Description
本発明の第1の実施形態に係るプラズマ処理装置10は、図1に示すように、処理基板を装着するアノード電極11と、アノード電極11に対向する面に開口部が設けられた貫通孔120を有するカソード電極12と、アノード電極11とカソード電極12間にプロセスガス100を導入するガス供給装置13と、アノード電極11とカソード電極12間に交流電力を供給して、アノード電極11とカソード電極12間においてプロセスガス100をプラズマ状態にする交流電源14とを備える。図1に示したようにアノード電極11とカソード電極12は平板型であり、プラズマ処理装置10は容量結合型プラズマを利用したものである。容量結合方式の電極間の距離は概略均一であることが望ましい。
a=2b+c ・・・(1)
式(1)において、長さcは、貫通孔120内部のシース領域を除いた領域の直径方向の距離である。貫通孔120の直径dは、以下の式(2)で表される:
d=a+2×λd=2b+c+2×λd ・・・(2)
c=0の場合、十分な運動エネルギーを持った電子の移動空間が確保できず、貫通孔120内部に十分なプラズマ生成空間が確保されないことになる。
λd=7.4×103×(Te/ne)1/2 ・・・(3)
図13に、デバイ長λdの計算値の例を示す。ここでは、一般的な高密度グロー放電プラズマの電子温度と電子密度を用いてデバイ長λdを算出した。なお、ガス分子の平均自由工程λgは式(4)、電子の平均自由工程λeは式(5)でそれぞれ表される:
λg=3.11×10-24×T4/(P×D) ・・・(4)
λe=λg×4×21/2 ・・・(5)
式(4)で、Tは雰囲気温度(K)、Pは圧力(Pa)、Dはガス分子の直径(m)である。
図14に、アノード電極11が1つの場合におけるプラズマ処理装置10の例を示す。図14に示すようにカソード電極12の片側の表面にのみプラズマを励起する場合には、カソード電極12のプラズマを励起しない面から距離kの位置にカソード背板121を配置する。このとき、カソード電極12とカソード背板121間にプラズマが発生しないように、k<b(b:電子の平均自由工程)であるように距離kを設定する。このとき、カソード電極12とカソード背板121に交流電源14から交流電力が供給される。なお、アノード電極11とカソード電極12間、及びカソード電極12とカソード背板121間に、プロセスガス100が導入される。
プラズマ処理装置10が、複数のカソード電極12を有する例を図15に示す。図15に示したプラズマ処理装置10では、アノード電極11とカソード電極12が交互に配置され、且つ、最も外側にはアノード電極11が配置されている。このため、アノード電極11の枚数はカソード電極12よりも1枚多い。図15ではカソード電極12が3枚である例を示したが、カソード電極12の枚数が3枚に限られないことはもちろんである。
図1に示したプラズマ処理装置10は、プラズマ化学気相成長(CVD)装置、プラズマエッチング装置、プラズマアッシング装置などに適用可能である。
