Abstract:
A device includes a substrate, an insulating member disposed on a surface of the substrate, a gate, and a cathode. The insulating member has an upper surface apart from the surface of the substrate, and a side surface rising from the surface of the substrate between the upper surface and the surface of the substrate. The gate is disposed on the upper surface of the insulating member. The cathode is disposed on the side surface of the insulating member and has a portion opposing the gate. The side surface of the insulating member on which the cathode is disposed has a protruding portion protruding from an imaginary line connecting a position where the portion opposing the gate lies and a position where the insulating member rises from the surface of the substrate.
