Abstract
Description
構造がない200mmの平坦なシリコンウエハーを、Secon Semiconductor Equipment GmbH,Austria製のマイクロ波プラズマエッチャーでドライエッチングする。
ウエハーは300℃の温度に維持されたエッチングチャンバー及びヒーターの中に置く。熱的エッチング、すなわちプラズマ源の電源を切った状態でのエッチングは、20体積%のF2と、200ppmvのHFと、100体積%までの残部であるN2とからなる気体混合物を用いて、大気圧(755Torr)で20sccmの流速で開始する。熱的エッチング工程は60秒間行う。対照実験は、1ppm未満のHF含量である20体積%のF2と80体積%のN2とからなる超高純度の気体混合物を使用して上に記載したのと同じパラメーターを使用して行う。
実施例1で概説した手順に従って処理したシリコンウエハーを、欧州特許出願公開第A−0542148号明細書に記載の通りに電極を取り付けるために更に処理する。銀と、無機バインダーとしての酸化鉛及び二酸化ケイ素とを含むペーストを、望ましい電極構造のパターンに従ってスクリーン印刷することによってウエハーの表面に塗布する。裏面には、アルミニウムを更に含む同様の電極ペーストを塗布する。その後、ウエハーを約800℃で焼き付ける。その後パターンを塩化銀及びチオ硫酸ナトリウムを含む浴の中でめっきする。
