Abstract
A semiconductor device and a method for producing it, and the use of the electrospinning method is disclosed. In one embodiment, delamination of the plastic housing composition from the circuit carrier can occur under loading, which can lead to the failure of the semiconductor device. For better adhesion, an adhesion-promoting layer having fibers applied by electrospinning is arranged between the circuit carrier and the plastic housing composition.
