Abstract

PURPOSE:To display a grade derivation by providing identifiers of cutouts or notches on both sides of a TAB tape. CONSTITUTION:4 U-shaped grade derivation display cutouts 3, two of which are formed at one side of a chip, are provided on both sides of the chip placing cutouts 2 of a TAB tape 1 as a lead frame of a tape carrier type. In this case, grade derivation of 16 zones can be displayed by the presence or absence of the cutouts 3. Accordingly, for example, 11 can be recognized by a binary method.
