【0007】
【発明の実施の形態】
以下に、この本発明の実施例を図に基づいて説明する。
図1(a)および(b)に示す様にウエハー1には複数のトランジスタを設けた複数の半導体チップ2が設けられ、半導体チップ2には外部との接続を目的としたバンプ3が形成されている。本実施例では半田(Sn−Pb)バンプを用いる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, examples of the present invention will be described with reference to the drawings.
Figure 1 (a) and (b) a plurality of semiconductor chips 2 provided with a plurality of transistors is provided in the
図1(c)に示す様ににウエハー1かそれ以上の大きさの基板4上にウエハー1上の半導体チップ2、バンプ3と同様にレイアウトされた電極5が形成されている。そして基板4の電極5に印刷法やスタンピング法を用いて半田バンプ接続の為のフラックスを転写する。もちろん半導体チップ2のバンプ3ではなく、基板4の電極5側にフラックスを転写しても良い。
As shown in FIG. 1 ( c ), electrodes 5 laid out in the same manner as the semiconductor chips 2 and bumps 3 on the
図4(b)に示す様にウエハー1の裏面部をローラー10で均一に押す事により、ハーフカット部9が破壊し半導体チップ2単位でウエハー1を分離する。
図4(c)に示す様に圧力によりカットした切断部が裏面にも表れておりその切断部をガイドとして、基板をダイシングできることから、基板にダイシング用のアライメントマークを設けなくても容易に切断する事ができる。
As shown in FIG. 4B, by uniformly pressing the back surface portion of the
As shown in FIG. 4C, a cut portion cut by pressure also appears on the back surface, and the substrate can be diced using the cut portion as a guide. Therefore, cutting can be easily performed without providing an alignment mark for dicing on the substrate. Can be done.
