Abstract
A stack of layers can be formed adjacent to a substrate before any layer within the stack is patterned. In an embodiment, combinations of substrates and stacks can be made and stored for an extended period, such as more than a week or a month, or shipped to a remote location before further manufacturing occurs. By delaying irreversible patterning until the closer to the date final product will be shipped to a customer, the likelihood of having too much inventory of a particular size or having to scrap windows for a custom order that was cancelled after manufacturing started can be substantially reduced. Further, particles between layers of the stack can be avoided. The process flows described are flexible, and many of the patterning operations in forming holes, openings, or the high resistance region can be performed in many different orders.
