Abstract: Methods for forming an integrated semiconductor circuit arrangement are disclosed. In one embodiment, a semiconductor circuit with a first semiconductor circuit region and with a second semiconductor circuit region is formed in each case in a semiconductor material region. A first metallization layer is applied to the structure thus obtained. A protective material region is then formed. A second metallization layer is subsequently applied, which is then also patterned. Afterward, the first metallization layer together with the protective material region is then patterned.

Abstract: In a semiconductor device, a contact stud (100) contacts a semiconductor substrate (10); the stud is embedded in an insulating structure with a first insulating layer (20) and a second insulating layer (20′). During manufacturing, (a) the first layer (20) is provided above the substrate (10); (b) a hole in the first layer (20) exposes a portion of the upper surface of the substrate to receive the stud; (c) a contact material (30, 40) is provided at the top of the resulting structure; (d) a first chemical-mechanical polishing (CMP) removes the contact material from the surface of the first layer (20) outside the hole; (e) residuals (50) of the contact material are cleaned away from the upper surface; (f) the second insulating layer (20′) is provided at the surface of the resulting structure; (g) and further polishing is applied.
