    摘要: Disclosed herein is a method of fabricating a semiconductor device having a metal fuse. The method includes forming a plate electrode on a semiconductor substrate, forming an interlayer insulating layer on the plate electrode, forming a barrier metal layer containing either silicon or aluminum, a first metal layer and an antireflection layer containing either silicon or aluminum sequentially from bottom to top on the interlayer insulating layer. The method also includes patterning the antireflection layer, the first metal layer, and the barrier metal layer to form a first metal interconnection. The method also includes forming a fuse with the same material and structure as those of the first metal interconnection while forming the first metal interconnection. The method further includes forming an inter-metal dielectric layer on the first metal interconnection and the fuse, forming a second metal interconnection on the inter-metal dielectric layer, forming a passivation layer on the second metal interconnection, and forming a fuse box in the passivation layer.

    摘要: The manufacturing of a phase change memory device that includes a switching device, a bottom electrode contact in contact with the switching device and a porous spacer formed on the bottom electrode contact. The formed bottom electrode contact exposes a switching device on a semiconductor substrate which the switching device is formed in, forming an insulating layer on a resultant structure of the semiconductor substrate including the bottom electrode contact by using an insulating compound having materials with different atomic sizes, and forming an insulating spacer within the bottom electrode contact hole by selectively etching the insulating layer.

    摘要: A phase change memory device is presented that has a lower electrode contact that has a gradient resistance profile ranging from a lower resistive lower end to a higher resistive upper end. The phase change memory device includes a semiconductor substrate, a lower electrode contact, and a phase change pattern. The semiconductor substrate has a switching device. The lower electrode contact is formed on the switching device and has a specific resistance which gradually increases from a lower part to an upper part of the lower electrode contact. The phase change pattern layer is formed on the lower electrode contact.
