2. Description of the Related Art As a dicing method for a semiconductor wafer, for example, a semiconductor wafer having a wiring pattern formed on an upper surface of an adhesive tape for dicing is attached to a ring frame, and a wafer mounting frame is formed. A method is employed in which the semiconductor wafer is held on a chuck table of a dicing apparatus and is diced along a cut line of a semiconductor wafer by a rotating blade or the like of the dicing apparatus.

[0003] This dicing method includes a so-called full-cut method in which the dicing depth is larger than the thickness of the semiconductor wafer and cutting is performed to the adhesive tape for dicing. There is a method called a semi-full cut method, which is slightly smaller than that. In the case of the full cut method, the semiconductor wafer is divided into individual semiconductor elements (chips) at the time of completion of dicing, and therefore, an adhesive tape for dicing is required for supporting the semiconductor wafer. Also, in the semi-full cut method,
Since the semiconductor wafer after dicing is extremely fragile,
Support with an adhesive tape for dicing is required.
And for holding the dicing adhesive tape,
A ring frame is used.

[0004] However, as the diameter of the semiconductor wafer increases, if the above dicing method is applied to the semiconductor wafer having a large diameter, the ring frame becomes large and the weight increases. For this reason, the mount frame manufacturing apparatus, the dicing apparatus, and the bonding apparatus for processing the same are increased in size, which makes it difficult to handle and transport by hand. This problem will become more serious as the diameter of semiconductor wafers becomes larger in the future.
