Abstract
This disclosure provides a package substrate fabrication method including: providing a carrier; forming a first dielectric layer on the carrier while enabling the first dielectric layer to be patterned including an opening; forming a first conducting unit on the carrier while enabling the first conducting unit to fill up the opening, a height of the first conducting unit at the opening larger than a thickness of the first dielectric layer, and a width of the first conducting unit larger than a width of the opening; forming a second dielectric layer on the first conducting unit; forming a second conducting unit on the second dielectric layer; forming a third dielectric layer on the second conducting unit; removing the carrier and the first dielectric layer while enabling the part of the first conducting unit in the opening to be removed; and forming a fourth dielectric layer to cover the first conducting unit.
