Abstract

PURPOSE: A pad having a high integration degree is provided to enhance integration degree of a pad with maintaining stable electrical insulation state between adjacent wires, by heights of pads different from each other. CONSTITUTION: A pad is formed on a semiconductor IC or various substrates for a wire bonding(25). When defining the pad, the pads are arranged on many rows. Thereby, integration degree of the pad is enhanced. By properly regulating a height of a substrate(23) having a pad, heights of adjacent pads are differed, so that a stable electrical insulation state is maintained.

One end 15 of the fine wire 14 is melted and attached to the pad 11, and another end of the wire (not shown) may be a circuit or pad (such as an external substrate) to be electrically connected to the pad. By bonding to each other, electrical connection is established between the internal and external circuits.

종래 방법의 패드(11)들은 일렬로 배치되어 있으며, 상기한 방법으로 와이어 본딩(15)이 이루어 질 때 와이어의 본딩 사이즈의 제약으로 인해서 패드 부의 크기는 일정한 크기 이상이 요구되며, 이 때문에 밀집 도를 충분히 높일 수가 없게되는 문제점이 있다.The pads 11 of the conventional method are arranged in a line, and when the wire bonding 15 is made in the above-described manner, the size of the pad portion is required to be a certain size or more due to the limitation of the bonding size of the wire, and thus the density There is a problem that can not be raised sufficiently.

상기한 기술적 과제를 달성하기 위하여, 본 발명에 의한 패드 및 패드배치의 바람직한 일 실시 예를 첨부도면 도 2a 내지 도 2c를 참조하여 설명한다.In order to achieve the above technical problem, a preferred embodiment of the pad and the pad arrangement according to the present invention will be described with reference to the accompanying drawings, Figures 2a to 2c.

내부회로(21)의 선 폭은 패드(22)에 비해서 상대적으로 매우 가늘기 때문에 상기 패드와 패드 사이로 다수개의 내부회로들이 지나갈 수 있다. 상기한 방법, 즉 패드 사이로 회로들이 지나가게 하는 방법으로 내부회로와 연결된 패드 들을 이 열로 배치하고 이들 각 패드열의 높이가 서로 다르게, 보다 정확하게는 바깥쪽의 패드 열(a)이 안쪽의 패드 열(b)보다 더 낮게 형성되도록 미리 주 기판(23)의 높이를 형성시킨 후 상기한 패드 들을 정의하고 이들 각각의 패드에 와이어(24)의 일단을 본딩(25)하고, 상기 와이어의 또 다른 일단(도시 않음)을 외부기판의 패드(도시 않음)에 본딩 또는 적절한 방법으로 연결시키면, 인접한 와이어들 간에는 높이 차이가 유지되므로, 절연피복 등으로 보호되지 않은 와이어의 경우에도 안정적인 전기적 절연상태를 유지할 수 있게되고, 결국 와이어가 본딩된 패드의 밀집 도를 높일 수 있게 된다. 이때, 외부회로의 패드부도 상기한 방법으로 단차를 주어 형성시키면 외부회로 패드의 밀집도 역시 높일 수 있게 된다.Since the line width of the internal circuit 21 is relatively thinner than the pad 22, a plurality of internal circuits may pass between the pad and the pad. In this way, the pads connected to the internal circuit are arranged in this row in such a way that the circuits pass between the pads, and the height of each pad row is different from each other. The height of the main substrate 23 is formed in advance so as to be lower than b), and then the pads are defined and the one end of the wire 24 is bonded 25 to each of these pads, and the other end of the wire ( Bonding to the pads (not shown) of the external substrate in a suitable manner, the height difference is maintained between adjacent wires, so that even in the case of wires not protected by insulation coating, a stable electrical insulation state can be maintained. As a result, it is possible to increase the density of the pad to which the wire is bonded. At this time, if the pad portion of the external circuit is formed by giving a step in the above-described manner, the density of the external circuit pad can also be increased.

상기한 2열의 패드 배치는 일 실시 예에 불과하며, 3열 이상 다수 열의 패드 배치도 상기한 방법과 동일한 방법으로 얼마든지 가능함은 자명한 사실이다.The pad arrangement of the two rows is only an embodiment, and it is apparent that pad arrangements of three or more rows and multiple rows can be performed in the same manner as described above.

본 발명에 의하면, 패드에 연결되는 와이어의 본딩 사이즈를 더 이상 줄이지 않고도 패드의 밀집 도를 높일 수 있으며, 절연 피복 등과 같은 적절한 절연 막이 형성되지 않은 와이어를 사용하는 경우에도 인접한 와이어들이 서로 전기적으로 도통되는 문제를 방지할 수 있게된다.According to the present invention, the pad density can be increased without further reducing the bonding size of the wires connected to the pads, and adjacent wires are electrically connected to each other even when a wire without proper insulating film such as an insulating coating is used. This can prevent problems.
