I am looking towards designing some MEMS devices (esp. torsional Micro-mirrors) using Hybrid flip chip technology. My concern is that I am still thinking about wheather I should use silicion on glass (Pyrex) or SI-to-SI bonding. Could you, please, help with advices such that the drawbacks and the advantages of every assembly, and how they could affect the properties of the components and their integration density ?
