Abstract:
An interconnect structure comprising:a first planar network of electrical conductors formed in a first deposition process; a second planar network of electrical conductors formed in a second deposition process, and separated from the first planar network by a separation region; and a single interlevel dielectric material disposed within the separation region and extending into a portion of the first planar network, without other intervening insulating materials between the first and second planar networks, such that the interlevel dielectric material has a planarized surface that interfaces the second planar network of electrical conductors, the interlevel dielectric material comprising a polysiloxane network consisting essentially of silicon, oxygen, carbon and hydrogen and incorporating carbon-silicon bonding and having a dielectric constant of less than about 3.3.
