dummy transistors
is it only for even number of fingers or should apply everytime we use multifinger? Help please....[/quote]
The dummy structure is not only for even fingers, but also for odd fingers or you think you should use the dummy for immunity orther fabrication influence:diffusion imp and so on.
I think you can get two mirrors. and take the two mirrors under the sun. You should see the different between the mirrors and the sides of the mirrors.
If you want to get the same shallow, i think you can take more mirrors, maybe 4. and take the four mirrors under the sun, you can get the same shallow. The trasnsitor is the same while fabrication.
Or, you can info for a process engineer. The above is my opion.
I think the dummy is not only use for immunity fabrication, maybe some other surroundings we can use.
And the more fundamental about dummy, you can refer to <<The Art of Ananlog Layout>> or other books.
Best wishes for you
