Abstract

An electronic semiconductor component with a housing structure and a cavity introduced into the housing structure is specified. The cavity comprises a base surface. Furthermore, the electronic semiconductor component comprises an auxiliary layer arranged on the base surface of the cavity and a marking penetrating the auxiliary layer at least as far as the base surface of the cavity. The marking comprises an optical contrast that depends on both an optical property of the housing structure and an optical property of the auxiliary layer. Furthermore, a method for producing an electronic semiconductor component is given.
