During the last 50 years polymeric materials have played an important role in semiconductor fabrication, interconnect, packaging and displays. They have usually played a passive role and have not been involved in the active generation, amplification, and switching of current or voltage. This is now changing. Research efforts on polyanalines, conjugated thiophene oligomers and polymers and pentacene and thiophene oligimers have led to improvements of mobility by 5 orders of magnitude over the last 15 years. Polymeric semiconductors offer a means to create unique, low cost electronic devices since they can be readily fabricated into thin, mechanically robust films onto a variety of substrates by low cost processing techniques. Recently new generations of polymeric semiconductors have been developed. All plastic chips based entirely on organic materials have been demonstrated. Materials based on fluorene-arylene copolymers are under development for this purpose. This paper describes recent work with this family of materials, compares results obtained by different research groups, and discusses issues related to the interplay of device construction and material characterization with a focus toward printed electronics.
