摘要:
A nozzle for discharging droplets of a processing liquid for processing a substrate has a main body including a supply port, a drain port, a processing liquid flow passageway connecting the supply port and the drain port, and a plurality of discharge ports from which the processing liquid is discharged. The processing liquid flow passageway includes a plurality of branch flow channels, which branch out between the supply port and the drain port and collect together between the supply port and the drain port. The plurality of discharge ports form a plurality of columns respectively corresponding to the plurality of branch flow channels; and are aligned along and connected to the corresponding branch flow channels. A piezo element applies vibration to the processing liquid flowing through the plurality of branch flow channels.

A substrate treatment apparatus includes: a substrate holding unit which horizontally holds a substrate; a liquid droplet nozzle which generates droplets of a treatment liquid which are sprayed on a spouting region on an upper surface of the substrate held by the substrate holding unit; and a protective liquid nozzle which spouts a protective liquid obliquely onto the upper surface of the substrate held by the substrate holding unit for protection of the substrate to cause the protective liquid to flow toward the spouting region on the upper surface of the substrate, whereby the spouting region is covered with a film of the protective liquid and, in this state, the treatment liquid droplets are caused to impinge on the spouting region.

摘要:
A light source device which is used as the backlight device and does not generate sound is provided. One or more flat substrates each having a light emitting element on its surface side are supported by a chassis having a conductive flat plate surface so that back surfaces of the substrates are opposed to the flat plate surface. The substrate comprises first wiring conductive thin films on a surface side of an insulation substrate, and one or more second radiating or wiring conductive thin films on a back surface side of the insulation substrate. Two terminals of the light emitting element are connected to the two adjacent first conductive thin films. A potential of at least one of the second conductive thin films is fixed to have a constant potential difference or preferably fixed to the same potential with respect to that of the flat plate surface of the chassis.
