    摘要: The invention provides aqueous alkaline compositions useful in the microelectronics industry for stripping or cleaning semiconductor wafer substrates by removing photoresist residues and other unwanted contaminants. The compositions typically contain (a) one or more metal ion-free bases at sufficient amounts to produce a pH of about 10-13 and one or more bath stabilizing agents having at least one pKa in the range of 10-13 to maintain this pH during use; (b) optionally, about 0.01% to about 5% by weight (expressed as % SiO2) of a water-soluble metal ion-free silicate; (c) optionally, about 0.01% to about 10% by weight of one or more chelating agents; (d) optionally, about 0.01% to about 80% by weight of one or more water-soluble organic co-solvents; and (e) optionally, about 0.01% to about 1% by weight of a water-soluble surfactant.

    摘要: A method for cleaning a silicon-based substrate in an ammonia-containing solution without incurring any damages to the silicon surface by NH4OH vapor is described. The method can be conducted by first providing a silicon-based substrate that has a silicon surface, then forming a silicon oxide layer of very small thickness, i.e. less than 10 Å, on the silicon surface. The silicon-based substrate can then be cleaned in an ammonia-containing solution without incurring any surface damage to the silicon, i.e. such as the formation of silicon holes. The present invention novel method can be carried out by either adding an additional oxidation tank before the SC-1 cleaning tank, or adding an oxidant to a quick dump rinse tank prior to the SC-1 cleaning process.

    摘要: A method and apparatus for decomposing a layer of silicon oxide on a silicon wafer is described which employs the application of a heated mist of aqueous HF to the cooled wafer surface. The technique is applied to the analysis of silicon wafers for trace impurities using a scanning fluid drop to collect the residue containing the impurities after the silicon oxide has been decomposed. The novel method offers an order of magnitude increase in the rate of silicon oxide decomposition over the prior art which uses a vapor phase decomposition technique. In addition the novel method provides better control and safer disposition of the corrosive vapors over the prior art. The apparatus comprises a movable dome fitted with a carrier gas supply and a means for injecting a heated aqueous HF mist generated by a specially designed mist generator into the carrier gas flow. The flow mist droplets are drawn from the flow onto the cooled wafer surface providing a thin layer of liquid aqueous HF which reacts with the oxide layer at a faster rate than previously used HF vapor.
