Abstract

In an organic electronic circuit, particularly a memory circuit with an organic ferroelectric or electret material the active material comprises fluorine atoms and consists of various organic materials. The active material is located between a first electrode and a second electrode. A cell with a capacitor-like structure is defined in the active material and can be accessed for an addressing operation via the first and the second electrode. At least one of these electrodes comprises a layer of chemically modified gold. In a passive matrix-addressable electronic device, particularly a ferroelectric or electret memory device, circuits of this kind with the active material as a ferroelectric or electret memory material form the elements of a matrix-addressable array and define the memory cells provided between first and second set of addressing electrodes. At least the electrodes of at least one of the sets then comprise at least a layer of gold. A method in the fabrication of the organic electronic circuit the method comprises steps for depositing a layer of gold as at least one layer of at least one electrode and treating an exposed surface on this layer chemically, whereafter the l…
