description PROBLEM TO BE SOLVED: To supply a droplet generator with target material and remove unused target material without requiring excessive downtime.SOLUTION: An EUV light source target material handling system is disclosed which may comprise a droplet generator having a target material reservoir which may be replenished with the target material while a nozzle portion of the droplet generator is maintained at a temperature. Also disclosed is a system for selectively draining the spent target material.SELECTED DRAWING: Figure 3 【課題】過剰な時間のロスを必要とせず液滴ジェネレータにターゲット材料を供給しかつ未使用のターゲット材料を除去する。【解決手段】液滴ジェネレータのノズル部分の温度が維持されている間にターゲット材料が補充され得るターゲット材料リザーバを有する液滴ジェネレータを備え得るEUV光源ターゲット材料取扱システムが開示される。選択的に使用済みターゲット材料を排出するためのシステムも開示される。【選択図】図3
