Abstract: A method for manufacturing a graphene thin film for a pellicle material using ozone gas includes a graphene forming step of forming graphene on an upper surface of a substrate, an ozone treatment step of exposing the graphene layer formed in the graphene forming step to ozone, and an etching step of heat-treating and etching the ozone-treated graphene layer.

Abstract: A method for manufacturing the pellicle includes the steps of forming upper and lower silicon nitride layers on opposite surfaces of a wafer substrate, forming a metal layer on the lower silicon nitride layer, etching the upper silicon nitride layer to a preset thickness after the forming of the metal layer, etching and removing the metal layer after the etching of the upper silicon nitride layer, forming a graphene thin film on the upper silicon nitride layer, forming a pattern on the lower silicon nitride layer, etching the lower silicon nitride layer according to the formed pattern, and etching the wafer substrate along the lower silicon nitride layer etched according to the pattern.

Abstract: The present invention relates to a novel indole derivative and a use thereof. The novel indole derivative according to the present invention traps methylglyoxal (MGO), which is a main precursor of advanced glycation end products, and thus can be effectively used for preventing, improving, or treating diseases related to advanced glycation end products.

Abstract: The present invention relates to a composition for preventing, improving, or treating diseases related to advanced glycation end products, comprising an indole derivative or a pharmaceutically acceptable salt thereof. Specifically, the composition of the present invention possesses the effect of trapping methylglyoxal (MGO), which is a main precursor of advanced glycation end products, and thus can be effectively used for preventing, improving, or treating diseases related to advanced glycation end products.
