208HR系統為得到高分辨鍍膜效果提供了多種配置選擇,可配備標準的旋片泵或提供干凈真空的無油渦旋式真空泵,標配的208HR包含Cr 和 Pt/Pd靶。
真空系統:
超高分辨208HR鍍膜系統是現在針對場發射電鏡非導電樣品鍍膜處理以及高性能電極薄膜制備的的解決方案。為了減小噴鍍顆粒尺寸對成像分辨率影響,208HR提供一套全系列的鍍膜靶材材料和的膜厚鍍層控制條件,以達到無顆粒鍍膜效果。而為了更小優化非導電樣品表面充電的效果,208HR的特殊樣品臺設計和大范圍的操作壓力提供了高精度的鍍膜一致性和統一性。 高低樣品室的配置也提供了更為方便的工作距離調整。
Cressington 208HR High Resolution Sputter Coater
The 208HR High Resolution Sputter Coaters from Cressington offer real solutions to the problems encountered when coating difficult samples for high resolution FESEM imaging. High resolution FESEM applications need extremely thin, grain-free, uniform coatings to eliminate charging and to improve contrast on low density materials.
In order to minimize the effects of grain size the 208HR offers a full range of coating materials and gives unprecedented control over thickness and deposition conditions. The 208HR Turbo Pumped High Vacuum System offers a wide range of operating pressures allowing precise control of both uniformity and conformity of the coating, minimizing charging effects. The HIGH / LOW chamber configuration allows easy adjustment of the distance from target to sample.
