Abstract

A circuit substrate includes a dielectric layer and a plurality of conductive structures. The dielectric layer has a plurality of conductive openings, a first surface, and a second surface opposite to the first surface. Each of the conductive openings connects the first surface and the second surface. The conductive openings are respectively filled with the conductive structures. Each of the conductive structures is integrally formed and includes a pad part, a connection part, and a protruding part. Each of the connection parts is connected to the corresponding pad part and the corresponding protruding part. Each of the protruding parts has a curved surface that protrudes from the second surface. A process for fabricating the circuit substrate is also provided.
