A method for fabricating an interconnect system is provided. A low dielectric constant layer (LDCL) is formed onto a substrate. A hard mask is formed onto the LDCL. A patterning material is formed onto the hard mask. The patterning material is via patterned. A via pattern of the patterning material is transferred to the hard mask. The patterning material is stripped at a substantially low temperature. Vias are formed through the LDC using a via pattern formed in the hard mask.
