Description
FIB鏡筒と、前記FIB鏡筒と略直角に配置されたSEM鏡筒と、試料を載置する試料台と、前記試料から発生する二次粒子を検出する検出器と、前記検出器の検出信号からFIB像とSEM像を形成する観察像形成部と、前記FIB像内の前記試料の左右の向きと前記SEM像内の前記試料の左右の向きが同じである前記FIB像と前記SEM像を表示する表示部と、FIB照射による観察面形成と前記観察面のSEM像取得とを繰り返すことで取得した複数のSEM像の左右の向きを反転させ、反転させたSEM像から三次元像を形成する三次元像形成部と、を有する複合荷電粒子ビーム装置を用いる。
本実施形態の複合荷電粒子ビーム装置は、図1に示すように、FIB鏡筒1と、SEM鏡筒2と、試料ステージ3と、二次電子検出器5と、透過電子検出器6を備えている。FIB鏡筒1とSEM鏡筒2は、それぞれのビーム照射軸が略垂直に交差するように配置されている。そして、試料ステージ3に固定された試料4近傍でそれぞれのビーム照射軸が交差するように配置されている。これにより、FIB鏡筒1から照射したイオンビームにより加工した加工面に対し、SEM鏡筒2から電子ビームを略垂直に照射しSEM観察することができる。
また、ビーム走査制御部11は、FIB鏡筒1やSEM鏡筒2から照射するイオンビームや電子ビームの走査方向を制御する。
また、像形成部8で形成された複数のSEM像から三次元像を形成する三次元像形成部15を備えている。
試料の観察像を表示する本願発明の実施形態について説明する。図2(a)は、上述した複合荷電粒子ビーム装置における薄片試料24に対するイオンビーム21と電子ビーム22の照射方向を説明する図である。
SEM像31は、SEM像のX軸方向32が試料24の座標系のZ軸方向27の逆方向に、SEM像のY軸方向33が薄片試料24の座標系のX軸方向25の逆方向になるように表示する。
三次元像を構築する本願発明の実施形態について説明する。図3(a)に示すようにイオンビーム21により、試料24をスライス加工し、露出した面をSEM観察する。スライスされた面のSEM像とスライス面と次のスライス面の間隔から、SEM像をスライス間隔に対応した間隔で並べることで三次元像を構築する。
