Claim 7:
8. A three-phase inverter power chip, comprising:
a substrate;
a channel layer provided on one side surface of the substrate;
a plurality of active areas, each of the plurality of active areas comprising a potential energy barrier layer and a chip device layer sequentially arranged on the channel layer, wherein: the chip device layer comprises source electrodes, drain electrodes, gate electrodes and a metal interconnection layer; the metal interconnection layer has a source electrode interconnection metal part corresponding to each of the source electrodes, a drain electrode interconnection metal part corresponding to each of the drain electrodes, and a gate electrode interconnection metal part corresponding to each of the gate electrodes; the plurality of active areas form three active area pairs arranged along a first direction; each of the three active area pairs comprises two active areas; in each of the active area pairs, one active area is configured to form a high-side transistor therein and is named as a first active area, and the other active area is configured to form a low-side transistor therein and is named as a second active area;
an isolation area, arranged between the active areas to separate the active areas from each other, and extending from the channel layer towards a side away from the substrate, wherein: the isolation area is provided with a first bond pad, second bond pads corresponding one-to-one with the three active area pairs, third bond pads corresponding one-to-one with the three active area pairs, and fourth bond pads corresponding one-to-one with the active areas; the drain electrodes in the first active area are electrically connected to the first bond pad by respective drain electrode interconnection metal parts thereof; the source electrodes in the first active area are electrically connected to corresponding the second bond pads by respective source electrode interconnection metal parts thereof; the drain electrodes in the second active area are electrically connected to corresponding the second bond pads by respective drain electrode interconnection metal parts thereof; the source electrodes in the second active area are electrically connected to corresponding the third bond pads by respective source electrode interconnection metal parts thereof; and the gate electrodes in the active areas are electrically connected to corresponding the fourth bond pads by respective gate electrode interconnection metal parts thereof.
