Asahi Glass Company (AGC) recently announced the company has developed a carrier glass technology to laminate its 0.1 mm-thick ultra-thin glass on carrier glass for easier handling and transportation during product manufacturing processes.
Customers now can utilise ultra-thin glass without altering their existing production facilities, a major stride toward the commercialisation of ultra-thin glass for next-generation displays and various other applications.
Ultra-thin glass, which AGC developed last year, offers excellent transparency, heat resistance and electrical insulation, as well as extra thinness and flexibility, making it ideal for next-generation displays, touch-screens and lighting equipment.
The roll-to-roll production method, which is currently under development, enables rolls of ultra-thin glass to be used conveniently in continuous strips during production. However, the method has required substantial alterations in production facilities to ensure proper handling of the ultra-thin glass.
To overcome this need and thereby accelerate commercialization, AGC has now developed the technology to laminate ultra-thin glass onto approx. 0.5 mm carrier glass. The laminated glass substrate can be handled much the same as ordinary glass sheet (sheet-to-sheet method), enabling circuit formation and other processing of ultra-thin glass without having to alter existing production facilities.
Ultra-thin glass and carrier glass are laminated via a special bonding layer that makes the laminated substrate high resistant to heating and chemical processing during production. Furthermore, the carrier glass prevents the ultra-thin glass from coming into direct contact with processing equipment to prevent defects such as scratches, and can be easily delaminated after processing.
