Temperature-resolved ToF-SIMS of Display Glass Surfaces
Multicomponent glasses are preferred substrates for manufacturing flat panel displays, and their surface properties can influence the display manufacturing process. Among the relevant surface attributes, the hydroxylation state of the surface is thought to be important in mediating properties such as adhesion and charging. Few studies address the surface hydroxyl concentration of planar substrates, and fewer still attempt to quantify them on multi-component glass surfaces. This is a challenging analytical task because planar substrates have low surface area and relatively low hydroxyl density, glass surface composition typically varies from its bulk composition, and multicomponent glasses can have hydroxyl groups of different identity, and analyses are complicated by the presence of mobile modifier ions. Our project is to understand the how glass surface composition affects surface-mediated behaviors including; wetting, thin film adhesion, surface contamination and surface reactivity. We will achieve this via TOF-SIMS analysis with several different sample types to understand the surface composition of the glass substrates.
