[発明が解決しようとする問題点]
ところで上記した従来のポンディング法には次のような
問題点がある。[Problems to be Solved by the Invention] The conventional bonding method described above has the following problems.
■ワイヤポンディング法
■半導体素子4の接続部5を半導体素子4の内部にくる

に接触すると短絡する。さらに、極細金属線7の長さを
長くせざるを得ず、その長さを長くすると、トランスフ
ァーモールド成形時に極細金属線7が変形しやすくなる
。■ Wire bonding method ■ If the connection part 5 of the semiconductor element 4 is designed to be inside the semiconductor element 4, the ultrafine metal wire 7 has an extremely small wire diameter, It becomes easier to contact the outer peripheral edge 11 of the element mounting portion 2 of the lead frame 1. The ultra-fine metal wire 7 is attached to these outer peripheral edges 10 to 11.
It will short circuit if it comes into contact with. Furthermore, the length of the ultra-fine metal wire 7 has to be increased, and when the length is increased, the ultra-fine metal wire 7 becomes easily deformed during transfer molding.
従って、半導体素子4の接続部5は半導体素子4上の周
辺に配芒する必要が生じ、回路設計上の制限を受けざる
を得なくなる。Therefore, the connecting portions 5 of the semiconductor element 4 need to be arranged around the semiconductor element 4, which imposes limitations on circuit design.
■ワイヤポンディング法においては、隣接する極細金属

としである程度の間隔をとらざるを得ない。従って、半
導体素子4の大きさが決まれば必然的に接続部5の最大
数が決まる。■In the wire bonding method, in order to avoid contact between adjacent ultrafine metal wires 7, the pitch dimension of the connecting parts 5 on the semiconductor element 4 (distance between the centers of adjacent connecting parts)
We have no choice but to maintain a certain amount of distance between each other. Therefore, once the size of the semiconductor element 4 is determined, the maximum number of connection portions 5 is necessarily determined.
しかるに、ワイヤポンディング法では、このピッチ寸法
が通常0.2mm程度と大きいので、接続部5の数は少
なくせざるを得なくなる。However, in the wire bonding method, the pitch dimension is usually as large as about 0.2 mm, so the number of connecting portions 5 must be reduced.
O半導体素子4上の接続部5から測った極細金属線7の
高さhは通常0.2〜0.4mmであるが、0.2mm
以下にし薄型化することは比較的困難であるので薄型化
を図れない。The height h of the ultrafine metal wire 7 measured from the connection part 5 on the O semiconductor element 4 is usually 0.2 to 0.4 mm, but it is 0.2 mm.
Since it is relatively difficult to make the device thinner than below, the device cannot be made thinner.
■ワイヤボンディング作業に時間がかかる。特に接続点
数が多くなるとポンディング時間が長くなり生産効率が
悪くなる。■Wire bonding takes time. In particular, when the number of connection points increases, the bonding time increases and production efficiency deteriorates.
■何らかの要因でトランスファーモールド条件範囲を越
すと、極細金属線7が変形したり最悪の場合には切断し
たりする。- If the transfer molding condition range is exceeded for some reason, the ultrafine metal wire 7 may be deformed or, in the worst case, may be cut.
また半導体素子4上の接続部5に場いては、極細金属線
7と合金化されないA党が露出しているためAIg食が
生じ易くなり、信頼性の低下が生じる。Further, in the connection portion 5 on the semiconductor element 4, since the A layer which is not alloyed with the ultrafine metal wire 7 is exposed, AIg corrosion is likely to occur, resulting in a decrease in reliability.
■TAB法

ド部17が変形し易くなりインナーリード部を所望の接
続部5に接続できなかったり、インナーリード部17が
半導体素子4の接続部5以外の部分に接触したりする。■TAB method■ If the connecting part 5 of the semiconductor element 4 is designed to be inside the semiconductor element 4, the length of the inner lead part 17 of the carrier film substrate 16 becomes longer, so that the inner lead part 17 is easily deformed. Otherwise, the inner lead portion may not be able to be connected to the desired connection portion 5, or the inner lead portion 17 may come into contact with a portion of the semiconductor element 4 other than the connection portion 5.
これを避けるためには半導体素子4の接続部5を半導体
素子4上の周辺に持ってくる必要が生じ、設計上の制限
を受ける。In order to avoid this, it is necessary to bring the connecting portion 5 of the semiconductor element 4 to the periphery above the semiconductor element 4, which is subject to design limitations.
■TAB法においても、半導体素子4上の接続部のピッ
チ寸法は0.09〜0.15mm程度とる必要があり、
従ってワイヤポンディング法の問題点■で述べたと同様
に、接続部数を増加させることはむずかしくなる。■Even in the TAB method, the pitch dimension of the connection parts on the semiconductor element 4 must be approximately 0.09 to 0.15 mm.
Therefore, similar to the problem (2) of the wire bonding method, it is difficult to increase the number of connections.
■キャリアフィルム基板16のインナーリード部17が
半導体素子4の接続部5以外の部分に接触しないように
させるため所望のインナーリード部17の接続形状が要
求されコスト高となる。(2) In order to prevent the inner lead portions 17 of the carrier film substrate 16 from coming into contact with portions other than the connection portions 5 of the semiconductor element 4, a desired connection shape of the inner lead portions 17 is required, which increases costs.

■CCB法
■半導体素子4の接続部5に一半田バンプ31を形成さ

On the other hand, if the amount is too small, the connecting portion 5 of the semiconductor element 4 and the connecting portion 33 of the substrate 32 will not be connected and electrical continuity will not be established. In other words, the reliability of the connection becomes low. Furthermore, there is a problem in that the amount of solder and the solder shape of the connection affect the reliability of the connection (Technical data of the Brazing Technology Research Group, No. 017-'84. Published by the Brazing Technology Research Group).
このように、半田バンプの量の多少が接続の信頼性に影

Therefore, the reliability of the connection becomes poor.
