    Abstract: A pressure is maintained within a volume within which a semiconductor wafer resides at a pressure that is sufficient to maintain a liquid state of a precursor fluid to a non-Newtonian fluid. The precursor fluid is disposed proximate to a material to be removed from the semiconductor wafer while maintaining the precursor fluid in the liquid state. The pressure is reduced in the volume within which the semiconductor wafer resides such that the precursor fluid disposed on the wafer within the volume is transformed into the non-Newtonian fluid. An expansion of the precursor fluid and movement of the precursor fluid relative to the wafer during transformation into the non-Newtonian fluid causes the resulting non-Newtonian fluid to remove the material from the semiconductor wafer.

  • Patent number: 8309472
    Abstract: A method for fabricating semiconductor devices includes providing a semiconductor substrate having a surface region containing one or more contaminants and having an overlying oxide layer. In an embodiment, the one or more contaminants are at least a carbon species. The method includes processing the surface region using at least a wet processing process to selectively remove the overlying oxide layer and expose the surface region including the one or more contaminants. The method includes subjecting the surface region to a high energy electromagnetic radiation having wavelengths ranging from about 300 to about 800 nanometers for a time period of less than 1 second to increase a temperature of the surface region to greater than 1000 degrees Celsius to remove the one or more contaminants. The method includes removing the high energy electromagnetic radiation to cause a reduction in temperature to about 300 to about 600 degrees Celsius in a time period of less than 1 second.
