Abstract: A method of manufacturing a contact on a semiconductor region includes a step of forming a stack of layers on lateral walls and at a bottom of an orifice (aligned with the semiconductor region) crossing a dielectric region along a longitudinal direction. The step of forming step is carried out from a first surface of the dielectric region and includes forming a polysilicon layer and a layer of a first metal in contact with the polysilicon layer. The first metal is preferably a metal selected from the group of transition metals and is well suited to forming with the polysilicon layer a metal silicide. The method further includes a step of performing thermal anneal causing a reaction between the first metal and the polysilicon layer to produce a layer of metal silicide. At least a portion of that layer of metal silicide extends in the longitudinal direction of the orifice.
