Abstract:
A method of creating an electrostatic discharge free component container for storing and transporting components that are used for manufacturing of semiconductor devices, comprising:providing an inner shell, said inner shell comprising polymethylmethacrylate (PMMA), said inner shell having an outer surface, said inner shell having been provided with a cavity, said inner shell having been provided with a front surface, said front surface having been provided with a means for accessing said cavity of said inner shell, said cavity having been provided with a means for positioning said component inside said cavity; providing a metallic layer having a first and a second surface, said first and said second surface having been coated with a layer of polyimide; attaching said metallic layer to said outer surface of said inner shell, completely covering said inner shell with said metallic layer, creating a two layered shell having a cavity, said two layered shell further having outside surfaces, said outside surfaces of said two layered shell having first dimensions in an X, Y and Z direction; and providing an outer shell, said outer shell comprising polymethylmethacrylate (PMMA), said outer shell having a cavity, said outer shell having been provided with a front surface, said front surface having been provided with a means for accessing said cavity of said outer shell, said outer shell further having inside surfaces, said inside surfaces of said outer shell having second dimensions in an X, Y and Z direction, said second dimensions of said out shell being essentially equal to said first dimensions of said two layered shell, thereby completely surrounding said two layered shell with said outer shell, thereby completing creation of an electrostatic discharge free container comprising a cavity that is surrounded by a compound layer of PMMA-Poly covered metal-PMMA, wherein said compound layer of PMMA-Poly covered metal-PMMA prevents both triboelectric charges and induction charges accumulated on said component.
