CIRIUS System

In semiconductor manufacturing, alongside line-width miniaturization, high stacking such as 3D NAND is advancing, and addressing internal defects that occur within devices has become a major challenge.

CIRIUS enables high-sensitivity inspection of internal defects with a proprietary optical system, and achieves identification of the depth position of internal defects through review and classification based on depth information.

This system makes it possible to non-destructively inspect and review internal defects that conventional inspection methods could not handle, contributing to early process improvement and manufacturing cost reduction in customers' production lines.
