Abstract
【解決手段】 基板表面上の所定位置に触媒金属ドットパターンを配設し、ポリシランガスの300℃以下の温度でのCVDによって所定の触媒金属ドット間にシリコンナノワイヤーを架橋成長させる。
【選択図】図4
Description
シリコンナノワイヤーを成長、位置制御するために、シリコン基板上に触媒金属粒子のパターニングが必要である。まず、SOI(Silicon On Insurator)基板を用いてSiO2上に図1aの平面図のように、厚さ2μm、2μm角のSi単結晶ドットを約15μm間隔でエッチングにより作製する。続いてスパッタリングにより金を約2nmコーティングする。さらに、希釈フッ酸によりSiO2層を取り除くと、金粒子に覆われたシリコン角柱のパターンが得られる(図1b)。ここで、図1(a)(b)での符号は次のものを示している。
<実施例2>
シリコン基板上に金を約2nm厚さでスパッタコーティングし、約15μm幅の細い傷を入れる。その後、実施例2と同様な条件によりシリコンナノワイヤーを形成させる。図4に示すようにシリコンナノワイヤーによる架橋が行われていることがわかる。なお図4では反応ガスは右上から左下へ流しており、ほぼ流れの方向に沿ってワイヤーが形成される。
