Sputter System#

API of the sputter system class.

class pysimtra.sputter_system.SputterSystem(chamber, magnetrons, dummy_objects, output_path)#
Parameters:

  • chamber (Chamber) – chamber object

  • magnetrons (list[Magnetron]) – either a single magnetron object or a list of magnetrons

  • dummy_objects (list[DummyObject]) – dummy object or list of dummy objects

  • output_path (Path) – path pointing to a directory at which the simulation results will be stored

classmethod single_from_file(path)#

Creates a sputter system with a single magnetron from a single “.sin” file.

Parameters:

path (str | Path) – path to the “.sin” file

Returns:

classmethod multiple_from_files(chamber_path, magnetron_paths, object_paths, output_path)#

Creates a sputter system with multiple magnetrons from separate “.sin”, “.smo” and/or “.sdo” files.

Parameters:

  • chamber_path (str | Path) – Path to a “.sin” file from which the chamber object will be generated

  • magnetron_paths (list[str | Path]) – Paths to the “.smo” or “.sin” files which define the magnetrons

  • object_paths (list[str | Path]) – Paths to the “.sdo” files which define the dummy objects

  • output_path (str | Path) – output path for the simulation results

simulate(magnetrons=None, n_sim=1)#

Performs a simulation of the sputter system by storing the components temporarily as “.sin” files and calling the command line version of SIMTRA. Afterward, the results directory is analyzed and the particle distributions of all those objects are returned which have the “save averaged data” attribute.

Parameters:

  • magnetrons (list[str] | None) – list of magnetron names to simulate. If not given, the deposition from all magnetrons are simulated

  • n_sim (int) – number of simulations of each magnetron. If n > 1, seed numbers are randomly generated and all simulation results will be combined for each magnetron

Returns:

either a single SimtraOutput object or a list of SimtraOutput objects for every simulated magnetron containing the simulation results

Return type:

SimtraOutput | list[SimtraOutput]

to_sin(path, mag_name=None)#

Saves the sputter system with a given magnetron as a single “.sin” file. In case multiple magnetrons were defined inside the class, the other ones are added to the file as dummy objects.

Parameters:

  • path (str | Path) – path including a filename and the “.sin” suffix

  • mag_name (str) – name of the magnetron to save, for a single magnetron system, this parameter has no effect
