Abstract

A method for forming an electronic device in a multilayer structure comprising the steps of: defining a topographic profile in a laterally extending first layer; depositing at least one non-planarizing layer on top of the first layer such that the topographic profile of the surface of the or each non-planarizing layer conforms to that of the laterally extending first layer; and depositing a pattern of at least one additional layer onto the top-most non-planarizing layer, such that the lateral location of the additional layer is defined by the shape of the topographic profile of the non-planarizing layer, and whereby the additional layer is laterally aligned with the topographic profile in the first layer.
