A method for manufacturing a semiconductor package, comprising:
- providing a device chip, wherein the device chip has an active area and an inactive area arranged around the active area;
- forming an opening within the inactive area in a lower surface of the device chip;
- disposing a protecting material within the opening and over the lower surface of the device chip;
- providing a carrier and an adhesive layer disposed over the carrier;
- flipping the device chip upside down before forming the openings, so that front sides of the device chips face the adhesive layer and are in contact with the adhesive layer;
- and
- removing the carrier and the adhesive layer after disposing the protecting layer within the opening and over the lower surface of the device chip.
