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. WebStealth dicing is a zero-waste, dry process which does not require any cleaning. Kerf width can be drasticly reduced. Stealth Laser can be applied to multi-project-wafers (MPW) or MEMS and various materials, as the dry … butler cc football forfeit

"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.
