33rd Edition DIC : 2536 Glossary Strain point A temperature at which internal stress in glass is removed in several hours. Below this temperature thermal stress is not substantially generated, so this would be the standard temperature for heat resistance. Annealing point A temperature at which internal stress in glass is removed in several minutes. This would be the standard temperature for annealing. Transformation point A temperature at which the inclination of the thermal expansion curve suddenly changes. This corresponds to the transformation of glass from solid state to liquid state. Deformation point A temperature at which thermal expansion is not any more detected in the measurement because of softening of glass. It appears as a peak of the expansion curve. Softening point A temperature at which glass deforms noticeably by its own weight. There are two measurement methods, fiber elongation method and differential thermal analysis (DTA). The measurements from both methods do not coincide. Softening point for powder glass is usually measured with DTA. Working point A temperature at which viscosity of the glass is 104dPa・s. It is a standard temperature for glass forming such as tubing and pressing. Glass flowing point A temperature at which viscosity of the glass is 105dPa・s. Glass becomes soft enough to flow and spread. Sealing temperature/Firing temperature Processing temperature suitable for sealing or firing. Contents / Electronic Glass Materials 1.

No.1910-01E OA-10G/OA-11 Glass Substrate OA-10G and OA-11 are used as substrates for liquid crystal displays and OLED displays, as well as substrates for the formation of various thin films. OA-11 has particularly low deformation and deflection of gravity properties. The substrate is both very thin and highly useful. The high dimensional stability of this glass substrate allows it to withstand high temperature processes which makes it suitable for use in the LTPS and IGZO high-quality-next-generation displays. Features 1. Smooth surface Glass substrates formed using overflow technology exhibits flat precision surfaces. 2. Alkali-free With a maximum alkali oxide content of 0.1% each, these products do not degrade the thin-film characteristics of amorphous or polycrystalline silicon. 3. Thermal dimensional stability A high strain point and a low thermal expansion coefficient give OA-10G and OA-11 high thermal dimensional stability during TFT forming process and other heat treatment processes. 4. Chemically stable surface Inert to treating agents used in the semiconductor process and the TFT forming process, so surfaces retain pristine quality. 5. Environmentally friendly glass Environmentally friendly glass that does not contain environmentally hazardous substances, such as As and Sb.
