Description
し、熱処理された半導体ウエハをウエハキャリアに収納する。この一連の搬送動作の中に、枚葉型のロボットアームによってウエハキャリアとウエハボート間で半導体ウエハを搬送する動作と、半導体ウエハが搭載されたウエハボートを熱処理炉内で上下方向に移動させる動作を含んでいる。
図1は、本発明に係る実施の形態のウエハボートを使用する縦型バッチ式熱処理装置100の構成を示す概略図である。図1に示す用に縦型バッチ式熱処理装置100は、複数枚のSiCウエハ6が収容可能なウエハキャリア1を装置外部との間で出し入れするキャリア室70と、キャリア室70に連通し、複数枚のSiCウエハ6を、それぞれの主面が上下で対向するように搭載する石英のウエハボート3が格納されるボート室80と、ボート室80の上方に設けられ、ウエハボート3ごと複数枚のSiCウエハ6に対して熱処理を行う熱処理炉5が配置された熱処理室90とを備えている。石英を用いることで、耐熱性に優れたウエハボート3を得ることができる。なお、ウエハボート3の材質としてはサファイアなども考えられる。
熱処理炉5内に挿入されるようにボートエレベーター4を上昇させることで載置台41が開口部を塞ぎ、熱処理炉5は密閉されることとなる。
