Description
ところで、ビームBを高速でブランキング制御するために、ブランキング偏向器212を高周波信号(例えば、1GHz以上の高周波パルス信号)で動作させた場合、電流は、表皮効果によって第1電極231および第2電極232の対向面における表面近傍を流れる。本実施形態において、第1電極231および第2電極232の対向面には、図3(A)および図3(B)に示すように、第1低抵抗膜231_3および第2低抵抗膜232_3が設けられている。本実施形態では、表皮効果による電流が第1低抵抗膜231_3および第2低抵抗膜232_3の全体に流れるように、第1低抵抗膜231_3および第2低抵抗膜232_3の膜厚を設定する。
高周波信号でブランキング制御する場合、表皮効果により、電流のほとんどは、第1および第2低抵抗膜231_3,232_3を流れる。一方、低周波信号(例えば、約1MHzの低周波パルス信号)でブランキング制御する場合、オームの法則に従って、電流は、第1および第2低抵抗膜231_3,232_3並びに第1および第2材料膜231_2, 232_2の両方を流れようとする。
