Abstract:
A phase change memory and a fabrication method are provided. The fabrication method includes: providing a substrate; forming a heating layer on the substrate; forming a phase change layer on and in contact with one sidewall surface of the heating layer. The phase change memory includes: a substrate; a heating layer on the substrate; and a phase change layer on and in contact with one sidewall surface of the heating layer.

Claim (Index 4):
The method according to  claim 3 , wherein removing the portion of the initial phase change layer from the other sidewall surface of the heating layer comprises:\n forming a patterned layer on the initial phase change layer, wherein:\n the pattern layer exposes the portion of the initial phase change layer on the other sidewall surface of the heating layer, and the pattern layer and the heating layer are partially overlapped when being projected on the substrate; and \n using the patterned layer as a mask to etch the initial phase change layer to form the phase change layer.
