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.

An image forming apparatus has a micropattern reading unit, an encoded image generating unit and a code printing control unit. The micropattern reading unit reads a micropattern of a sheet. The encoded image generating unit generates an encoded image. The encoded image has the micropattern and a private key of a user. The code printing control unit prints the encoded image on the sheet to produce a certificate sheet.

Plural p-n junctions are formed in a waveguide such that they have junction interfaces in a normal direction to a surface of a substrate (to an extending direction of the substrate). Accordingly, a doping concentration changes in only a horizontal direction in the substrate, and it is possible to fabricate using the same processes as those for silicon electronic devices and to perform device fabricating at a low cost. Moreover, two or more junction interfaces are formed in the waveguide and thus an occupied area of the waveguide in a refractive index modulation region expands. Therefore, the efficiency of the refractive index modulation can be improved and a low-voltage operation is possible.

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:
Capacity-gate voltage characteristics of a field-effect transistor having plural gates are measured against a voltage change in each one of the gates for an inverted MOSFET and for an accumulated MOSFET, respectively. These measurements together with numerical simulations provided from a model for quantum effects are used to determine flat band voltages between the plural gates and a channel. Next, an effective normal electric field is calculated as a vector line integral by using a set of flat band voltages for the measured capacity as a lower integration limit. Lastly, mobility depending on the effective normal electric field is calculated from current-gate voltage characteristic measurements and capacity measurements in a source-drain path, and the calculated mobility is substituted into an equation for a current-voltage curve between source and drain.

The technique capable of reducing the power consumption in the MISFET by suppressing the scattering of the carriers due to the fixed charges is provided. A silicon oxynitride film with a physical thickness of 1.5 nm or more and the relative dielectric constant of 4.1 or higher is formed at the interface between a semiconductor substrate and an alumina film. By so doing, a gate insulator composed of the silicon oxynitride film and the alumina film is constituted. The silicon oxynitride film is formed by performing a thermal treatment of a silicon oxide film formed on the semiconductor substrate in a NO or N2O atmosphere. In this manner, the fixed charges in the silicon oxynitride film are set to 5×1012 cm−2 or less, and the fixed charges in the interface between the silicon oxynitride film and the alumina film are set to 5×1012 cm−2 or more.
