Silvaco IC simulation with Athena Atlas

Click For Summary
SUMMARY

The discussion centers on issues encountered while using Silvaco Athena and Atlas for IC simulations, particularly in MOS structures and solar cell simulations. Users reported discrepancies in threshold voltage (Vth) when altering gate lengths, with a noted drop from 1.8V to 1.6V as gate length decreased from 0.6um to 0.55um. Additionally, errors related to file access, such as "Solarx01.spec," and challenges in incorporating external files for spectral absorption coefficients were highlighted. Users also sought guidance on applying "Non local band to band" tunneling in Silvaco Atlas for junctionless devices and optimizing efficiency in GaAsN alloy solar cells.

PREREQUISITES
  • Familiarity with Silvaco Athena and Atlas simulation software
  • Understanding of MOS structure parameters and their impact on threshold voltage
  • Knowledge of solar cell physics, particularly regarding GaAsN alloys
  • Experience with file management and external data integration in simulation tools
NEXT STEPS
  • Investigate Silvaco Atlas documentation on MOS structure simulations
  • Learn how to troubleshoot file access errors in Silvaco software
  • Research methods for integrating external text files in Silvaco Atlas
  • Explore techniques for implementing "Non local band to band" tunneling in Silvaco simulations
USEFUL FOR

Engineers and researchers working with Silvaco Athena and Atlas, particularly those involved in IC design, solar cell development, and semiconductor physics.

I have a question about silvaco athena && atlas simulation, MOS structure, when I gate length is 0.6um, get Vth is 1.8V, but I only change gate length to 0.55um, get Vth is 1.6V, it's a error data I know, but I do not know why, what wrong with the program, how can I change it. would you please help about it. Very thanks!

Hi, i have problem with Silvaco please. when i simulate an PIN solar cell by atlas, an error message appear and say The atlas Silvaco could not open the file called "Solarx01.spec", i know no where is the problem realy! another question: how we can include an external files (.txt) who contains for example the spectral absorption coeficient or the reflexion in the atlas. Thanks
 
How to apply "Non local band to band" tunneling in Silvaco Atlas for a junctionless device?
 
hi ,i need help
i simulate a program in silvaco about solar cell with GaAsN alloy and i have a problem
in my program i need that the efficiency when i increase the numbre of the quantum well it should increase to but in my case it decreases
if you have any idea please help me
