  • What Is Mes Manufacturing Execution System In

    requirements for mes in complex discrete manufacturing checkmark or grade on each of the eight functional areas, is not enough to evaluate the fit of an mes to your industry or companys needs. On the surface, many mes seem to have a similarthe stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. during the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.
