The present invention pertains to a method for producing a graphene-coated steel sheet, the method comprising the steps of: modifying the surface of the steel sheet so that the surface is negatively charged; forming a positively-charged first graphene oxide layer on the surface-modified steel sheet; forming a negatively-charged second graphene oxide layer on the first graphene oxide layer; and heat-treating the steel sheet on which the first and second graphene oxide layers are formed. The present invention provides a graphene coating method which can be easily applied to large-area coating through a simple process without a special dispersant or binder, and has the effect of allowing the excellent physical properties of graphene to be more efficiently exhibited.

A method for wafer treatment is disclosed. A wafer is provided with a main surface, a surface layer, and a base layer. The surface layer is disposed between the main surface and the base layer, and the surface layer covers the base layer and exposes the main surface. Then, at least one laser process is performed to fully irradiate the main surface and the surface layer with a first laser to generate a plurality of optimized regions in the main surface and the surface layer, so that the optimized regions form at least one stress-relieving array.

A film forming method includes preparing a substrate having a first region in which a metal film or an oxide film of the metal film is exposed, and a second region in which an insulating film is exposed, supplying, to the substrate, an organic compound containing, in a head group, a triple bond between carbon atoms represented by Chemical Formula (1) described in the specification, causing the organic compound to be selectively adsorbed in the first region among the first region and the second region, and cleaving the triple bond in the first region and forming a hydrophobic film having a honeycomb structure of carbon atoms through polymerization.

In an embodiment, the present disclosure pertains to a method of forming a self-assembled monolayer coating on a surface of a substrate. In general, the method includes polishing the substrate, cleaning the substrate, and creating a plurality of bonding sites on the surface of the substrate for head groups of an organofunctional silane molecule to bond. In some embodiments, the creating includes at least one of a liquid-phase chemistry process or a dry plasma chemistry process. In some embodiments, the method further includes coating the substrate with a silane coating solution. In some embodiments, the coating is performed in a controlled environment. In some embodiments, the controlled environment includes an anhydrous environment free of at least one of water or moisture. In a further embodiment, the present disclosure pertains to a heat transfer composition having a coating thereon applied via the methods of the present disclosure.
