Description
ウェハ載置面を備えたセラミック部材と、
前記セラミック部材に埋設され前記ウェハ載置面に沿う形状の埋設電極と、
前記セラミック部材のうち前記ウェハ載置面とは反対側の面から前記埋設電極に達するように埋設された金属製の接続部材と、
前記接続部材のうち外部に露出している面に接合層を介して接合された金属製の外部通電部材と、
を備えた接合構造体であって、
前記接続部材は、円柱部材であり、直径Dが3.5〜5mm、前記埋設電極に接している円形面と円柱側面とのコーナー部分の曲率半径Rが0.3〜1.5mm、比率R/Dが0.09以上のものである。
ウェハ載置面を備えたセラミック部材と、
前記セラミック部材に埋設され前記ウェハ載置面に沿う形状の埋設電極と、
前記セラミック部材のうち前記ウェハ載置面とは反対側の面から前記埋設電極に達するように埋設された金属製の接続部材と、
前記接続部材のうち外部に露出している面に接合層を介して接合された金属製の外部通電部材と、
を備えた接合構造体であって、
前記接続部材は、円柱部材であり、直径Dが3.5〜5mm、
前記埋設電極に接している円形面と円柱側面とのコーナー部分は短径F、長径Gの楕円形状であり、前記短径F及び前記長径Gが0.3〜1.5mm、比率F/D及び比率G/Dが0.09以上のものである。
図2の製造手順にしたがい、上述したセラミックヒータ10のサンプルを10種類製造した(試験例1〜9)。まず、窒化アルミニウム粉末にヒータエレメント14と円柱体116とを埋設し、一軸加圧成形することによって成形体112を作製した。ヒータエレメント14としては、モリブデン製の金網を使用した。この金網は、直径0.12mmのモリブデン線を、1インチあたり50本の密度で編んだものを使用した。円柱体116としては、粒径1〜100μmのモリブデン粉末を円柱状に成形し、ヒータエレメント14に接する円形面と円柱側面とのコーナー部分116bの曲率半径Rが所定の値になるように加工したものを使用した。この成形体112を金型に入れ、カーボンフォイル内に密封し、ホットプレス法で焼成することにより、セラミック部材12を得た。焼成は、温度1950℃、圧力200kgf/cm2で2時間保持することにより行った。このセラミック部材12を直径200mm、厚さ8mmになるように加工した。
室温下、セラミック部材12を固定し、外部通電部材18のフランジを把持して垂直に引っ張り上げ、接続部材16と外部通電部材18との接合が破断したときの荷重を測定し、その荷重を引張破断強度とした。測定には、引張強度試験機(島津製作所製、オートグラフ)を使用した。
成形体112を焼結させてセラミック部材12を製造した直後にセラミック部材12にクラックが発生したか否かを調べ、クラックが発生していたものについて製造時破損ありと判定した。
真空下、セラミックヒータ10を700℃まで加熱したあと室温まで降温し、その状態でセラミック部材12にクラックが発生したか否かを調べ、クラックが発生したものについてセラミック破損ありと判定した。ちなみに、セラミック部材12の材質(AlN)と接続部材16の材質(Mo)との熱膨張係数の僅かな違いにより熱応力が発生するが、コーナー部分16bではその熱応力が集中しやすいため、コーナー部分16bを起点とするクラックがセラミック部材12に発生しやすい。
試験例10〜13では、円柱体116として、ヒータエレメント14に接する円形面と円柱側面とのコーナー部分116bを楕円形になるように加工したものを使用した以外は、試験例1〜9と同様にセラミックヒータ10を製造した。試験例10〜13の接続部材16の直径D、コーナー部分の楕円の短径F、長径G、比率F/D,比率G/Dの各値を表2に示す。なお、接続部材16の高さは、一律3mmとした。また、楕円の短径方向は接続部材16の高さ方向(図4で上下方向)、楕円の長径方向は接続部材16の幅方向(図4で左右方向)とした。試験例10〜13につき、上述した各評価試験を行った。その結果を表2に示す。
