Patent ID: 8372731

Claim:
A method for fabricating an electronic device, the method comprising: embossing a surface of a work-piece using an embossing tool so as to form a microstructure including a stepped indentation in the work-piece surface, the indentation having first and second portions indented into the work-piece surface, the first portion being more indented than the second portion and overlapping the second portion when viewed from a direction normal to the work-piece surface so as to form a step between the first portion and the second portion; and depositing fluid containing a functional material onto the microstructure, the step of depositing fluid including: depositing a first layer of material in the first portion; depositing a second layer of material on the first layer of material and in the second portion; and depositing a third layer of material on the second layer of material and in the second portion, whereby a side edge of the second portion, a side edge of the third layer of material and a side edge of the second layer of material coincide when viewed from a direction normal to the work-piece surface, wherein the side edges define the extremities in the plane of the work-piece surface of the second portion, the third layer of material and the second layer of material respectively, and the side edges extend in a direction substantially normal to the work-piece surface.
