Abstract
Description
・半導体基板の表面にパターン化されたエッチングマスクを設けるステップと、
・前記半導体基板の表面に略垂直な方向においてナノワイヤを形成するよう前記半導体基板をエッチングするステップと、
を有するナノワイヤ製造方法に関する。
11(1993), 2532-2537”により知られている。この既知の方法では、eビームリソグラフィによってエッチングマスクによりパターンが規定される。このパターンは、反応性イオンエッチングにより半導体基板に転写される。このパターンは、エッチングマスクによりエッチングに対して保護されるべき隔離領域を規定するので、半導体基板にナノワイヤが形成される。これらナノワイヤは、60nmの直径と10μmの長さを有する。ナノワイヤの外殻は、その後800℃へ加熱することにより酸化させられる。そしてこの外殻は、HF処理槽におけるエッチングにより除去され、直径6ないし15nmのナノワイヤが残る。
