Description
Journal of Vacuum Science and Technology B, Vol.21, No.2, pp.655-659.Mar/Apr 2003
なお、aはマスクエッジ52の突出量、bはマスクエッジ52の突出幅である。1式に従うと、エッジラフネス量が大きくなるとエッジラフネス部が粗くなることになる。
−−−−2式
また、前記エッジラフネストリミング量32を得るに要するエッジラフネストリミング時間38は式3で表すことができる。
−−−−3式
一方、マスク本体部トリミング量は図7に示すようにトリミング時間に比例する。このため4式が成立する。
ここでKは、図7に示す直線の傾きでマスク本体のトリミングレートである。なお、Kもラジカル量とイオン量の関数である。
図8は、プラズマ発光のスペクトルを示す図である。前記ラジカル量あるいはイオン量はプラズマモニタとして発光分光器を用いた場合には、図8に示すようなプラズマ発光スペクトルから計算できる。この発光スペクトルは、それぞれのラジカルあるいはイオンが発する固有の波長に対応するピークを有しており、このピークの高さをもとにラジカルあるいはイオンの量を測定することができる。また、発光スペクトルは多くのラジカルの情報を含み、またトリミングに寄与するラジカルも単一のラジカルではないため、複数のピークの高さを演算した値をトリミングに寄与するラジカル量あるいはイオン量とすることができる。
