POST-FABRICATION SELF-ALIGNED INITIALIZATION OF INTEGRATED DEVICES
摘要：
A phase change memory (PCM) cell that includes a first electrode contacting a first layer of material having a first chemical composition. The PCM cell also includes a second layer of material having a second chemical composition and a second electrode contacting the first layer of material or the second layer of material. The PCM cell is configured for receiving at least one electrical current pulse flowing from the first electrode to the second electrode to locally heat a region of the first layer and the second layer to cause at least one of inter-diffusion and liquid mixing of the first layer of material and the second layer of material, resulting in a self-aligned region of phase change material having a chemical composition that is a mixture of the first chemical composition and the second chemical composition.
摘要（中）：

一种相变存储器（PCM）单元，其包括接触具有第一化学成分的第一材料层的第一电极。 PCM单元还包括具有第二化学成分的第二层材料和与第一材料层或第二材料层接触的第二电极。 PCM单元被配置用于接收从第一电极流向第二电极的至少一个电流脉冲，以局部加热第一层和第二层的区域，以引起第一和第二层之间的至少一个相互扩散和液体混合 材料层和第二层材料，导致相变材料的自对准区域具有作为第一化学组成和第二化学组合物的混合物的化学组成的自对准区域。
