Abstract: An apparatus and method for processing a substrate can reduce the concentration of process by-products in a chemical solution.

Abstract: The electronic device for recommending an AI-based melanoma biopsy site according to an exemplary embodiment of the present invention includes a processor which classifies a skin image that is input by using a classification model as melanoma or nevus, identifies melanoma features in the skin image by using a generation model when the skin image is classified as melanoma to generate an image from which the melanoma features are removed, and compares the skin image with the generated image to identify at least one candidate biopsy site.

Abstract: Disclosed are an electrode slurry for a fuel cell capable of forming a multilayer structure without an interface using a first support and a second support having different mesopore fractions and densities, a multilayer electrode structure using the same, and a manufacturing method thereof. The electrode slurry for a fuel cell includes a first catalyst including a first support on which a first metal is supported, a second catalyst including a second support on which a second metal is supported, an ionomer, and a solvent, the first support and the second support having different mesopore fractions and densities.

Abstract: Discussed are a light-emitting device and a light-emitting display device having improved efficiency and increased lifespan. A plurality of stacks is provided between an anode and a cathode for at least a subpixel to emit a predetermined color, and emissive layers in different stacks include the same color-based materials having different luminous properties.

Abstract: Disclosed is a method of forming an area-selective thin film, the method comprising supplying a nuclear growth retardant to the inside of the chamber in which the substrate is placed, so that the nuclear growth retardant is adsorbed to a non-growth region of the substrate; purging the interior of the chamber; supplying a precursor to the inside of the chamber, so that the precursor is adsorbed to a growth region of the substrate; purging the interior of the chamber; and supplying a reaction material to the inside of the chamber, so that the reaction material reacts with the adsorbed precursor to form the thin film.

Abstract: A method for manufacturing an organic light emitting diode (OLED) display includes forming a first electrode having different thicknesses corresponding to a first pixel, a second pixel, and a third pixel, forming a first emission layer, a second emission layer, and a third emission layer respectively corresponding to the first pixel, the second pixel, and the third pixel, and forming a second electrode on the first emission layer, the second emission layer, and the third emission layer, wherein forming the first electrodes includes forming a first electrode material layer on the substrate, forming a photoresist pattern having different thicknesses corresponding to the first pixel, the second pixel, and the third pixel, respectively, and etching the first electrode material layer along with the photoresist pattern.
