Description
ン24と間隙の幅は比較的狭いため、磁束密度が高くなる。単一の閉鎖軌道に沿って磁場の分布が閉鎖形状となっているため、端部からのプラズマの漏れが防止される。
た保持具セクション128と、関連する帯状ターゲット124上の関連するヨークセクションを部分的に支持する。これにより、可撓性マグネトロンは非平面のターゲットをたどり、かつその形状に沿うことが可能となる。
単列であり、内部の磁石列は全て二列である。図8の一次設計により、褶曲蛇行型磁石の先頭と尾部との間に二列構造接合部196が形成される。急コーナー部に隣接して、湾曲する間隙の凸側の急端部193、194に関連したある極性の磁石の数は、湾曲する間隙の凹側の外側湾曲縁部上に配置された、極性が反対の磁石の数より著しく少ない。この磁石の不均衡により、プラズマ軌道は急端部193、194に向かって押し出される傾向がある。プラズマ軌道の中央線のこのズレは、スパッタターゲットの前方の磁場が水平、つまりターゲットに平行な場合に軌道中心線が生じやすいということを理解することで説明し得る。ある磁極がもう一方の磁極より弱い場合、磁場分布の平坦部は弱いほうの磁極へと押し出される。
ット282に電力を供給し、スパッタ作用ガスのプラズマを励起する。
