The paper presents different approaches for hermetic wafer level packaging of oscillator
components like quartz crystals or silicon resonators. The proposed concepts involve
technologies like TSV formation into passive or active silicon wafers, formation of proper
bond frames on interposer, ASIC or cap wafers as well as hermetic bonding using AuSn
soldering either in wafer to wafer style or with reconfigured components on a carrier wafer.
