The conductivity of an initially insulating emeraldine base film can be controlled by adjusting its time of exposure to the vapor of a dopant solution. Before saturation doping is achieved, however, large nonuniformities in resistivity are measured i

In future generation microelectronic devices, it is anticipated that back end of the line processing may incorporate interconnects composed of Cu metal, and inter-level dielectrics composed of organic polymers. In this study, we examined a number of

A major issue with copper metallization is the diffusion and/or dissolution of copper into polymers used as insulating dielectric layers in microelectronic devices. Polymers are typically deposited by spin-coating. But when substrate-polymer interact

Control of the internal morphology of wet-spun fibers from a fluorinated polyimide has been achieved by varying the rate of polymer coagulation through adjustments in nonsolvent/solvent miscibility and precipitation strength of the coagulation bath.
