  • Reduction of the contact resistance in organic field-effect transistors with palladium contacts by using phosphines and metal-containing phosphines
    Patent number: 7208782
    Abstract: A semiconductor device includes a semiconductor path, the semiconductor path including an organic semiconductor material, a first contact to inject charge carriers into the semiconductor path, a second contact to extract charge carriers from the semiconductor path, and a layer including phosphine arranged between the first contact and the semiconductor path and/or between the second contact and the semiconductor path. The phosphine in the layer acts as a charge transfer molecule which makes it easier to transfer charge carriers between contact and organic semiconductor material. As a result, the contact resistance between contact and organic semiconductor material can be reduced considerably.
    Type: Grant
    Filed: January 31, 2005
    Date of Patent: April 24, 2007
    Assignee: Infineon Technologies, AG
    Inventors: Hagen Klauk, Günter Schmid, Ute Zschieschang, Marcus Halik, Efstratios Terzoglu
  • Reducing the contact resistance in organic field-effect transistors with palladium contacts by using nitriles and isonitriles
    Patent number: 7151275
    Abstract: A semiconductor device includes a semiconductor section formed from an organic semiconductor material, a first contact for injecting charge carriers into the semiconductor section and a second contact for extracting charge carriers from the semiconductor section, wherein a layer of a nitrile or of an isonitrile is arranged between the first contact and the semiconductor section and/or between the second contact and the semiconductor section. The nitrile or isonitrile acts as a charge transfer molecule facilitating the transfer of charge carriers between contact and organic semiconductor material. This allows the contact resistance between contact and organic semiconductor material to be significantly reduced.
