Definitions
- the invention relates to the production of organic field-effect transistors (OFETs), solar cells or light-emitting diodes (OLEDs) and circuits based thereon on the surface of solvent- and / or temperature-sensitive plastics, e.g. thermoplastic injection molded bodies.
- OFETs organic field-effect transistors
- OLEDs light-emitting diodes
- the invention further relates to electronic components which are produced by this method.
- OFETs organic field-effect transistors
- substrates such as silicon, glass, polyester film (PET, PEN) or polyimide film using simple processes ⁇ CJ Drury, CM. J. Mutsaers' CM. Hart, M. Matters and DM de Leeuw: Appl. Phys. Lett. 73 (1998), 108; F. Eder, H. Klauk, M. Halik, U. Zschieschang, G. Schmid and C. Dehm, Appl. Phys. Lett. 84 (2004), 2673; J. Ficker, A. Ullmann, W. Fix, H.
- the maximum continuous service temperature of the carrier material is also important for process control. These requirements are largely met, for example, by polyethylene terephthalate (PET) and polyimide.
- a gate insulator for an organic HL device in particular for a field effect transistor is described which consists of a crosslinked at temperatures between 150 0 C and 200 0 C polysiloxane compound.
- polysilane used for electrical insulation to protect loxan für ABS, polycarbonate or Polysty- rolsubstraten not possible against harmful effects of solvents during the manufacturing process.
- ÜS2003 / 0224621 a method for producing organic semiconductor systems on various documents such as textiles is given. This method also includes the bring a protective layer on the substrate surface below the semiconductor. However, it obviously does not serve to protect the substrate from chemical effects by solvents. Also, no information is given about the chemical composition of the protective layer.
- injection molding materials such as ABS polymer, polycarbonate and polystyrene into consideration.
- these injection molding materials unlike silicon, glass, polyimide, and other substrate materials, many of these injection molding materials, which often serve as electronic packaging materials, compact disks (CDs), and DVDs, are sensitive to organic solvents. In addition, they are thermally mostly low loadable.
- the roughness of the surface of the injection molding tool used also determines the surface roughness of the substrate, so that injection molding materials are only of limited use as base materials for organic electronics.
- the object of the invention is therefore to provide a simple and inexpensive process for producing organic field effect transistors (OFETs), solar cells or light-emitting
- OLEDs Specify diodes
- an organic layer is applied, for example, partially or on the entire substrate surface of an injection-molded body, which is insoluble in relation to the solvents used below and whose production does not require too high temperatures.
- Layer thicknesses between 1 ⁇ m and 5 ⁇ m are generally sufficient to protect the surface of this plastic body from solvent attack.
- the mostly rough surface is smoothed out.
- Crosslinkable polymers such as acrylates, polyester or epoxy resins prove to be particularly suitable.
- the crosslinking should be carried out at low temperatures or photochemically.
- the application of the protective layer can also in large-scale coating method, for. B. by printing, knife coating or local dripping (microdosing) happen. Then the structure of the organic components and their circuits is then made.
- Organic or polymeric field effect transistors in the sense of this invention comprise at least the following function-determining layers on a substrate: an organic semiconductor layer between and under at least one source and at least one drain electrode which are made of a conductive organic or inorganic material , an organic insulation layer over or below the semiconductive layer and an organic conductor layer.
- the corresponding integrated organic or polymer electronic circuits consist of at least two organic or polymeric field-effect transistors.
- Figures 1 and 2 show schematically and in sectional view field effect transistors according to the two embodiments, wherein in Figure 2, a variant was selected for the layer structure in which the layers are arranged inversely to the structure shown in Figure 1.
- a gate electrode 5 is generated directly on the surface of a plastic body 1 of a conductive polymer dispersion, which does not attack the plastic surface. This may be, for example, an aqueous or alcoholic dispersion of a carbon black composite.
- an (insulating) protective layer 6 is applied, which protects the plastic or injection-molded body 1 from solvents and at the same time serves as an insulator between the gate electrode 5 and the source or drain electrode 2, 4.
- an organic semiconductor layer 3 and the source or drain electrode 2, 4 are then applied.
- the order of the polymer layers can be done by printing or dripping (microdosing). The structuring of the electrodes can, if this has not already been done during printing, e.g. achieve by laser processing.
- FIG. 1 describes a realization of the invention according to FIG. 1.
- the networking takes place with a high-performance ÜV lamp with an exposure time of up to 3 seconds.
- the layer thickness is about 5 microns.
- a layer of a conductive carbon black polymer composite is also applied by doctoring.
- the source-drain electrodes 2,4 are produced by selective removal with an excimer laser.
- the polymer semiconductor 3 poly-3-dodecylthiophene
- the polymer semiconductor 3 from a 0.25% solution of chloroform or toluene is applied by spin coating (4000 U / min).
- As insulator layer 6 polyvinylphenol is spin-coated from a 20% solution at 2000 revolutions / minute.
- the gate electrodes 5 are made by local application of a colloidal graphite.
- Figure 3
- Example 2 This example involves implementation of the invention as shown in Figure 2.
- a layer of the conductive polymer Polyethylendioxythiophen (Baytron) is geräkelt. This layer is patterned by selective removal with an excimer laser, so that the gate electrodes 5 are obtained.
- the (insulating) protective layer 6 a layer of an alcoholic polyvinylphenol solution containing a crosslinking agent is applied by spinning at 2000 rpm.
- the Polyvinylphenol für anschlieOend is annealed for 3 hours at 70 0 C.
- a thin gold layer (about 20 nm) is sputtered, from which in turn the source-drain electrodes 2, 4 are generated with an excimer laser.
- the semiconductor layer 3 is applied by spin-coating a 0.25% poly-3-hexylthiophene solution in toluene.
- the output characteristics of a field effect transistor produced in this way are shown in FIG. 4.
