摘要： A method of manufacturing an electronic device comprises: providing a base comprising circuit elements; forming a double bank well-defining structure over the base, comprising a first layer of insulating material and a second layer of insulating material thereover; and depositing a solution of organic material in the well defined by the double bank structure. The double bank well-defining structure is formed by removing material from the first and second layers in a single processing step to form the well. The first layer is made of a material which is removed at a faster rate than material of the second layer to form an overhanging step structure in which the second layer protrudes out over an edge of the first layer.
