上述した実施形態の半導体製造装置用部材10を、Al2O3製の上部プレート20及び下部プレート40と、SiSiCTi製の中間プレート30を用意して、上述した製造方法により製造した。Al2O3の40~570℃の線熱膨張係数は7.7×10-6/K、SiSiCTiの40~570℃の線熱膨張係数は7.8×10-6/Kであった。第1及び第2金属接合材301,302としてはAl-Si-Mg系接合材を用い、TCBにより上部プレート20と中間プレート30と下部プレート40とを接合した。上部プレート20の厚みは、接合前に2mmになるように調整した。なお、誘電体層28の厚みとウエハ載置面22から抵抗発熱体26までの距離は、すべての実験例で同じ値とした。中間プレート30の厚み及び下部プレート40の厚みは、接合前に、それぞれ15mm、8mmになるように調整した。その結果、得られた半導体製造装置用部材10は、凹形状のウエハ載置面22を有し、ウエハ載置面122の平面度(ウエハ載置面22の最大高さと最小高さとの差)は0.06mmであった。
