Abstract
An FBGA semiconductor component has a chip side for receiving a semiconductor chip, a solder ball side for applying solder balls on ball pads, and a bonding channel embodied as an opening between the chip side and the solder ball side and serving for leading through wire bridges between the semiconductor chip and bonding islands on the solder ball side. The bonding channel has side areas extending between the chip side and the solder ball side and can be closed off with a housing part comprising potting composition. Positively locking elements for a potting composition are arranged in that region of the substrate in which the housing part is produced.
