CTI-Cryogenics 8116071G001 Enhanced On-Board 8F Cryopump – High-Productivity Sputtering Pump

The CTI-Cryogenics 8116071G001 Enhanced On-Board 8F Cryopump represents a significant advancement in cryogenic vacuum technology, specifically engineered to meet the demanding requirements of modern sputtering processes. In today's semiconductor manufacturing environment, tool availability is paramount. This enhanced cryopump directly addresses this need by dramatically reducing regeneration frequency while delivering superior vacuum recovery performance, enabling more wafers to be processed between maintenance intervals.

Designed as a direct replacement for existing On-Board 8F and Cryo-Torr 8F cryopumps, the 8116071G001 model offers seamless integration into both new process tools and existing installed equipment. Its enhanced capabilities are particularly beneficial for aluminum, titanium nitride (TiN), titanium, and other sputtering applications where consistent high-vacuum conditions are critical for film quality and process repeatability.

Key Performance Advantages

The primary differentiator of the Enhanced On-Board 8F Cryopump is its ability to maintain fast vacuum recovery performance over extended periods, directly reducing the number of regenerations required per month. In argon-based and nitrogen/argon-based sputtering processes, the pump sustains recovery to a target pressure of 1×10⁻⁷ Torr with exceptional consistency. This translates into a 40% to 65% reduction in regeneration frequency, meaning fewer interruptions to production and more predictable maintenance scheduling.

Importantly, the 8116071G001 maintains identical pumping speeds for all gases as the standard On-Board 8F and Cryo-Torr 8F models. This ensures that no process requalification is required when upgrading to the enhanced version, providing a risk-free path to improved performance.

Comprehensive Performance Specifications

The 8116071G001 cryopump delivers outstanding pumping speeds across a wide range of gases, making it suitable for diverse sputtering and vacuum process applications. Its key performance metrics include:

These specifications highlight the pump's exceptional capacity for handling high gas loads, particularly argon, which is commonly used in sputtering processes. The high water vapor pumping speed of 4000 l/s is critical for removing residual moisture that can degrade film quality and adhesion.

Enhanced Vacuum Recovery for Sputtering

Vacuum recovery is a critical step in sputtering processes, where the chamber must be pumped from process pressure down to a specified high vacuum level within a defined time after the feed gas is shut off. This recovery step is a primary driver of regeneration frequency. The Enhanced On-Board 8F Cryopump excels in this area by maintaining fast recovery performance for a significantly longer period compared to standard pumps.

For both argon-only and nitrogen/argon mixed processes (with more than 50% nitrogen), the 8116071G001 consistently achieves the target recovery pressure of 1×10⁻⁷ Torr with reduced degradation over time. This means that the pump can run for many more cycles before requiring regeneration, directly translating to higher tool availability and increased product wafer output.

As a result, process engineers can schedule regenerations to coincide with routine maintenance activities such as shield or target changes, eliminating the need for dedicated regeneration downtime. This operational synergy significantly improves overall equipment effectiveness (OEE).

Seamless Integration and Retrofit Capability

The 8116071G001 is designed for easy integration into all process tools currently equipped with either the On-Board 8F or Cryo-Torr 8F cryopumps. It can be installed at the factory for new process equipment or retrofitted in the field to existing installed tools. This backward compatibility ensures that semiconductor manufacturers can upgrade their vacuum systems without costly modifications to chamber interfaces or control software.

Installation is straightforward, and the pump's physical dimensions, mounting interfaces, and electrical connections are identical to its predecessors. This plug-and-play compatibility minimises installation time and allows for rapid deployment across multiple tools in a production environment.

FastRegen Option for Sputtering Applications

For applications requiring even faster turnaround during regeneration, the 8116071G001 can be specified with the FastRegen Control Module. This option reduces second-stage regeneration time to less than 1 hour, enabling quicker return to production for high-uptime sputtering operations. The FastRegen module is particularly valuable in high-volume manufacturing environments where every minute of downtime has a direct impact on wafer output.

Applications Beyond Sputtering

While optimised for sputtering processes, the Enhanced On-Board 8F Cryopump is also well-suited for other vacuum applications that require high pumping speed and low base pressures, including:

• Thin film deposition (PVD, CVD, ALD)

• Ion implantation

• Surface analysis (XPS, AES, SIMS)

• Space simulation chambers

• Particle accelerators and beamlines

Its robust construction and proven reliability make it a versatile choice for any high-vacuum system where uptime and consistent performance are critical.
