Abstract

A capsulation body is composed of the semiconductor chip, the lead frame and the packaging body. The chip includes two long edges, two short edges, one active face and several marginal electrode pads. The marginal electrode pads are set along the long edges are the short edges. The lead frame is composed of the several up lead typed lead wires and the standard typed lead wires as well as the outer lead wires. The up lead typed lead wires are connected to the electrode pads on one short edge electrically. The standard typed lead wires are connected to electrode pads on the other short edge and the two long edges electrically. The outer lead lead wires are coupled to the up lead typed lead wires and the standard typed lead wires. The packaging body encapsulates the chip and the lead frame.

Description

technical field [0001] The present invention relates to a semiconductor chip packaging body, in particular to forming integrated circuits of different designs on a semiconductor chip with peripheral electrode pads by using top lead type leads. Background technique [0002] figure 1 It shows a 64Mb semiconductor chip with 32 I / O pins. like figure 1 As shown, on the two short sides of the semiconductor chip 100, there are respectively 24 electrode pads 10a, 10b and standard-type leads 21, 22, 23, 24 connected to the 24 electrode pads. In addition, the semiconductor chip 100 can be divided into four major regions I, II, III, and IV. There are four random access memories R (random access memory) in each area, and eight electrode pads are responsible for data input and output. However, semiconductor crystals of this design have been seldom used. [0003] figure 2 Is to show another 64Mb semiconductor chip with 16 I / O pins. like figure 2 As shown, there are 24 electrode ...
