Abstract:
1. A method for producing a plurality of semiconductor components comprising: producing a semiconductor wafer with a plurality of semiconductor chip positions arranged in rows and columns; applying microelectromechanical structures and wiring structures on at least an active top side of the semiconductor wafer in the semiconductor chip positions; applying of wall structures of a polymer on the active top side to surround the microelectromechanical structures in the semiconductor chip positions; precuring the polymer with precrosslinking of the chain molecules of the polymer; producing a covering wafer made from a semiconductor wafer or a metal wafer or a plastic wafer or a glass wafer; coating the covering wafer with a layer of a polymer of identical type as covering for the walls; precuring the polymer with precrosslinking of the chain molecules of the polymer; applying of the covering wafer with the precured polymer layer to the semiconductor wafer with precured wall structure; curing the polymers lying one on top of another with crosslinking of the chain molecules of the polymers to form cavities over the microelectromechanical structures, wherein the wiring structures for each of the microelectromechanical structures are applied with a portion external to the cavity which is covered by the polymer of the wall structures and a portion extending into the cavity for electrical connection to the microelectromechanical structure, with any through-connections through the wafer being made to the portion of the wiring structures external to the cavities; and separating the semiconductor wafer to form individual semiconductor components.
