Manufacturing method of touch panel
A manufacturing method of a touch panel includes the steps of providing a substrate, forming a first conductive film on the substrate, forming a first mask on the first conductive film, etching the first conductive film to form electrode portions and lower intersect portions of the touch panel, forming an insulating film made of a negative resist on the first conductive film, and forming a contact hole above the electrode portion by removing the insulating film. The steps further include forming a second conductive film on the insulating film, forming a second mask on the second conductive film, etching the second conductive film to form an upper intersect portion connected between two adjacent electrode portions via the contact hole and intersecting with the lower intersect portion, and forming protective film on the second conductive film.

A method of manufacturing a semiconductor element includes forming a first silicon oxide film on a semiconductor wafer under a first film forming condition; forming a second silicon oxide film on the first silicon oxide film under a second film forming condition, a density of the second silicon oxide film being lower than a density of the first silicon oxide film; coating, with a photoresist, a region including the second silicon oxide film; exposing the photoresist using a photomask having an aperture and being disposed such that at least a portion of an edge of the aperture is disposed on the second silicon oxide film; removing a portion of the photoresist to form a photoresist pattern that has an overhang shape in a cross-section of the photoresist pattern; forming an electrode film on a region including the photoresist pattern; and performing lift-off by removing the photoresist pattern.
Integrated Assemblies
Some embodiments include methods of forming integrated assemblies. First conductive structures are formed within an insulative support material and are spaced along a first pitch. Upper regions of the first conductive structures are removed to form first openings extending through the insulative support material and over lower regions of the first conductive structures. Outer lateral peripheries of the first openings are lined with spacer material. The spacer material is configured as tubes having second openings extending therethrough to the lower regions of the first conductive structures. Conductive interconnects are formed within the tubes. Second conductive structures are formed over the spacer material and the conductive interconnects. The second conductive structures are spaced along a second pitch, with the second pitch being less than the first pitch. Some embodiments include integrated assemblies.

Wafers including a diamond layer and a semiconductor layer having III-Nitride compounds and methods for fabricating the wafers are provided.

Scalable graphene nanoribbon arrays for digital transistors
Methods for fabricating a graphene nanoribbon array in accordance with several embodiments of the present invention can include the steps of depositing PMMA dots on a substrate in an mn grid, to selectively seed graphene flakes on the substrate by controlling the growth of the graphene flakes on the substrate during the graphene deposition. The methods can further include the steps of masking the graphene flake edges with an insulator layer, at a very low deposition time or at a lower precursor concentration, to ensure there are not enough insulator molecules to form a complete layer over the flakes, but only enough insulator to form around the flakes edges. Once the graphene flake edges are masked, the bulk graphene can be etched, and the masking insulator can be removed to expose the resulting graphene nanoribbon.
