に外部ピン数の低減が要求されている。In recent years, integration of semiconductor devices has been promoted. On the other hand, in order to increase the mounting density, there is a demand for a smaller and thinner package for encapsulating a semiconductor chip. The package size is determined by the number of external pins. In particular, in a semiconductor memory having a multi-bit input / output configuration, the number of power supply pins increases in proportion to the increase in the number of input / output pins. Therefore, a reduction in the number of external pins is required to reduce the package size.

等の誤動作を起こす恐れがある。In a semiconductor memory having multi-bit input / output lines, when each of the inverter circuits INV1 to INVn operates, a current I is supplied to each of the inverter circuits INV1 to INVn.
1 to In flow. Therefore, a current obtained by adding the currents I1 to In flows to the high potential power supply terminal VCC and the low potential power supply terminal VSS, and an excessive potential drop occurs due to the power supply line resistance in the chip. If the potential drop exceeds the voltage range that guarantees the operation of the semiconductor memory, there is a possibility that the memory may malfunction or the memory may not operate properly or the contents of the memory may be erased.

Actually, if the two power supply terminals VCC1 to VCCn and VSS1 to VSSn are provided for the input / output terminals DQ1 to DQn, the chip becomes large only by those terminals.

A method of connecting with a conductive metal tape T using a B (Tape Automated Bonding) technique is used. This TA
FIG. 12 shows a TSOP using the B technique. A conductive adhesive 11 is applied to each of the external pads 2 and the leads of the chip, and a conductive tape T is bonded.

という問題があった。However, since all the tapes are formed collectively by punching, only a two-dimensional planar structure is allowed, and the leads cannot be straddled like wires. Therefore, the chip 1 is set to TSO using TAB technology.
When trying to seal in a P-type package, tapes and leads must be provided corresponding to all the external pads 2 formed on the chip 1 as shown in FIG. As a result, since the number of leads increases, the package size of a package for encapsulating a chip increases, and there is a problem that the mounting area when mounting the package on a substrate increases.

る。On the other hand, in order to further reduce the mounting area when mounting a package on a substrate, an SVP (Surface Ve
rtical Package) type package. As shown in FIG. 14, similarly to the TSOP, the SVP is formed using TAB technology so that the package is thin.

ど、そのピンピッチは細かくなる。As shown in FIG. 15, the SVP type package is a package for mounting vertically on a substrate, and external pins are provided only on one side of the package. As a similar package, ZIP (Zigzag Inline Pa)
Although there is a package of the SVP type, the pitch of the external pins is smaller and the package size is smaller than that of the ZIP type. The package size of the ZIP type is determined by the number of external pins. On the other hand, SVP
The mold determines the package size substantially according to the chip size of the semiconductor chip to be stored therein. When the number of external pins increases, the pin pitch of the external pins is set small. Accordingly, the pin pitch of the SVP type becomes finer as the number of external pins increases.

あった。As shown in FIG. 14, in the case of the SVP type, the tape T is formed by punching in the same manner as in the case where the tape T is sealed in the TSOP type, so that only a two-dimensional planar structure is allowed. For this reason, when encapsulating using the TAB technology, external pins are required by the number of pads to be connected. As a result, SV
When a memory of a multi-bit input / output configuration is sealed in a P-type, there is a problem that as the number of power supply pads increases, the number of external pins also increases, the pitch of the external pins becomes narrower, and mounting on a substrate becomes difficult.
