The die photo for the Infineon 1014 ASIC doesn't reveal too much about its functional layout -- there is a large metal layer over the circuit.
The metal layer could be acting as a ground plane or might be used RF shielding; or it may simply stop folks from looking at the die circuitry now that teardowns are getting popular.
But don't worry, we got you
uncoveredcovered. Chipworks had no problem removing the metal layer in order to expose the ASIC die.
