Abstract
A substrate for a semiconductor device and a manufacturing thereof, and a semiconductor device using the same and a manufacturing method thereof are disclosed. For example, in the substrate according to the present invention, a core is eliminated, so that the substrate has a very thin thickness, as well, the length of electrically conductive patterns becomes shorter, whereby the electrical efficiency thereof is improved. Moreover, since a carrier having a stiffness of a predetermined strength is bonded on the substrate, it can prevent a warpage phenomenon during the manufacturing process of the semiconductor device. Furthermore, the carrier is removed from the substrate, whereby a solder ball fusing process or an electrical connecting process of the semiconductor die can be easily performed.
