17 de jul. de 2024 · This approach achieves the automatic leveling of Moiré fringes, addressing the issue of tilt between the mask and wafer, which impacts the phase analysis of the Moiré fringe.
Hace 3 días · moiré pattern, in physics, the geometrical design that results when a set of straight or curved lines is superposed onto another set; the name derives from a French word for “watered.”
17 de jul. de 2024 · A convolutional neural network (CNN) processes tilt images, and the DQN adjusts angles with high precision. Simulations showed angle measurement accuracy of 0.0011 degrees (horizontal) and 0.0043 degrees (vertical), enabling effective tilt correction. Overall, the manuscript is clearly written.
27 de jul. de 2024 · Moiré interferometry is a particular optical metrology based on the deformation of patterns, called moiré patterns, imprinted on an object. Hence, it is suitable for measuring physical properties of a deformable object due to its ability to detect the displacements of points.
21 de jul. de 2024 · This technique differs from traditional Moiré profilometry (MP) by using computer-generated fringes and a single-shot approach, which simplifies the equipment and enhances its suitability for real-time tasks.
17 de jul. de 2024 · During the alignment process based on the Moiré fringe method, a slight angular misalignment between the mask and wafer will cause the Moiré fringes to tilt, thereby affecting the alignment accuracy.
3 de ago. de 2024 · Scientists have hypothesized that moiré excitons — electron-hole pairs confined in moiré interference fringes that overlap with slightly offset patterns — may function as qubits in next-generation nano-semiconductors.
