Abstract
Description
多結晶シリコンブロックから切断したホウ素ドープシリコンウェーハは、縁部に亀裂を有する。ウェーハをプラズマチャンバ内に移送する。チャンバを空にし、フッ化カルボニルを0.4mbarの圧力までチャンバ内に導入し、プラズマを開放させる。プラズマ処理の間、当初鋭角だった亀裂は、増殖しないキーホール様の構造へと変形させられる。この時点でウェーハはもはや無用ではなく太陽電池を得るためのさらなる処理(リンでのドーピング、電極の付着など)のために使用可能である。
ホウ素ドープシリコンウェーハをPOCl3と接触させ、960〜1000℃まで加熱してリン化合物をP2O5に変換させる。副反応として、リン−シリカガラス様コーティングが形成される。このガラス様コーティングを除去するために、ウェーハをプラズマ処理チャンバ内に置き、チャンバを真空にし、0.4mbarの圧力が達成されるまで反応器内に無希釈のフッ化カルボニルと導入する。その後プラズマを開放させる。ガラス様のコーティングがエッチングにより除去されると直ちにプロセスを停止させる。
実施例4を反復するが、今度は、20体積%のフッ素、10体積%の窒素および70体積%のアルゴンからなる混合物を適用する。ガラス様コーティングをエッチングにより除去する。
無希釈のフッ化カルボニルでエッチングして反射性を低くしたウェーハをさらに処理して、欧州特許出願公開第A−0542148号明細書で記述されている通りに電極を適用する。銀そして無機結合剤として酸化鉛および二酸化ケイ素を含有するぺーストを、電極構造の所望のパターンにしたがってスクリーン印刷によりウェーハの表側に適用する。裏側には、さらにアルミニウムを含有する類似の電極ペーストを適用する。その後、800℃前後でウェーハを焼成する。次に塩化銀およびチオ硫酸ナトリウムを含む浴中で、パターンをメッキする。これは、特に3頁53行目から5頁23行目までに記述されている通りに行われる。
米国特許第5688415号明細書、第5欄60行目から第9欄4行目までに記述されている通りに大型フラットパネルディスプレイ上でシリコントランジスタを形成させる。例えばインジウムスズ酸化物または酸化ケイ素などの1つ以上の透明電極材料製の被覆フィルムが、ガラス基板に提供される。既定の開口部を有するフォトレジストでコーティングを被覆する。基盤をプラズマチャンバ内にいれ、フォトリトグラフィマスクのパターンを、ガラス基板上のフィルムまで掃引により転写する。その後のステップにおいてエッチングを行なう。このステップでは、60重量%のフッ化カルボニル40重量%のアルゴンの混合物を適用する。過剰エッチングを防ぐために、計算用ハードウェアおよび適切なソフトウェアを用いて、プラズマ滞留時間バージョン位置マップを生成する。
Claims (1)
- プラズマ援用処理でシリコンウェーハから太陽電池を製造する方法であって、フッ素および窒素の混合物、フッ素およびアルゴンの混合物、または、フッ素および窒素およびアルゴンの混合物から成るエッチングガスでウェーハをエッチングするステップを含み、前記ウェーハの表面をエッチングして前記表面を粗面化する、方法。
