The thermal processing apparatus includes a chamber having a processing zone therein, a plurality of chuck pins configured to support a substrate and move up or down individually, a heater configured to provide heat energy to the processing zone, a fluid supply port configured to supply a fluid to the processing zone, a fluid discharge port configured to discharge the fluid remaining in the processing zone to the outside, and a controller configured to control a treatment process of the substrate.

Abstract: A coil component includes a body including a first surface and a plurality of side surfaces respectively connected to the first surface, a substrate disposed in the body, a coil portion disposed in the body, a lead-out portion disposed in the body and connected to the coil portion, and a dummy portion spaced apart from the lead-out portion. The body includes four corners, at each of which two adjacent side surfaces of the first to fourth side surfaces are in contact with each other, and the dummy portion includes first to fourth dummy patterns respectively disposed outside the coil portion and extending toward the four corners of the body.

Abstract: A coil component includes a body having a first surface and a second surface opposing each other and a plurality of wall surfaces connecting the first surface to the second surface, and including insulating resin and magnetic metal powder particles; an insulating substrate disposed in the body; a coil portion disposed on the insulating substrate and including a lead-out pattern exposed to a first wall surface of the plurality of wall surfaces of the body; and an external electrode disposed on the body and connected to the lead-out pattern. Some of the magnetic metal powder particles are exposed to each of the plurality of wall surfaces of the body. The magnetic metal powder particles exposed to the first wall surface of the body have a cut-out surface. The magnetic metal powder particles exposed to a second wall surface connected to the first wall surface of the plurality of wall surfaces of the body do not have a cut-out surface.
