20140139814 | Methods and Scatterometers, Lithographic Systems, and Lithographic Processing Cells - In a method of determining the focus of a lithographic apparatus used in a lithographic process on a substrate, the lithographic process is used to form a structure on the substrate, the structure having at least one feature which has an asymmetry in the printed profile which varies as a function of the focus of the lithographic apparatus on the substrate. A first image of the periodic structure is formed and detected while illuminating the structure with a first beam of radiation. The first image is formed using a first part of non-zero order diffracted radiation. A second image of the periodic structure is formed and detected while illuminating the structure with a second beam of radiation. The second image is formed using a second part of the non-zero order diffracted radiation which is symmetrically opposite to the first part in a diffraction spectrum. The ratio of the intensities of the measured first and second portions of the spectra is determined and used to determine the asymmetry in the profile of the periodic structure and/or to provide an indication of the focus on the substrate. In the same instrument, an intensity variation across the detected portion is determined as a measure of process-induced variation across the structure. A region of the structure with unwanted process variation can be identified and excluded from a measurement of the structure. | 05-22-2014 |

20110196646 | Alignment System, Lithographic System and Method - A lithographic system includes a lithographic apparatus comprising a projection system which projects a patterned radiation beam onto a target portion of a substrate and an alignment system which measures the position of a feature of the pattern on the substrate at a number of locations over the substrate. A controller compares the measured positions with points on a grid of values and extrapolates values for intermediate positions on the substrate based on values of corresponding intermediate points on the grid, so as to provide an indication of the intermediate positions on the substrate and their displacements relative to the grid. The grid is based on at least one orthogonal basis function, the measurement on the substrate being performed at positions corresponding to the root values of the at least one orthogonal basis function. | 08-11-2011 |

20110027704 | Methods and Scatterometers, Lithographic Systems, and Lithographic Processing Cells - In a method of determining the focus of a lithographic apparatus used in a lithographic process on a substrate, the lithographic process is used to form a structure on the substrate, the structure having at least one feature which has an asymmetry in the printed profile which varies as a function of the focus of the lithographic apparatus on the substrate. A first image of the periodic structure is formed and detected while illuminating the structure with a first beam of radiation. The first image is formed using a first part of non-zero order diffracted radiation. A second image of the periodic structure is foamed and detected while illuminating the structure with a second beam of radiation. The second image is formed using a second part of the non-zero order diffracted radiation which is symmetrically opposite to the first part in a diffraction spectrum. The ratio of the intensities of the measured first and second portions of the spectra is determined and used to determine the asymmetry in the profile of the periodic structure and/or to provide an indication of the focus on the substrate.

20110085176 | Method, Inspection Apparatus and Substrate for Determining an Approximate Structure of an Object on a Substrate - A system and method determine an approximate structure of an object on a substrate. This may be applied in model based metrology of microscopic structures to assess critical dimension or overlay performance of a lithographic apparatus. A scatterometer is used to determine approximate structure of an object, such as a grating on a stack, on a substrate. The wafer substrate has an upper layer and an underlying layer. The substrate has a first scatterometry target region, including the grating on a stack object. The grating on a stack is made up of the upper and underlying layers. The upper layer is patterned with a periodic grating. The substrate further has a neighboring second scatterometry target region, where the upper layer is absent. The second region has just the unpatterned underlying layers. | 04-14-2011 |
20110141450 | Method and Apparatus for Overlay Measurement - A method of measurement of at-resolution overlay offset may be implemented in a scatterometer. At least three targets are provided on a wafer, each target comprising a first marker grating and a second interleaved marker grating and each target having a different overlay bias between its first and second marker. The first and second markers are provided by subsequent lithography steps in a double patterning lithographic process. The targets are measured with a scatterometer and for each target a measured CD of at least one of the markers is determined using reconstruction. The CD of the first marker may be fixed in the reconstruction. The measured CDs and at least one of the overlay biases is used to determine an overlay result corresponding to a minimum measured CD. The overlay result may be determined by fitting a function such as a parabola to the measured CDs and the overlay biases and determining the overlay at the minimum of the fitted function. | 06-16-2011 |

20100083855 | METHOD AND APPARATUS FOR APPLYING A SHEET TO A SUBSTRATE - The invention provides a method and apparatus for laminating a sheet to a substrate in a stress free and distortion-less manner. The method comprises providing the sheet and substrate such that an attractive force between them exists that is capable of bringing the sheet and surface together at least when their distance is shorter than a critical distance. The method creates these conditions by locally making an initial contact between the sheet and substrate such that at a contact front, being the boundary between areas where the substrate and sheet are in contact and those where they are not in contact, these conditions exist. In a further step the sheet and substrate are allowed to gradually make contact such that the contact front advances along either of the substrate or sheet surface therewith increasing the contacting area between the substrate and the sheet. The method is advantages when used during imprint lithography or embossing processes or other processes where feature patterns need to be transferred from the substrate to the surface or vice versa. | 04-08-2010 |
