Abstract: The present disclosure relates to cleaning compositions that are used to clean semiconductor substrates. These cleaning compositions can remove the defects/contaminants arising from previous processing on the semiconductor substrates and thereby make the substrates appropriate for further processing. The cleaning compositions described herein primarily contain at least one pH adjusting agent and at least one biosurfactant.

Abstract: The present disclosure is directed to etching compositions that are useful for, e.g., selectively removing silicon germanium (SiGe) from a semiconductor substrate as an intermediate step in a multistep semiconductor manufacturing process.

Abstract: This disclosure relates to a polishing composition that includes at least one abrasive; at least one nitride removal rate reducing agent, an acid or a base; and water. The at least one nitride removal rate reduce agent can include a hydrophobic portion containing a C4 to C40 hydrocarbon group; and a hydrophilic portion containing at least one group selected from the group consisting of a sulfinite group, a sulfate group, a sulfonate group, a carboxylate group, a phosphate group, and a phosphonate group; in which the hydrophobic portion and the hydrophilic portion are separated by zero to ten alkylene oxide groups. The polishing composition can have a pH of from about 2 to about 6.5.

Abstract: This disclosure relates to a method that includes applying a polishing composition to a surface of a substrate; bringing a pad into contact with the surface of the substrate and moving the pad in relation to the substrate to create a polished substrate; treating the polished substrate with a rinse solvent; flowing a vapor over a meniscus formed at an interface between air and the rinse solvent on the polished substrate. The vapor includes a first component containing a water miscible organic solvent, a second component containing a cleaning agent, and a third component containing an inert gas.
