Abstract: A tray module includes a first protective film, a second protective film, a cover film, and a tray. The first protective film includes a first adhesive layer. A loading target part is in contact with a bottom surface of the first adhesive layer. The second protective film includes a second adhesive layer. The loading target part is in contact with an upper surface of the second adhesive layer. The cover film is in contact with a portion of the second adhesive layer exposed by a distance (e.g., a predetermined or selectable distance) from an edge of the first protective film in a direction. Since the loading target part is fixed to the tray by the cover film instead of the protective films, contamination of the loading target part or the tray due to the first adhesive layer or the second adhesive layer may be prevented.
