Abstract:
A method of manufacturing semiconductor devices, using a wafer carrier having conditioning units to control internal conditions of said wafer carrier, said wafer carrier storing wafers and carrying them between manufacturing equipments used in a series of manufacturing processes, the method comprising, for each of the manufacturing processes:placing said wafer carrier on a load port that automatically opens and closes a lid of said wafer carrier; transferring said wafers from said wafer carrier into said manufacturing equipment through said load port; changing operating conditions of said conditioning units according to a process or test being carried out by said manufacturing equipment on said wafers; returning said wafers into said wafer carrier through said load port after a completion of the process or test; and operating said conditioning units according to the changed operating conditions to control internal conditions of said wafer carrier until said wafer carrier with said wafers is carried to a manufacturing equipment of a next manufacturing process.
