Description
内部を真空とすることが可能であり、上部に開閉可能な蓋体を有するチャンバと、
前記チャンバ内に設けられ、円周の軌跡でワークを回転搬送する搬送部と、
前記搬送部により搬送される前記ワークに、スパッタリングにより成膜材料を堆積させて成膜する成膜部と、
前記ワークが通過する側に開口を有し、前記成膜部による成膜が行われる成膜室を形成し、前記成膜材料が飛散したり、前記成膜室内に導入されるガスが流出するのを防ぐシールド部材と、
前記シールド部材を支持し、前記チャンバに対して不動で且つ前記蓋体から独立した支持部と、
を有することを特徴とする。
本発明の実施形態について、図面を参照して具体的に説明する。図1及び図2に示すように、成膜装置Dはチャンバ1を有する。チャンバ1は、略円筒形状の有底の容器である。チャンバ1は、内部を真空とすることが可能であり、上部を開閉可能な蓋体1aを有する。蓋体1aは、円形の板状部材であり、チャンバ1の上部を気密に封止する。また、チャンバ1には排気部2が設けられており、チャンバ1の内部を真空に排気可能になっている。すなわち、チャンバ1は真空容器として機能する。
本実施形態の成膜装置Dの動作を説明する。蓋体1aを開いた状態で、シールド部材9が外周支持部OP、内周支持部IPに搭載される。外周支持部OP、内周支持部IPは、上記のような高さに設定されているので、シールド部材9の下端は、ワークWが通過可能な間隔を空けて支持される。
(1)本実施形態の成膜装置Dは、内部を真空とすることが可能であり、上部に開閉可能な蓋体1aを有するチャンバ1と、チャンバ1内に設けられ、円周の軌跡でワークWを回転搬送する回転テーブル3と、回転テーブル3により搬送されるワークWに、スパッタリングにより成膜材料を堆積させて成膜する成膜部4a~4gと、ワークWが通過する側に開口91を有し、成膜部4a~4gによる成膜が行われる成膜室Sを形成するシールド部材9と、シールド部材9を支持し、チャンバ1に対して不動で且つ蓋体1aから独立した支持部Pと、を有する。
本発明の実施形態は、上記の態様に限定されるものではなく、以下のような態様も含む。なお、上記の態様と同様の構成については、説明を省略する。
(1)図4及び図5に示すように、シールド部材9と支持部Pとの間に、防振材(第1の防振材)30を設けてもよい。つまり、外周壁93aの下端と外周支持部OPとの間、内周壁93bの下端と内周支持部IPとの間に、それぞれ防振材30を挟む。防振材30は、直方体形状、円柱形状、角柱形状等の弾性部材を用いることができる。弾性部材としては、例えば、1×10-3N/mm~400N/mmのばね定数を有する材料を用いることができる。弾性部材の一例は、ゴムである。なお、外周支持部OP、内周支持部IPが比較的広い面でシールド部材9を支持する場合には、シート状の防振材30を用いてもよい。
