Abstract

PURPOSE:To realize a multi-pin semiconductor device, and facilitate its design, manufacture, etc., by making the gap between a lead arranged in the vicinity of a tab suspension lead out of leads and the tab suspension lead as small as possible. CONSTITUTION:A tab 14 is retained by linking the end-portion of a tab suspension lead 21 with the vicinity of a corner of a sealing body corresponding with the corner of the tab 14. The gap 22 between a lead 11 and the tab suspension lead 21 is made as small as possible, by arranging the lead 11 of a lead frame 18 so as to be adjacent to the tab suspension lead 21. The lead 11 is so formed that the end-portion of the lead which is adjacent to the tab suspension lead 21 and extends from the part between the tab suspension lead 21 and the corner of the tab 14 has the same direction as a plurality of the leads 11 which extend from one side of the tab 14 extending in the longitudinal direction to one side where the tab suspension lead 21 is arranged. Thereby a multi-pin semiconductor device can be realized, and its design, manufacture and packaging are facilitated.

Description of the Related Art Generally, a flat package type semiconductor device can be made thinner and have a larger number of pins than a dual inline type package, and a chip carrier package can be mounted on a mounting circuit board (printed circuit board). The demand is increasing due to the advantage that almost the same level of mounting work is required. In this type of semiconductor device, a semiconductor element pellet is usually fixed to a lead frame obtained by stamping and molding a thin metal plate, and an electrical connection is made between the lead and the lead. It is square (square, rectangular) and has a thin-walled package shape and is sealed with plastic. When the package has a rectangular planar shape as described above, one corner of the package body 1 is chamfered as shown in FIG. 1, and the chamfered portion 2 is used as an index of a plurality of pins (leads) 3. -ing

設することにより多ピン化に対応せざるを得ない。In recent years, semiconductor devices tend to have higher density and more pins. On the other hand, for designing, manufacturing, or mounting reasons, it may be required to keep the shape and size of the package body constant. Therefore, in such a case, it is inevitable to increase the number of pins by reducing the lead pitch as much as possible and arranging the pins 3 by making maximum use of the length of the package body 1 on the four circumference side.

もある。However, in the conventional semiconductor device, since the chamfered portion 2 as an index is provided, the pin 3 is not provided in this portion, and therefore the utilization on the four sides of the package body is reduced, which is often a problem. It is an obstacle to pinning. In addition, since the pins are not provided in the chamfered portion 2, the pins cannot be arranged symmetrically with respect to the center 0 of the package body 1 particularly on the peripheral side surfaces 1a and 1b which are in contact with the chamfered portion 2. Disadvantages may occur in manufacturing and implementation. As will be described in more detail later, since the chamfered portion 2 is not provided with a pin, the corresponding portion of the lead frame corresponding thereto is not provided with a lead, which causes leakage of the plastic and deteriorates the appearance and the package. There is also the problem of inducing chipping and reducing the commercial value.
