An embodiment of the invention provides an integrated circuit having an organic field effect transistor (OFET) with a dielectric layer. The dielectric layer is prepared from a polymer formulation comprising: about 100 parts of at least one crosslinkable base polymer, from about 10 to about 20 parts of at least one di- or tribenzyl alcohol compound as an electrophilic crosslinking component, from about 0.2 to about 10 parts of at least one photo acid generator, and at least one solvent. Another embodiment provides a semiconductor fabrication method. The method comprises applying the polymer formulation to a surface of a substrate, drying the polymer formulation, crosslinking the polymer formulation after drying, and baking the polymer formulation after crosslinking.

The gate dielectric layer of a thin film field effect transistor is formed as a multilayer layer system having at least one self assembling molecular monolayer (SAM) and a dielectric polymer layer made of an insulating polymer. With comparatively small layer thicknesses of 10 to 50 nanometers, the multilayer gate dielectric layer ensures low leakage currents and enables failsafe operation of the thin film field effect transistor at low supply voltages of less than 5 volts. The gate dielectric layer is robust toward voltages of up to approximately 20 volts and permits the use of a multiplicity of different materials for realizing an underlying electrode.

A semiconductor component has at least one organic semiconductor layer. The component also includes at least one protective layer for at least partially covering the at least one organic semiconductor layer to protect against environmental influences. The at least one protective layer contains a proportion of an alkane with CHand n greater than or equal to 15 or consists entirely of an alkane of this type, or of a mixture of alkanes of this type. In one example, the protective layer is a paraffin wax. This creates a high resistance to moisture.

A laminate is formed from a carrier layer and an electrically conductive layer. In one section, the conductive layer is formed into an antenna structure. The laminate is formed by placing a mask onto a packaging film and vapor-depositing aluminum onto the packaging film and the mask. After removal of the mask, only a desired antenna structure remains on a section of the packaging film. Then a microchip, is adhesively bonded to the packaging film and conductively connected to an end of the antenna structure, so that data can be written in or read out without contact in a wireless transponder system.

In the case of the materials according to the invention, the charge carrier mobility in the correspondingly prepared films is achieved if the molecules are composed in such a way that side chains&#x2014;consisting of conjugated aromatic or heteroaromatic systems&#x2014;are attached in direct conjugation to a central aromatic or heteroaromatic ring so that the total molecule acquires an octupolar structure. This octupolar structure permits an effective &#x3c0;-&#x3c0; interaction of the molecules with one another in a manner such that stacking of a plurality of molecules along an imaginary axis (central ring) can take place and various stacks from among these stacks can interact with one another by intermeshing of the side chains. The electronic properties of the materials are determined both by the arrangement of the molecules in a layer and by the molecular design. The type of side chains and of the central ring which is electronically coupled to the side chains and ideally reinforces the effects in comparison with side chains considered in isolation is important for this purpose.

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.
