Abstract: The present invention relates to water-soluble hydrophobically associating copolymers which are obtained in the presence of a nonpolymerizable surface-active compound and which comprise novel hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether block, the polyether block comprising a hydrophilic polyethyleneoxy block and a hydrophobic polyalkyleneoxy block consisting of alkyleneoxy units having at least 4 carbon atoms. The monomers may optionally have a terminal polyethyleneoxy block. The invention further relates to processes for preparing the copolymers and to the use thereof.

Abstract: In a method of treating a substrate including patterns having line-space dimensions of 50 nm or below, the substrate is rinsed by an aqueous composition including at least one non-ionic surfactant A and at least one hydrophobizer B. The at least one surfactant A has an equilibrium surface tension of 10 mN/m to 35 mN/m, determined from a solution of the at least one surfactant A in water at the critical micelle concentration. The hydrophobizer B is selected so that the contact angle of water to the substrate is increased by contacting the substrate with a solution of the hydrophobizer B in water by 5-95° compared to the contact angle of water to the substrate before such contacting.

Abstract: The use of an organic compound as cleavable additive, preferably as cleavable surfactant, in the modification and/or treatment of at least one surface of a semiconductor substrate is described. Moreover, it is described a method of making a semiconductor substrate, comprising contacting at least one surface thereof with an organic compound, or with a composition comprising it, to treat or modify said surface, cleaving said organic compound into a set of fragments and removing said set of fragments from the contacted surface. More in particular, a method of cleaning or rinsing a semiconductor substrate or an intermediate semiconductor substrate is described. In addition, a compound is described which is suitable for the uses and methods pointed out above and which preferably is a cleavable surfactant.

Abstract: The present invention relates to a process for preparing hydrophobically associating macromonomers M and to the novel macromonomers prepared by means of the process according to the invention. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form, the latter consisting of a polyethyleneoxy block and a hydrophobic polyalkyleneoxy block consisting of alkyleneoxy units having at least 4 carbon atoms. Optionally, the macromonomers M may have a terminal polyethyleneoxy block. The macromonomers prepared by the process according to the invention are suitable for reaction with further monomers, especially with acrylamide, to give a water-soluble, hydrophobically associating copolymer.
