发明名称 CLEANING METHOD, METHOD FOR REMOVING FOREIGN PARTICLE, CLEANING APPARATUS AND CLEANING LIQUID
摘要 The present invention provides a mechanism capable of removing a minute particle adhered to a fine pattern or the like without giving damages to the pattern or the like. After being installed on a device which can perform rotating operation, the high viscosity liquid is dropped on an upper surface of an object such as a photomask to be cleaned by a liquid supply part, and then the photomask is rotated to move the high viscosity liquid. During the movement of the high viscosity liquid, a particle adhered to the object such as the photomask is contained in the high viscosity liquid, and is removed. Further, the particle thus contained in the liquid is prevented from re-adhering to the object such as the photomask by controlling a zeta potential of the high viscosity liquid, and is removed from the object such as the photomask. <IMAGE>
