Abstract:
1. A method of measuring a heating plate temperature in a substrate processing device provided with a carrier take-in portion taking in a carrier accommodating a plurality of substrates, a processing unit including a heating unit placing said substrate on said heating plate and performing heat treatment on said substrate, and a transporting portion receiving said substrate from the carrier take-in portion and transporting said substrate to said processing unit, wherein said method includes: a step of transporting said temperature detection substrate including a temperature detecting portion, a storing portion and a substrate controller through a predetermined transportation path to said heating unit by said transporting portion; a start instruction providing step of providing a temperature measurement start instruction to the substrate controller of said temperature detection substrate in a predetermined position on said transportation path; a step of receiving said temperature measurement start instruction and storing time-series data of a detected temperature value in said storing portion by said temperature detection substrate; and a time-series data fetching step of fetching the time-series data of said detected temperature value obtained after placement of said temperature detection substrate on said heating plate based on a transportation time from the provision of said temperature measurement start instruction to the placement of said temperature detection substrate on said heating plate and the time-series data of the detected temperature value in said storing portion.
