摘要:
A semiconductor device with a bonding section comprising a semiconductor substrate, a silicon layer formed on the semiconductor substrate with a first insulating layer interposed therebetween, and a bonding pad formed on the silicon layer with a second insulating layer interposed therebetween. The silicon layer has substantially the same size as the bonding pad. When a lead line is bonded to the bonding pad, the silicon layer lessens the stress caused by the bonding.

A metallization structure having a substantially flat surface can be formed on a semiconductor substrate by forming first and second insulating layers on the substrate. The second insulating layer is selectively removed to form grooves therein. Then, a metallic material layer is conformably formed. The metallic layer has grooves corresponding to the grooves of the second insulating layer. A flowable polymer is applied to the surface of the resultant structure to form a layer having a flat surface. The polymer layer and the metallic layer are sequentially ion-etched to expose the second insulating layer. Thus, the metallization structure constituted by the remaining metallic layer and the second insulating layer is formed to have a flat surface.

摘要:
There are provided a semiconductor device having alternately layered insulating and conductive layers on the major surface of a semiconductor body and the process for manufacturing the semiconductor device. In the manufacturing process, the conductive layers other than the conductive layer finally formed are each formed to be a laminate including at least two metal layers of which the etching rates are different. The photo-engraving process follows this step. In the lamina, the metal layer closer to the semiconductor body has a lower etching rate than that of the metal layer formed thereover. In the semiconductor device, the conductive layer other than that disposed furthest away from the semiconductor body has its side wall diverged to widen toward the semiconductor body.
