Abstract: The present invention provides a multi-layer organic memory device that can operate as a non-volatile memory device having a plurality of stacked and/or parallel memory structures constructed therein. A multi-cell and multi-layer organic memory component can be formed with two or more electrodes having a selectively conductive media between the electrodes forming individual cells, while utilizing a partitioning component to enable stacking of additional memory cells on top of or in association with previously formed cells. Memory stacks can be formed by adding additional layers—respective layers separated by additional partitioning components, wherein multiple stacks can be formed in parallel to provide a high-density memory device.

Abstract: A process for forming sub-lithographic features in an integrated circuit is disclosed herein. The process includes modifying a photoresist layer after patterning and development but before it is utilized to pattern the underlying layers. The modified photoresist layer has different etch rates in the vertical and horizontal directions. The modified photoresist layer is trimmed with a plasma etch. A feature included in the trimmed photoresist layer has a sub-lithographic lateral dimension.

Abstract: An exposure section of a 193 nm photolithography system is purged with a purge gas containing substantially no oxygen, such as nitrogen or an inert gas. This prevents oxidation of photoresist by photo-induced oxygen species that are produced in conventional 193 nm systems purged by clean dry air. A scanner and a stepper of the system are preferably calibrated to the optical properties of the purge gas. A protective layer may be provided over the photoresist to further protect the photoresist.

Abstract: A process for forming sub-lithographic features in an integrated circuit is disclosed herein. A process for enhancing the etch trimmability and the etch stability of features patterned on a photoresist layer is also disclosed herein. The process includes curing a photoresist layer after patterning and development but before an etch process is performed thereon. By controlling the formation of the cured portions of the features patterned on the photoresist layer, the features can be trimmed to sub-lithographic critical dimensions without pattern deformation or occurrence of other failure mechanisms.

Abstract: An integrated circuit fabrication process for patterning features at sub-lithographic dimensions is disclosed herein. The process includes sequentially exposing a of a film of arylalkoxysilane with a photobase generator, and catalytic amount of water coated on top of a conventional lipophilic photoresist layer provided over a substrate and exposed to a radiation at a first and a second lithographic wavelengths. The first lithographic wavelength is shorter than the second lithographic wavelength. Exposure to the first lithographic wavelength causes a self-aligned mask to form within the photoresist layer.

Abstract: A process for preventing deformation of patterned photoresist features during integrated circuit fabrication is disclosed herein. The process includes stabilizing the patterned photoresist features by a flood electron beam before one or more etch processes. The stabilized patterned photoresist features resist pattern bending, breaking, collapsing, or deforming during a given etch process. The electron beam stabilization can be applied to the patterned photoresist features a plurality of times as desired.

Abstract: An integrated circuit fabrication process to pattern features having reduced pitch is disclosed herein. The process includes reducing the width of a developed exposed area of a patterned photoresist layer provided over a substrate before patterning the substrate. The process further includes additionally patterning the patterned photoresist layer using the previously used mask or reticle to form a first feature and a second feature. The distance between adjacent first and second features is smaller than the distance between either of adjacent first features or adjacent second features.

Abstract: An integrated circuit fabrication process to pattern reduced feature size is disclosed herein. The process includes reducing the width of a patterned area of a patterned photoresist layer provided over a substrate before patterning the substrate. The patterned area is representative of a feature to be formed in the substrate. The width of the feature is reduced by an electron beam mediated heating and flowing of select areas of the patterned photoresist layer.

Abstract: A damascene structure and method of making the same in a low k dielectric material employs an imageable layer in which the damascene pattern is provided. The imageable layer is an alicyclic polymer into which silicon is incorporated by liquid silylation, for example. The silicon-rich regions are converted upon exposure to the plasma etch that etches the low k dielectric material into a hard mask containing silicon dioxide, for example. The low k dielectric material is protected from further etching by the mask thus created.
