Abstract
A method for producing damper structures on a micromechanical wafer. The method includes: providing an at least partially UV-transparent master mold for molding damper structures; inserting and pressing a micromechanical wafer into the master mold so that micromechanical structures in the wafer are aligned in relation to the damper structures; filling the master mold with UV-curing LSR and subsequent UV irradiation; and mold release and removal of the connected structure of the micromechanical wafer with attached dampers. A method for producing a singulated MEMS chip comprising a UV-cured damper is also described.
