Abstract

Disclosed are a carrier substrate including an insulating base material with a copper foil layer formed on at least one surface thereof, a metal layer formed on the copper layer and having a length shorter than that of the copper foil layer, and an insulating layer formed on the metal layer, a fabrication method thereof, a printed circuit board (PCB) using the same, and a fabrication method thereof. Because there is no land at the via and core in the substrate, because a circuit pattern connected with the via can be formed to be finer, so the circuit pattern can be highly integrated and the substrate can become thinner. Thus, a printed circuit board (PCB) having a smaller size and reduced number of layers can be fabricated.
