Single digit nanometers seems to be the limit we currently have both for photo lithography and magnetic storage. Considering the diameter of an atom is just an order of magnitude less (0.1nm to 0.5nm), I feel we are really close to the physical limit. Scaling down feature size will become impossible really soon.
