Abstract:
Method for manufacturing an integrated circuit (101; 102; 1) formed on a semiconductor substrate (201; 2) comprising the steps of: - forming at least one shielding structure (60; 61; 6A, 6B) on said semiconductor substrate (201; 2), - forming a protective layer (100, 190; 19, 11') at least on portions of the semiconductor substrate (201; 2) that surround said shielding structure (60; 6A, 6B), - carrying out a ionic implantation step with a tilt angle with respect to a normal to a plane defined by said semiconductor substrate (201; 2) so that said at least one shielding structure (60; 61; 6A, 6B) shields first portions (200; 202; 20, 11A) of the protective layer (100, 190; 19, 11'), - removing second portions (210; 211; 21, 11B) of the protective layer (100, 190; 19, 11') that have been subjected to the ionic implant.
