[Analysis Case] Simultaneous Qualitative Analysis of Inorganic and Organic Contaminants/Adhesives on Wafers
Simultaneous measurement of inorganic and organic components in minute specific areas.
TOF-SIMS has features such as simultaneous evaluation of organic and inorganic materials, capability for micro-area analysis, and high sensitivity for analyzing the very surface, making it effective for residue investigation in cleaning processes. An example is presented where pure water was dried on a silicon wafer. Optical microscopy only reveals slight point-like foreign substances and cloudiness. However, the results measured by TOF-SIMS showed that in the contaminated areas, organic components such as hydrocarbons, PDMS, and amides, which tend to adsorb naturally, were aggregated.
