Apparatus for cleaning process and method for cleaning process
In a method for cleaning process, a substrate on which a layer is formed may be loaded on a substrate stage. A photocurable resin may be spin coated on the layer to form a photocurable resin layer. Light may be irradiated onto the photocurable resin layer for curing the photocurable resin layer to form a polymer layer containing particles adsorbed from a surface of the layer. The polymer layer containing the particles may be removed.
1 . An apparatus for a cleaning process, comprising:
a chamber;
a substrate stage at a lower portion of an inside of the chamber, and the substrate stage configured to horizontally rotate;
a nozzle structure over the substrate stage in the chamber;
a light source structure configured to face the substrate stage in the chamber; and
a controller,
wherein the light source structure includes
a lamp unit configured to irradiate light, the lamp unit including an emission region including a lamp and a non-emission region including no lamp, and
a protective structure configured to protect the lamp unit and be coupled to the lamp unit, the protective structure including a light blocking portion and an open portion, and
wherein the controller is configured to control the protective structure to selectively block light irradiated from the lamp unit.
2 . The apparatus of claim 1 , wherein the protective structure surrounds at least a portion of a surface of the lamp unit.
3 . The apparatus of claim 1 , wherein the lamp unit is inside the protective structure.
4 . The apparatus of claim 1 , wherein
the lamp is configured to be covered or exposed by a movement of the protective structure or the lamp unit.
5 . The apparatus of claim 1 , wherein
when the emission region of the lamp unit and the light blocking portion of the protective structure overlap each other, the light blocking portion is configured to cover at least the emission region, and
when the emission region of the lamp unit and the open portion of the protective structure overlap each other, at least a portion of the emission region is configured to be exposed through the open portion.
6 . The apparatus of claim 5 , wherein
the emission region and the non-emission region of the lamp unit are alternately and repeatedly arranged, and
the light blocking portion and the open portion of the protective structure are alternately and repeatedly arranged.
7 . The apparatus of claim 6 , wherein
each of the lamp unit and the protective structure has a disk shape, and
the protective structure or the lamp unit is configured to horizontally rotate so that the emission region of the lamp unit and the light blocking portion of the protective structure overlap each other or the emission region of the lamp unit and the open portion of the protective structure overlap each other.
8 . The apparatus of claim 1 , wherein the lamp unit is at an upper portion of an inside of the chamber, and the lamp unit is configured to face the substrate stage.
9 . The apparatus of claim 1 , wherein the nozzle structure includes a nozzle and a driver configured to drive and move the nozzle.
10 . The apparatus of claim 1 , wherein the light irradiated from the lamp unit includes ultraviolet (UV) light or laser.
