One embodiment provides a system for determining a process model for a photolithography process. The photolithography process can use multiple exposure-and-development steps to create features on a wafer. When the photolithography process exposes the wafer to a layout, the wafer can include topography variations which were caused by previous exposure-and-development steps. The process model can be used to predict patterns that are created on the wafer when the wafer is exposed to a second layout, wherein the wafer includes topography variations that were caused by resist features that were created when the wafer was exposed to a first layout. The process model can include a first term and a second term, wherein the first term is convolved with a sum of the first layout and the second layout, and wherein the second term is convolved with the second layout.

A method for modeling an environment with a risk of nuclear contamination comprising steps of: acquiring, using a detector (10) and through a 3-dimensional displacement of the detector in the environment, information related to the topography of the environment and radiological measurement data of the environment, and then via a computer processing unit (20), associating the radiological measurement data with location data in the environment, the location data having been deduced from path data of the detector, incrementially creating, using the information and via the computer processing unit: at least one matrix in which topographic data of the environment and the radiological data associated with the location data are compiled, and a 3-dimensional mapping representing the environment in which the topographic data and the radiological data are jointly represented.

The invention relates to an off-axis optical path three-dimensional microscopic topography measurement system. The system comprises an imaging object lens, an interference device and an image acquisition device. The interference device comprises a laser light source, a beam splitter prism, a first reflector, a second reflector, a fine adjustment reflector and a reference object lens. A laser lightbeam irradiates on the beam splitter prism via the first reflector and then outputs two light beams, the first light beam irradiates on a sample through an imaging object lens, and a reflected lightarrives at the image acquisition device via the imaging object lens and the beam splitter prism; the second light beam irradiates on the fine adjustment reflector via the second reflector and the reference object lens, the reflected light irradiates on the image acquisition device via the reference object lens, the second reflector and the beam splitter prism and forms a reference light, an off-axis angle of 1.52-7.57 degrees is formed between an object light and the reference light, thus, off-axis interference is formed, and an interference hologram is obtained through recording of the imageacquisition device. By optical path design, the system provided by the invention overcomes the difficulty that the conventional pre-magnified microscopic optical path optical wave curvature is difficult to adjust. The whole system is compact in structure and has high anti-noise ability.

A method for accelerating protein crystallization on a substrate is provided, including the steps of providing a coating layer comprising a colloidal solution containing inert particles on at least one discrete testing portion of a testing substrate to provide at least one coated portion, and drying the coated portion so that the coated portion has an enhanced surface topography defined by the characteristics of the coating layer. A supersaturated protein solution is applied to the coated portion, and the testing substrate is placed in an incubator for crystallization, and the growth rate of the protein crystals is accelerated during incubation due to the enhanced surface topography of the at least one coated portion. The testing substrate is evaluated to determine the degree of protein crystallization until crystallization in complete, and the protein crystals are subsequently removed from the testing substrate subjected to specific characterization testing.
