Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes treating modules having an opening for taking in and taking out a substrate and which are stacked on each other; and an air flow generating member for generating a downward airflow at each treating module, and wherein the air flow generating member includes: a pan unit configured to supply an air; a spray unit configured to be provided above the treating module and which sprays an air supplied from the pan unit; and an exhaust unit configured to exhaust an air sprayed by the spray unit to outside of the treating module.

Abstract: Provided are a control method, a control apparatus, a training method, and a training apparatus based on thickness estimation of a wafer substrate. The training method includes generating a training spectrum signal according to a thickness of a wafer substrate using an optical model, generating a training spectrum signal having a noise by applying a noise based on a noise parameter to the training spectrum signal, calculating a similarity between the training spectrum signal having the noise and an actually measured spectrum signal, and when the similarity satisfies a set condition, training a noise reduction model using the training spectrum signal having the noise.

Abstract: A method of providing design feedback comprises the steps of: storing design behavior information of a user for a target design; and comparing current design behavior information with previous design behavior information to provide the user with feedback on the current design behavior information, wherein the design behavior information includes at least one of a sketch drawing generated by a design sketch, a design reference search range, and a design reference identified by the user.

Abstract: Disclosed herein is a composite panel for sound absorption that may absorb and block noise. The composite panel may include: a first perforated panel comprising first embosses and first perforation groups formed in a predetermined pattern, wherein the first embosses are formed by forming a plurality of cells and the first perforation groups are formed by collecting a plurality of first perforated holes; an embossed panel comprising second embosses formed by forming the plurality of cells and coupled to the first perforated panel wherein the embossed panel is laminated with the first perforated panel; and a sound absorbing and insulating material inserted between the first perforated panel and the embossed panel.
