In a method of coating a photoresist, the photoresist may be provided to an upper surface of a rotating wafer. A hovering solution may be injected to an edge portion of the photoresist under a condition that the hovering solution may be hovered with respect to the edge portion of the photoresist with an air layer being interposed between the hovering solution and the edge portion of the photoresist to limit and/or prevent a bead of the photoresist from being formed on an edge portion of the upper surface of the wafer. Thus, the photoresist having a uniform thickness may be coated on the upper surface of the wafer to improve a yield of a semiconductor device by increasing an effective area of the edge portion of the wafer.

Method of coating a photoresist and apparatus for performing the same

Disclosed is an electronic device which a camera, a memory, and a processor that is operatively connected with the camera and the memory. The processor performs photographing on an external object multiple times depending on a second exposure time shorter than a specified first exposure time by using the camera, obtains a first image set including a plurality of first images depending on the multiple photographing, composes the first image set to generate a second image, identifies a specific area around at least one light source corresponding to a light source included in the second image, and generates a third image where an image effect associated with the light source is added to the specific area, by using the second image. Moreover, various embodiment found through the present disclosure are possible.

Image processing method and electronic device supporting same

A wearable device according to various embodiments of the present disclosure may include a housing forming at least a part of an exterior of the wearable device, a plurality of openings formed in at least a partial region of the housing, an elastic body disposed inside the housing and including a passage spatially connected with the plurality of openings, and at least one microphone sensing vibration introduced from the outside via the plurality of openings and the passage.

Wearable device comprising microphone for obtaining sound by using plurality of openings

An electronic device includes a housing including a front plate forming a first surface, a back plate forming a second surface, and a side member forming a side surface surrounding a space between the first and second surfaces; a sound output device disposed in the housing; an electrical component disposed in the housing and having a variable thickness; and a vibration damping member disposed on at least part of the electrical component or formed between the electrical component and the back plate. The vibration damping member is disposed in a variable space having a thickness varying depending on a thickness variation of the electrical component. The vibration damping member has a height varying in a thickness direction of the variable space to correspond to the thickness of the variable space and divides the variable space into a plurality of sub-spaces when the variable space has a specified thickness or more.
