Amusingly, in a way, we are using microphotography (photolithography) to produce images on the scale of hundreds of atoms. Then we stack those images to achieve dense structures of data that can be read out electronically (flash chips).
Making a rom chip using this technology would be a lot like that encyclopedia britannica in a matchbox, except more around the size of a grain of dust. Of course we tend to make ram instead, where information is only encoded after the photolithography is done creating the structure.
