Abstract:
This disclosure describes a method for nano-patterning by incorporating one or more block copolymers and one or more nano-imprinting steps in the fabrication process. The block copolymers may be comprised of organic or organic components, and may be lamellar, spherical or cylindrical. As a result, a patterned medium may be formed having one-dimensional or two-dimensional patterns with a feature pitch of 5-100 nm and/or a bit density of at least 1 Tdpsi.
Abstract:
It is an object of the present invention to provide a method which can easily and selectively modify specific sites on indentations or protrusions of indentation/protrusion structures fabricated by nano-imprinting. Pressing a mold having indentation/protrusion structures onto a polymer substrate comprising at least two layers of different chemical composition exposes the second layer, which has been covered by the outermost layer, in pillars formed as a result of the pressing. Site-specific chemical modification of the pillars can be achieved by formulating a desired chemical composition for the second layer beforehand, or by chemical modification of the exposed second layer cross-sections in the pillars.
Abstract:
A method of preparing a polymer film having nanoscale features at the surface and being microstructured in its thickness over all or part of this film in accordance with a particular system including providing at least one block copolymer capable of being microstructured in accordance with the aforementioned particular system at a predetermined temperature and in accordance with at least one predetermined thickness, where the predetermined thickness corresponds to the thickness of the film all or part of which is compatible with the microstructuring in accordance with the particular system. At least one mould is provided capable of conferring the predetermined thickness and the nanoscale features after application to a film comprising the block copolymer. The mould is applied to a film including the block copolymer while heating the mould to the predetermined temperature, by which means the film is obtained and defined as an article.
Abstract:
There is provided fluorescent photopolymerizable resins for use in biological studies and image acquisition. In particular the photopolymerizable resins are useful in studying the properties of cells. The resins are also useful for the calibration of microscopic measurement systems.
Abstract:
This application describes a novel method of fabricating narrow (2-100 nm) width and long (greater than 50 micrometers and preferably 1 centimeter or longer) yet continuous hollow channels that allow flow of fluid or gas, or their combination. It can optimally include RIE pattern transfer or an optional sealing of a top surface over the channel. The invention also includes a novel method for making an imprint mold for imprinting the channel.
Abstract:
A method for producing a plurality of stamped shapes to serve as a mechanism for connecting and/or soldering or sealing a component, on a substrate, including the steps of depositing a layer made of a ductile material on the substrate and stamping the layer by means of an etched die having the plurality of etched portions defining one or more shapes to form the plurality of stamped shapes.
Abstract:
By forming metallization structures on the basis of an imprint technique, in which via openings and trenches may be commonly formed, a significant reduction of process complexity may be achieved due to the omission of at least one further alignment process as required in conventional process techniques. Furthermore, the flexibility and efficiency of imprint lithography may be increased by providing appropriately designed imprint molds in order to provide via openings and trenches exhibiting an increased fill capability, thereby also improving the performance of the finally obtained metallization structures with respect to reliability, resistance against electromigration and the like.
Abstract:
A method for producing a mechanism for connecting and/or soldering or sealing a component on a substrate, including depositing on the substrate a layer made of a ductile material which, if applicable, conducts electricity, and stamping the layer thus produced by means of an etched die, the etching depending on the shape that one wishes to give the mechanism for connecting and/or soldering.
