Description
サセプタ1は、図1、図2に示すように、円板状のSiC部材である。サセプタ1は、上面に1または複数の円形の凹部9を有する。本実施の形態では、サセプタ1は、3つの凹部9を有する。この凹部9は、ウェハを収容するための収容部である。サセプタ1の外径は、例えば、300mmから500mmである。サセプタ1の厚みは、例えば、1mmから4mmである。凹部9の内径は、例えば、100mmから300mmである。
サセプタ1は、図3に示すように、第1上面11と第1下面13とを有する第1SiC層3と、第2上面15と第2下面17とを有する第2SiC層5とを備える。第1上面11は、凹凸を有する。第2下面17は、第1上面11に接しており第1上面11の凹凸に対応する凹凸を有する。第2SiC層5は、第2上面15から第2下面17側へと凹状となっている、平坦な底面23を有する凹部9を有する。本実施の形態では、第1上面11の凹凸は、第1上面11の全体的に湾曲した面により形成されている。具体的には、第1上面11は、上方に向けて突出した凸面である。この凸面の突出量は、例えば、50μmから100μmである。第2上面15は、平坦面である。凹部9の底面23は、第2上面15に略平行である。凹部9の深さは、例えば、300μmから500μmである。
図4はサセプタ1の製造方法を示す。
B1=B2×D1/D2
C1=C2×D1/D2
図5(b)は、サセプタ1の第2上面15と、第3下面21を形成するために行う加工量を決定するために、次に決定すべき値を示している。
E2=E1+(J1−K1)/2
F2=F1−(J1−K1)/2
すなわち、上述のように加工量E2とF2を決定することで、図5(c)に示すように、第1距離K2と第2距離J2が同じになる。
本発明の実施の形態は、以上の実施例に限定されることなく、本発明の技術的範囲に属する限り種々の形態をとりうることはいうまでもない。
図7および図8が示すように、比較例におけるサセプタ51は、第1SiC層53と、第2SiC層55と、第3SiC層57と、凹部59と、を備える。凹部59は底面63を有する。底面63には、第1SiC層53と第2SiC層55とで形成される界面65が現れている。
9…凹部、11…第1上面、13…第1下面、15…第2上面、17…第2下面
19…第3上面、21…第3下面、23…底面、27…第1距離、29…第2距離
