A dummy database in which a treatment history of each of the dummy wafers is associated with the carrier is held in a storage part. The treatment history of each of the dummy wafers registered in the dummy database is displayed on a display part of the heat treatment apparatus. An operator of the heat treatment apparatus views the displayed information to thereby appropriately grasp and manage the treatment history of each of the dummy wafers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Heat treatment method and heat treatment apparatus for managing dummy wafer","description":"When a carrier storing a plurality of dummy wafers therein is transported into a heat treatment apparatus, the carrier is registered as a dummy carrier exclusive to the dummy wafers.
