- Transistors can be chosen the smaller the thinner that
- Gate dielectric can be manufactured.
- the substrate compatibility is particularly important for a direct integration into the production process of a packaging Interest. If the packaging consists of paper or cellulosic fiber-containing materials, the polymer electronics should be able to be integrated directly onto this carrier material. However, paper generally has a very rough surface, so that its use as a substrate places high demands on the integration process.
- paper as a substrate for polymer ktr-on-i is proposed in EP 1 073 993 B1, but no specific method of implementation is specified. It is also known that paper is suitable as a substrate for the production of electrochromic displays or electrochemical transistors without details of the production being known.

- a surface coating of paper or another rough surface of a paper-containing substrate is possible, which e.g. integration of field effect transistors, in particular organic field effect transistors, is permitted.
- the advantage of the phenol-containing base polymer is a poly-4-vifylphenol, a poly-4-vinylphenol-co-methacrylic acid-2-hydroxyethyl ester and / or a poly-4-vinylphenol-co-methacrylic acid methyl ester.
- An advantageous embodiment of the invention has at least one crosslinker component, it being particularly advantageous if at least one crosslinker component is a di- or a tribenzyl alcohol compound, in particular 4-hydroxymethylbenzyl alcohol.
- At least one crosslinker component is a formaldehyde generator, in particular polyrnelamine-co-formaldehyde, and / or an electrophilic crosslinker system, in particular 4-hydroxymethylbenzyl alcohol and / or 4-toluenesulfonic acid. It is also advantageous if one embodiment is at least one electrophilic crosslinker component with one of the following compounds:
- R 2 alkyl having 1 to 10 carbon atoms or aryl It is also advantageous if a thermal acid generator is present in the solution, in particular a compound which can transfer a proton to the hydroxyl group of a benzyl alcohol, in particular 4-toluenesulfonic acid, at temperatures below 150 ° C.
- a thermal acid generator is present in the solution, in particular a compound which can transfer a proton to the hydroxyl group of a benzyl alcohol, in particular 4-toluenesulfonic acid, at temperatures below 150 ° C.
- Photo acid generator _ are used in the solution, in particular a photo acid generator which, after irradiation with UV light, generates a photo acid which furthermore causes the transfer of a proton to the hydroxyl group of a benzyl alcohol, in particular a sulfonium and / or an iodonium salt.
- An alcohol in particular n-butanol, and / or dioxane, N-methylpyrolidone (NMP), ⁇ -butyrolactone, xylene and / or propylene glycol monomethyl ether acetate (PGMEA) is advantageously used as the solvent.
- the best film properties are formed when the mass fraction of the solution is between 5 and 20%.
- the object is also achieved by a method having the features of claim 15.
- a method having the features of claim 15. The fact that the surface with a solution according to at least one of claims 1 to 14 in Is brought into contact, a polymer formulation is deposited on the surface from the solution, which smoothes the fibers of the surface, in the order of the layer thickness of the polymer film (100 to 500 nm).
- the polymer formulation is deposited flat and / or structured on the surface.
- Advantageous methods for applying the solution are spin coating, spray coating, printing and / or immersion processes.
- thermal crosslinking and / or photoinduced crosslinking of the polymer formulation is carried out on the surface. It is advantageous if thermal crosslinking is carried out at a temperature between 120 and 200 ° C.
- the object is also achieved by a semiconductor component, in particular an organic field-effect transistor, in which the substrate has a surface that is covered by a
- Method according to at least one of claims 15 to 19 is treated. It is advantageous if the substrate is a paper, in particular a smooth, hot-pressed, wood-free paper without easily soluble fillers. This enables particularly inexpensive semiconductor components to be produced.
- Fig. 4 drawing of a photo with a paper substrate for an integrated circuit; 5 output characteristic curve of a pentacene OFET on a paper substrate;
- Fig. 7 drawing of a characteristic curve of a 5-stage ring oscillator.
- Composite materials made of paper and plastic can be treated by the solution according to the invention and / or the method according to the invention, so that a semiconductor component can be arranged on the substrate.
- paper In contrast to other flexible substrates (e.g. plastic films), paper differs in that it is essentially made of cellulose-based fibers, which together with various fillers form a three-dimensional network. However, most are
- Papers Fiber structures present on the surface of the paper which means that the surface of the paper has a roughness which corresponds to the size of the cellulose fibers used (several micrometers) and the fibers themselves have a surface roughness of several show a hundred nanometers. This is shown in Figures 1A and 1B.
- Special papers are also known (photo glossy paper, inkjet paper) in which the surface roughness is reduced by means of film lamination.
- these film laminations are not resistant to process conditions, such as they are required in integrated circuits based on organic field effect transistors (temperature resistance up to 200 ° C,
- the roughness of the paper and the absorption of solvents (water, acetone, alcohols, etc.) and the associated swelling behavior of the paper prove to be problematic for the processing and integration of organic thin-film transistors and their total thickness (see Fig. 3 ) is between 200 nm and 1 ⁇ m and in which structure sizes of less than 5 ⁇ m (channel length - distance between source and drain contact) must be mapped correctly.
- solvents water, acetone, alcohols, etc.
- non-laminated papers are suitable, especially those that do not have easily soluble fillers, are wood-free and smooth (e.g. hot pressed).
- a polymer formulation is applied flat or structured to the paper surface.
- a formulation of poly-4-vinylphenol with a crosslinker component in an organic solvent eg alcohols, PGMEA.
- All formaldehyde generators for example polymelamine-co-formaldehyde methylated
- other electrophiles are generally suitable as crosslinker components
- Crosslinker systems e.g. 4-hydroxymethylbenzyl alcohol / 4-toluenesulfonic acid. 2 shows compounds that can serve as electrophilic crosslinkers.
- Chemically cross-link paper surface by supplying thermal energy (at 120-200 ° C) and thus form a thin polymer film on the surface of the paper, which is chemically resistant and smooth and allows organic thin-film transistors to be produced on it.
- This polymer layer also prevents swelling (penetration of solvent into the paper structure) of the paper.
- the polymer film is very thin (100 - 500 nm) and therefore does not affect the macroscopic properties of the paper (e.g. flexibility, color, etc.).
- photo-induced crosslinking systems (PAG + electrophilic crosslinking agents) are also suitable, it being possible to achieve photostructurability of the polymeric protective layer with these systems.
- Formulations of other phenol-containing base polymers are also possible for such applications.
- the following embodiments are mentioned as examples:
- all phenol-containing polymers and their copolymers such as poly-4-vinylphenol, poly-4-vinylphenol-co-methacrylic acid-2-hydroxyethyl ester or poly-4-vinylphenol-co-methacrylic acid methyl ester, are suitable as base polymers.
- 4-Hydroxymethylbenzyl alcohol or other di- or tribenzyl alcohol compounds are particularly suitable as crosslinking component.
- Suitable photo acid generators are in principle all compounds which, after irradiation with UV light, are able to generate a photo acid which furthermore causes the transfer of a proton to the hydroxyl group of the benzyl alcohol (e.g. sulfonium or iodonium salts ).
- An alcohol in particular n-butanol, and / or dioxane, N-methylpyrolidone (NMP), ⁇ -butyrolactone, xylene and / or propylene glycol monomethyl ether acetate (PGMEA) are suitable as solvents.
- Formulation 1 10% solution in PGMEA (100: 10: 2.5) A mixture of 2 g PVP (MW approx. 20,000) and 200 mg 4-hydroxymethylbenzyl alcohol are dissolved in 20.5 g PGMEA on a vibrator (about 3 hours). 50 mg of 4-toluenesulfonic acid are then added and the mixture is shaken for a further hour. Before use, the polymer solution is filtered through a 0.2 ⁇ m filter.
- Formulation 2 10% solution in PGMEA (100: 20: 2.5) A mixture of 2 g of PVP (MW approx. 20,000) and 400 mg of 4-hydroxymethylbenzyl alcohol are dissolved in 20.5 g of PGMEA on a vibrator (about 3 hours). 50 mg of 4-toluenesulfonic acid are then added and the mixture is shaken for a further hour. Before use, the polymer solution is filtered through a 0.2 ⁇ m filter.
