Abstract:
1. A fabrication method of a semiconductor package without a chip carrier, comprising: preparing a metallic carrier having a first surface and a second surface opposing the first surface, with grooves and metal studs corresponding to the grooves formed on the first surface; filling the grooves with a first encapsulant, with top surfaces of the metal studs being exposed from the first encapsulant; forming bonding pads on the metal studs, and electrically connecting the bonding pads to the metal studs; electrically connecting a semiconductor chip to the bonding pads on the metal studs; forming on the first surface of the metallic carrier a second encapsulant that encapsulates the semiconductor chip and the bonding pads; and removing the metallic carrier, to expose bottom surfaces of the metal studs and the first encapsulant.
