SiOH+ / Si+ Data Collected from Display Glass Using ToF-SIMS
Flat panel displays are produced on engineered glass substrates known as display glass. The surface composition of display glass affects physical behaviors such as adhesion, wetting and reactivity. These behaviors affect FPD device yield, performance, and lifespan. During FPD production, display glasses are exposed to chemical treatments including acids, bases, and detergents, which alter surface composition. Previous studies have noted that hydroxyls are the most important functional group on display glass. To understand the relationship between glass surface composition and surface-mediated processes, we have attempted to quantify surface hydroxyl concentration on display glasses using time-of-flight secondary ion mass spectrometry (ToF-SIMS). The SiOH+ / Si+ ratio measured from display glass surfaces changes in response to chemical treatments and sample heating, providing insight into glass hydroxylation state as a function of production environment.
