MULTIPOLE POWER CHIP (S) MONOLITHICALLY INTEGRATING ASYMMETRICAL CUTTING CELLS AND MULTI-PHASE POWER MODULE (S) USING ONE OR MORE OF SAID MULTIPOLE CHIPS

摘要

A multipole power chip has two switching cells (1221, 1222), vertically integrated and laterally distributed in a semiconductor substrate (112). Each switching cell (1221, 1222) is double-compartmentalized by a non-crossing insulating enclosure wall (1241, 1242) in a first volume (1341, 1342) and a second volume (1361, 1362) comprising respectively a diode ( 1301, 1302) and a controlled electronic switch (1321, 1322) forming a cutting structure. Each switching cell (1221, 1222) comprises at the level of the first upper face (114) an electrical polarity terminal (1381, 1382) and a ground terminal (1401, 1402). Each switching cell (1221, 1222) has a one-piece midpoint terminal (1411, 1412) disposed below the first and second volumes and at or below and set back from the second lower face (116 ) of the substrate (112).
