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

摘要

A multi-power chip includes two vertically integrated switching cells (1221, 1222) laterally distributed in a semiconductor substrate (112). Each switching cell (1221, 1222) is double-partitioned by a non-through insulating wall (1241, 1242) in a first volume (1341, 1342) and a second volume (1361, 1362) respectively having a diode ( 1301, 1302) and a controlled electronic switch (1321, 1322) forming a cutting structure. Each switching cell (1221, 1222) has at the first top face (114) an electrical polarity terminal (1381, 1382) and a ground terminal (1401, 1402). Each switching cell (1221, 1222) has an integral mid-point terminal (1411, 1412) disposed below the first and second volumes and at or below and recessed from the second lower face (116). ) of the substrate (112).
