摘要:
Disclosed is a liquid chemical for forming a water-repellent protecting film on a wafer. The liquid chemical is a liquid chemical containing a water-repellent-protecting-film-forming agent for forming the water-repellent protecting film, at the time of cleaning the wafer which has a finely uneven pattern at its surface and contains at least at a part of a surface of a recessed portion of the uneven pattern at least one kind of matter selected from the group consisting of titanium, titanium nitride, tungsten, aluminum, copper, tin, tantalum nitride, ruthenium and silicon, at least on the surface of the recessed portion. The liquid chemical is characterized in that the water-repellent-protecting-film-forming agent is a water-insoluble surfactant. The water-repellent protecting film formed with the liquid chemical is capable of preventing a pattern collapse of the wafer, in a cleaning step.

The working fluid composition for a refrigerating machine according to the invention comprises the refrigerating machine oil, a difluoromethane refrigerant and/or an unsaturated fluorinated hydrocarbon refrigerant.
摘要:
A silicon wafer cleaning agent includes at least a water-based cleaning liquid, and a water-repellent cleaning liquid for providing water-repellent to an uneven pattern at least at recessed portions during a cleaning process. The water-repellent cleaning liquid is a liquid composed of a water-repellent compound containing a reactive moiety which is chemically bondable to Si in the silicon wafer, and a hydrophobic group, or is a liquid wherein 0.1 mass % or more of the water-repellent compound relative to the total quantity of 100 mass % of the water-repellent cleaning liquid and an organic solvent are mixed and contained therein. A cleaning process wherein a pattern collapse is easily induced can be improved by using the cleaning agent.
