半導体ウェハ(厚さ500μm)にブレードダイシング加工により格子状(10mm×10mm)の切り込み溝を形成した。切り込み溝の深さは、100μmとした。
次に、この半導体ウェハの表面を保護テープにて保護し、厚さが75μmとなるまで裏面研削を行い、分割された個々の半導体チップ(10mm×10mm×75μm)を得た。これをダイボンドフィルムA〜Gのそれぞれに貼り合わせた後、破断試験を行った。破断試験は、エキスパンド温度0℃、10℃、25℃のそれぞれの条件下において行った。エキスパンド速度は、400mm/秒、エキスパンド量は、6%とした。破断試験の結果、半導体ウェハの中央部100チップについて、ダイボンドフィルムが良好に破断されているチップ数をカウントした。ただし、比較例1については、半導体ウェハにダイボンドフィルムFが貼り付かなかったため、また、ダイボンドフィルムFが脆くて作業性が悪かったため、測定を行えなかった。結果を表2に示す。
