Why Organics? • Displays - Brighter (OLEDs) - Thinner (OLEDs) - Flexible (o-TFTs) Organic TFTs may be used to drive LCDs and potentially even OLEDs, allowing integration of entire displays on plastic OLEDs offer much better brightness, contrast, viewing angle, and potentially process simplicity that LCDs.

Why Organics • Low-Cost Electronics - No vacuum processing (PVD/CVD/Etch) - No lithography (printing) - Low-cost substrates (plastic, paper, even cloth…) - Additive process (lower abatement costs) - Direct integration on package (lower insertion costs) Electronic “Bar Code” Passive RF circuit that talk to the outside world… no need for scanners

Why Organics • At the nanoscale, organics may allow us to achieve more, in a manner complementary to silicon -Functionality – organic materials may do “more” than silicon -Density – Molecular-scale devices may be “smaller” than silicon FETs -Integration – Organic materials can be processed at very low temperatures using localized processing, allowing stacking and heterogeneous integration In the MARCO MSD center, we focus on the use of organic / molecular devices as evolutionary / complementary alternatives to silicon technology neutral positive charge negative charge Low voltage diode anode cathode tunnel gap

Where are we now? 1.E-06 1.E-05 1.E-04 1.E-03 1.E-02 1.E-01 1.E+00 1.E+01 1986 1988 1990 1992 1994 1996 1998 Mobility (cm2/V-s) Soluble (Spin-Cast) Evaporated These numbers are MUCH lower than Si, but are good enough for some applications in displays and RFID Evaporated films do not offer a compelling cost advantage over silicon The best results are all PMOS. No good NMOS candidate exists at this time
