Abstract
An electronic component such as a surface acoustic wave component has a chip a piezoelectric substrate with electrically conductive structures thereon and a base plate having external electrical terminal elements that are contacted to the electrically conductive structures of the chip. A protective film is applied onto the chip surface carrying the electrically conductive structures. The surface of the protective film facing away from the piezoelectric substrate carries electrical contact elements that are connected, to the electrically conductive structures of the chip via through-contacts in the protective film and/or directly via bumps, as well as to the electrical terminal elements of the base plate.
