"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. " - Stealth dicing
