ABSTRACT:
A tape carrier used for assemblage of integrated circuit chips based on a TAB system, comprises a plurality of square frames, each including a substantially square opening for defining a position of an integrated circuit chip to be bonded to the frame, the square opening being formed within a mold area of the frame on which, when the integrated circuit chip mounted at the square opening and bonded to the frame is resin-molded, the resin-molded integrated circuit chip extends. At least two substantially rectangular first openings are formed within the mold area at a space between the square opening and an outer periphery of the mold area. A plurality of lead groups, extend from an inside of the square opening to positions adjacent to a periphery of the frame by crossing one of the first openings. At least one second opening is formed at a space between adjacent two of the first openings, and such that none of the leads extend across the second opening, thereby allowing a resin to flow therethrough in a process of resin-molding the integrated circuit chip mounted at the square opening.
