29-08-2006· Dicing of silicon wafers may also be performed by a laser-based technique, the so-called stealth dicing process. It works as a two-stage process in which defect regions are firstly introduced into the wafer by scanning the beam along intended cutting lines and secondly an underlying carrier membrane is expanded to induce fracture.
In the conventional packaging process of semiconductor manufacturing (TGM, Thin Grinding Mounting), the substrate (wafer) is ground to the designated thickness and then die separation (dicing, cutting process) is performed.
The Dicing Before Grinding (DBG) process has been developed in order to solve this kind of issue. In DBG, first a half-cut is performed on the wafer with a dicing saw. Then, wafer thinning and die separation are performed at the same time during grinding.

Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC).. ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum of ...

Dicing before grinding process(DBG) The wafer is initially grooved by using a Half Cut Dicing process. Subsequently, back grinding is performed until reaching the groove and, thus, separating the dies. Dicing before grinding ensures a perfect backside quality and zero edge chipping.
Dicing is a process for cutting and making grooves using dicing blades. Dicing blades are abrasive blades that use synthetic diamond as the abrasive grit. The outer diameter of the dicing blade is approx. 50 mm and thickness is approx. 0.01 - 0.5 mm. There are various types of blades with different grit sizes, bond materials, and shapes.
