Abstract
A semiconductor packaging substrate is provided and includes: an insulating layer, a thinned circuit structure formed of circuit layers and conductive posts stacked on one another embedding in the insulating layer, and a supporting structure formed on the insulating layer and having at least one through hole exposing the conductive posts. As such, before a subsequent packaging operation, the packaging substrate can be electrically tested and screened so as to prevent a defective packaging substrate from being misused in the subsequent packaging operation and hence avoid the loss of normal electronic elements. A method for fabricating a semiconductor packaging substrate and a packaging process using the semiconductor packaging substrate are also provided.
