Abstract:
A method of forming a patterned layer on a substantially planar surface, comprising(a) microdispensing, at a predetermined location, an amount of a photoformable matrix onto said planar surface sufficient to cover a predetermined area having a defined perimeter and to extend beyond said area and perimeter, forming a microdispensed matrix, wherein the area covered by the microdispensed matrix is less than the entire area of the planar surface;(b) drying said microdispensed matrix;(c) aligning said microdispensed matrix with a mask of the predetermined area and defined perimeter at the predetermined location to form an aligned matrix;(d) exposing said aligned matrix to radiation to form an exposed matrix; and(e) developing said exposed matrix to remove excess microdispensed photoformable matrix, such that a patterned layer is formed at the predetermined location, said patterned layer having the predetermined area and defined perimeter.
