Abstract
Described herein is a method of forming wafer-level packages from a wafer. The method includes adhesively attaching front sides of first integrated circuits within the wafer to back sides of second integrated circuits such that pads on the front sides of the first integrated circuits and pads on front sides of the second integrated circuits are exposed. The method further includes forming a laser direct structuring (LDS) activatable layer over the front sides of the first integrated circuits and the second integrated circuits and over edges of the second integrated circuits, and forming desired patterns of structured areas within the LDS activatable layer. The method additionally includes metallizing the desired patterns of structured areas to form conductive areas within the LDS activatable layer.
