Definitions
- the invention relates to a functional layer of an organic field effect transistor (OFET), an electrode and / or a conductor track and a regulation for printing the same.
- OFET organic field effect transistor
- Methods for printing organic functional layers are known, for example, from DE 100 33 112.2, in which soluble organic materials, in particular also soluble polymers, are printed as OFETs or as integrated circuits.
- Roll-to-roll processes which can be combined with embossing technology, are used in particular as printing techniques.
- the known printing techniques do not always lead to the specified patterns, designs or layouts because, for various reasons, the transmission does not always correspond 100% to the specified layout for a variety of reasons, but rather can only be passed on with a certain degree of blurring.
- the object of the present invention is therefore to create patterns or design rules for printing organic circuits which take into account the errors which are unavoidable due to printing in realitas and include them.
- the invention therefore relates to a functional layer, a conductor track, an electrode and / or a plated-through hole of an OFET, which can be produced using printing technology and whose corners are rounded and / or whose wide structures have been placed at a sufficiently large distance from one another and / or their conductor tracks are cross-connected so that a defect in the conductor track is compensated for by the cross-connection.
- a support interconnect in the event of a risk of interruption is referred to as a cross connection, which may prove necessary as follows:
- the conductor tracks usually have a width of up to 300 ⁇ m, but mostly less.
- the width of the conductor track is increased. In some places within a circuit, however, this is not possible due to lack of space or is not desirable for performance reasons. It is therefore important that a cross-connection is created that leaves the width of the conductor track narrow and still compensates for defects and imperfections.
- the invention is explained in more detail below with reference to 7 figures.
- Figure 1 The design of the gate electrode (2) shown here for a field effect transistor is a design optimized according to classic optimization methods from semiconductor technology.
- the gate electrode is adapted so that it is only in the active zone of the OFET. Any overlap with the inactive zone would cause parasitic capacitances that would negatively affect the switching frequency.
- the electrical connection 1 is indicated by an arrow.
- FIG. Part 4 of the electrode is thereby electrically insulated. This would result in a dramatic drop in the performance of the transistor. It is not possible to widen the electrode, as this would increase the parasitic effects again.
- FIG. 3 shows how the same defect can be avoided by means of the introduced support conductor track or cross-connection 5.
- Figures 4 and 5 show a design for geometrically compensating series resistances:
- Patterns with edges, as they occur on cuboids, are unsuitable for printing technology. These edges are germs for defects and they promote the bleeding of the patterns during printing.
- FIG. 7 shows the improved shape with rounded corners.
- Another aspect for printing is maintaining a distance from wide feed lines.
- the invention takes into account for the first time in the drafting of the layouts, designs and / or patterns for integrated circuits or OFETs the printing difficulties and the special features of organic electronics.
- Electrodes are preferably placed along a preferred direction of the printing process, which usually guarantees the best resolution. In particular, they can be arranged parallel to the path direction.
- the web direction is the direction in which the continuous belt runs the web of the continuous belt.
