The present invention relates to an organic transistor comprising a conductive element which forms a drain; a conductive element which forms a source located away from the drain; a conductive element which forms a gate having a surface which faces the drain and a surface which faces the source; a semiconducting layer which is in contact with the drain and the source; and a dielectric layer located between, firstly, the gate and, secondly, the source and the drain with the dielectric layer having a dielectric permittivity which varies depending on its thickness. According to the invention, the dielectric layer comprises a layer of a first dielectric material having a dielectric permittivity of less than four in which there is formed, at least between said opposite-facing surfaces, a volume of a second material, said volume having an overall cross-section which tapers from gate towards the space between drain and source and in that the relative dielectric permittivity of the second material exceeds four.

摘要:
The invention relates to a method of depositing a layer of material onto the surface of an object, of the type comprising the deposition of a layer of solution of said material in a first liquid followed by the evaporation of the first liquid to form the layer of material. According to the invention, the method comprises the formation of a layer of a second liquid interposed between the object and the layer of solution, the second liquid being immiscible with the first liquid, of density greater than that of the first liquid and with an evaporating temperature higher than that of the first liquid.
摘要:
A method for producing at least one pattern on a top surface of a support made from a material presenting a first thermal conductivity comprises a step of arranging of a mask made from a material presenting a second thermal conductivity and comprising at least one recess having a shape corresponding to that of the pattern, in contact with a bottom surface of the support, the ratio of the first conductivity over the second conductivity being greater than or equal to 2, or smaller than or equal to ½, throughout the duration of the method. The method further comprises a step of depositing on the top surface a solution comprising a material designed to form the pattern, and a step of evaporating the solution.

A device forming a pressure sensor is provided. The device includes: a substrate made of electrical insulation material including a first reservoir, a second reservoir in communication with the first reservoir and of which two internal walls are each equipped with an electrode, and a flexible membrane made of an electrical insulation material, including a protuberance and secured to the substrate so as to enable movement of the protuberance between a position in which it is at a distance from a liquid filling the first reservoir and at least one second position in which it exerts a pressure on the liquid, thus discharging it at least partially from the first reservoir toward the second reservoir with mechanical contact with the two electrodes, the mechanical contact of the liquid with the electrodes establishing a resistance or capacitance between the electrodes. Application in the production of a touch screen is also provided.
摘要:
The method for making a hole in a layer includes the provision of first and second adhesion areas on a surface of a support. The first area has dimensions corresponding to the dimensions of the hole. The method includes depositing a layer on the first and second adhesion areas. The material of the layer has an adhesion coefficient to the first area lower than the adhesion coefficient to the second area. The part of layer arranged above the first area is eliminated by a fluid jet.
