Abstract
An electronic equipment is provided with a semiconductor device including an electrode joined to an electric conductor via a joint layer, a calculator and a controller. The semiconductor device is configured to pass current bidirectionally. The calculator is configured to calculate an imbalance EM progression index. The imbalance EM progression index is a difference between a forward current EM progression index and a reverse current EM progression index. The controller is configured to: adopt a condition to accelerate an increase rate of the reverse current EM progression index in at least a part of an excessive forward current EM period; and adopt a condition to accelerate an increase rate of the forward current EM progression index in at least a part of an excessive reverse current EM period.
