Abstract:
A phase change memory includes an L-shaped resistive element having a first part that extends between a layer of phase change material and an upper end of a conductive via and a second part that rests at least partially on the upper end of the conductive via and may further extend beyond a peripheral edge of the conductive via. The upper part of the conductive via is surrounded by an insulating material that is not likely to adversely react with the metal material of the resistive element.

Claim (Index 6):
A method for manufacturing phase change memory, comprising:\n depositing a first layer of a first insulating material on a second layer of a second insulating material; forming a conductive via traversing through the first and second layers; depositing a third layer of the first insulating material; forming a cavity in the third layer of first insulator that at least partially reveals an upper end of the conductive via; depositing a layer of a resistive material on a side wall and bottom of the cavity, wherein the first insulating material is not likely to react with the resistive material; forming a first spacer on the layer of a resistive material in the cavity; etching away the resistive material not protected by the first spacer; forming a second spacer on the first spacer; filling the cavity with fourth layer of an insulating material; and depositing a layer of phase change material on the fourth layer and in contact with an end of the layer of resistive material.
