Hi.

I'm designing a circuit in a 130nm technology. Minimum L=120nm, a minimum W=160nm.

For example, if a channel length of some transistor is set to 1um, what is the resolution in which I can change the length so that this change can still be produced in a given technology?

I presume the answer is not 130nm? Can I set L to 1.01um? (10nm change)?

Thanks,
Ivan
 

There will be a minimum step size or grid specified in the process documentation. Probably 0.01um, but you need to check. If so, you could have L=1um, 1.01um etc.
