摘要： When a thin film transistor is manufactured by using a printing method, the precision of alignment between a first electrode and a second electrode becomes a problem. If it is manufactured by using photolithography, a photomask for each layer is necessary, resulting in the cost being increased. The essence of the present invention is that not only processing the gate shape is carried out over the substrate by using a resist pattern formed by exposing using a photo-mask for the gate pattern but also processing the source-drain electrodes is carried out by lifting-off. As a result, alignment between the source-drain electrode and the gate electrode is carried out.

摘要： A method of manufacturing a semiconductor device having an organic semiconductor film comprises a step of preparing a transparent substrate at least having an opaque gate electrode and a gate insulator thereover, a step of forming a layer containing metal-nano-particles as a conductive layer for a source electrode and a drain electrode to the thus prepared transparent substrate, a step of applying exposure to the transparent substrate on the side of a surface not mounted with the opaque gate electrode, a step of flushing away a portion other than the source electrode and the drain electrode in the layer containing the metal-nano-particles after the exposure, and a step of forming an organic semiconductor layer forming a channel portion. Lower and upper electrodes are positioned in self-alignment manner and thus no positional displacement occurs even if a printing method is used. Accordingly, semiconductor devices such as flexible substrates using an organic semiconductor can be manufactured inexpensively by using a printing method.

摘要： The silicon wires formed around metal particles by crystal growth have the problem of metal pollution. For its solution, in the present invention, a silicon bridge is formed through standard silicon processes such as the lithography and the wet etching using hydrofluoric acid performed to an SOI substrate. Thereafter, a thermal oxide film is desirably formed at a high temperature to form a high-quality gate insulating film. It is also desirable to form a coaxial gate electrode. Then, after burying the bridge sections of the silicon bridge in a resist film, the silicon on the bridge girders is removed, and thereafter, the silicon wires buried in the resist film are collected. In this manner, the silicon wires can be collected without dispersing into the hydrofluoric acid solution. Then, a transistor using the silicon wires as a channel is formed.

摘要： Since positional displacement occurs in a case of using a printing method, an electrode substrate in which a lower electrode and an upper electrode are accurately positioned by way of an insulator could not be formed. Use of a photomask for positional alignment increases the cost outstandingly. According to the present invention, since the lower electrode is utilized as a photomask for positionally alignment with the upper electrode, positional displacement does not occur even by the use of the printing method. Accordingly, a semiconductor device such as a flexible substrate using the organic semiconductor can be formed at a reduced cost by using a printing method.
