The E-Wafer by ESTION is a wafer instrumented with embedded sensors, designed to measure electrostatic charges in real time during standard production. By integrating measurement directly into a 200 mm or 300 mm wafer, it provides in-situ insight throughout the full manufacturing process — not just at static test points.
Whether you’re running automated wafer fabs, developing process flows, or tracking electrostatic-induced defects, the E-Wafer unearths the hidden risks so you can improve yield, reduce particle build-up, and prevent electrostatic discharge events.
Embedded Electrostatic Sensors
Sensors are built into eight distinct regions of the wafer, measuring potential differences across its surface to detect charge accumulation and risky zones.Continuous In-Process Monitoring
Real-time data capture throughout handling, processing, and movement gives you a full picture of when and where charge builds up.
On-Board Logging & Wireless Access
Seamless Integration into Production
The E-Wafer is especially useful for:
Why It Matters
Electrostatic charge poses several serious risks during wafer manufacturing:
By exposing when and where these risks happen, the E-Wafer helps engineers to:
