Nikon Announces Upcoming Release of AMI-5700 Automatic Macro Inspection System

Enables batch inspection and measurement across entire 300 mm wafer area

Tokyo, Japan – October 21, 2021 – Nikon Corporation (President: Toshikazu Umatate, Minato-ku, Tokyo) is pleased to announce the upcoming release of the AMI-5700 automatic macro inspection system, which performs batch inspection of 300 mm wafers with exceptional sensitivity and maximized productivity.

Nikon automatic macro inspection equipment (the AMI series) are inspection systems that detect semiconductor wafer defects, and the industry-leading AMI-5700 provides ultra-fine sensitivity and superior throughput using simultaneous capture of images across the entire wafer. Many AMI systems are operating in 300 mm wafer manufacturing facilities worldwide, contributing to early detection of wafer defects that can occur in semiconductor mass production processes.

Like previous-generation AMI systems, the AMI-5700 (to be released in early November 2021) delivers very efficient, advanced inspection capabilities. The leading-edge AMI-5700 is not limited to wafer inspection though, it can also measure the wafer and detect defects. In addition to performing 180 wafers per hour (300 mm full wafer) inspection, a newly developed optional high-speed measurement function enables the AMI-5700 to also measure pattern linewidth, coating thickness, and focus at a rate of 100,000 or more points/min (Note 1). The AMI-5700 also features 3 load ports for wafer carriers to reduce transfer wait time in the fab and increase production efficiency. The AMI-5700 helps users better manage their semiconductor device production processes and boosts productivity of their semiconductor fabs.

The 5700 also features newly developed optics and an enhanced condensed mirror that enable high-quality image capture with low chromatic aberration. The AMI-5700 detects errors greater than or equal to ±10% of the target pattern sizes: 22 nm for lines/spaces, 50 nm for holes (Note 2) and 80 nm for spaces using diffraction inspection. In addition, the innovative scatter inspection unit enables exceptional detection sensitivity, with the AMI-5700 capable of detecting particles and scratches as small as 5 µm compared to 15 µm using earlier models.

Nikon is committed to providing industry-leading inspection solutions like the AMI-5700 that enable customers to advance semiconductor manufacturing and support the digital transformation.
