摘要： A plasma cleaning method particularly useful for removing photoresist and oxide residue from a porous low-k dielectric with a high carbon content prior to sputter deposition. A remote plasma source produces a plasma primarily of hydrogen radicals. The hydrogen pressure may be kept relatively low, for example, at 30 milliTorr. Optionally, helium may be added to the processing gas with the hydrogen partial pressure held below 150 milliTorr. Superior results are obtained with 70% helium in 400 milliTorr of hydrogen and helium. Preferably, an ion filter, such as a magnetic filter, removes hydrogen and other ions from the output of the remote plasma source and a supply tube from the remote plasma source includes a removable dielectric liner in combination with dielectric showerhead and manifold liner.

摘要： An integrated copper deposition process, particularly useful for forming a copper seed layer in a narrow via prior to electrochemical plating of copper, including at least one cycle of sputter deposition of copper followed by sputter etching of the deposited copper, preferably performed in a same sputter chamber. The deposition is performed under conditions promoting high copper ionization fractions and strong wafer biasing to draw the copper ions into the via. The etching may be done with argon ions, preferably inductively excited by an RF coil around the chamber, or by copper ions, which may be formed with high target power and intense magnetron or by use of the RF coil. Two or more cycles of deposition/etch may be performed. A final flash deposition may be performed with high copper ionization and low wafer biasing.

摘要： A multi-step process performed in a plasma sputter chamber including sputter deposition from the target and argon sputter etching of the substrate. The chamber includes a quadruple electromagnetic coil array coaxially arranged in a rectangular array about a chamber axis outside the sidewalls of a plasma sputter reactor in back of an RF coil within the chamber. The coil currents can be separately controlled to produce different magnetic field distributions, for example, between a sputter deposition mode in which the sputter target is powered to sputter target material onto a wafer and a sputter etch mode in which the RF coil supports the argon sputtering plasma. A TaN/Ta barrier is first sputter deposited with high target power and wafer bias. Argon etching is performed with even higher wafer bias. A flash step is applied with reduced target power and wafer bias.
