The paper thus acted as the dielectric between the components of each transistor, as well as being the substrate for the circuit, in the same way that the base of a silicon chip acts both as substrate and as dielectric.

The investment will allow the base to make the latest system-on-chip designs in which various technologies are integrated onto the same circuit, helping minimise manufacturing costs.
