Claims (6)
- ウェハを粗研削する粗研削ステージと、前記ウェハを精研削する精研削ステージと、前記ウェハを移送する移送手段と、を備える研削装置であって、
前記ウェハを研削する砥石に干渉しない位置で且つ前記ウェハの中心の移送軌跡上に測定地点が固定され、前記ウェハを前記粗研削ステージから前記精研削ステージに移送する間に前記ウェハの厚みを測定する厚み測定手段と、
該厚み測定手段の測定値に基づいて精研削前のウェハの厚みを算出して精研削後の目標厚みを補正する制御手段と、
を備えていることを特徴とする研削装置。 - 前記制御手段は、前記厚み測定手段の測定値に基づいて精研削前のウェハ全面の平均厚みを算出して精研削後の目標厚みを補正することを特徴とする請求項1記載の研削装置。
- 前記ウェハを保持するウェハチャックは、前記厚み測定手段が前記ウェハの厚みを測定する際に前記ウェハを回転させることを特徴とする請求項1又は2記載の研削装置。
- 前記厚み測定手段は、分光干渉式厚み測定器であることを特徴とする請求項1乃至3の何れか1項記載の研削装置。
- 前記厚み測定手段は、前記移送手段を跨ぐように設けられたコラムに取り付けられていることを特徴とする請求項1乃至4の何れか1項記載の研削装置。
- 前記精研削ステージ内で前記ウェハの任意の1点の厚みを測定する仕上がり厚み測定手段をさらに備え、
前記制御手段は、前記仕上がり厚み測定手段が測定した精研削前後のウェハの任意の1点の厚みの差から前記厚み測定手段が測定した精研削前後のウェハ全面の平均厚みの差を減じて得られるウェハの形状変化に伴う補正値に基づいて、前記精研削後の目標厚みを再補正することを特徴とする請求項1乃至5の何れか1項記載の研削装置。
