    Abstract: A method for forming a shielding layer over a semiconductor package is provided. The method comprises: providing a jig having a metal frame and a carrier tape attached onto the metal frame via an adhesive layer; forming an opening through the adhesive layer and the carrier tape; disposing a semiconductor package on the jig over the opening such that the semiconductor package is supported on and attached to the carrier tape via the adhesive layer; forming a groove in the adhesive layer and around the opening by isotropic etching; forming a shielding layer over the semiconductor package and the jig; and removing the semiconductor package with the shielding layer from the jig.

    Abstract: A method for attaching a heat spreader to a semiconductor package is provided. The method comprises: providing a semiconductor package, wherein the semiconductor package comprises a package substrate, a semiconductor component mounted on the package substrate and a mold cap formed on the package substrate and encapsulating the semiconductor component, and wherein the mold cap comprises a laser-activatable mold compound; removing a portion of a thickness of the mold cap above the semiconductor component by laser ablation to form a cavity in the mold cap and transform the laser-activatable mold compound at an inner surface of the cavity to a conductive layer; dispensing a thermal interface material (TIM) in the cavity to form on the conductive layer a TIM layer that protrudes from the mold cap; and attaching the heater spreader to the semiconductor package at least through the TIM layer.
