摘要： A chemical mechanical polishing (CMP) step is used to remove excess conductive material (e.g., Cu) overlying a low-k or ultralow-k interlevel dielectric layer (ILD) layer having trenches filled with conductive material, for a damascene interconnect structure. A reactive ion etch (RIE) or a Gas Cluster Ion Beam (GCIB) process is used to remove a portion of a liner which is atop a hard mask. A wet etch step is used to remove an oxide portion of the hard mask overlying the ILD, followed by a final touch-up Cu CMP (CMP) step which chops the protruding Cu patterns off and lands on the SiCOH hard mask. In this manner, processes used to remove excess conductive material substantially do not affect the portion of the hard mask overlying the interlevel dielectric layer.

摘要： In a multilevel microelectronic integrated circuit, air comprises permanent line level dielectric and ultra low-K materials are via level dielectric. The air is supplied to line level subsequent to removal of sacrificial material by clean thermal decomposition and assisted diffusion of byproducts through porosities in the IC structure. Optionally, air is also included within porosities in the via level dielectric. By incorporating air to the extent produced in the invention, intralevel and interlevel dielectric values are minimized.

摘要： A hardmask layer in the back end of an integrated circuit is formed from TaN having a composition of less than 50% Ta and a resistivity greater than 400 μOhm-cm, so that it is substantially transparent in the visible and permits visual alignment of upper and lower alignment marks through the hardmask and intervening layer(s) of ILD. A preferred method of formation of the hardmask is by sputter deposition of Ta in an ambient containing N2 and a flow rate such that (N2 flow)/(N2+carrier flow)>0.5.

摘要： A metal hardmask for use with a Dual Damascene process used in the manufacturing of semiconductor devices. The metal hardmask has advantageous translucent characteristics to facilitate alignment between levels while fabricating a semiconductor device and avoids the formation of metal oxide residue deposits. The metal hardmask comprises a first or primary layer of TiN (titanium nitride) and a second or capping layer of TaN (tantalum nitride).
