As part of our continuous improvement process, we design upgrades to help our customers to improve the performance of their machines, reduce cost of ownership, and reach their sustainability goals.
Upgrades designed to improve your machine performance and boost the productivity of your operation
In our ongoing mission to improve our customers’ productivity and yield, we devised a series of solutions that enable our customers to reduce on-wafer particle contamination in semiconductor applications by using three on-tool technologies, our Anti-Recoil Technology, a Rotor Cup Cover, and the use of High Temperature Pumps.
During production, particles can recoil from the turbopump into the chamber, potentially contaminating the wafers and reducing productivity. Our Anti-Recoil technology significantly reduces particle contamination by letting them pass easily through the turbo pump into the exhaust.
Rotor Cup Cover
To prevent corrosion and particulate build up on the rotor cup (at the inlet of the turbo pump), we developed a corrosion resistant Rotor Cup Cover that prevents both the formation of deposition and the corrosion of the stainless steel-components.
High Temperature Pumps
Another source of particle contamination comes from deposition inside the turbo pump, which can also allow particles to travel back through the turbo pump and into the chamber. By using High Temperature Pumps the gas path is heated up to extremely high temperatures lessening the formation of deposition. These pumps have a special high heat emissivity coating on key vacuum components, such as the rotor and stator, and their temperature profile is continuously optimised for best results.
All three particle reduction technologies can be installed during a regular pump service at our Service Technology Centre to ensure costumers can optimise productivity for new equipent and their existing installed base.
The XCEDE’s Dry Pump protection technology prevents the corrosion of critical pump components and increases the meantime between service intervals, maximising costumer uptime. This technology outperforms all competing methods by using a complex combination of surface treatment and precision engineering to reduce the chemical and mechanical wear within the pump mechanism for Edwards iH, iXH and iXM pump families.
Upgrades designed to increase the meantime between service and increase the efficiency of your equipment fleet for a reduced Total Cost of Ownership.
Edwards developed the Porous Head, a field service upgrade that employs a sintered, porous, metal block, which evenly spreads an air purge across the surface to reduce the risk of powder accumulation. It replaces the traditional ceramic insulator head.
During the abatement process, solids, typically powders, can build up in unwanted areas of the system, such as the underside of the inlet head. This powder accumulation leads to a blockage that prevent the flow of process gases, causing frequent planned service interventions. In one year of severe processes, this powder build-up can cause more than nine service interruptions resultings in increased cost of ownership through labour and spare parts usage.
Customers using the Porous Head upgrade, have moved from ten service intervals per year to just two on average. This has removed an average of 64 hours of tool downtime per year for customers without a backup abatement system, resulting in $1.5million of additional throughput.
Customers with a back-up abatement system see substantial savings in spare parts, maintenance labour, and increased energy efficiency by reducing their dependency on their back up system.
Fleets with machinery that has been in use for more than five years risk unexpected failures in their critical electronics regardless of their mechanical performance, which is mainly preserved by effective maintenance regimes.
Edwards Life Services solution is a great option to refresh machinery and extend your fleet's lifetime. Life Services covers all the major system electronic parts with extended warranties, keeping your equipment running for years to come.
Life Services is available through our global network of Service Technology Centres.
Upgrades designed to increase the lifetime of your equipment fleet and its environmental impact to help you reach your sustainability targets.
Fab-wide cooling water contamination is a risk posed by abatement systems without rigorous maintenance schedules. In many systems, heat exchangers are vulnerable to corrosion damage from acidic process chemistry that can cause a leak into the Fab’s process cooling water. This contamination can damage other process tools that use the same cooling water circuit. It also poses a risk to the environment as it is hazardous to dispose of.
The heat exchanger field service upgrade kit is an effective solution that converts the existing brazed heat exchanger into a new plate and gasket design, without significant modification to the system. It provides improved resistance to acid attack when compared with original heat exchangers, offering an enhanced service life of around five to ten times and reducing the risk of Fab cooling water contamination.
