Abstract
A high temperature substrate having improved properties. The substrate is a polymer substrate having a glass transition temperature greater than about 120° C., and at least one first barrier stack adjacent to the polymer substrate. The barrier stack includes at least one first barrier layer and at least one first polymer layer. A method for making the high temperature substrate with improved properties is also disclosed.
