摘要： A process for the manufacture of encapsulated semiconductor dies and/or of encapsulated semiconductor packages or for the manufacture of an encapsulation of semiconductor dies and/or of semiconductor packages comprising the steps: (1) assembling a multitude of bare semiconductor dies on a temporary carrier, and (2) encapsulating the assembled bare semiconductor dies, characterized in that an aqueous hydraulic hardening inorganic cement preparation is applied as encapsulation agent in step (2).
