  • Patent number: 8119020
    Abstract: A method for manufacturing an electronic device using a closed-type transport container, includes: controlling relative humidity inside the closed-type transport container to be lower than ambient relative humidity outside the closed-type transport container on a particular interprocess transport path in which an intermediate product stored in the closed-type transport container is transported from a first manufacturing process to a second manufacturing process. The first manufacturing process allows basic compounds containing nitrogen atoms to be released from the intermediate product. The second manufacturing process is susceptible to degradation due to contamination by the basic compounds.
