Abstract :
The Through Silicon Via (TSV) process developed by Silex offers sub 50 mum pitch for through wafer connections in up to 600 mum thick substrates. The via process enables MEMS designs with significantly reduced die size and true "Wafer Level Packaging" - features that are particularly important in consumer market applications. The TSV technology also enables integration of advanced interconnect functions in optical MEMS, sensors and microfluidic devices. With several companies using the process already today and a line-up of potential users, the process is becoming a standard in the MEMS industry. This paper gives a brief introduction to the via formation process and focuses in more detail on the novel solutions made available by this enabling technology.
