IBE Marathon™ Grids

Marathon™ IBE Grids have a proven performance and reliability track record in volume production.

Marathon™ Ion Beam Etch Grids are the result of applying advanced principles of ion beam plasma theory to robust thermal-mechanical design. The grids are extremely stable over the operating range and provide excellent matching between grid sets.

Marathon™ IBE grids have the longest life and lowest cost of ownership in the industry. Through careful design and tolerancing, Marathon™ grids perform consistently from beginning to end of life. Highly stable grid-to-grid alignment minimizes grid plate erosion and contamination, providing stable and repeatable IBE processing. Their proven lifespan is two to three times longer than the nearest competitor in high-volume manufacturing.

Plasma-Therm can retrofit Marathon™ grid assemblies to existing legacy IBE sources. Retrofits includes source stabilization upgrades.

Source upgrades with grid retrofits

  • Upgrade source mounting rods for improved mechanical stability.
  • Upgrade RF coil position fingers for improved RF plasma repeatability.
  • Optional single-piece quartz plasma containment vessel eliminates plasma leaks, thereby enhancing uniformity and eliminating extended troubleshooting downtime.
