  We show how to measure and manipulate a single spin in a CMOS device
fabricated in a pre-industrial 300 mm CMOS foundry. The device can be used as a
spin quantum bit working at very low temperature. The spin manipulation is done
by a microwave electric field applied directly on a gate. The presented results
are a proof-of-principle demonstration of the possibility to define qubits by
means of conventional industrial fabrication processes.
