Abstract:
The invention relates to a method for metallizing dielectrics during which a photosensitive dielectric is applied to a substrate. The dielectric is then exposed to light though a mask, is seeded with a metal and subjected to a temperature treatment and, afterwards, the dielectric is chemically metallized. Alternatively, the dielectric can be firstly seeded with a metal after being applied to the substrate, and then exposed to light through a mask. Afterwards, excess seeding material is removed and the dielectric is chemically metallized.

The invention relates to a force sensor based on an organic field effect transistor (10) that is applied to a substrate (1; 11). According to the invention, a mechanical force that acts on the transistor causes a corresponding modification of the source-drain voltage or the source-drain current (ID), whereby said modification can be respectively detected as a measured variable (Vmess, Imess) for the exerted force.

Abstract:
The invention relates to a resistive storage element containing a dielectric as the storage medium, in which isolated nanoparticles are arranged. The dielectric is preferably configured from an organic polymer. The storage element exhibits a resistive hysteresis effect. Below a voltage Vhold, the storage element is switched to a slightly conductive state, whereas above a voltage Vkrit, the storage element changes over into a conductive state. The conductive state of the storage element can be read out by applying a voltage that lies between Vhold and Vkrit.<>
Abstract:
The invention relates to a semiconductor device comprising a semiconductor section consisting of 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. A phosphine layer is located between the first contact and the semiconductor section and/or between the second contact and the semiconductor section. The phosphine acts as a charge transfer molecule, which facilitates the transfer of charge carriers between the contact and the organic semiconductor material. This enables the contact resistance between the contact and the organic material to be significantly reduced.
