Abstract
A device for sticking adhesive tape to thin articles, such as semiconductor wafers, and trimming excess portions of said tape from the thin articles. A plurality of sticking rollers apply adhesive tape from a roll to each thin article, the tape having an adhesive side oriented towards an upper surface of the article and a width greater than a width of the article. A suction stage receives and holds each of the thin articles with the adhesive tape stuck thereto by said sticking rollers while a tape cutter trims the excess portion of the tape from along peripheral edge portions of the article. A tape peeling device then peels off the trimmed excess portions of the tape from the thin article, whereupon the thin article is conveyed back to a cassette.
