Abstract:
Two phase-change memory cells are formed from a first conductive via, a second conductive and a central conductive via positioned between the first and second conductive vias where a layer of phase-change material is electrically connected to the first and second conductive vias by corresponding resistive elements and insulated from the central conductive via by an insulating layer. The conductive vias each include a lower portion made of a first metal (such as tungsten) and an upper portion made of a second metal (such as copper). Drains of two transistors are coupled to the first and second conductive vias while sources of those two transistors are coupled to the central conductive via.

Claim (Index 5):
A method of manufacturing a phase-change memory, comprising:\n forming a first dielectric layer over a semiconductor substrate including a source region and a drain region of a memory transistor; forming a first opening extending through the first dielectric layer to expose the source region; forming a second opening extending through the first dielectric layer to expose the drain region; depositing a first metal material to completely fill both the first and second openings; removing a top portion of the first metal material from both the first and second openings to produce corresponding third and fourth openings; depositing a second metal material different from the first metal material to completely fill both the third and fourth and second openings; providing a resistive component over and in contact with the second metal material in the third opening; providing a phase-change material over and in contact with the resistive component; forming a first electrical connection to the phase-change material; and forming a second electrical connection to the second metal material in the fourth opening.
