Provided is a method for fabricating semiconductor package and a semiconductor package fabricated using the same. The method for fabricating semiconductor package dopes a mixture including the polymer material and the solder particle on the substrate in which the terminal is formed and applies heat, and thus the solder particle flows (or diffuses) toward the terminal in the heated polymer resin to adhere to the exposed surface of the terminal, i.e., the side surface and upper surface of the terminal, thereby forming the solder layer. The solder layer improves the adhesive strength between the terminal of the semiconductor chip and the terminal of the substrate in the subsequent flip chip bonding process.
