The alkaline earth boro-aluminosilicate glass 1737F is highly resistant to temperature and thermal shock. It is a near-zero alkali glass developed by CORNING that withstands the rigorous cycles of poly-silicon transistor processes. A low alkali content and its high strain point of 666 °C allow unique manufacturing processes required for various electronic components that are not possible with most other glass materials. A coefficient of thermal expansion close to the one of silicon opens up the option for chip-on-glass (COG) applications. Furthermore, 1737F features an exceptionally low microroughness and an excellent optical quality. In general, the natural surfaces of 1737F glass already have a lower micro-roughness than most mechanically polished glass at the same thickness. Hence, this glass is an exquisite substrate choice for optical- filter or mirror coatings. Corning 1737 glass materials are more durable than their predecessor 7059 and have an even lower alkali content and less shrinkage. Unannealed 1737F LCD glass can replace annealed 7059 glass in most applications, resulting in considerable cost savings. A newer, almost alkali-free glass representing an alternative to 1737F is CORNING's EAGLE 2000.
