Abstract:
1. A method of producing a planar structure, comprising: a. producing on a first main surface of a substrate a plurality of structures, the structures being of substantially equal height, there being a space in between the plurality of structures; b. providing a fill layer of photosensitive material substantially filling the space between the structures; c. illuminating a portion of the fill layer with electromagnetic radiation so that the filler layer has one exposed portion and one unexposed portion, the exposed portion and unexposed portion being separated by a level interface substantially parallel with the first main surface of the substrate at a predetermined height level above the substrate; d. removing one of the unexposed portion and the exposed portion which is above the level interface so that, the rest of the fill layer and the plurality of structures form a planarized surface.
