Integrating grinding functions and tape mounting/removal functions into an inline system reduces the frequency of wafer transfer and lowers the risk of wafer-level breakage. In these processing methods, dicing is performed after grinding (polishing) (same as Process Workflow 1).

In the DGB process, die separation is performed by grinding (processing using a grinding wheel), not by dicing (cutting using a blade). The DGB process does not require full-cut dicing or die separation using a blade, so the risk of backside chipping is greatly reduced. Improvement in Die Strength. Die

DBG reverses the usual process of fully dicing the wafer after grinding. In DBG, first the wafer is half-cut with a special dicing saw. Then, die singulation occurs when the wafer is thinned below the level of this cut. The wafer then goes to the in-line DBG Mounter, which gently peels off the protective grinding tape, completing the process.

The adhesive is initially tacky, and then upon irradiation, hardens for ease of release. Any process effective to thin down the wafer can be used. In a particular embodiment, the back side of the wafer is subjected to a grinding operation. Typically, this back-grinding is done to a level to meet the depth of the dicing
Read MoreSDBG is the process of performing backside grinding after Stealth Dicing™ process. It produces narrow streets on thin die and improves die strength. Using a die separator ( DDS Series ) after SDBG, it is possible to precisely separate the DAF (die attach film) which is used as a bonding material when laminating thin die.
