Patent ID: 8435605

Claim:
A method, comprising: applying an inorganic barrier layer to at least a portion of a flexible substrate, the barrier layer comprising at least one of a tin fluorophosphate material, a chalcogenide material, a phosphate material, a borate material, a bismuth zinc borate material, a glass, a borosilicate glass, a tellurite material, and a material including a composition of about 72 parts SiO 2 , about 1 part Al 2 O 3 , about 25 parts B 2 O 3 , about 0.5 parts Li 2 O, about 0.5 parts Na 2 O, and about 1 part K 2 O, wherein: (i) a modulus of the barrier layer is about 30 GPa to about 120 GPa; and (ii) a thickness of the barrier layer is less than about 10 μm; and sintering the inorganic barrier layer while maintaining the flexible substrate below a critical temperature thereof.
