    Abstract: An apparatus for cutting an adhesive tape attached to a semiconductor wafer and a wafer ring is disclosed. The apparatus includes cutters and rollers. In cutting the adhesive tape, the cutters are aligned on the wafer ring which contains the semiconductor wafer within the wafer ring. The cutters move rolling in a circle along the wafer ring by a rotation of a rotating body, and cut the adhesive tape into two portions. The rollers follow the cutters pressing the inside portion of the tape to secure the adhesion between the adhesive tape and the wafer ring. The apparatus may further include a stationary sensor and marks on the rotating body to control the rotation of the rotating body.
