Since its introduction a couple of years ago, Corning's 1737 AMLCD substrate glass has received good market support. Some of this was anticipated as this glass offers several obvious improvements over existing substrates. However, some came unexpectedly, as AMLCD makers discovered new attributes offered by this glass. Primarlily, a higher glass strain point, translating into a substrate with greater thermal stability; a lower density, resulting in lower weight and less gravitational sag; improved chemical durability, allowing more aggressive etching conditions; and a coefficient of thermal expansion more closely matched to silicon, opening up the possibility of chip-on-glass (COG). This paper reviews the development of Code 1737 glass and outlines its benefits.
