    Abstract: An interconnect structure with a via (66) embedded in a first low dielectric constant material (44) and a trench (66) embedded in a second low dielectric constant material (48), which is a different material than the first low dielectric constant material (44), is formed. In one embodiment, the second low dielectric constant material (48) is used as a mask for etching the first low dielectric constant material (44). Also, in one embodiment, the first low dielectric constant material (44) may be used as an etch stop layer for etching the second low dielectric constant material. The second low dielectric constant material (48) may include silicon and oxygen and the first low dielectric constant material (44) may be organic.
