High-Precision Wafer Bonding Alignment Mark Using Moiré Fringes and Digital Grating
This paper investigates a moiré-based mark for high-precision wafer bonding alignment. During alignment, the mark is combined with digital grating, which has the benefits of high precision and small size. A digital grating is superimposed on the mark to generate moiré fringes. By performing a phase...
