Carbon coater & thermal evaporator – high vacuum

K975X from Quorum Technologies

The K975X carbon coater is a compact thermal evaporator for vacuum deposition of thin layers of carbon and metals for SEM and TEM applications. The K975 series consists of the carbon and metal evaporator s K975X and  K975S, designed to coat 8” wafers or similarly large specimens with carbon (C). 

  • Unique ‘anti-stick’ carbon rod gun evaporation assembly
  • Built-in turbo pump
  • Suitable for specimens up to 140 mm² or 200 mm diameter
  • Rack-out drawer specimen loading system
  • Restricted or full vent control

Further information

The K975X is fitted with a carbon rod gun and metal evaporation insert. It can also be used for cleaning TEM and SEM apertures and for sputtering (optional sputter head insert). The chamber (borosilicate glass) is 250 mm in diameter x 300 mm length and can accommodate specimens up to 8"/200 mm in diameter. An easy rack-out specimen loading system provides comfortable access. A flat 80 mm stage is standard, but can be exchanged for optional holders like the 3 mm grid holder, the low-angle shadowing attachment or rotary planetary stage. For quick specimen exchange without removing the glass chamber, the rotary stage is mounted on a sliding access port on the side of the chamber. The flat stage can be tilted from 0° to +/- 180° for rotary shadowing techniques.

K975S Thermal Evaporator
The K975S is based on the K975X. It features a special load lock door which allows loading wafers up to 8"/200 mm. Please contact us for more information.
