Abstract
Description
本明細書に開示される実施形態は、一般に、処理チャンバ内で基板上に膜を製造するための装置に係り、より詳細には、プラズマ処理用途で不均一なガスフローを提供するために処理チャンバ内で使用されるフレームに関する。
液晶ディスプレイ又はフラットパネルは、アクティブマトリクスディスプレイ(例えば、コンピュータ、テレビ及びその他のモニタ等)に一般に使用されている。プラズマ強化化学気相堆積(PECVD)は、基板(例えば、半導体ウェハ又はフラットパネルディスプレイのための透明基板等)上に薄膜を堆積させるために使用される。PECVDは、一般に、前駆体ガス又はガス混合物を基板を含む真空チャンバに導入することによって達成される。前駆体ガス又はガス混合物は、典型的には、処理チャンバの上部近くに配置された分配プレートを介して下方に向けられる。処理チャンバ内の前駆体ガス又はガス混合物は、電極に結合された1以上の電源から電力(例えば、高周波(RF)電力)を処理チャンバ内の電極に印加することによって、プラズマにエネルギー化(例えば、励起)される。励起されたガス又はガス混合物は、反応して基板の表面上に材料の層を形成する。この層は、例えば、パッシベーション層、ゲート絶縁体、バッファ層、及び/又はエッチングストップ層であるかもしれない。この層はより大きな構造の一部(例えば、ディスプレイデバイスで用いられる薄膜トランジスタ(TFT)又はアクティブマトリクス有機発光ダイオード(AMOLED))であってもよい。
