Claim 7:
8. The method according to claim 1, wherein forming the protective layer further comprises:
oxidizing, in a differentiated manner, the front face of the substrate and the sidewalls of the gate, such that a thickness ef of oxide formed at the sidewalls of the gate is strictly less than a thickness es of oxide formed at the front face of the substrate, such that ef≤k.es where k≤0.8 and preferably k≤0.5, and
removing the oxide formed at the sidewalls of the gate, said removal being configured to retain at least some of the oxide formed at the front face of the substrate so as to form the protective layer.
