What is Soft chemistry assisted On-chip Integration of Nanostructured quartz-based Piezoelectric Microelectromechanical System about?

The development of advanced piezoelectric quartz MEMS for sensing and precise frequency control applications requires the nanostructuration and on chip integration on silicon of this material. However, the current quartz manufacturing methods are based on bonding bulk micromachined crystals on silicon, which limits the size, the performance, the integration cost and the scalability of quartz micro devices. Here, we combine chemical solution deposition, soft nanoimprint lithography and top down microfabrication processes to develop the first nanostructured epitaxial 100 quartz 100 Si piezoelectric cantilevers. The coherent Si quartz interface and film thinness combined with a controlled nanostructuration on silicon insulator silicon technology substrates provides high force and mass sensitivity while preserving the mechanical quality factor of the microelectromechanical systems. This work proves that biocompatible nanostructured epitaxial piezoelectric quartz based MEMS on silicon can be engineered at low cost by combining soft chemistry and top down lithographic techniques.
