Silicon carbide stop layer in chemical mechanical polishing over metallization layers |
摘要 |
Silicon carbide (SiC) is used as the stop layer for the chemical-mechanical polishing used to planarize the surface of interlevel dielectrics, making the resistance of the vias more uniform. Alternatively, silicon carbonitride or silicon carboxide can be used in place of silicon carbide.
