintaining a vertical distance between them. The molding compound fills the space between the substrate and the supporting frame, covering part of the upper surface of the supporting frame.

Another significant patent is a method for reducing tilt of the optical unit during the manufacture of an image sensor. This method involves several steps, including providing a semimanufacture of the image sensor, conducting a preheating process, applying adhesive, mounting the optical unit, and packaging. The preheating process ensures a stabilized environment during the adhesive application and optical unit mounting, which helps maintain the optical unit's flatness once attached. This method effectively reduces the chances of tilt and cracking, contributing to a higher yield rate.
