  We report on hole compact double quantum dots fabricated using conventional
CMOS technology. We provide evidence of Pauli spin blockade in the few hole
regime which is relevant to spin qubit implementations.
  A current dip is observed around zero magnetic field, in agreement with the
expected behavior for the case of strong spin-orbit. We deduce an intradot spin
relaxation rate $\approx$120\,kHz for the first holes, an important step
towards a robust hole spin-orbit qubit.
