Abstract:
In an example, a wet cleaning process is performed to clean a structure having features and openings between the features while preventing drying of the structure. After performing the wet cleaning process, a polymer solution is deposited in the openings while continuing to prevent any drying of the structure. A sacrificial polymer material is formed in the openings from the polymer solution. The structure may be used in semiconductor devices, such as integrated circuits, memory devices, MEMS, among others.

Claim (Index 15):
A semiconductor processing method, comprising:\n forming a plurality of features in a structure using a dry removal process; performing a wet cleaning process to remove residue left from the dry removal process from openings between the features; displacing liquid from the wet cleaning process in the openings with a first solvent; displacing the first solvent in the openings with a polymer solution comprising a second solvent and a polymer resin; baking the polymer solution to remove at least some of the second solvent to form a sacrificial polymer material in the openings, wherein the sacrificial polymer material comprises the polymer resin and at least a remainder of the second solvent; removing the sacrificial polymer material; and forming an additional material in the openings after removing the sacrificial polymer material.
