Used Axcelis NV8250 High Energy Ion Implanter

The Axcelis NV8250 is a high-energy ion implanter designed for 200mm (8-inch) wafers, belonging to Axcelis’s classic NV series platform.

Core Positioning: A Dedicated Platform for High-Energy, Deep-Implant Processes

This system is specifically engineered for high-energy implantation processes, such as the formation of deep buried layers, retrograde wells, and deep isolation structures. It primarily serves the manufacturing of logic chips, CMOS image sensors (CIS), and power semiconductors on 200mm production lines, delivering high throughput while meeting stringent requirements for dose precision and implantation depth.

Key Technical Features

High-Energy RF Acceleration: Utilizing an RF (radio frequency) linear accelerator architecture, the system can accelerate ions to extremely high energy levels (in the MeV range), enabling ion implantation at depths of several microns to meet the doping requirements of specialized device structures.

Superior Energy Purity: Equipped with a high-precision mass-analysis magnet and an energy-filtering system, it effectively removes unwanted ion species and energy contaminants, ensuring precise control over implantation depth.

High Throughput and Automation: Featuring an efficient mechanical scanning mechanism and a fully automated wafer-handling system, the NV8250 supports SECS/GEM communication. It integrates seamlessly into automated high-volume production lines, providing stable, high-throughput performance.

Summary

With its high-energy RF acceleration technology, precise beam filtering, and reliable high-volume production capabilities, the NV8250 serves as a core tool for high-energy implantation processes—such as the creation of deep buried layers and retrograde wells—within 200mm manufacturing environments.
