    摘要: A method of forming a metal or metal nitride layer interface between a copper layer and a silicon nitride layer can include providing a metal organic gas or metal/metal nitride precursor over a copper layer, forming a metal or metal nitride layer from reactions between the metal organic gas or metal/metal nitride precursor and the copper layer, and depositing a silicon nitride layer over the metal or metal nitride layer and copper layer. The metal or metal nitride layer can provide a better interface adhesion between the silicon nitride layer and the copper layer. The metal layer can improve the interface between the copper layer and the silicon nitride layer, improving electromigration reliability and, thus, integrated circuit device performance.

    摘要: A non-planar target can be configured for use in a plasma vapor deposition (PVD) process in which ions bombard the non-planar target and cause alloy atoms present in the non-planar target to be knocked loose and form an alloy film layer. The target includes a top planar section having a first alloy concentration and a side annular section having a second alloy concentration. The side annular section has ends coupled to ends of the top planar section. The first alloy concentration and the second alloy concentration are different.

    摘要: A proximity sensor is described including a capacitor formed by a first conductive element and a second conductive element. The first conductive element and the second conductive element are situated at a magnetic head, a slider that connects to the magnetic head, a reader of the magnetic head, a writer of the magnetic head, a reader shield of the magnetic head, or a writer shield of the magnetic head. A capacitance and a fringing electric field are formed by the capacitor when there is a voltage difference between the first conductive element and the second conductive element. The capacitor is situated such that the fringing electric field changes with a positioning change of a magnetic storage medium with respect to at least one of the first conductive element and the second conductive element. The capacitor is also situated such that the capacitance changes with the fringing electric field change.
