摘要:
The present invention relates a method of producing a data storage medium comprising the steps of: a) coating a layer comprising a polymer material onto at least a part of a template surface thereby to obtain a modified template surface; b) clamping the modified template surface produced in step (a) with a target surface thereby to obtain an assembly; and c) introducing a liquid to an environment of the assembly obtained in step (b) thereby to transfer the layer comprising the polymer material of the modified template surface onto at least an adjacent region on the target surface.

An arrangement for a laboratory room that is confined by a floor, a ceiling and walls connecting the floor with the ceiling, the arrangement comprises: a main base suspended on the floor; a tool base arranged on the main base; a platform arranged around the tool base, wherein the platform is permeable for air, and the platform is suspended at the walls; an air inlet arranged below the platform; an air outlet arranged above the tool base; and air guides for directing an air flow upwards at least partially parallel to the main base and/or the tool base.
摘要:
The present invention relates to a method of reducing the wear of a tip of a probe when the tip is in contact with a surface of a substrate and when the probe is mounted on a support structure. A method is provided where a load force is applied to the probe, thereby causing the tip to be maintained substantially in contact with the substrate surface and a modulation step where the e magnitude of the load force is modulated at a modulation frequency. The modulation frequency is selected to be greater than a fundamental vibration frequency of the support structure on which the probe is mounted.

The present invention is directed to a method for producing a data storage medium on a surface of a substrate for storing data in the form of topographic features. The method comprises a first step wherein a crosslinking agent containing at least three alkyne groups is deposited on the surface of the substrate. In a second step the deposited cross linking agent is cured so as to obtain the data storage medium in the form of a crosslinked polymeric layer on the surface of the substrate. The invention is further directed to a data storage medium obtained by this method and a data storage device comprising this data storage medium
摘要:
A resist medium in which features are lithographically produced by scanning a surface of the medium with an AFM probe positioned in contact therewith. The resist medium comprises a substrate; and a polymer resist layer within which features are produced by mechanical action of the probe. The polymer contains thermally reversible crosslinkages. Also disclosed are methods that generally includes scanning a surface of the polymer resist layer with an AFM probe positioned in contact with the resist layer, wherein heating the probe and a squashing-type mechanical action of the probe produces features in the layer by thermally reversing the crosslinkages.
摘要:
The invention concerns a method for patterning a surface of a material. A substrate having a polymer film thereon is provided. The polymer is a selectively reactive polymer (e.g. thermodynamically unstable): it is able to unzip upon suitable stimulation. A probe is used to create patterns on the film. During the patterning, the film is locally stimulated for unzipping polymer chains. Hence, a basic idea is to provide a stimulus to the polymeric material, which in turn spontaneously decomposes e.g. into volatile constituents. For example, the film is thermally stimulated in order to break a single bond in a polymer chain, which is sufficient to trigger the decomposition of the entire polymer chain.
摘要:
Probe-based methods for patterning a surface of a material are described. In particular, high resolution patterning of molecules on a surface of a material, such as nano-scale patterns with feature sizes of less than 30 nanometers, are described. In one aspect, a method for patterning a surface of a material includes providing a material having a polymer film. A heated, nano-scale dimensioned probe is then used to desorb molecules upon interacting with the film. The film includes a network of molecules (such as molecular glasses) which are cross-linked via intermolecular (noncovalent) bonds, such as hydrogen bonds.
