At Corning, we have been establishing protocols for ToF-SIMS characterization of Corning-relevant materials including glass, ceramics and organic coatings. Certain processes that are used to manufacture glass, such as ion-exchange, and glass reforming processes require a deep knowledge and understanding of glass surface chemistry. Furthermore, glass aging and durability are also significantly affected by glass surface compositions. Here several examples of where ToF-SIMS has given invaluable information to help better understand glass behaviour will be presented. Discussions of common glass degradation products and chemistries will be reviewed. Finally, the role of organic characterization in a glass company will be demonstrated, as it plays a large role in understanding of contamination problems, and can provide both qualitative and in many cases quantitative assessments of organic components on surfaces, in films, and at interfaces. An example of one such application is shown below in Figure 1, which shows the 3-D isosurface representation of a fiber containing two thick polymer overlayers (30 ┬Ám each). This data was used to assess the chemistries throughout the film as well as at the interfaces.
