The scatterometric data that is used to find the value of the one or more parameter can be limited to those at wavelengths that are less sensitive to the underlying film characteristics. A model for a three-dimensional grating may be constructed by slicing a representative structure into a stack of slabs and creating an array of rectangular blocks to approximate each slab. One dimensional boundary problems may be solved for each block which are then matched to find a two-dimensional solution for the slab. A three-dimensional solution can then be constructed from the two-dimensional solutions for the slabs to yield the diffraction efficiencies of the three-dimensional grating. This model can then be used for finding the one or more parameters of the diffracting structure in scatterometry. Line roughness of a surface can be measured by directing a polarized incident beam in an incident plane normal to the line grating and measuring the cross-polarization coefficient. The value of the one or more parameters may then be supplied to a stepper or etcher to adjust a lithographic or etching process. | 2009-08-06 |

20090195859 | METHOD OF SPATIALLY SEPARATING WAVELENGTHS OF MULTI-WAVELENGTH SIGNAL USING ELECTRONICALLY CONTROLLED THERMAL STRUCTURE - A thin-film interference filter structure has a generally wavelength-dependent resonant response to incident optical energy in a predetermined range of wavelengths. The thin-film interference filter structure includes a thermally tunable layer having a thermally tunable optical characteristic such that a range of wavelength-dependent resonant optical responses of the thermally tunable layer are induced by a corresponding range of thermal conditions of the thermally tunable layer. The thin-film interference filter structure is configured to (1) receive a spatially varying pattern of thermal energy at the thermally tunable layer to impart a corresponding spatially varying pattern to the thermally tunable characteristic of the thermally tunable layer, and (2) receive the incident optical energy into the thermally tunable layer and output optical energy having spatial modulation corresponding to the spatially varying pattern of the thermally tunable characteristic. | 2009-08-06 |
