摘要:
A liquid chemical for forming a water repellent protecting film on a wafer having at its surface an uneven pattern and containing at least one kind of element selected from the group consisting of titanium, tungsten, aluminum, copper, tin, tantalum and ruthenium at surfaces of recessed portions of the uneven pattern, the water repellent protecting film being formed at least on the surfaces of the recessed portions. The liquid chemical is characterized by including: a water repellent protecting film forming agent; and water, and characterized in that the water repellent protecting film forming agent is at least one selected from compounds represented by the following general formula [1] and salt compounds thereof and that the concentration of the water relative to the total quantity of a solvent contained in the liquid chemical is not smaller than 50 mass %.
摘要:
The invention provides a method for cleaning a soiled substrate, the method comprising the treatment of the moistened substrate with a formulation comprising a multiplicity of polymeric particles, wherein the polymeric particles are applied in combination with a detergent formulation, the method being characterized in that the detergent formulation is divided into its separate chemical constituents and these chemical constituents are added at different times during the wash cycle. The method allows for improved cleaning with reduced overall chemical loading, and facilitates addition of the more expensive parts of the formulations when they are most effective for cleaning performance, thereby providing considerable cost savings in comparison with conventional all-in-one detergent formulations. A method for cleaning the polymeric particles is also provided.

摘要:
Methods for using improved stripper solutions having dimethyl sulfoxide; a quaternary ammonium hydroxide; an alkanolamine having at least two carbon atoms, at least one amino substituent and at least one hydroxyl substituent, with the amino and hydroxyl substituents being attached to two different carbon atoms; and a surfactant. Some formulation can additionally contain a secondary solvent. The stripper solutions are effective for removing photoresists from substrates, and typically have freezing points below about +15° C. and high loading capacities.
摘要:
The present invention provided amphoteric detergent compatible amphoteric softeners based on alkyl ammonium backbone of formula 1, 2 or 3. These softeners may be used directly to impart softness to the substrates such as fabrics. The invention also provides a method for preparation of these softeners by reaction of maleic anhydride with a mixture of long chain alcohols or glycols and then with a mixture of amine and olefinic acid and a polymerization inhibitor. The softeners of the present invention are used as such or in combination with cationic as well as anionic additives without any special additive. These softeners do not impart additional yellowing characteristics to the fabric.

The present invention relates to compositions comprising ethyleneoxide butyleneoxide and a galactomannan such as guar. The compositions are particularly well suited for ophthalmic applications such as contact lens disinfection and rewetting. Methods for the treatment of dry eye using the compositions of the present invention are also contemplated.
摘要:
Fatty amine compositions made from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives are disclosed. In another aspect, fatty amidoamines made by reacting a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with an aminoalkyl-substituted tertiary amine are disclosed. The fatty amines or amidoamines are advantageously sulfonated, sulfitated, oxidized, or reduced. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin.
