Abstract
Description
本出願は、2018年12月22日に出願され、「Method and System of Reducing Charged Particle Beam Write Time」と題された、米国非仮特許出願第16/231,447号の利益を主張し、これは、あらゆる目的のために参照により援用される。
いくつかの実施形態では、本来であれば後方散乱が低い領域に人工バックグラウンド露光量を導入することで、画素またはショットの露光量が減少するため、全体的な描画時間が減少する。結果としてPEC後に、画素またはショットの露光量が低くなり、マスクまたはマスクセクションについての画素またはショットの露光量の最大値は減少し、ステージの移動速度は増加することで、全体的な描画時間は有意に減少する。
