Abstract
Description
この方法では、ウェーハの表面に対してエッジトリミングを実施した後、ウェーハを反転させて、裏面を研削する。これにより、面取り部が完全に除去されるので、エッジトリミングの深さを均一にする必要が無い。
図1(a)(b)に示すように、貼り合わせウェーハ1は、ウェーハ2と、ウェーハ2を支持するための基板となる支持ウェーハ3とを含んでいる。
ウェーハ2は、円板状に形成されており、表面2aから裏面2bにかけて、円弧状に面取り部4が形成されている。ウェーハ2は、その表面2aにデバイスDを有している。
支持ウェーハ3は、たとえばシリコンを母材とし、比較的に高い剛性を有している。支持ウェーハ3は、ウェーハ2とほぼ同形の円板状に形成されている。また、貼り合わせウェーハ1では、支持ウェーハ3の中心とウェーハ2の中心とが、ほぼ合致している。なお、支持ウェーハ3の母材は、サファイアあるいはガラス等であってもよい。
また、貼り合わせウェーハ1の外周縁7には、ウェーハ2の結晶方位を示すノッチ9が設けられている。
図2に示すように、本測定装置は、貼り合わせウェーハ1を保持して回転する保持テーブル部10、貼り合わせウェーハ1の外周上面の高さを測定する上面高さ測定手段20、および、本測定装置の制御系であるコントローラ30を備えている。
エンコーダ17は、回転軸13の回転角度に対応する数のパルスを出力するように構成されている。
貼り合わせウェーハ1の外周上面は、貼り合わせウェーハ1の外周部分の上面であり、たとえば、貼り合わせウェーハ1のウェーハ2の裏面2bにおける、外周縁7から所定長さだけ内側に入った部分までの範囲、すなわち、外周縁7に沿った所定幅を有する円形の帯状の部分である。貼り合わせウェーハ1の外周上面は、エッジトリミングされるウェーハ2の面取り部4(図1(b)参照)部分を含んでいる。
なお、図4では、本測定装置を、図3に示した矢印a方向から示している。
なお、受光センサー25による高さ測定方法としては、測距反射形光電センサーに関する公知の測定方法を適用することが可能である。
まず、図6に示すように、ユーザによって、貼り合わせウェーハ1が、保持テーブル11の保持面12a上に載置される。その後、図示しない吸引源からの吸引力により、保持面12aに負圧が生じる。保持面12aは、この負圧によって、貼り合わせウェーハ1の支持ウェーハ3の裏面3bを吸引保持する。これにより、貼り合わせウェーハ1が、ウェーハ2の裏面2bを上向きに露出した状態で、保持面12aに吸着保持される。なお、図6では、本測定装置を、図3に示した矢印b方向から示している。
制御手段31は、受光センサー25に受光された反射光に基づいて、測定範囲R内の反射部位の高さを求める。
エッジトリミング装置は、貼り合わせウェーハ1の回転角度の原点であるノッチ9、および、ノッチ9からの貼り合わせウェーハ1の回転角度を、容易に検出することができる。さらに、エッジトリミング装置は、対応データに基づいて、原点からの回転角度に対応する貼り合わせウェーハ1の外周上面の高さを把握することができる。そして、エッジトリミング装置は、把握した外周上面の高さに基づいて、切削ブレードを、貼り合わせウェーハ1の外周上面に対して上下に移動させることができる。これにより、エッジトリミング装置では、貼り合わせウェーハ1の外周上面に対する切削ブレードの切り込み深さを、容易に略一定にすることができる。
また、本実施形態では、貼り合わせウェーハ1は、ウェーハ2と、ウェーハ2を支持する支持ウェーハ3と、貼り合わせ部材の一例である接着部材Jとを含んでいる。これに代えて、貼り合わせウェーハ1は、2枚以上のウェーハ2を貼り合わせることによって形成されてもよい。
