Silicon Labs CMEMS Oscillator teardown reverse costing report by published Yole Developpement

Published on

First fully integrated, monolithic CMOS+MEMS oscillator device
Innovative Poly-SiGe Surface-Micromachining Process


The frequency control market is largely dominated by quartz products, but silicon timing solutions have a strong value proposition for some sub-markets.

The Si504 is the first silicon oscillator from Silicon Labs. Manufactured with the CMEMS process (CMOS + MEMS), the crystal elements are replaced by micromachined semiconductor resonators.

CMEMS process consists in a monolithic integration of a CMOS circuit with innovative Poly-SiGe (polycrystalline silicon-germanium) MEMS resonator structures manufactured directly above CMOS metallization.

The resonator is then vacuum encapsulated with a silicon cap using an eutectic wafer bonding process.

With a die size below 1mm², the Si504 is optimized to support high-volume, low-cost applications such as consumer electronics market.

Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10% correction on the manufacturing cost (if all parameters are cumulated) These results are open for discussion. We can reevaluate this circuit with your information.
