Patent number: 9720326Abstract: A method of making a relief image printing element from a photosensitive printing blank is provided. A photosensitive printing blank with a laser ablatable layer disposed on at least one photocurable layer is ablated with a laser to create an in situ mask. The printing blank is then exposed to at least one source of actinic radiation through the in situ mask to selectively cross link and cure portions of the photocurable layer. Diffusion of air into the at least one photocurable layer is limited during the exposing step and preferably at least one of the type, power and incident angle of illumination of the at least one source of actinic radiation is altered during the exposure step. The resulting relief image comprises a plurality of dots and a dot shape of the plurality of dots that provide optimal print performance on various substrates, including corrugated board.Type: GrantFiled: February 26, 2010Date of Patent: August 1, 2017Inventors: David A. Recchia, Timothy Gotsick, Ryan Vest

Projection exposure system for microlithography and method of monitoring a lateral imaging stability
Patent number: 9720328Abstract: A projection exposure system (10) for microlithography. The system includes projection optics (12) configured to image mask structures into a substrate plane (16), an input diffraction element (28) which is configured to convert irradiated measurement radiation (21) into at least two test waves (30) directed onto the projection optics (12) with differing propagation directions, a detection diffraction element (34; 28) which is disposed in the optical path of the test waves (30) after the latter have passed through the projection optics (12) and is configured to produce a detection beam (36) from the test waves (30) which has a mixture of radiation portions of both test waves (30), a photo detector (38) disposed in the optical path of the detection beam (36) which is configured to record the radiation intensity of the detection beam (36), time resolved, and an evaluation unit which is configured to determine the lateral imaging stability of the projection optics (12) from the radiation intensity recorded.Type: GrantFiled: January 11, 2016Date of Patent: August 1, 2017Assignee: Carl Zeiss SMT GmbHInventors: Matthias Manger, Armin Rauthe-Schoech, Ulrich Mueller -
Patent number: 9720329Abstract: The invention concerns a projection objective of a microlithographic projection exposure apparatus designed for EUV, for imaging an object plane illuminated in operation of the projection exposure apparatus into an image plane. The projection objective has at least one mirror segment arrangement comprising a plurality of separate mirror segments. Associated with the mirror segments of the same mirror segment arrangement are partial beam paths which are different from each other and which respectively provide for imaging of the object plane (OP) into the image plane (IP). The partial beam paths are superposed in the image plane (IP). At least two partial beams which are superposed in the same point in the image plane (IP) were reflected by different mirror segments of the same mirror segment arrangement.Type: GrantFiled: March 15, 2016Date of Patent: August 1, 2017Assignee: Carl Zeiss SMT GmbHInventors: Hartmut Enkisch, Stephan Muellender, Hans-Juergen Mann, Rolf Freimann

Patent number: 9720330Abstract: Methods of micro- and nano-patterning substrates to form transparent conductive electrode structures or polarizers by continuous near-field optical nanolithography methods using a roll-type photomask or phase-shift mask are provided. In such methods, a near-field optical nanolithography technique uses a phase-shift or photo-mask roller that comprises a rigid patterned externally exposed surface that transfers a pattern to an underlying substrate. The roller device may have an internally disposed radiation source that generates radiation that passes through the rigid patterned surface to the substrate during the patterning process. Sub-wavelength resolution is achieved using near-field exposure of photoresist material through the cylindrical rigid phase-mask, allowing dynamic and high throughput continuous patterning.Type: GrantFiled: April 15, 2013Date of Patent: August 1, 2017Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventor: Lingjie Jay Guo
