Diffraction-Based Overlay Metrology With Optical Convolution Layer
Overlay is a crucial indicator of manufacturing processing between layers. Currently, diffraction-based overlay (DBO) is widely adopted in overlay metrology. In response to existing challenges in DBO metrology, this study applied the concept of optical computing to establish a DBO metrology with an...
