Patent ID: 7138900

Claim:
A resetable over-current protection device, comprising: a resistance variable material having a top surface, a bottom surface, a left end face, and a right end face; a top laminar electrode disposed on the top surface, the top laminar electrode having a top trench for exposing a part of the material; a bottom laminar electrode disposed on the bottom surface; a top insulation layer covering a part of the top laminar electrode and the top trench; a bottom insulation layer covering a part of the bottom laminar electrode; a first left connection layer, covering a part of the left end face of the material, and the top laminar electrode and bottom laminar electrode proximate to the left end face, for electrically connecting the top laminar electrode and the bottom laminar electrode; a first right connection, covering the top laminar electrode proximate to the right end face; a second left connection layer, covering the first left connection layer to serve as a first contact point; and a second right connection, covering the first right connection to serve as a second contact point.
