Abstract: A maskless process for forming a protected metal feature in a planar insulating layer of a substrate is disclosed. A first barrier material is disposed in a recess in an insulating layer, a conductive metal is disposed on the first barrier material such that the entire metal feature is positioned within the recess below the top of the recess, a second barrier material is disposed on the metal feature such that the second barrier material occupies the entire portion of the recess above the-metal feature and extends above the top surface of the insulating layer, and the second barrier material is then polished until the top of the second barrier material is in and aligned with the top of the insulating layer. As a result, the metal feature is surrounded and protected by the first and second barrier materials, and the substrate is planarized.

Abstract: A method of forming an etch mask and patterning a substrate. The method includes directing a particle beam at a substrate without using a mask to deposit an etch mask on the substrate which selectively exposes predetermined portions of the substrate, the etch mask consisting of particles mechanically placed on the substrate by the particle beam, and then etching the exposed portions of the substrate through the etch mask to form channels therein. The process is well suited to fabricating high density copper/polyimide multi-chip modules.
