  • Patent number: 9557652
    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.
