You are correct, since chips designed at around 5-7 nm are much more likely to be hit with radiation. However, by scaling up the chip, you can be a lot more tolerant to it. Because of this, most chips are fabbed at around 28 nm. Generally, you want a mix of both things. You can harden a chip by shielding it, but that doesn't stop everything, so you add some fault tolerance.
