Slide 4: Advantages of Single Crystal Silicon Resonators
Advantages of Single Crystal Silicon Resonators • Single Crystal Silicon resonators are compatible with standard CMOS processing • Enables fabless models and massive production scaling • Moore’s law advantage • Single Crystal Silicon resonators can withstand very high encapsulation temperatures • El
Slide 5: Advantages of Single Crystal Silicon Resonators
Advantages of Single Crystal Silicon Resonators • EpiSeal Encapsulated single crystal silicon resonators do not drift • Other technologies require the use of metals, amorphous materials, polycrystalline materials, and epoxies. • Introducing other materials may cause fatigue or stress relaxation lead
Slide 6: Design of Resonators for Best Performance: Stress
Design of Resonators for Best Performance: Stress • Anchor placement minimizes stress sensitivity • Mechanical coupling between anchor and resonator reduces stress effects • Resonator system design corrects for stress 6
Slide 7: Design of Resonators for Best Performance: Optimizing Q
Design of Resonators for Best Performance: Optimizing Q • Resonator design adjusted to minimize Thermal Elastic Dissipation (TED) • Resonator design adjusted to minimize Anchor Losses • In-plane definition of features allows SiTime to tailor connection to anchors – difficult to achieve in quartz (ep
