Hybrid micro-integration of semiconductor devices, micro-optics, fiber-optics and micro-electronics is of growing interest for automotive, computer, telecommunication, business equipment and consumer applications. A large variety of the functions and components within these photonic devices and missing packaging standards make most of them not mass producible and therefore expensive. In addition most of them need reproducible and accurate alignment in the micron or even sub-micron range. Automated processes are necessary to get the accuracy and the reproducibility for high yield fabrication. Expensive production equipment is available mostly especially adapted to the specific product. The machines do need heavy granite bases and a temperature controlled fabrication environment to realize the requirements mentioned above. They appear as dinosaurs compared to the tiny products fabricated. Cost reduction can be achieved by using only partly automated production sequences in a modular desk top factory. Consequently we have miniaturized the robots, the factory framework and the tools for handling, dispensing and inspection. For the first time an exchangeable tool assortment with a standardized mechanical, electrical and fluidic interface between the robot and the end-effector is available. The modularity allows a flexible and re-useable set-up of the production equipment. The fabrication process uses a new technology with a closed loop control of the robot directly correlated to the assembly process to get sub-micron accuracy. The control signals are determined from the deviation of a component relative to the assembly position with miniaturized microscopes integrated to the tools[2]. Solutions with multiple fiber handling and automatic process control for the joining of fibers to micro-optics and microoptics to micro-benches, the assembly of silicon fiber-optical switches and of two-dimensional fiber arrays will be shown. Also a technology for the fabrication of fiber-optic collimator arrays with back reflection losses well above 70 dB will be presented.
