Abstract:
Example embodiments are directed to a stack-type image sensor including resistance change elements. The stack-type image sensor includes at least two light-sensing layers that detect different color light stacked on different layers. The stack-type image sensor may not require a size of a unit pixel that detects a light color to be less than 1 μm in order to generate a high resolution color image. As such, resolution saturation may be avoided.
Abstract:
A stack-type capacitor includes a lower electrode, a dielectric layer formed on the lower electrode, and an upper electrode formed on the dielectric layer, wherein the lower electrode includes a first metal layer having a cylindrical shape and a second metal layer filled in the first metal layer. In the capacitor, an amount of oxygen included in the lower electrode is decreased to suppress oxidation of a TiN layer. Thus, a stable stack-type capacitor may be formed, which increases greatly the performance of highly integrated DRAMs.
