Description In this paper, eutectic bonding using localized heating for micro-electro-mechanical systems (MEMS) packaging applications is described. Polysilicon line is used as a local heater. The interface of silicon and gold is used for formation of eutectic bonding. Using only 2V source, high temperature (>700ºC) in a bonding region is obtained without heating adjacent structures. Gold-silicon eutectic bond is isolated electrical connections using 1μm thick silicon dioxide layer. Device RF response has negligible effect of packaging using gold-silicon eutectic bonding till 13GHz. Hence, inbuilt custom cavity hermetic encapsulation is possible without heating device area.
