For smart systems integration and More-than-Moore technologies the implementation of several components is necessary for reaching a higher functionality and smaller system dimensions. Therefore special substrates, e. g. flexible ones or even interposer made from Silicon, Glass, and Ceramics could be used for mounting and connecting sensors, actuators, and electronics as chips or chip-sized-packages.
Interposers
Within 3D integration for smart systems Silicon and Glass interposer are of increasing importance. One main reason is the possibility to adapt different design and technology rules from microelectronics and MEMS processes. With interposers a redistribution of interconnects could be realized and at least a chip sized package (CSP) with different components is enabled.
