Abstract:
A photoresist conversion that changes a patterned photoresist into a permanent patterned interconnect dielectric is described. The photoresist conversion process includes adding a dielectric enabling element into a patterned photoresist. The dielectric enabling element-containing photoresist is converted into a permanent patterned dielectric material by performing a curing step. In one embodiment, a method is described that includes providing at least one photoresist to an upper surface of a substrate. At least one interconnect pattern is formed into the at least one photoresist. A dielectric enabling element is added to the patterned photoresist and thereafter the patterned photoresist including the dielectric enabling element is cured into a cured permanent patterned dielectric material. The cured permanent patterned dielectric material includes the dielectric enabling therein.
