SDBG 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.


The use of cutting fluid is crucial in the grinding process due to the elevated heat generated during the process which typically flows to the workpiece and can adversely affect its integrity. Considering the conventional technique for cutting fluid application in grinding (flood), its efficiency is related to certain factors such as the type of fluid, nozzle geometry/positioning, flow rate ...

Deep Reactive Ion Etching (DRIE) is a dry plasma process which can etch very narrow, deep vertical trenches into silicon (known as dicing "streets") to separate individual die. Plasma dicing can either occur before grinding (DBG - Dice Before Grind) or after grinding (DAG – Dice After Grind).


DBG (Dicing Before Grinding)*1 process is capable of reducing backside chipping by separating the dies during grinding, which also improves die strength. In addition, because the wafer is separated into dies at the end of the grinding process, a reduction in the risk of wafer breakage can be expected during thin grinding.

DBG (dicing before grinding) process is popular thinning process for ultra-thin chip. But, dicing wafers always causes chip side and surface chipping. This defect on chip faces become source of chip-cracks. SDBG (stealth dicing before grinding) process is a novel process known as SD (stealth dicing) offers a potential defect-free singulation ...


Outline of DBG Process. 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.

(a) BD method (b) SD method (c) Process Flow Fig. 6: Comparison of actual processes In the SD method, stealth dicing is performed from the ground back surface after the back grinding (BG) process.


After that process, the wafer is then inverted and attached to a dicing frame while a grinding process thins out the wafer from the backside until the separation of the wafer into die occurs. The DAG process performs the wafer thinning step first, then attaches the thinned wafer to a taped dicing frame and the etching is performed to create ...


For this reason, if the thickness of a wafer is 50㎛ or less, the process order can be changed. In this case, a Dicing before Grinding (DBC) method is used, where sawing for a wafer is performed to half the level, before the first grinding. In the order of dicing, grinding and dicing, chips are separated safely from wafers.
