WebStealth dicing is a process that can reduce heat transfer during cutting. It cuts the upper surface of the wafer without producing any crack on it by using bare Si. Bare Si does not allow heat transfer because of its special properties. The order quantity must be high enough in this as well to get the advantage of reducing heat transfer. WebIn the SD method, stealth dicing is performed from the ground back surface after the back grinding (BG) process. In contrast to conventional dicing where the chips are completely separated during blade dicing (BD), the SD method allows the individual chips to be still integrated with the wafer even after stealth dicing.
