Abstract
A semiconductor device includes an element region having a gate switching element, and a temperature sensing region having a temperature sensing diode. The gate switching element in the element region includes gate trenches, gate electrodes and an interlayer insulating layer covering an upper surface of each of the gate electrodes in the gate trenches. The temperature sensing diode in the temperature sensing region includes an anode region, a cathode region, first dummy trenches provided in the anode region, a first insulating layer provided in each of the first dummy trenches, second dummy trenches provided in the cathode region, and a second insulating layer provided in each of the second dummy trenches.
