Interconnect structures with engineered dielectrics with nanocolumnar porosity |
摘要 |
A method for forming an interconnect structure with nanocolumnar intermetal dielectric is described involving the construction of an interconnect structure using a solid dielectric, and introducing a regular array of vertically aligned nanoscale pores through stencil formation and etching to form a hole array and subsequently pinching off the tops of the hole array with a cap dielectric. Variations of the method and means to construct a multilevel nanocolumnar interconnect structure are also described.
