Latest Patents

One of his latest patents is a method for forming a wafer level package. This method involves equipping the package with solder balls on the top surface and encapsulating it with a stress buffer layer made of elastomeric material. The process begins with the formation of solder balls on bond pads on the wafer's surface, followed by the application of an elastomeric material layer. This layer serves as both a stress buffer and a thermal expansion buffer, ensuring the integrity and reliability of the integrated circuits once they are severed from the wafer.

Another significant patent by Kung is a dual-photoresist method for forming fine-pitched solder bumps on flip chips. This innovative approach utilizes two separate layers of photoresist to achieve precise patterning. The first thin photoresist layer allows for accurate imaging without the focusing issues typically associated with thicker layers. This method enhances the electrical characteristics of the solder bumps, ensuring a clean removal process without damaging the already formed bumps.
