Study on the Polishing Mechanism of Low Temperature Co-Fired Ceramic for Microsystem Application
Multilayer ceramics based on the low-temperature co-fired ceramics (LTCC) are gaining increasing interests in the manufacturing of highly-integrated systems for microelectronic and micro-system applications. The polishing experiments of sintered LTCC using a custom-built precision polishing machine are reported in this paper. First, a micro-fluidic distributor was fabricated using LTCC. Then, the polishing of this meso-MEMS system was studied using several polishing parameters. By optimizing the polishing parameters, the surface roughness can be reduced to 4 nm.
