Beneq C2

Automated batch wafer ALD equipment for high volume manufacturing

Beneq C2™ is the automated wafer solution in Beneq’s Cluster-compatible equipment portfolio. It offers a unique combination of high capacity batch processing and standard cassette-to-cassette automation..

Beneq C2 wins Compound Semiconductor High Volume Manufacturing Award

Beneq C2 is perfectly suited for high volume manufacturing in various wafer-based applications, including MEMS, LED, OLED, ink-jet print heads and more. The thermal batch ALD process of Beneq C2 is ideal for oxide and nitride processes used for dielectric, conductor, barrier and passivation purposes.

Beneq C2 equipment is available both as a single-wafer version and as batch-processing equipment.

Process details:

  • Up to 200 mm wafers in diameter
  • 20 000 wafers per month (10 nm of Al2O3 ALD coating on 200 mm wafers).
  • Face-down and face-up processing options.
