Abstract
Description
近年、半導体素子は、高性能化に伴い微細配線を必要とする場合がある。成膜工程は、例えば化学気相蒸着(Chemical Vapor Deposition:CVD)法や物理気相蒸着(Physical Vapor Deposition:PVD)法等により実施される。また、成膜工程はスパッタリングや原子層堆積(Atomic Layer Deposition:ALD)法等を用いて実施される。これらの方法は、真空を利用する。例えば、スパッタリングは、スパッタリングターゲットにイオンを衝突させることにより、ターゲット表面から弾き飛ばされた原子を基材上に堆積させる。
基材としてアルミナ基板を用意した。基板表面の表面粗さRaが1.0μmになるように研磨加工を施した。次に、純度99.5質量%の金属イットリウムターゲットを用意した。アルミナ基板上に、金属イットリウム膜を形成する工程と酸化工程を繰り返して多結晶酸化イットリウムを含む膜を形成した。また、実施例1ないし3は金属イットリウム膜の厚さは3~7nmの範囲とした。金属イットリウム膜形成工程と酸化工程とを繰り返すことにより、表1に示す厚さを有する部品1を作製した。
