Abstract: An apparatus for chemical mechanical polishing includes a rotatable platen having a surface to support a polishing pad, a carrier head to hold a substrate in contact with the polishing pad, and a polishing liquid distribution system. The polishing liquid distribution system includes a dispenser positioned to deliver a polishing liquid to a portion of a polishing surface of the polishing pad, and a curved barrier positioned after the dispenser to spread fresh polishing liquid from the dispenser.

Abstract: Provided is a wall assembly for goods display constituted by horizontal tracks fixed to a wall body and disposed in a lateral direction at equal intervals, vertical posts disposed on the horizontal tracks and disposed in a vertical direction at equal intervals, an interval adjustment unit configured to couple the vertical post with respect to the horizontal track to adjust an interval, an insert member inserted into the vertical post in the vertical direction, and an outer panel coupled to the vertical post. Accordingly, even when flatness of the wall body is bad, the wall assembly can be instructed and the flatness of the panel after construction can be appropriately maintained so that an appearance of a wall surface can be excellently finished. In addition, since removal and exchange of only a damaged panel are easy when the outer panel is damaged, construction and exchange can be easily performed.
