摘要 An IC package for an integrated circuit chip (3) includes a cavity (2) in which the IC chip (3) is mounted, a wall (12) surrounding the IC chip, and a groove (4) formed in the surrounding wall (12) extending to surround and communicate with the cavity (2). For fabricating the IC package, a resin of an amount more than necessary is filled in the cavity (2), and is pressed by a press plate.
