Description
ここで述べた検出領域とは、捕集電極1でイオンビームIBを受光する領域であり、換言すればイオンビームIBから見えている捕集電極1の部位に相当する。
なお、マスク4は接地されており、2次電子抑制電極3には接地電位を基準にして負の電圧が印加されている。
また、図2(B)のように、各捕集電極1に接続された切換え回路Sの1つをオン状態とし、残りをオフ状態にしておけば、任意の捕集電極1で検出されたビーム電流を計測することが可能となる。さらに、切換え回路Sのオン状態を順番に切り替え、各捕集電極1を通じてビーム電流の計測を行うことで、ビーム電流分布を知ることが出来る。
このイオン注入装置IMにおいて、ビーム電流計測器BDはイオンビームIBの輸送経路や処理室16に配置されている。
また、荷電粒子ビームの形状は、スポット状の形状に限られず、一方向に長いシート状のビームやリボンビームであってもよい。
