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).
摘要:
An interconnect structure in the back end of the line of an integrated circuit forms contacts between successive layers by removing material in the top surface of the lower interconnect in a cone-shaped aperture, the removal process extending through the liner of the upper aperture, and depositing a second liner extending down into the cone-shaped aperture, thereby increasing the mechanical strength of the contact, which then enhance the overall reliability of the integrated circuit.

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.
