Quantemol-VT


Quantemol-Virtual Tool (Q-VT) is an expert software system for the simulation of industrial plasma processing tools. Q-VT builds upon the comprehensively validated Hybrid Plasma Equipment Model (HPEM) codes developed by renowned plasma physicist Professor Mark Kushner for simulating non-equilibrium low pressure (< 1Torr) plasma processes. Q-VT includes an intuitive user interface, data visualisation and analysis capabilities, and convenient job/batch management. View our 2020 Quantemol-VT brochure.

I have enjoyed using the Quantemol Virtual Tool (QVT) as a user-friendly front end to the Hybrid Plasma Equipment Model (HPEM) of Professor Mark Kushner. It is easy to define geometries to be modelled by the software. All of the features of the HPEM are available and the settings for these features are integrated into one user interface. After the definition of the geometry of a plasma reactor, the workflow includes setting the input parameters to the system, such as those necessary for the coupling of electromagnetic energy into the reactor,  as well as initial gas compositions in the chamber, gas flow rates and data for chemical reactions occurring in the plasma. Finally, a large range of output plasma parameters such as concentrations, fluxes, and temperatures of species can be displayed over the computation domain.”

Applications of Q-VT include:

  • Tool design and development
  • Modeling of discharge and wafer-level chemistry kinetics
  • Model etch/deposition uniformity
  • Examine tilting effects (when used with additional feature scale profile model, specifically compatible with Synopsys software)
  • Large wafer size simulation (12 inches and more)

What Q-VT can model:

  • Plasma tool geometry alterations
  • Advanced volume and surface chemistries
  • Variation of key plasma state variables with process parameter changes
  • Ion flux on wafer level: ion energy/ angular distribution functions, and fluxes of all species along the wafer
  • Non-Maxwellian electron dynamics
  • Complex electromagnetic plasma interactions (current coils, permanent magnets, multi-frequency power supply, plasma circuit interactions)

Benefits of Q-VT
