Abstract
An anti-fuse element that includes a capacitance unit having an insulation layer and at least a pair of electrode layers formed on upper and lower surfaces of the insulation layer. The capacitance unit has a protection function against electrostatic discharge. Because the capacitance unit has a protection function against electrostatic discharge, an anti-fuse element can be provided which is less likely to cause insulation breakdown due to electrostatic discharge at the time of, for example, mounting a component.
Claims16
An anti-fuse element comprising:
- a capacitance unit including an insulation layer and at least a pair of electrode layers on opposed first and second surfaces of the insulation layer, wherein
- the capacitance unit has a capacitance of 1 nF to 100 nF,
- the capacitance unit is configured to have a protection function against electrostatic discharge, and
- during the application of a voltage not less than a breakdown voltage of the insulation layer, at least the pair of electrode layers are melted, and at least the pair of electrode layers are electrically connected by welding to each other.
