At what bases we fix the specification values in device modeling of TCAD simulation tool. how do you know these specification values (i.e., doping concentration values, channel length and gate ,source and drain length ) are correct.
Validation is based on previous work done or theoretical outcome.
We need to validate our model with values of previous work done and analyse the outcome based on previous work
Dear Dharmireddy Ajaykumar:
In device modeling within TCAD (Technology Computer-Aided Design) simulation tools, specification values are critical parameters that define the physical characteristics and behavior of semiconductor devices. These values are based on a combination of device physics, material properties, and design considerations. Here's how some of these specification values are determined and fixed:
To ensure that the specification values are correct, it's essential to perform model calibration, validate against experimental data, and consider the device's intended application and performance requirements. Additionally, semiconductor device modeling often involves iterative optimization to achieve the desired results, and simulation tools are valuable for this purpose. Collaboration between process engineers, device designers, and TCAD simulation experts is crucial in accurately defining and refining these values.
