Optical wafer defect inspection at the 10 nm technology node and beyond

International Journal of Extreme Manufacturing, Год журнала: 2022, Номер 4(3), С. 032001 - 032001

Опубликована: Апрель 6, 2022

Abstract The growing demand for electronic devices, smart and the Internet of Things constitutes primary driving force marching down path decreased critical dimension increased circuit intricacy integrated circuits. However, as sub-10 nm high-volume manufacturing is becoming mainstream, there greater awareness that defects introduced by original equipment manufacturer components impact yield costs. identification, positioning, classification these defects, including random particles systematic are more challenging at 10 node beyond. Very recently, combination conventional optical defect inspection with emerging techniques such nanophotonics, vortices, computational imaging, quantitative phase deep learning giving field a new possibility. Hence, it extremely necessary to make thorough review disclosing perspectives exciting trends, on foundation former great reviews in methods. In this article, we give comprehensive topics past decade focus three specific areas: (a) detectability evaluation, (b) diverse systems, (c) post-processing algorithms. We hope, work can be importance both entrants people who seeking use interdisciplinary work.

The state-of-the-art in computer generated holography for 3D display

Deleted Journal, Год журнала: 2022, Номер 3(3), С. 1 - 1

Опубликована: Янв. 1, 2022

Holographic displays have the promise to be ultimate 3D display technology, able account for all visual cues. Recent advances in photonics and electronics gave rise high-resolution holographic prototypes, indicating that they may become widely available near future. One major challenge driving those systems is computational: computer generated holography (CGH) consists of numerically simulating diffraction, which very computationally intensive. Our goal this paper give a broad overview state-of-the-art CGH. We make classification modern CGH algorithms, we describe different algorithmic acceleration techniques, discuss latest dedicated hardware solutions indicate how evaluate perceptual quality summarize our findings, remaining challenges projections on future
