Latest Patents

Chi-Sheng Chao holds a patent for a manufacturing method of a flip chip package. This method involves several key steps. Initially, a chip with an active surface featuring multiple bumps is provided. The active surface of the chip is then positioned on the upper surface of a substrate, establishing an electrical connection. A gap is formed between the chip and the substrate, which is subsequently filled with an underfill material. A first curing process partially hardens the underfill, transforming it into a partially hardened state. The assembly is then flipped, allowing the substrate to be positioned above the chip. A second curing process fully hardens the underfill, completing the manufacturing process.
