    Abstract: A semiconductor integrated device of the MOS type comprising a substrate (1, 2) of a first conductivity type is described. The substrate (1) comprising a plurality of active zones (300; 301) and inactive zones; the active zones (300; 301) comprise elementary MOS cells of said semiconductor device which are alternated to a plurality of separation zones (31). Each one of the elementary MOS cells comprises at least one source region (8), at least one drain region (7) and at least one gate structure (4, 5); said at least one gate structure (4, 5) comprises at least one first conductor material finger (5). The device comprises first metal stripes (50; 55) adapted for contacting said source regions (8) of the active zones (300; 301), second metal stripes (110, 11) adapted for contacting the drain regions (7) and third metal stripes (60) placed on the inactive zones and adapted for contacting said at least one conductor material finger (5) of each elementary cell by forming a contact point (Q) formed by a first prolongation of said at least one finger (5) for connecting with one of said third stripes (60); the first metal stripes (50; 55), the second metal stripes (110, 11) and the third metal stripes (60) being placed on the substrate (1, 2) of semiconductor material substantially at the same level. At least one of said third metal stripes (60) comprises at least one fourth metal stripe (20) placed on one of said separation zones (31). At least one conductor material finger (5) of each elementary cell has at least one second prolongation (51; 52) and the at least one fourth metal stripe (20) has at least one first prolongation (21, 22) adapted for being placed on said at least one second prolongation (51; 52) of said at least one material conductor finger (5) to form at least another contact point (T; H).
