摘要: A technique for employing polyimide as an inter-metal dielectric layer, while avoiding the difficulties usually associated with this material. An upper layer of silicon dioxide is employed as a hard mask over the polyimide, and is highly doped with phosphorous to prevent thermal cracking. Via holes are formed in a multi-stage etching process that includes a first dry-etching step that effects isotropic etching to form holes with desirably sloped sidewalls, and a second dry-etching step that effects anisotropic etching to extend the via holes through to a lower metal surface without significantly enlarging the holes in width. Finally, a dry-etching step is used to remove any residue of polyimide and to strip the silicon dioxide layer from over the polyimide. The bottom of the hole is then sputter-etched prior to metallization. In one preferred form of the method, a lower layer of silicon dioxide is formed between the lower metal layer and the polyimide layer, to facilitate removal of polyimide residue and to act as a barrier between the lower metal and the polyimide.
