I caught this today … IBM going further and further with their
molecular-scale lithography.  They are now able to write compounds
onto a substrate at sizes down to 10 nanometers.  We are getting
closer and closer to molecular manufacturing at a whole new scale.

IBM uses atomic microscope for direct writing.
IBM has unveiled a new method of direct writing (like an inkjet
printer) to substrates that harnesses an atomic force microscope (AFM)
to electronically control molecular-scale lithography.

For semiconductors, IBM’s new electronically controlled … [KurzweilAI.net Accelerating Intelligence News]
