Re: Technology shrinking
Hope I have understood what u have asked.
To provide more die or sample die on a wafer, some foundry provide the shrinking service,for example: you chip is 5mm*5mm after layout a design, if the foundry provide the 0.9 shrink service, then in manufacture, the chip will be 4.5mm*4.5mm
the shrink manner is variety, some foundry reversve the channel L and channel W value,only shrink the wire spacing contact size,etc; some foundry shrink all the demension.
we can think that, if a tr shrink the W and L with the same ratio, the W/L is not changed, though its characteristics has a little change; the W and L of the resistor shrink with the same ratio, the res value will not change; the cap value will change after change, so if we know the chip will shrink before we do layout, we need to account for this.
