[Uses] Semi-conductor material. Dielectric component in thin films, high density interconnect systems and multichip modules.
[General Description] Poly(pyromellitic dianhydride-co-4,4′-oxydianiline), amic acid solution (PAA) converts to polyimide at 300^oC. The FTIR spectra indicates a carbonyl stretch of carboxylic acids in PAA at 1650 cm^-1. Following the imidization process, the peak at 1720cm^-1grows, indicating the formation of imide group.
