Hi, I am new to device modelling. I am using TCAD sentaurus tool. when i am simulating the device in SDE in SWB, it is working properly. But when iam simulating in SDEVICE i am getting an error i.e Adding Interfaces and contacts....tried to use non existing contact Source..I add all material and material interface model parameters in .par file.
Please help me

Hi,

Thank you for your reply. the error: The child process with PID "8973" eisits with the code '1'.
gjob exits with status 1.

Error:Tried to use non existing contact 'Source'.

I don't know why this error is coming. please help me why it will arise and how to resolve this issue.
