NanoCalc 反射膜厚測量系統(tǒng)
 |
薄膜的光學特性主要有反射和干涉。NanoCalc薄膜反射測量系統(tǒng)可以用來進行10nm -250um的膜厚分析測量，對單層膜的分辨率為0.1nm。根據(jù)測量軟件的不同，在1秒鐘內(nèi)可以分析單層或多達到10層的膜厚。 |
產(chǎn)品特點
- 可分析單層或多層薄膜；
- 分辨率達0.1nm；
- 適合于在線監(jiān)測；
使用原理
常用的兩種測量薄膜的特性的方法為光學反射和投射測量、橢圓光度法測量。NanoCalc利用反射原理，通過測量寬光譜范圍內(nèi)的反射率曲線來進行膜厚測量。
查找n和k值
可以進行多達十層的薄膜測量，薄膜和基體材質(zhì)可以是金屬、電介質(zhì)、無定形材料或硅晶等。NanoCalc軟件包含了大多數(shù)材料的n和k值數(shù)據(jù)庫，用戶也可以自己添加和編輯。
