  • Publication number: 20230266665
    Abstract: The present invention relates to a resist composition, especially for use in the production of electronic components via electron beam lithography. In addition to the usual base polymeric component (resist polymer), a secondary electron generator is included in resist compositions of the invention in order to promote secondary electron generation. This unique combination of components increases the exposure sensitivity of resists in a controlled fashion which facilitates the effective production of high-resolution patterned substrates (and consequential electronic components), but at much higher write speeds.

  • Publication number: 20220179319
    Abstract: The present invention relates to resist compostions, in particular to photoresists that can be used in photolithography, especially in the fabrication of integrated circuits and derivative products. The resist compositions of the invention include an anti-scattering component which has a significant amount of empty space, and thus fewer scattering centers, such that radiation-scattering events are more limited during exposure. Such anti-scattering effects can lead to improved resolutions by reducing the usual proximity effects associated with lithographic techniques, allowing the production of smaller, higher resolution microchips. Furthermore, certain embodiments involve anti-scattering components which are directly linked to the resist components, which can improve the overall lithographic chemistry to provide benefits both in terms of resolution and resist sensitivity.

  • Patent number: 10613441
    Abstract: The present invention relates to an electron beam (eBeam) resist composition, particularly an (eBeam) resist composition for use in the fabrication of integrated circuits. Such resist compositions include an anti-scattering compound which minimises scattering and secondary electron generation, thus affording extremely high resolution lithography. Such high resolution lithography may be used directly upon silicon-based substrates to produce integrated circuits, or may alternatively be used to produce a lithographic mask (e.g. photomask) to facilitate high-resolution lithography.

  • Publication number: 20180217033
    Abstract: The present invention relates to an imagable specimen sample, particularly an imagable histological sample for imaging via techniques such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The invention provides imaging preparation compositions, such as resin compositions, which can be embedded within a specimen sample and can also encapsulate the sample. The compositions contain either or both of a secondary electron generator and/or a self-healing component. The secondary electron generator enhances image quality by increasing the amount of secondary electron scattering. The self-healing component minimises specimen sample damage caused by the imaging technique.
