ABSTRACT:
The conductor 15 to be connected to the doped region 12 of the substrate 11 has an edge 15a at which the laser beam 20 is aimed, regulated such as to definitively create a zone of low electrical resistance 19 in the dielectric layer 13 that separates the conductor from the doped region. The invention is particularly applicable to programming by laser of read only memories and defective integrated circuits with a view to correcting them.
