Claims (4)
- 複数のデバイスが形成されたデバイス領域と該デバイス領域を囲む外周余剰領域とを表面側に備えたウェーハの加工方法であって、
ウェーハよりも直径の小さい研削ホイールでウェーハの該デバイス領域に対応する裏面側を研削し、該デバイス領域に対応する第1部分と該第1部分を囲み該第1部分よりも厚く裏面側に突出する環状の第2部分とを形成する第1研削ステップと、
該第1研削ステップで使用された研削ホイールとは異なる研削ホイールで該第1部分の一部を更に研削し、該第1部分の裏面よりも滑らかな底を持つ凹部を形成する第2研削ステップと、を含み、
該第1研削ステップでは、該第1部分の該裏面と該第2部分の内側の側面とが、45°より大きく75°より小さい角度をなすように該研削ホイールとウェーハとを相対的に移動させることを特徴とするウェーハの加工方法。 - 該第2研削ステップでは、該研削ホイールとウェーハとを鉛直方向にのみ相対的に移動させることを特徴とする請求項1に記載のウェーハの加工方法。
- 該第2研削ステップでは、該研削ホイールとウェーハとを水平方向及び鉛直方向から傾斜した方向に沿って相対的に移動させることを特徴とする請求項1に記載のウェーハの加工方法。
- 該第1研削ステップでは、該第1部分の裏面と該第2部分の内側の側面とが、55°以上70°以下の角度をなすように該研削ホイールとウェーハとを相対的に移動させることを特徴とする請求項1から請求項3のいずれかに記載のウェーハの加工方法。
