Abstract
A semiconductor packaging substrate is provided, which includes a build-up circuit structure, at least one fiducial marker structure, and an insulating protective layer. The fiducial marker structure includes a fiducial marker and a second insulating layer covering the fiducial marker. The second insulating layer is made of a transparent insulation material, so that the fiducial marker inside the second insulating layer can be seen through a CCD lens or tool maker microscope for alignment so as to easily create a smaller see-through area and the process parameters can be easily controlled. Besides, the disclosure further provides a manufacturing method for the semiconductor packaging substrate.
