Brief description of the formation of a component of the memorisation of the type memory has bubbles and component produced by this

摘要

P the invention relates to the formation of components by a memory has bubbles. / p & & p & the method consists in deposit a first dielectric layer 12 on a substrate of garnet 10. It forms a second dielectric layer 14 on the first. It is formed on the second layer is a diagram of a protective lining is then etched in the rectilinear walls by a means which do not the first layer decape. It is deposit a conductive layer 20 in the notches formed during the etching and on the surface of the diagram of a protective lining. It applies a material of the protective coating material on the part that is relatively small, for be covered by a conductor, in accordance with the conductive layer is preserve. It is chemically decape this conductive layer in the regions not covered by the material of the protective lining coarse. Finally, it removes the protective coating material of the coarse remaining in the same time as the coucheconductrice in order to leave a flat surface constituted by a conductor at the level of a surface in the same plane as the surface of the second layer. / p
