Wafer warpage is one of the main concerns during the wafer backgrinding process. Insufficient vacuum may cause nonplanar wafer in contact with the chuck table that may result to poor grinding and broken wafer. Wafer backgrinding stress and backgrinding tape tension also contribute to the effect on wafer warpage. Challenges exist in processing different silicon wafer technology, particularly ...

Backgrinding is the process of removal of silicon from the back of wafers following conventional semiconductor processing. The process is primarily utilized in thinning wafers for commercial semiconductor wafer fabs. Wafers are first laminated using an automatic taping machine. After inspection, they are placed on a Disco 84X series infeed grinder.

 · Backgrinding is the conventional method for reducing Si wafers to a diminished thickness suitable for final packaging. The processed wafer is first cleaned and dried. Next, a protective tape is applied to the front side to avoid any damages to the designed circuits. The wafers are then placed in cassettes and later centred on a porous ceramic vacuum chuck for backgrinding operation. The .
