Qualitative and quantitative evaluation of metallic impurities in non-alkali glass.
TOF-SIMS, D-SIMS: Secondary Ion Mass Spectrometry
In semiconductor manufacturing processes, the contamination of impurities can lead to a decrease in characteristics and manufacturing yield, making the prompt identification and quantification of impurity elements crucial. At MST, we qualitatively analyze impurity elements using TOF-SIMS (Static-SIMS) and quantitatively measure the detected elements in the depth direction using D-SIMS (Dynamic-SIMS), enabling the evaluation of impurities within devices. This document presents a case study of measuring metal impurities in alkali-free glass.
