Abstract:
An integrated device includes a semiconductor body and a dielectric layer bounded by a surface. A conductive region of a first metal material forms a via region extending into a hole passing through the dielectric layer, and an overlaid redistribution region which extends over the surface. At least one barrier region of a second metal material extends into the hole and surrounds the via region, and the barrier region furthermore extending over the surface. A first coating layer of a third metal material covers the top and the sides of an upper portion of the redistribution region at a distance from the surface. A second coating layer of a fourth metal material extends at a distance from the surface and covers the first coating layer, and covers laterally a lower portion of the redistribution region which is disposed on top of portions of the barrier region extending over the surface.

Claim (Index 12):
A fabrication process for an integrated electronic device, comprising:\n forming a hole through a frontal dielectric layer of a die including a semiconductor body and a passivation structure including the frontal dielectric layer, the frontal dielectric layer having a frontal surface; forming a via region extending into the hole; forming a redistribution region over the via region and extending over the frontal surface of the frontal dielectric layer, the redistribution region including an upper portion including a top and sides, and a lower portion of the redistribution region proximate the frontal surface of the frontal dielectric layer; forming a first barrier region extending into the hole and surrounding the via region, the first barrier region including portions extending over the frontal surface; forming a first coating layer on the top and sides of the upper portion of the redistribution region, the first coating layer having a portion proximate the frontal surface but at a distance and physically separated from the frontal surface; and forming a second coating layer over the first coating layer and covering laterally the lower portion of the redistribution region and portions of the first barrier region extending over the frontal surface.
