Impressive to replicate silicon semiconductor process. But wouldn't it be more feasible to develop as good enough process node, flexible, thin film semiconductor devices? Have been observing developments of plastic based transistors, inks, processes like nanoimprint lithography, Cleanroom in a STEM microscope and Chad Mirkin's Tera Print system. Can a small scale nanfab emerge using tech such as Nano-Ops http://nano-ops.net/nanoscale-printing/ ?

I imagine flexible, thin film, large panel based semiconductor SoC. It will not be just a mere microcontroller or IoT node, but a full fleged computing form factor. Think your wall as big plastic computer.
