Nanoscale Device Characteristics Analysis System Nano-Prober NP8000
The Hitachi NP8000 is a SEM-based dedicated probing system designed to meet the analytical needs of 5 nm nodes and beyond. The system is capable of evaluating electrical characteristics, EBAC, EBIC, pulse IV, and the temperature requirements of nanoscale devices.
Overview
- New electron optics and new Schottky electron gun enable clear imaging using ultralow acceleration voltages of less than 100 V
- Improvement of EBAC image quality with high probe current
- 8 probe compatible
- Temperature-controlled stage for temperature-dependent characterization
- OM camera for both top-down and side views to assist coarse probing
- Sub-stage to allow samples to move independently from probes
- Probe exchange load-lock chamber
- EBAC (Electron Beam Absorbed Current) imaging function
- Improved voltage-applied EBAC function (dynamic-induced EBAC "DI-EBAC")
- Pulsed IV measurement for diagnosing resistive gate electronode defects (custom order)
Features
Integrated GUI for probe-position control and SEM imaging
Simultaneous display (top and side) ensures accurate positioning
Simultaneous display of SEM and EBAC images
A method for faster defect detection
Low-resistance defects have historically been hard to image. The NP8000 is equiped with a new Schottky electron gun and improved voltage-applied EBAC amplifier that allows for easy imaging of these defects.
Improved imaging capability at low-accelerating voltages allows for lower accelerating voltages to be used which reduces specimen damage during observation.
