Abstract
A semiconductor chip includes a first electrode connected to a gate of a power device, a second electrode connected to an emitter or a source of the power device, a third electrode, and a gate protection element. The gate protection element includes a first node and a second node, and a plurality of stages of p-n junctions formed between the first node and the second node. When one of the first electrode and the second electrode is a target electrode and the other is a non-target electrode, and the first node is connected to the third electrode and the second node is connected to the target electrode. Then, the first electrode, the second electrode, the third electrode and the gate protection element are formed in the same semiconductor chip.
