Methods include evaporating a functionalized polyhedral oligomeric silsesquioxane onto a first major surface. Methods include impinging an ion beam on the first major surface. Alternatively, methods include disposing and heating a solution comprising a polysilazane or a polyhedral oligomeric silsesquioxane on a first major surface. In aspects, methods include reacting material at the first major surface with a alkyl silane.

The present disclosure relates to a substrate processing method, and more particularly, to a substrate processing method for improving the physical properties of a thin film formed on a substrate. An embodiment of a substrate processing method according to the present disclosure comprises the steps of: carrying a substrate into a first chamber; a first pressurizing step increasing the pressure in the first chamber so that the pressure in the first chamber reaches a first high-pressure that is higher than the normal pressure; a first depressurizing step decreasing the pressure in the first chamber so that the pressure in the first chamber reaches a second high-pressure that is lower than the first high-pressure and equal to or higher than the normal pressure; a first pressurizing/depressurizing repeating step performing the first pressurizing step and the first depressurizing step repeatedly at a predetermined number of times; and a second depressurizing step decreasing the pressure in the first chamber so that the pressure in the first chamber reaches a first low-pressure that is lower than the normal pressure.
