Part of the Oxford Instruments Group
The PlasmaPro 100 Cobra ICP utilises high-density plasma to achieve fast etching and deposition rates. The process modules offer excellent uniformity, high-throughput, high-precision and low-damage processes for wafer sizes up to 200mm.
Our systems have a wide install base within high volume manufacturing (HVM), with well-developed process solutions. The PlasmaPro 100 Cobra supports a number of markets including, MEMS & sensors, GaAs & InP laser optoelectronics, SiC & GaN power electronics, and RF.
Wide temperature range electrode, -150°C to 400°C
The Cobra® ICP etching sources produce a high density of reactive species at low pressure. Substrate DC bias is independently controlled by an RF generator, allowing control of ion energy according to process requirements.
Oxford Instruments’ PlasmaPro 100 process modules offer a 200mm platform with single wafer and multi-wafer batch capability. The process modules offer excellent uniformity, high throughput and high precision processes.
Delivers reactive species to the substrate, with a uniform high conductance path through the chamber - Allows a high gas flow to be used while maintaining low pressure
Variable height electrode - Utilises the 3-dimensional characteristics of the plasma and accommodate substrates up to 10mm thick at optimum height
Wide temperature range electrode (-150°C to +400°C) which can be cooled by liquid nitrogen, a fluid re-circulating chiller or resistively heated - An optional blow out and fluid exchange unit can automate the process of switching modes
A fluid controlled electrode fed by a re-circulating chiller unit - Excellent substrate temperature control
RF powered showerhead with optimised gas delivery - Provides uniform plasma processing with LF/RF switching allowing precise control of film stress
ICP source sizes of 65mm, 180mm, 300mm - Delivers process uniformity up to 200mm wafers
High pumping capacity - Gives wide process pressure window
Wafer clamping with He backside cooling - Optimum wafer temperature control
