Video Tutorial of Visual TCAD
In this tutorial, you will learn
- to build the structure of a P-N junction diode in the following steps:
- Draw the outline of the device
- Define material regions
- Place doping profiles
- Generate the mesh grid
- to simulate the I-V curve of the diode, and analyze the result in the following steps:
- Load the device structure
- Setup the voltage sources attached to each electrode
- Submit the simulation job
- Plot the simulated I-V curve
- Visualize the electron concentration in the device
- Plot the electron concentration along a cut-line
- to do device-circuit mixed-mode simulation in the following steps:
- Assign a circuit symbol to the device
- Map the device electrodes to the circuit-level terminals
- Draw the circuit schematics, and place a device model in the circuit
- Submit the simulation job, and plot the simulated voltage waveform

WebTCAD
WebTCAD is the web version of Cogenda's VisualTCAD, a powerful tool of TCAD process and device simulation. It's mainly designed for teaching purpose, aimed at demonstrating/simulating industry-standard semiconductor fabricating and working process. The intuitive graphic UI, step-by-step workflow, and fully featured post process ability make it much easier for university teachers and students to use.

CMOS Logic Gates
Want to simulate small logic circuit cells in 3D? Genius allows you to simulate a complete cell in a single TCAD model.
Or if you want to simulate it the traditional way, you can still perform a mixed-mode circuit and device simulation using SPICE.
