Latest Patents

One of Kuan's latest patents focuses on "Bulk silicon mirrors with hinges underneath." This invention provides a method and apparatus for fabricating a MEMS apparatus that features a bulk element with hinges positioned underneath. The bulk element is typically made from single-crystal silicon, utilizing bulk micromachining techniques. The hinges are crafted from thin films through surface micromachining techniques. A key advantage of this design is that it maximizes the surface area of the bulk element, making it fully usable for applications such as optical beam manipulation. This innovation is particularly beneficial for creating arrayed MEMS devices, like an array of MEMS mirrors with a high optical fill factor. By effectively combining both bulk and surface micromachining techniques, the resulting MEMS mirror is equipped with a large, flat surface and flexible hinges, allowing for a substantial rotational range at modest electrostatic drive voltages.
