Claims (1)
- 側面と上面とを有する3次元構造のデバイスを半導体基板上に製造する為に用いられるイオン注入方法であって、
各面へのイオン注入に先立って、前記上面にブロッキングマスク材料を配置するマスク配置工程と、
第一のエネルギーで前記側面へのイオン注入処理を行う第一のイオン注入工程と、
前記第一のイオン注入工程に引き続き、前記ブロッキングマスク材料を取り除くマスク取り除き工程と、
前記上面へのイオン注入処理に先立って、半導体基板上に照射されるリボン状のイオンビームの広がり角度を計測する計測工程と、
前記上面へのイオン注入処理に先立って、空間電荷効果に起因する前記側面への影響を考慮して、当該角度が所定の範囲内にあるかどうかを判別する判別工程と、
前記判別工程で前記イオンビームの広がり角度が所定範囲内にないと判別されたとき、前記イオンビームの広がり角度が所定範囲内となるように補正する角度補正工程と、
前記判別工程にて、前記イオンビームの広がり角度が所定範囲内にあると判別された後、前記第一のエネルギーよりも低い第二のエネルギーで前記側面と同程度のイオン注入深さとなるように前記上面へのイオン注入処理を行う第二のイオン注入工程とを有していることを特徴とするイオン注入方法。
