摘要:
In a method of fabricating a semiconductor structure, a carbon containing mask is fabricated over a dielectric layer. The mask exposes the surface of the dielectric layer at least partly in a region between two adjacent conducting lines. A contact hole is etched into the dielectric layer in the region between the two adjacent conducting lines.
