By the standards of the rest of the industry, the circuit pattern is quite crude, and the transistor is 25 times as large as those found in conventional, modern chips.

In particular, the processes by which the circuit pattern is first projected on to a chip's surface lithographically, and then etched on to it chemically, will need to be altered to take account of the fact that the surface is curved.
