Abstract
Conventionally, in order to hold data with a high sampling rate in a control device, it has been necessary to increase the capacity of ring buffers. A data management method for a semiconductor manufacturing apparatus includes acquiring, by a control device, data related to operation of the semiconductor manufacturing apparatus, identifying, by the control device, first data and second data of the acquired data, writing, by the control device, the first data to a first ring buffer at first temporal granularity and the second data to a second ring buffer at second temporal granularity coarser than the first temporal granularity, and extracting, by a data management device, the first and second data from the first ring buffer and the second ring buffer respectively and storing the first and second data in a database.
