Cell Cassette management

Challenge

During the cell/module production process, the wafer cassettes are managed centrally and locally. In the case of changes in local production it is important that the management system is flexible and can be rescheduled. If the ID’s on cassettes are readable, but not writable, a complicated program in the host computer is required. It requires considerable effort to take these various possibilities into account and furthermore, it takes time to modify the production line. Even if an unexpected system problem arises, production must continue. Moreover, a production record has to be kept for quality management.

Solution

Omron offers RFID systems with a frequency that conforms to the global standard of 13.56MHz. The ID tags have a large memory, large capacity to rewrite, are resistant to harsh environments and come in compact packages. Therefore it is possible for an ID tag to carry instructions for production. It also simplifies any changes to the production plan. Omron has a fixed and hand-held reader/writer available that enable flexible management while allowing local reading of processed information in attached ID tags.

Benefit

The production records help quality management while flexible production is enabled with respect to change-overs.
