摘要:
The present invention relates to a multi-stack optical information carrier for recording information by means of an optical beam, said optical information carrier comprising—a substrate layer (S),—at least two recording stacks each comprising a recording layer (P1-P7),—at least one spacer layer (R) separating the at least two recording stacks, and—a cover layer (C). In order to improve the sensitivity during writing it is proposed according to the present invention that the recording layers (P1-P7) include a thermochromic material having temperature-dependent optical characteristics for selectively improving the sensitivity of the addressed recording layer (P1-P7) during recording and/or read-out.

A method is disclosed involving depositing a neutral orientation template layer onto a substrate after formation of chemical epitaxy or graphoepitaxy features on the substrate, but before deposition and orientation of a self-assemblable polymer. The orientation layer is arranged to bond with the substrate but not with certain features, so that it may be easily removed by vacuum or rinsing with organic solvent. The neutral orientation layer has a chemical affinity to match that of blocks in the self-assemblable polymer so that blocks of differing types wet the neutral orientation layer so that domains in the self-assembled polymer may lie side by side along the substrate surface, with interfaces normal to the substrate surface. The resulting aligned and oriented self-assembled polymer may itself be used as a resist for device lithography of the substrate.

Apparatus for producing thin layers of a fluid sample for analysis, has a two dimensional array of analysis chambers (45), and a branching pattern of entry channels (25) coupled to the array to enable the analysis chambers to be filled in parallel. The analysis chambers are planar with a height less than that of the entry channels so as to produce the thin layers when filled with the fluid sample. The array enables more spacers between chambers in a given area, so that variations in height of the chambers can be reduced, while still enabling fast filling of the chambers. The analysis chambers can be suitable for capillary filling by a specified fluid sample such as blood. A pattern of exit channels (35) can be coupled to the array. The entry and exit channels can form comb patterns, fingers of the comb patterns being interdigitated, and the analysis chambers being arranged between the interdigitated fingers of the comb patterns.

A BCP having first block of first monomer and second block of second monomer, adapted to undergo a transition from disordered state to ordered state at a temperature less than TOD, further including a bridging moiety having a functional group to provide hydrogen bonding between bridging moieties of adjacent first and second BCP molecules when in the ordered state and at a temperature in excess of a glass transition temperature Tg for the BCP. Composition including BCP comprising first block of first monomer and second block of second monomer, and a crosslinking compound having first and second terminal groups joined by a central moiety and arranged to crosslink second blocks of adjacent first and second BCP molecules by providing non-covalent bonding between the terminal groups and a functional group of the second monomer of the second blocks when the BCP is in the ordered state.

Treatment of a layer comprising self-assemblable polymer at a surface of a substrate is disclosed. In an embodiment, the treatment includes arranging a zone of temperature change to sweep across the layer, wherein a temperature of the layer within the zone differs from an initial temperature of the layer prior to passage of the zone.
摘要:
A block copolymer, adapted to self-assemble to form an ordered pattern on a substrate, has first and second blocks with a terminal moiety covalently bonded to the end of the first block. The molecular weight of the terminal moiety is 20% or less than that of the block copolymer and the terminal moiety has a low chemical affinity for the first block. The terminal moiety can assist the accurate positional placement of the domains of the ordered array and lead to improved critical dimension uniformity and/or reduced line edge roughness. The polymer may be useful in combination with a graphoepitaxy template, where the terminal moiety is chosen to associate with a sidewall of the template. This may reduce undesired aggregation of polymer domains at a sidewall and/or assist in domain placement accuracy.

A method for providing an ordered polymer layer at a surface of a substrate includes depositing a self-assemblable polymer layer directly onto a primer layer on a substrate to provide an interface between the self-assemblable polymer layer and the primer layer, and treating the self-assemblable polymer layer to provide self-assembly into an ordered polymer layer, such as a block copolymer, having first and second domain types at the interface. The primer layer is adapted to improve its chemical affinity to each domain type at the interface, in response to the presence of the respective domain type in the self-assembled polymer at the interface during the self-assembly of the self-assemblable polymer layer into the ordered polymer layer. This may lead to reduction in defect levels and/or improved persistence length for the ordered polymer layer. The method may be useful for forming resist layers for use in device lithography.
