Definitions
- the invention relates to a field effect transistor in which there is at least one vertically oriented semiconductor column with a diameter in the nanometer range (nano-wire) between a source and a drain contact, which is surrounded by a gate contact in a ring while leaving an insulation distance, and a method for the same production.
- Thin-film transistors are known in which semiconductor material is applied to flexible substrates in a planar arrangement. Mechanical stress on the substrates, however, easily leads to the detachment of the semiconductors from the substrate or to other damage and thus to a functional failure.
- transistors on the nanometer scale by introducing ion trace channels into a film composite consisting of two plastic films and an intermediate metal layer, which are thus sensitized for subsequent etching.
- Semiconductor material is introduced into the etched-out microholes by means of electrode deposition or chemical bath deposition. Subsequent metallization of the top and bottom of the film composite forms source and drain contacts.
- the central metal layer serves as a gate contact.
- the cylindrical, vertical arrangement of these transistors has the advantage that they are mechanically very robust because the film is bendable or stretchable.
- the organic film material is also much softer than the inorganic semiconductor material. As a result, occurring bending, shear and pressure forces are almost completely absorbed by the film material, so that the transistor characteristic and other electrical parameters are largely constant under bending, flex and tensile forces.
- microholes can be made down to 30 nm and filled with semiconductor material, transistors can also be produced on a nanometer scale without lithography and without mask technology.
- the process Due to the type of deposition of the semiconductor material, the process produces polycrystalline semiconductor columns. The ratio of length to diameter of the semiconductor columns is also limited by the necessary crystal growth within the microholes. Overall, the process for producing the transistors is still too complex since the ion bombardment has so far only been possible in selected scientific institutions.
- the invention is based on the object of specifying a field effect transistor of the type mentioned at the outset, which can also be produced using monocrystalline semiconductor columns, it being intended to do without ion irradiation. For this purpose, a suitable simple, industrially applicable process for its production is to be demonstrated.
- the semiconductor columns are embedded in a first and a second insulating layer, between which there is a metal layer that leads outward as a gate contact.
- the ends of the metal layer which pass upwards through the second insulating layer are partly converted into an insulator or partly removed and filled up with an insulating material.
- Such a transistor can be manufactured using the following process steps: free-standing semiconductor columns are grown vertically on a conductive substrate,
- a first insulating layer is applied to the semiconductor columns
- the resulting layer body is etched so far that the portion of the first metal layer covering the semiconductor columns is removed again,
- a third insulating layer is applied to the layered body, whereupon the layered body is again etched flat, or the ends of the metal layer passing through to the surface of the layered body are converted into an insulator by oxidation or nitridation, and a second metal layer is finally applied to the layered body.
- the structure of the field effect transistor allows an extremely high packing density and extremely small dimensions without the need for lithographic methods.
- the substrates used can be firm or flexible.
- FIG. 1 shows the first method step for producing a field effect transistor according to the invention - growing the free-standing semiconductor columns on a metallically conductive substrate
- FIG. 3 shows the third and fourth method step - application of a first metal layer and a second insulating layer
- Fig. 6 shows the seventh method step - applying a second metal layer, finished structure of the transistor in cross section
- FIG. 7 shows a cross section of a transistor array that can be produced using the method.
- a disordered process can be used, as is known from the electrochemical growth of ZnO columns from IM.
- ZnO could also be applied by evaporating Zn or ZuO, see 121.
- a substrate can also be prepared in such a way that nucleation nuclei are formed in an orderly or disordered manner, at which column growth begins. Examples of disordered nucleation nuclei are Ni dots for the growth of ZnO columns 121 or Ni dots for the vertical growth of C60 nanotubes use, see 131, Fig. d.
- Ordered nucleation nuclei can be generated by lithographic methods, see 13 / or by non-lithographic ones, for example by dislocation steps on misaligned crystal surfaces. In the case of non-lithographically generated nucleation nuclei, the size restrictions imposed by the lithography largely disappear. The column growth is only determined by the size of the nucleation seed. Semiconductor columns can also be produced in etched ion trace channels from polymer films. If the film material is subsequently removed, free-standing semiconductor columns are also created, see IAI.
- the semiconductor columns (nanofibers / nanotubes) grown on substrates have so far mainly gained importance for the construction of components for electron field emission, luminescent diodes and solar cells with an extremely thin absorber layer.
- materials such as GaP, see / 5 /, InAs, InP, CdTe and others can also be used.
- an insulating layer 3 is applied, as shown in FIG. 2.
- the application can be by spin coating a polymer or by evaporation, CVD (Chemical Vapor Deposition) or other known methods for producing an insulating layer, such as an oxide or nitride.
- the insulating layer 3 also covers the side surfaces of the semiconductor columns 1.
- a first conductive metal layer 4, which later forms the gate contact of the transistor, is applied to the insulating layer 3 by sputtering, evaporation, CVD or a similar method.
- a further insulating layer 5 is then applied (FIG. 3) and the upper part of the resulting laminate is face-etched (FIG. 4). This can be done by a horizontal ion beam (ion beam etching) or by plasma or chemical or electrochemical etching processes, as are well known from semiconductor technology. Then the ends of the metal layer 4 which pass upward from the layer sequence are insulated (FIG. 5).
- the metal emerging on the surface can be converted into an insulator 6 by chemical oxidation or nitridation.
- a second metal layer 7 is applied (FIG. 6). This metal layer is in electrical contact with the semiconductor column and later acts as a source or drain contact.
- a channel 8 is formed on the outside of the semiconductor column 2, which, if the semiconductor column 2 is thin enough, can also extend over the entire thickness of the column.
- the gate contact surrounds the semiconductor columns 2 in a ring-shaped manner and is therefore coherent overall. All contacts (source, drain, gate) can be controlled as an array or subdivided using lithographic methods. Such arrays can be used in particular in circuits or displays. In the case of displays, a few hundred transistors are combined to form an optical pixel.
- the method enables the production of transistors with semiconductor columns in the order of 10 to 500 nm in diameter.
- the heights of the semiconductor columns are in the same range. With very small diameters, the transistor can be operated in the quantum regime.
