Latest Patents

One of Dong Li's latest inventions is a metal spring anchor for advanced packaging. This fan-out packaging system includes a dedicated frame with associated movable metallic spring features for incoming known-good-die (KGD). The movable spring anchors, along with the boundaries of the frame, secure the KGD in its designated position during electromagnetic compatibility (EMC) implementation and subsequent processes. The accuracy of the KGD positions during the wafer reconstitution process is primarily influenced by dicing accuracy. This proposed system is a cost-effective solution, as it does not require expensive software or tools and avoids low throughput site-to-site lithography corrections after metrology is performed for each flash field. This system is particularly beneficial for chiplets that consist of component chips from various technologies and substrates made of different materials. Additionally, the frames can serve multiple functions within the packaged system, such as electromagnetic shielding, heat dissipation, or even as RF antennas and other passive or active components.

Another significant invention by Dong Li is a portable air purification system. This hand-held air cleaning device features an airflow pipeline made of highly reflective and low absorptive material for UVC or UVB light, which also acts as a UV light waveguide. The system includes a thermoelectric (TEC) cooled LED light source, an airflow warm-up mechanism, and a UV light absorption and air cleaning enhancement device. This innovative air purification system is particularly useful for travelers and office workers during flu and hay-fever seasons.
