Paper Abstract
Area-varying tunable MEMS (MicroElectroMechanical Systems) capacitor with 608 comb fingers is developed. The 6 um-thick single crystal silicon MEMS structure is bonded to the pyrex glass substrate using the glass-silicon anodic bonding technique and chemical mechanical polish to make the designed capacitor. The pyrex glass is used as a substrate instead of the silicon for reducing the RF losses through the substrate. The measured capacitor shows the nominal capacitance of 1.4 pF, Q-factor of 4 at 1 GHz. The capacitor model is also developed and proved by Serenade software of Ansoft Corporation.
