    • A raw sheet L, in which a strip-shaped tape base material TB having a die bonding sheet portion DS with a size of substantially corresponding to the shape of a semiconductor wafer W is temporarily stuck to a strip-shaped release liner S, is fed out, and a cut-line detecting device 14 detects whether any cut-line C is already formed on the outer circumference side of the die bonding sheet portion DS, on the pathway of the feeding out. According to the result of detection, the die cutting device 13 lets the raw sheet L pass straight through without forming any cut-line C when the cut-line C is judged to be already formed thereon. On the other hand, the die cutting device 13 forms a cut-line C to form a sticking tape DDT when no cut-line C is detected. The sticking tape DDT is peeled by a peeling device 15 to be stuck to the ring frame RF in the position that the die bonding sheet portion DS is to be corresponding to the semiconductor wafer W.
    • 将具有基本上对应于半导体晶片W的形状的芯片接合片部分DS的条状带基材TB临时粘贴到条形剥离衬垫S的原料片L被供给 并且切断线检测装置14检测在送出的通路上是否在芯片接合片部分DS的外周侧上形成了任何切割线C. 根据检测结果,当切断线C被判断为已经形成在其上时,模切装置13使原料片L直线穿过而不形成任何切割线C. 另一方面,当没有检测到切割线C时,模切装置13形成切割线C以形成粘着带DDT。 粘贴带DDT由剥离装置15剥离以粘贴到环形框架RF上,使得芯片接合片部分DS将对应于半导体晶片W.

    • There is provided a sheet peeling apparatus and a peeling method using a plurality of peeling units capable of performing peeling off operation under optimum condition in accordance with the material, thickness or the like of a protective sheet. A sheet peeling apparatus 10 for peeling off a sheet S stuck on the surface of a semiconductor wafer W by using an adhesive tape T of a width narrower than that of the sheet S, which is equipped with a peeling head 15 (second peeling unit) for peeling off the sheet S by pulling the adhesive tape T in an obtuse angled direction in a state stuck to the end portion of the sheet; and first and second rollers 21, 22 (first peeling unit) for peeling off the sheet S by pulling the adhesive tape T in the substantially right angle or acute angle direction in a state stuck with the adhesive tape T in the direction across the sheet S. Either one of the peeling units are selectively used in accordance with the type of the sheet S.
    • 提供了一种片材剥离装置和使用多个剥离装置的剥离装置,该剥离装置能够根据保护片的材料,厚度等在最佳条件下进行剥离操作。 通过使用宽度窄于片材S的宽度的粘合带T,剥离粘附在半导体晶片W的表面上的片材S的片材剥离装置10,其具有剥离头15(第二剥离单元) 用于通过在粘贴到片材的端部的状态下将胶带T拉成钝角度方向来剥离片材S; 以及第一和第二辊21,22(第一剥离单元),用于通过在粘合带T的状态下沿着片材S的方向拉动粘合带T以大致直角或锐角方向剥离片材S. 根据片材S的类型选择性地使用任一个剥离单元。
