some process tape out document note the bias of process. it seems that it is the difference between draw and mask , is it right ?
But why some process have no bias value?
Does it represent the drawing size means the real mask value ?
yeah, it's the difference between drawn and mask. i belive all experience process bias that's why we use device matching.
what i actually mean is why the process document give us the exact size after bias instead of the larger size to let us draw the enlarged size ?
it seems that we will confuse the minumum size to mis-understand the performance evaluation.
