2 Benefits of Q-VT An experimentally validated simulation system focused on modelling plasma tools User-friendly interface Sets of validated cross-sections are provided with the licence What does Q-VT do? Quantemol-Virtual Tool 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 the renowned plasma physicist Professor Mark Kushner for simulating non-equilibrium low pressure plasma processes. Q-VT includes an intuitive user interface, data visualisation and analysis capabilities, and convenient job/batch management. Plasma chemistry sets can be directly imported from QDB Examples of commonly used ICPs and CCPs are included Easy-to-use drawing tool for chamber design and modification: a tool simulation set-up service can be provided The ability to model complex plasma phenomena with additional modules (dust/radiation transport, ion kinetics, external circuits, etc.) Multi jobs run management system for managing large numbers of simulations Advanced reactor scale visualisation of scalar and vector plasma properties Possibility to import experimental results Ability to easily distribute and manage jobs over a cluster NEW: Import chemistries from QDB Contact us: Phone: info@quantemol.com Quantemol Ltd 320 Angel City Road London EC1V 2NZ Calculate Arrhenius parameters from user-provided cross sections Three rf-voltages on one electrode, initial GUI for surface module Updated species list Add user reaction database, so no need to add the same reactions over and over manually (Optional) API to add your cross sections to HPEM library (currently you can only use hard coded cross sections

3 What can Q-VT 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 and energy neutral 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, electrodynamic effects on CCPs) Pulsed plasma discharges Fig.1 The simulation consists of a core simulation module, the HPEM, which can be extended with additional add-on modules to incorporate the physics of interest in a given plasma process. Applications of Q-VT Tool design and development Modelling of discharge and wafer level chemistry kinetics Modelling etch/deposition uniformity Examining tilting effects (when used with an additional scale profile model feature, specifically compatible with Synopsys TCAD software) Large wafer size simulation (12 inches and more)

4 In Quantemol-VT, tool settings can be easily modified through the intuitive design viewer. The simulation projects are organised and structured with a workbook management system. With the help of a graphical meshing tool, the chamber design can be drawn with materials of your choice in 2D (planar) and 2.5D (axisymmetric cylindrical geometry). Results can be plotted and analysed within Q-VT or exported as data files. Outputs from Q-VT include: 2D distributions of species densities, temperatures, fluxes, fields and power depositions, surface fluxes, timeresolved kinetics, spatially resolved EEDFs, and ion/neutral energy/angle distributions.
