  • Publication number: 20130334579
    Abstract: A manufacturing method of an electrochemical sensor comprises forming a graphene layer on a donor substrate, laminating a film of dry photoresist on the graphene layer, removing the donor substrate to obtain an intermediate structure comprising the film of dry photoresist and the graphene layer, and laminating the intermediate structure onto a final substrate with the graphene layer in electrical contact with first and second electrodes positioned on the final substrate. The film of dry photoresist is then patterned to form a microfluidic structure on the graphene layer and an additional dry photoresist layer is laminated over the structure. In one type of sensor manufactured by this process, the graphene layer acts as a channel region of a field-effect transistor, whose conductive properties vary according to characteristics of an analyte introduced into the microfluidic structure.

  • Patent number: 8575005
    Abstract: A method of manufacturing an electronic device on a plastic substrate includes: providing a carrier as a rigid support for the electronic device; providing a metallic layer on the carrier; forming the plastic substrate on the metallic layer, the metallic layer guaranteeing a temporary bonding of the plastic substrate to the carrier; forming the electronic device on the plastic substrate; and releasing the carrier from the plastic substrate. Releasing the carrier comprises immersing the electronic device bonded to the carrier in a oxygenated water solution that breaks the bonds between the plastic substrate and the metallic layer.

  • Publication number: 20130071611
    Abstract: The disclosure relates to a three-dimensional integrated structure comprising a substrate and a plurality of projecting elements projecting from a flat surface thereof and obtained from a patterned and developed dry film photoresist. Advantageously, the three-dimensional integrated structure is highly defined, the projecting elements obtained by the patterned and developed dry film photoresist having a shape factor greater than 6. The three-dimensional integrated structure can be used to directly realize different type of electronic devices, such as microfluidic devices, microreactors or sensor devices.

  • Publication number: 20130048071
    Abstract: A thin film amorphous silicon solar cell may have front contact between a hydrogenated amorphous silicon layer and a transparent conductive oxide layer. The cell may include a layer of a refractory metal, chosen among the group composed of molybdenum, tungsten, tantalum and titanium, of thickness adapted to ensure a light transmittance of at least 80%, interposed therebetween, before growing by PECVD a hydrogenated amorphous silicon p-i-n light absorption layer over it. A refractory metal layer of just about 1 nm thickness may effectively shield the oxide from the reactive plasma, thereby preventing a diffused defect when forming the p.i.n. layer that would favor recombination of light-generated charge carriers.
