Patent ID: 7521351

Claim:
A method for forming a semiconductor product, the method comprising: providing a substrate comprising active areas, depositing a first dielectric layer, etching contact holes in the first dielectric layer for contacting the active areas, depositing a first conductive layer thereby filling the contact holes in the first dielectric layer and forming a plurality of contact hole fillings in the first dielectric layer, depositing a second dielectric layer having an upper surface, etching contact holes in the second dielectric layer, each contact hole in the second dielectric layer exposing a portion of a surface of a respective contact hole filling of the first dielectric layer and having a width in a first lateral direction, depositing a second conductive layer, filling the contact holes of the second dielectric layer and covering the second dielectric layer, and patterning the second conductive layer thereby forming conductive lines, each conductive line passing over a plurality of contact holes of the second dielectric layer and having a width in the first lateral direction being smaller than the width of the contact holes of the second dielectric layer, wherein a top surface of a conductive material of the second conductive layer that is provided in the contact holes of the second dielectric layer and that is arranged, in the first lateral direction, outside the width of the respective conductive line passing over the respective contact hole, is at least recessed below the upper surface of the second dielectric layer.
