Abstract:
A microelectronic method for etching a layer containing silicon nitride is provided, including the following successive steps: modifying the layer containing silicon nitride (SiN) so as to form at least one modified zone, the modifying including at least one implantation of ions made from hydrogen (H) in the layer containing SiN; and removing the at least one modified zone, the removing of the at least one modified zone including at least one step of etching of the at least one modified zone using a chemistry including at least: at least one compound chosen from the fluorocarbon compounds (C x F z ) and the hydrofluorocarbon compounds (C x H y F z ), and at least one compound chosen from Si w Cl(2 w +2) and Si w F(2 w +2).

Claim (Index 21):
The method according to  claim 19 , wherein the layer containing SiN is on top of a layer made from a material chosen from:\n a semiconductor material, preferably chosen from silicon (Si), germanium Ge), and an alloy of silicon and of germanium (SiGe), and an oxide of silicon (SiOx).
