摘要： A magnetron plasma etching apparatus comprises a suscepter serving as an electrode on which a silicon wafer is mounted. A carbon ring having an outer diameter larger than the diameter of the wafer and an electrical resistance lower than that of the wafer, is arranged around the suscepter. The carbon ring is electrically connected to the suscepter. The carbon ring improves uniformity of etching of the wafer.

摘要： A dual damascene trench etching process includes a two-step BARC etching process, a first BARC etch step using a fluorocarbon-based plasma, and a second BARC etch step using an O2/N2-based plasma. The first BARC etch step removes a first portion of the BARC covering a dielectric stack using a fluorocarbon-based plasma. The second BARC etch step removes a second portion of the BARC covering the dielectric stack using a O2/N2 based plasma. The dual damascene trench etching process may further include a BARC etch back process to remove a further portion of the BARC not covering the dielectric stack. The dual damascene trench etching process further includes a low-k dielectric etching process that etches trenches in a low-k dielectric layer in the dielectric stack and that avoids the use of argon in order to prevent facet formation.

摘要： A method of etching silicon oxide with high selectivity to a photoresist mask and to a silicon-containing substrate comprising exposing the silicon oxide to a plasma of a precursor etch gas of a fluorocarbon and an organic silane containing at least one organic group. When at least about 10% by weight of the silane is present in the etch gas, the selectivity between the silicon oxide and the photoresist mask layer, and between the silicon oxide and the silicon-containing substrate, increases markedly. High aspect ratio, submicron size openings can be etched.
