Assembled micro-electromechanical-systems microcolumn from a single layer silicon process Available to Purchase

We report a novel microcolumn fabrication method using automated micro-electro-mechanical-systems (MEMS) assembly. Different microcolumn components, including deflectors, lens elements, and apertures, are fabricated on a highly doped $50μm$ thick silicon-on-insulator (SOI) wafer. These components with compliant connectors are then assembled onto compliant MEMS sockets fabricated on the same wafer using MEMS NanoEffectors™ and automated assembly. The self-aligning nature of MEMS sockets yields submicron lateral alignment and less than 0.1° angular misalignment. The measured resonant frequency is $593Hz$ for first generation assembled components; the footprint of the microcolumn is less than $1cm2$⁠. We have successfully built a mechanical prototype microcolumn for technology demonstration and as a proof of concept. Second generation design is under development.
