METHOD TO FORM A PATTERN OF FUNCTIONAL MATERIAL ON A SUBSTRATE USING A MASK MATERIAL

摘要

The invention provides a method to form a pattern (55) of functional material (46) on a substrate (34) for use in electronic devices and components. The method uses a stamp having a relief structure to transfer a mask material (32) to a substrate (34) and form a pattern of open area (42) on the substrate (34). The functional material (46) is applied to the substrate (34) in at least the open area (42). Contact of an adhesive material (52) to an exterior surface (56) opposite the substrate (34) and separation of the adhesive from the substrate forms the pattern (55) of functional material (46) on the substrate (34). The method is- suitable for the fabrication of microcircuitry for electronic devices and components.,
