Patent ID: 7927920

Claim:
A method of manufacturing an electronic component package, the electronic component package comprising: a base incorporating a plurality of external connecting terminals; and at least one electronic component chip that is bonded to the base and electrically connected to at least one of the external connecting terminals, the method comprising the steps of: fabricating a wafer incorporating a plurality of sets of external connecting terminals corresponding to a plurality of electronic component packages, and a retainer for retaining the plurality of sets of external connecting terminals, the wafer including a plurality of pre-base portions that will be separated from one another later so that each of them will thereby become the base; bonding at least one electronic component chip to each of the pre-base portions of the wafer; and cutting the wafer so that the pre-base portions are separated from one another and a plurality of bases are thereby formed, the cutting being performed after the bonding, wherein: the wafer has a top surface and a bottom surface; and the base has a top surface and a bottom surface that correspond to the top surface and the bottom surface of the wafer, and a side surface that couples the top and bottom surfaces to each other; the method further comprising forming the side surface of the base such that a portion of each of the plurality of external connecting terminals protrudes from the side surface, wherein: the electronic component package has a top surface and a bottom surface that are opposite to each other, the bottom surface of the electronic component package corresponding to the bottom surface of the base; and none of terminals or electrodes that are electrically connected to any of the plurality of external connecting terminals are exposed in either the top surface or the bottom surface of the electronic component package.
