Clever integration of new microelectronic/nanoelectronic technologies will continue to provide increased functionalities for modern products. Light Imaging, Detection, And Ranging (LIDAR) technology uses lasers to see though fog and darkness, and smaller less expensive LIDAR systems are needed for autonomous driving applications now being developed by dozens of major companies around the world. A significant step in the right direction has been taken by the US government’s Lawrence Livermore National Laboratory (LLNL) after working with AMFitzgerald on a MEMS mirror Light-field Directing Array (LDA) prototype.

For the past several years, AMFitzgerald has been developing the fabrication process for a novel MEMS micro-mirror array designed by Dr. Robert Panas’s research group at LLNL, as shown in this video. The technology has been developed specifically to serve LIDAR, laser communications, and other demanding applications where existing MEMS mirror array technologies are insufficient. The novel design offers exceptional speed and tilt range, with three axes (tip-tilt-piston), feedback control, and 99% fill factor. The technology is available for license from the LLNL Industrial Partnerships Office.

At the upcoming MEMS & Sensors Technical Congress, on May 11, Dr. Carolyn D. White will present a case study on how she developed this complex prototype and leveraged AMFitzgerald’s ecosystem of partners to integrate specialty processes. Dr. Alissa Fitzgerald—founder and principle of AMFitzgerald leading the development of innovative MEMS and sensor solutions for specialty applications—will be giving a keynote address on “Next Generation MEMS Manufacturing” at 9:10am May 17 during The ConFab. Dr. Fitzgerald has unparalleled expertise in how to best design MEMS for different fab lines, and is a speaker not to be missed.
