Every software package contains a full set of examples suitable for that version and are installed with the software. If you see examples here that are not in your installation you should consider updating to a later version of the software. These examples can be used by beginners and advanced users for product evaluation, teaching purposes, and self-training.

Required Modules

Victory Process

• 3D Implantation and Diffusion

Victory Mesh

• 3D Meshing

Victory Device

• 3D Device Simulator
• 3D Single Event Effects

This examples demonstrates SEU simulation in a diode structure in three dimensions initiated by multiple tracks. Time dependence of the carrier generation is also included in the specification of the second particle track. The input file consists of the following parts:

Construction of the 3D device in Victory Process

Transfer of the Victory Process structure to Victory Mesh for remeshing the structure

Transfer of the Victory Mesh structure to Victory Device for device modelling

Physical models specification

SEU parameter specification

Simulation of the effects of SEU

The diode structure under consideration is the same as in the previous example and is constructed with the Victory Process. The structure is then passed to Victory Mesh for remeshing and then to Victory Device for electrical calculations. The same set of physical models is applied.

singleeventupset statements are now used to specify entry and exit points, radius and density of generated electron-hole pairs due to two alpha particle tracks. Different from the first track where the generation rate is position dependent, only the second track includes position and time dependent generation. Parameters tc and t0 in the second statement specify the characteristic time of the Gaussian time dependency, and the time instant of the peak of generation.

The cathode voltage is ramped here up to 20V in the DC mode, and then the transient analysis is performed to simulate charge collection in the device.

The numerical algorithms that are used repeat those of the previous example.

The results of the simulation are saved in the log file and then displayed using Victory Visual.
