Machines of earlier years had something called microprogramming
below the machine language level.

After the advent of RISC machines (ie for the last 20 years or so)
this is not available to a 'normal' user.
[Where by 'normal' user I mean someone who is not an employee
of Intel for example].
Classic book for this is Tanenbaum's Structured computer organization.

Then below this is a bunch of layers (very remote from programming) which electronics folks deal with going upto the 
solid-state physics of silicon
