Abstract: An advanced back-end-of-line (BEOL) metallization structure is disclosed. The structure includes a bilayer diffusion barrier or cap, where the first cap layer is formed of a dielectric material preferably deposited by a high density plasma chemical vapor deposition (HDP CVD) process, and the second cap layer is formed of a dielectric material preferably deposited by a plasma-enhanced chemical vapor deposition (PE CVD) process. A method for forming the BEOL metallization structure is also disclosed. The invention is particularly useful in interconnect structure comprising low-k dielectric material for the inter-layer dielectric (ILD) and copper for the conductors.

Abstract: AN ADVANCED BACK-END-OF-LINE (BEOL) METALLIZATION STRUCTURE IS DISCLOSED. THE STRUCTURE INCLUDES A BILAYER DIFFUSION BARRIER OR CAP, WHERE THE FIRST CAP LAYER (116, 123) IS FORMED OF A DIELECTRIC MATERIAL PREFERABLY DEPOSITED BY A HIGH DENSITY PLASMA CHEMICAL VAPOR DEPOSITION (HDP CVD) PROCESS, AND THE SECOND CAP LAYER (117, 124) IS FORMED OF A DIELECTRIC MATERIAL PREFERABLY DEPOSITED BY A PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITION (PE CVD) PROCESS. A METHOD FOR FORMING THE BEOL METALLIZATION STRUCTURE IS ALSO DISCLOSED. THE INVENTION IS PARTICULARLY USEFUL IN INTERCONNECT STRUCTURES COMPRISING LOW-K DIELECTRIC MATERIAL FOR THE INTER-LAYER DIELECTRIC (ILD) AND COPPER FOR THE CONDUCTORS.
