Researchers at MIT made a breakthrough in a system which could in the future replace or rather change the manufactoring processes of processors based on lithography.
They have created molecular chains, to be precise copolymers that are capable of being arranged to form motifs. These motifs could become transistors.
Of course, one is still at light years away from being able to manufacture processors, but not so far from being able to produce simple chips, typically memories. These are indeed made up of completely repetitive patterns representing the cells of data storage. One could imagine in future that it is enough to soak plates in liquids before polymerizing them to produce memory chips whose capacity will be defined by the size of the plates and the properties of these copolymers since one can also imagine them to have 3D structures.
