Description
超小型部品のアクティブ部分を支持する基板を犠牲材料で覆う段階。この犠牲材料は、超小型部品カバーの型材として働く。
空洞を画定するカバーを形成するように、密閉材料を犠牲材料上に堆積させる段階。
密閉材料中に1つまたは複数の孔を開ける段階。
孔を通して犠牲材料を除去する段階。
ゲッター材料を、それが空洞内側に露出されて孔を全体的または部分的にふさぐように、カバー上に堆積させる段階。
S=(P×V)/(a×C)
ただし、aはゲッター材料の活性化レベル、Cはゲッター材料のポンプ容量で単位がPa/cm3/cm-2である。チタンの理論上のポンプ容量は非常に高く、5.2×104Pa/cm3/mg-1であり、これは1マイクロメートルの厚さでは2.7×104Pa/cm3/mg-1になる。
S=[6.7×10-1×(200×10-4)2×4×10-4]/0.5×133.3
