    摘要: A method for forming a plurality of electrically conductive wires on a substrate. The method includes forming a relatively non-planar metal layer over a surface of the substrate. A self-planarizing material is deposited over the metal layer. The self-planarizing material forms a planarization layer over the surface of the metal layer. The planarization layer has a surface relatively planar compared to the relatively non-planar metal layer. A photoresist layer is deposited over the surface of the planarization layer. The photoresist layer is patterned with a plurality of grooves to form a mask with such grooves exposing underling portions of the planarization layer. The photoresist mask is used as a mask to etch grooves in the exposed portions of the planarization layer and thereby form a second mask. The second mask exposes underling portions of the relatively non-planar metal layer. The second mask is used to etch grooves in the relatively non-planar conductive metal layer and thereby form the plurality of electrically conductive wires in the metal layer. The wires are separated from each other by the grooves formed in the relatively non-planar metal layer. The planarization layer is formed by a spinning-on an organic polymer, for example an organic polymer having silicon, or a flowable oxide, or a hydrogensilsequioxane, or divinyl-siloxane-benzocyclobutene. The metal layer is etched using reactive ion etching. The planarization layer is removed using a wet chemical etch.

    摘要: A fine pattern is formed by the following steps. A prescribed mask pattern of an electrically insulative material (3, 5, 8) is formed on an electroconductive surface of a base plate (2) of a printing plate (1), so that the part, other than the mask pattern, of the printing plate becomes an electroconductive printing pattern part . Then, the printing plate (1) is electrolized and the electrodeposition substance (14) is deposited on the electroconductive printing pattern part of the printing plate (1). Then, the deposited substance (14) is transferred onto the surface of a printing object (20) such as a plate of glass or plastic, for forming a pattern thereon. Thereafter, the surface of the printing object (20) is etched with the electrodeposited substance (14) thus transferred as an erosion resistant material.

    摘要: It is described a process to obtain thin film lines by photolithography of thick resist (3) and subsequent selective galvanic growth of gold which enables to obtain very thin lines (8) (2-10 micron) with high definition, that is with nearly vertical walls (9) and with a tolerance in the width of about 1 micron. Such results have been achieved by using polyimide as thick resist (3), by particular cure cycles of the same polyimide and by a particular dry etching of the polyimide layer (3) to obtain seats (6) in which afterwards the lines (8) become grown.
