Dual damascene copper is a class of metallization materials designed to support the dual damascene patterning process, a common technology used in semiconductor wafer processes to create the circuitry between the transistors on a chip. After depositing a dielectric to create the circuitry pattern on the wafer, dual damascene copper is used to fill the trenches and create the interconnects.
As the semiconductor industry continues to shrink technology nodes, it relies on dual damascene copper to meet tight requirements to achieve finer feature sizes in the circuitry, in accordance with Moore's Law. Today's dual damascene copper material needs to:
