Abstract: A method of forming a memory device includes the following operations. A first conductive plug is formed within a first dielectric layer over a substrate. A treating process is performed to transform a portion of the first conductive plug into a buffer layer, and the buffer layer caps the remaining portion of the first conductive plug. A phase change layer and a top electrode are sequentially formed over the buffer layer. A second dielectric layer is formed to encapsulate the top electrode and the underlying phase change layer. A second conductive plug is formed within the second dielectric layer and in physical contact with the top electrode. A filamentary bottom electrode is formed within the buffer layer.

Abstract: Nanowire devices and fin devices are formed in a first region and a second region of a substrate. To form the devices, alternating layers of a first material and a second material are formed, inner spacers are formed adjacent to the layers of the first material, and then the layers of the first material are removed to form nanowires without removing the layers of the first material within the second region. Gate structures of gate dielectrics and gate electrodes are formed within the first region and the second region in order to form the nanowire devices in the first region and the fin devices in the second region.
