- members used in known organic FETs can be applied.
- the method of the present invention for manufacturing a field effect transistor is the above-described method for manufacturing a laminated film of an organic semiconductor layer and an organic insulating layer (that is, the above manufacturing method including steps (i) and (ii) )including.
- the organic FET manufactured by this manufacturing method is one of the FETs of the present invention. It is.
- Example 1 an example in which a polythiophene derivative (poly (3-perfluorooctylthiophene)) is used as the first organic molecule and polystyrene is used as the second organic molecule will be described.
- Poly (3-perfluorooctylthiophene) shown in Fig. 3 synthesizes 3-perfluorooctylthiophene, and uses this as a starting material to synthesize 2,5-dibu-mouthed 3-perfluorooctylthiophene.
- the synthesis method of 3-perfluorooctylthiophene, 2,5 jib mouth mouth 3 perfluorooctylthiophene, and poly (3-perfluorooctylthiophene) is shown in this order.
- the unfiltered solid is placed in a Soxhlet extractor, and the monomers and salts are extracted with methanol, then the catalyst and oligomers are extracted with hexane, and finally the poly (3- Perfluorooctylthiophene) was extracted.
- the solvent was removed from the extracted chloroform solution by an evaporator to obtain solid poly (3-perfluorooctylthiophene).
- the coating solution was prepared using poly (3-perfluorooctylthiophene) as the first organic molecule, which is a semiconductor material, and polystyrene as the second organic molecule, which is an insulator material.
- 3-Perfluorooctylthiophene (3-perfluorooctylthiophene) monomer 2.
- OOg and polystyrene monomer styrene (4.00 g) were placed in a separatory funnel and stirred for 1 hour. Let stand for hours. After standing, the solution in the separatory funnel was separated into two layers. The specific gravity of 3-perfluorooctylthiophene is greater than that of styrene. Therefore, it can be assumed that the lower layer of the separated liquid is 3-perfluorooctylthiophene and the upper layer is styrene. These two liquids were carefully separated and weighed for each.
- the liquid weight of the upper layer was 4.00 g, and the liquid weight of the lower layer was 2.00 g. Since the weight of the upper and lower liquids is equal to that of styrene and 3-perfluorooctylthiophene before mixing, it can be assumed that these two liquids are not compatible. Therefore, it can be assumed that there is no compatibility between poly (3-perfluorooctylthiophene), which is a liquid polymer, and polystyrene.
- the poly (3 perfluorooctyl thiol off) was prepared so that the polystyrene was 3 wt%.
- the two materials and tetrahydrofuran were mixed so that the water content was 3 wt%, and the mixture was stirred for 1 hour to prepare the coating liquid (C1) of Example 1.
- the coating liquid (C1) was a transparent and uniform liquid. From this, it was confirmed that both polystyrene and poly (3-perfluorooctylthiophene) were dissolved in tetrahydrofuran.
- a chromium film having a thickness of lnm was formed on one side of a quartz glass substrate having a size of 50 mm square and a thickness of 0.5 mm, and a gold film having a thickness of lOOnm was formed thereon. These were formed by vacuum sputtering.
- the coating solution (C1) was applied to this substrate by spin coating.
- Spin coating was performed by dropping the coating liquid (C1) onto the substrate, rotating the substrate at 500 rpm for 5 seconds, and further rotating the substrate at 40 OOrpm for 30 seconds.
- the substrate coated with the coating liquid (C1) was dried at room temperature of 25 ° C. for 1 hour.
- a source electrode and a drain electrode having gold power were produced by vacuum electron beam evaporation using a shadow mask.
- the gate length was 100 m and the gate width was 3 mm.
- a polystyrene layer as a gate insulating layer and a poly (3-perfluorooctylthiophene) layer as a semiconductor layer were separately formed by a coating method to produce an organic FET.
- a chromium film and a gold film were formed on a quartz substrate.
- a black mouth form solution in which only 3 wt% of polystyrene was dissolved was spin-coated and then dried at room temperature of 25 ° C. for 1 hour.
- a perfluorooctane solution in which only 3 wt% of poly (3-perfluorooctylthiophene) was dissolved was spin-coated and dried at room temperature of 25 ° C. for 1 hour. Since polystyrene does not dissolve in perfluorooctane, the phenomenon of mutual dissolution, in which the polystyrene film dissolves into the solution during the application of the semiconductor material, did not occur.
- the spin coating conditions were the same as the spin coating conditions for the coating liquid (C1). Thereafter, a source electrode and a drain electrode were formed by using an electron beam evaporation method. In this way, a comparative FET was fabricated.
- the concentration distribution in the depth direction of the fluorine element, carbon element, and gold element in the film is secondarily determined. Determined by ion mass spectrometry (SIMS). The concentration distribution in the depth direction was determined by repeating the operations of measuring the element concentration on the film surface, then shaving the film surface by a certain amount by argon sputtering, and measuring the element concentration again.
- SIMS ion mass spectrometry
- the depth at the time of measurement was determined from the sputtering rate of argon sputtering (the thickness of the film scraped off within a unit time).
- the sputtering rate was calculated by the following method. First, the thickness of a single polystyrene film produced by spin coating was measured in advance with a film thickness meter, and then the time required to completely scrape the film under the same sputtering conditions as in SIMS measurement was measured. From the film thickness and the time required for sputtering, the thickness of the film that was scraped off by argon sputtering within a unit time was calculated. For the film of poly (3-perfluorooctylthiophene) alone, the sputtering rate was calculated by the same method.
- FIG. 4 is a graph showing the SIMS measurement results of the laminated film prepared with the coating liquid (C1).
- the horizontal axis of the graph represents the argon sputtering time
- the vertical axis represents the concentrations of fluorine, carbon, and gold elements.
- the element concentration on the vertical axis is normalized by the maximum value of each element. Since the amount of film scraped off by sputtering is proportional to the sputtering time, the sputtering time on the horizontal axis corresponds to the depth of the surface force of the film facing the inside of the film. Therefore, in the following description, for convenience, the surface of the film exposed by sputtering for t minutes is described as “depth for t”. As shown in Fig.
- the concentration of each element increases or decreases abruptly as the sputtering time elapses in the range 31 (4 to 10 minutes) and range 32 (14 to 17 minutes) in Fig. 4. But otherwise it was constant.
- the concentration of elemental fluorine decreased in range 31 to zero.
- the elemental carbon concentration increased in range 31 and decreased to 0 in range 32.
- the gold element concentration increased from 0 in the range 32 to a constant value.
- the sputtering time values at which the concentration of fluorine element, carbon element, or gold element is half the maximum value are 6 minutes, 16 minutes, and 16 minutes, respectively. Minutes.
- the fluorine element is derived from a constituent element of poly (3-perfluorooctylthiophene), and the carbon element is derived from a constituent element of both poly (3-perfluorooctylthiophene) and polystyrene.
- Gold is derived from a gold electrode formed on a quartz glass substrate. Considering these facts, the composition in the film was estimated as follows. [0088] After 14 minutes of argon sputtering, the gold element was detected, and the carbon element decreased accordingly. Therefore, it can be assumed that the film was removed by argon sputtering and the gold electrode of the substrate appeared on the surface.
- the concentration of gold and carbon elements did not change rapidly in a stepped manner with respect to changes in sputtering time.
- the shape of the film surface becomes uneven due to sputtering, and the film exists on the substrate surface.
- gold in the lower part appears on the surface in the concave portion of the film. Therefore, in this measurement, it is presumed that the formed film was completely removed by the sputtering in the half-life time of 16 minutes.
- the film formed in the example exists between 0 to 16 minutes in FIG. From the change in the elemental concentration of fluorine, it can be inferred that most of poly (3-perfluorooctylthiophene) is present up to a depth of 6 minutes, which is the half-life, and does not exist thereafter. On the other hand, the concentration of carbon element is considered to increase after the half-life of 6 minutes. If polystyrene is present at a depth of up to 6 minutes, similar to poly (3-perfluorooctylthiophene), the carbon element concentration should decrease at depths of 6 minutes and thereafter. On the contrary, it increased.
- the total thickness of the spin coat film is 170 nm, and the area from the film surface to a depth of about 50 ⁇ m. It was estimated that there was a poly (3-perfluorooctylthiophene) layer and a polystyrene layer in the region from a depth of around 50 nm to a depth of around 170 nm.
- the transistor characteristics were measured using Semiconductor 1 Parameter 1 Analyzer 1 4155B (Semiconductor Parameter Analyzer 4155B) (Agilent Technology). Specifically, a voltage of 80 V is stored between the source electrode and the drain electrode, the gate voltage is changed in the range of 50 to 50 V, and the current value between the source and drain is proportional to the square of the gate voltage. Thus, the carrier mobility was derived using the following equation.
- I Source-drain current.
- V Gate voltage.
- ⁇ Mobility.
- ⁇ Dielectric constant of vacuum.
- t thickness of the insulating layer.
- the mobility of the fabricated organic FET was 0.02 cm 2 ZVs, and the ratio of the ON current to the OFF current between the source and drain was 10 5 .
- FIG. 5 is a graph showing the SIMS measurement result of the spin coat film before forming the source / drain electrodes, as in FIG. 4, and shows the correlation between the sputtering time and the concentration of a predetermined element. .
- the shape of the graph in Fig. 5 is almost the same as the graph in Fig. 4, and only the region 41 (sputtering time: 4 to 7 minutes) where the fluorine element concentration and carbon element concentration change rapidly is the same as the graph in Fig. 4. Different.
- Range 41 in FIG. 5 was shorter than range 31 (4-10 minutes) in FIG. This indicates that the rate of change of the fluorine element concentration and the carbon element concentration in the film thickness direction in the film of FIG. 5 is larger than that of the film of FIG. This indicates that the boundary between the insulating layer and the semiconductor layer is clearer in the film of the comparative example formed by separately applying the gate insulating layer and the semiconductor layer than in the film of the example. Moreover, the mobility of the FET of the comparative example is 0.005 cm 2 ZVs, Compared with the case where the layer and the semiconductor layer were formed at the same time, it was lower.
- the gate insulating layer and the semiconductor layer could be produced at the same time.

In addition, the characteristics of the prepared organic FET were evaluated.
- the carrier mobility of the fabricated organic FET was 0.01 cm 2 / Vs, and the ratio of the ON current to the OFF current between the source and drain was 10 5 .

- the black mouth form solution in which Sulfier perfluorooctane amide-added pentacene was dissolved was applied on the polybutyl alcohol layer, mutual dissolution did not occur.
