    Abstract: Interconnect structures possessing an organosilicate glass interlayer dielectric material with minimal stoichiometeric modification and optionally an intact organic adhesion promoter for use in semiconductor devices are provided herein. The interconnect structure is capable of delivering improved device performance, functionality and reliability owing to the reduced effective dielectric constant of the stack compared with that of those conventionally employed because of the use of a sacrificial polymeric material deposited onto the dielectric and optional organic adhesion promoter during the barrier open step done prior to ashing the patterning material. This sacrificial film protects the dielectric and optional organic adhesion promoter from modification/consumption during the subsequent ashing step during which the polymeric film is removed.

    Abstract: Interconnect structures possessing an organosilicate glass based material for 90 nm and beyond BEOL technologies in which a multilayer hardmask using a line-first approach are described. The interconnect structure of the invention achieves respective improved device/interconnect performance and affords a substantial dual damascene process window owing to the non-exposure of the OSG material to resist removal plasmas and because of the alternating inorganic/organic multilayer hardmask stack. The latter feature implies that for every inorganic layer that is being etched during a specific etch step, the corresponding pattern transfer layer in the field is organic and vice-versa.

    Abstract: A high ion energy and high pressure O2/CO-based plasma for ashing field photoresist material subsequent to via-level damascene processing. The optimized plasma ashing process is performed at greater than approximately 300 mT pressure and ion energy greater than approximately 500 W conditions with an oxygen partial pressure of greater than approximately 85%. The rapid ash rate of the high pressure/high ion energy process and minimal dissociation conditions (no “source” power is applied) allow minimal interaction between the interlevel dielectric and ash chemistry to achieve minimal overall sidewall modification of less than approximately 5 nm.

    Abstract: Interconnect structures possessing a non-porous (dense) low-k organosilicate glass (OSG) film utilizing a porous low-k OSG film as an etch stop layer or a porous low-k OSG film using a non-porous OSG film as a hardmask for use in semiconductor devices are provided herein. The novel interconnect structures are capable of delivering improved device performance, functionality and reliability owing to the reduced effective dielectric constant of the stack compared with that of those conventionally employed and also because of the relatively uniform line heights made feasible by these unique and seemingly counterintuitive features. The present invention also provides a fluorocarbon-based dual damascene etch process that achieves selective etching of a dense low-k OSG films relative to that of a porous low-k OSG film owing to the tunability of the gas-phase fluorine:carbon ratio (gas dissociation) and ion current below a critical threshold and given the larger carbon content of the porous film relative to that of the dense film.
