Abstract
Description
本実施形態では、SiC膜に自立可能な強度を持たせることでSiC膜単体構造体10を構成している。図1に示す形態は、半導体ウェハ製造に用いられる治具としてのボートであるが、これは、実施形態に係るSiC膜単体構造体10が平面構造だけでなく、凹凸を有する形態にも適用可能であることを示すものであり、形態や用途を限定するものではない。
このような構成の本実施形態に係るSiC膜単体構造体10の製造工程について、図2を参照して説明する。まず、図2(A)に示すように、所望する構造体の形態と逆の凹凸を持つ基材30、すなわち雌型の基材30を製作する。基材30は、表面にも微小な気孔が形成されることとなる多孔質部材、例えばグラファイト等を構成材料として製作すれば良い。なお、基材30の下端側には、マスキング32を施し、基準面への設置が可能な状態とする。
上記のようにして基材30の除去を行うことで、図2(F)に示すように、SiC膜単体構造体10が形成される。
このように、実施形態に係るSiC膜単体構造体10は、機能面12を構成する第1SiC層20を基準として、順次積層型SiC層22を積層することで構成されている。このため、SiC膜単体構造体10の機能面12は、精度良く基材30の形状に沿ったものとなる。また、形状精度に膜厚の影響を受けることがないため、SiC膜単体構造体10は、膜厚の増加による強度の向上を図ることも可能となる。
上述したように、本実施形態に係るSiC膜単体構造体10は、機能面12が膜厚の影響を受けることが無い。このため、図3に示すように、SiCにより構成される膜の厚みを厚くすることで、非機能面14に形成された溝の幅が狭められたとしても、機能面12は所望する精度を保つことができる。よって、重量物を配置、あるいは保持する場合でも工作精度の高いSiC膜単体構造体10を提供することが可能となる。
