Abstract
A device and method for improving adhesion for thin film layers includes applying a diblock copolymer on a surface where adhesion to subsequent layers is needed and curing the diblock copolymer. Pores are formed in the diblock copolymer by treating the diblock copolymer with a solvent. The surface is etched through the pores of the diblock copolymer to form adhesion promoting features. The diblock copolymer is removed, and a layer is deposited on the surface wherein the adhesion promoting features are employed to promote adhesion between the layer and the surface.
