Abstract
A wafer carrier for use in the transportation and storage of semiconductor wafers. More particularly, the invention is a wafer carrier having both a rigid structure and a corrosion resistant coating. The wafer carrier includes a unitary frame having several wafer supports joined by connecting members. The frame is coated with a material, such as a fluoropolymer, which is resistant to corrosive materials typically used in semiconductor fabrication processes.
