Latest Patents

Among her latest patents is a breakthrough in waveguide and semiconductor packaging. This patent describes a method and apparatus for integrating individual III-V Monolithic Microwave Integrated Circuits (MMICs) into a micromachined waveguide package. The innovation allows for the screening of MMICs prior to their integration, ensuring that only known-good die are used, which ultimately increases yield. This technology is implemented in micro-integrated Focal Plane Array (mFPA) systems employed in sub-millimeter wave cameras. Furthermore, it accommodates the integration of different MMIC technologies into a single package, thereby achieving high levels of technological integration similar to those in multi-wafer Wafer-Level Packaging (WLP) solutions.

Another noteworthy patent led by Chang-Chien is the development of a low-power threshold integrated micro-plasma limiter. This device employs wafer-level fabrication techniques to create a plasma power limiter that incorporates other essential circuit elements. The design features a signal substrate and a ground substrate, which together form a sealed cavity containing an ionizable gas. When a signal exceeds a specified power level, it generates a plasma discharge that effectively limits power on the output signal line.
