Abstract
A method for making a liquid barrier includes forming a liquid barrier layer on a substrate, forming a mask layer on the liquid barrier layer such that part of the liquid barrier remains exposed, forming a contact layer on the exposed liquid barrier layer, and removing the mask layer to expose the part of the liquid barrier layer which was covered by the mask layer. A liquid wetting boundary is formed when the wettability on the liquid barrier surface area is less than the wettability of the contact surface area.
