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.
