Description
本願は、米国特許法第120条に基づき、米国特許出願第11/512,853号(2006年8月30日出願)の利益を主張している。米国特許出願第11/512,853号は参照により本明細書に援用される。
本発明に用いられるシーメンス反応器は、米国特許第2,999,735号、同第3,011,877号、同第3,862,020号、又は同第3,961,003号に開示されているシーメンス反応器等の従来のシーメンス反応器であってよい。例えば、シーメンス反応器の操作は以下の通りに実施され得る。多結晶シリコンシードロッドをシーメンス反応器内に垂直で互いに平行となるように配置する。これらのシードロッドを2つ以上互いにブリッジにより連結することによって、U字ロッドを形成してもよい。700℃〜1400℃、代替的には1000℃〜1200℃、代替的には1100℃〜1150℃の範囲の温度に達するまでU字ロッドを加熱する。シーメンス反応器は、13kPa(2psig)〜3450kPa(500psig)、代替的には6kPa(1psig)〜1380kPa(200psig)、代替的には100kPa(1bar)〜690kPa(100psig)の範囲の圧力下で操作し得る。
本発明に用いられる流動床反応器は、米国特許第5,077,028号に開示されている流動床反応器等の従来の流動床反応器であってもよい。例えば、流動床反応器の操作は以下の通りに実施され得る。シリコンのシード粒子を流動床反応器内に配置し、流動化させる。シード粒子の供給源は当該技術分野において既知である。例えば、シード粒子は、顆粒状の多結晶シリコンの機械的磨耗によって、又はシーメンス反応器内で生成された多結晶シリコンを粉砕することによって得ることができる。床を流動化するのに用いられるガスは、シーメンス反応器からのベントガス流;水素、アルゴン、ヘリウム、窒素等の希釈ガス;又はこれらの組合せを含んでいてもよい。シリコンはシード粒子の表面上に析出してシード粒子の直径を増大させる。得られるビーズ状の生成物を流動床から取り出し、より多くのシード粒子を導入してもよい。
流動床反応器からのベントガス流は任意の従来の手段によって回収され得る。流動床反応器からのベントガス流は従来の設備を用いて冷却してもよい。微細なシリコン粉末は、接触型コンデンサ、焼結金属ブローバック濾過アセンブリ、又はサイクロンとフィルタアセンブリとの組合せ等の従来の設備を用いて除去してもよい。
