WebJan 1, 2015 · Stealth dicing is a clean and dry singulation method and is effective for dicing MEMS wafers with exposed structures, thin membranes, or other highly sensitive surface features. Stealth dicing focuses a laser beam below the surface along the dicing street. The wavelength of the laser is specific to the material being cut so that the laser light ...
WebStealth dicing is a laser cutting method that uses light at a semi-transparent wavelength to penetrate the substrate surface and cut it from the inside out. To start, the wafer is mounted to an adhesive to prevent any unwanted movement. The process begins by targeting the midpoint of a wafer to make a small crack that does not reach the surface. orderly liquidation meaningWebMar 29, 2024 · Stealth Dicing (SD) technology has high potential to replace the conventional blade sawing and laser grooving.
