を含み、形成された層が、少なくとも部分的に多形であり且つ大部分がシリコン−ゲルマニウムからなる層が存在するように、ゲルマニウムを含有するために、該配合物が追加的に少なくとも1つのゲルマニウム化合物を含有することを特徴とする。
比較例1
≦0.5ppmのO2および≦0.5ppmのH2Oを有するアルゴン雰囲気(グローブボックス)中で、10gのシクロペンタシランを、開放容器内で、UVランプ(波長254nm、出力15ワット)を用い、6cmの間隔で15分間照射する。その際、希薄なシランがより濃厚になる。ゲル透過クロマトグラフィー(GPC)を用い、ポリスチレン検量線を利用して、Mw=2400g/molの高分子成分の質量平均分子量を測定する。さらに、該混合物はまだモノマーのシクロペンタシランの残分を含有している。該混合物を3部のトルエンで希釈し、且つ、スピンコーターを用いて、予備洗浄された石英薄片(3cm×3cm)に塗布する。その後、ヒータープレートを用いて、該層を500℃に加熱する。暗色のシリコン層が生じる。この層を、オーブン内で、不活性ガス下、750℃で30分間、後温度処理する。
比較例1を繰り返し、且つ、UV照射によって製造された、Mw=2400g/molの高分子成分の質量平均分子量を有するオリゴマーのシクロペンタシランと、モノマーのシクロペンタシランとの混合物に、希釈の際、トルエンと共に、トリ(o−トリル)燐をドーピング剤として添加する。溶液を再度、スピンコーターを用いて、予備洗浄された石英薄片(3cm×3cm)に塗布し、且つ、ヒータープレートを用いて、該層を500℃に加熱する。暗色のn型ドープシリコン層が生じる。この層を、オーブン内で、不活性ガス下、750℃で30分間、後温度処理する。
