DevEdit

Structure and Mesh Editor

DevEdit can be used to either create a device from scratch or to remesh or edit an existing device. DevEdit creates standard Silvaco structures that are easily integrated into Silvaco 2D or 3D simulators and other support tools.

Key Features

Region Editing

• Specify regions of arbitrary materials and polygonal shapes
• Modify existing regions, altering material, shape, or base impurity
• Add new regions to existing devices, automatically etching away parts of regions or leaving the regions unchanged
• Define electrode location, name, and work function

Doping Editing

• Add analytical doping profiles such as Gaussian or complementary error function
• Combine multiple 2D devices to create new 2D doping profiles
• Import 1D doping profiles
• Combine 1D doping profiles with analytical doping profiles to create quick yet realistic doping concentrations
  

Meshing 2D

• Creates high quality triangle meshes with minimal obtuse triangles
• Maintain mesh details using refinement criteria while reducing the elements in areas that do not have useful detail
• Allows user control over detail retention through multiple criteria, include material type, quality change, location, or relative location

Meshing 3D:

• Creates high quality prisms or tetrahedra based on the same algorithm used for 2D meshes
• Allows understandable 1 plane refinement criteria to be expanded to the third dimension using a simple but flexible plane creation algorithm

Interface

• Reads in 2D structures created by process and device simulators like ATHENA and ATLAS
• Reads in 1D Doping profiles from ATHENA
• Writes out 2D structures for process and device simulators like ATHENA and ATLAS
• Writes out 3D structures for device simulators like ATLAS-3D and VictoryDevice
