摘要： A bonding pad having an anti-pad peeling-off structure is disclosed. In a method of forming the bonding pad, after a metal pad layer is formed, a slit is formed in the metal pad layer. A protecting layer is formed on the metal pad layer. The protecting layer is partially removed to expose the metal pad such that a portion of the protecting layer remains in the slits to be connected to the main protecting layer. The protecting layer formed in the slit is connected to the protecting layer such that the residual protecting layer pattern buffer when physical impacts are generated, to prevent peeling-off of the metal pad layer.

摘要： a nonvolatile memory device Includes an active region defined in a semiconductor substrate and a control gate electrode crossing over the active region. A gate insulating layer is interposed between the control gate electrode and the active reigon. A floating gate is formed in the active region to penetrate the control gate electrode and extend to a predetermined depth into the semiconductor substrate. A tunnel insulating layer is successively interposed between the control gate electrode and the floating gate, and between the semiconductor substrate and the floating gate. The floating gate may be formed after a trench is formed by sequentially etching a control gate conductive layer and the semiconductor substrate, and a tunnel insulating layer is formed on the trench and sidewalls of the control gate conductive layer. The floating gate is formed in the trench to extend into a predetermined depth into the semiconductor substrate.
