New platform for the next generation optical components, del 2

Offentlig prosjektsammendrag

The hybrid MEMS solution is new and innovative, and offers some possibilities that are not available in ordinary MEMS processing. Together with other achievements in ongoing R&D activities, we will have a good platform for introducing new products and a combined solution like AF+OIS in one die. The big difference to normal MEMS processing is the use of micro-assembly on die-level to build small three-dimensional structures cheaply and efficiently. The driving force for this innovation is a smaller footprint and a lower total cost for the final product. Another important element is an increased degree of freedom in design coming from the possibility of using different process architecture on separate wafer that has been optimized for a specific functionality. It will also potentially improve performance and functionality. Developing new MEMS products is not easy with the current technology available in the MEMS industry and our work so fare have highlighted the need for poLight to investigate a more affordable solution to generate new products. This include the use of Voice Coil Motor (VCM) or Shape Memory Alloy (SMA) as well as bulk Piezo actuators, which are more mature technology and already proven technology in the mobile industry. The poLight team does not want to close the original path completely, but would like to propose to re-open to a wider range of actuator solution in order to make the better/best choice of technology to realize the set of new functionalities and products. In 2020 we have continued the work described above. To cover the most relevant market for HybridMEMS we have focused the work on larger apertures (3,5 mm). This has forced us to develop a polymer with a higher refractive index. This is possible, but quit challenging with respect to keeping a low E-modules (softness). A relatively simple demonstrator has been built to show potential customers how it works.
