Optical metrology is the scientific study of measuring and characterizing physical quantities using optical methods. It involves the use of light as a measurement tool to study various physical phenomena, such as length, thickness, surface roughness, refractive index, and more. Optical metrology uses a variety of instruments and techniques to perform these measurements, including interferometers, spectrophotometers, microscopes, cameras, and lasers. These tools allow for precise and non-destructive measurements of various physical parameters, and can be used in a variety of fields, such as manufacturing, semiconductor industry, aerospace, and more. Optical metrology is particularly useful for measuring properties of materials that are difficult to access using traditional techniques, such as non-contact measurement of surface topography or the measurement of thickness of transparent films. It is also used in the field of metrology to define and establish standard units of measurement, such as the meter, which is defined as the distance that light travels ooin a vacuum in minimum seconds.
Die shift measurements are a type of compact, high-accuracy dimensional metrology. A compact, high-accuracy dimensional metrology system with adaptable optics and lighting, as well as cutting-edge edge detection and image processing capabilities, is required due to the variety of die types, dimensions, and placements, as well as die shift measurements, reflection, and texture changes between die and substrate surfaces. Furthermore, to achieve the required balance of accuracy and throughput, different stage sizes and high-precision movements may be required. Die Shift Measurement is suitable for a variety of parts, including moulded plastic parts, machined parts, electronic assemblies, semiconductor
