摘要: Systems and methods for custom photolithography masking via a precision dispense apparatus and process are disclosed. Methods include creating a toolpath instruction for depositing opaque onto a substrate, programming a precision dispense apparatus to execute the created toolpath instruction, and causing the precision dispense tool to deposit opaque material onto the substrate to form the photomask. The substrate may be an optically transparent plate or film or may be an electronic substrate where the opaque material is deposited directly onto a photoresist coating. Capabilities of the systems and methods disclosed herein extend to 3D substrates and custom photolithography masking, among others.

摘要: A photomask is used for scanning type projection exposure provided with a projection lens assembly composed of a lens assembly. A line width in a plurality of patterns of the photomask in a region to be transferred by performing scanning exposure including connecting portions of the lens assembly are corrected with respect to a line width of patterns which are the same as the patterns of the photomask present in a region to be transferred by performing scanning exposure but do not include the connecting portions.

摘要: A method including obtaining a measurement and/or simulation result of a pattern after being processed by an etch tool of a patterning system, determining a patterning error due to an etch loading effect based on the measurement and/or simulation result, and creating, by a computer system, modification information for modifying a patterning device and/or for adjusting a modification apparatus upstream in the patterning system from the etch tool based on the patterning error, wherein the patterning error is converted to a correctable error and/or reduced to a certain range, when the patterning device is modified according to the modification information and/or the modification apparatus is adjusted according to the modification information.

摘要: Examples of synchronized parallel tile computation techniques for large area lithography simulation are disclosed herein for solving tile boundary issues. An exemplary method for integrated circuit (IC) fabrication comprises receiving an IC design layout, partitioning the IC design layout into a plurality of tiles, performing a simulated imaging process on the plurality of tiles, generating a modified IC design layout by combining final synchronized image values from the plurality of tiles, and providing the modified IC design layout for fabricating a mask. Performing the simulated imaging process comprises executing a plurality of imaging steps on each of the plurality of tiles. Executing each of the plurality of imaging steps comprises synchronizing image values from the plurality of tiles via data exchange between neighboring tiles.

摘要: Embodiments described herein relate to apparatus and methods for removing one or more films from a photomask to create a black border and one or more pellicle anchor areas thereon. A photomask substrate is exposed by removing the one or more films in the black border and pellicle anchor areas. The black border prevents a pattern on the photomask from overlapping a pattern on a substrate being processed. To create the black border and pellicle anchor areas, a laser beam is projected through a lens and focused on a surface of the films. The films are ablated by the laser beam without damaging the photomask substrate.

摘要: A method includes providing a photomask having a patterned absorption layer over a substrate. The photomask is irradiated with a beam having a mixture of transverse electronic (TE) waves and transverse magnetic (TM) waves. The irradiating includes generating surface plasmonic polaritons (SPP) on a sidewall of the patterned absorption layer. The SPP is used to suppress the TM waves while reflecting the TE waves. A target substrate is exposed to TE waves.

摘要: The invention relates to a method and a device for characterizing a mask for microlithography. In a method according to the invention, structures of a mask intended for use in a lithography process in a microlithographic projection exposure apparatus are illuminated by an illumination optical unit, wherein the mask is imaged onto a detector unit by an imaging optical unit, wherein image data recorded by the detector unit are evaluated in an evaluation unit. In this case, for emulating an illumination setting predefined for the lithography process in the microlithographic projection exposure apparatus, the imaging of the mask onto the detector unit is carried out in a plurality of individual imagings which differ from one another with regard to the illumination setting set in the illumination optical unit or the polarization-influencing effect set in the imaging optical unit.
