Radio Frequency IdentificationTechnology that uses devices
attached to objects that transmit data to a (RFID) receiver. Alternative to
bar coding.
Advantages:read/write capability.data capacity. no line-of-sight needed.

the clean room
IntroductionA Fab is a factory where integrated
circuits devices are manufactured.
Fab18 - Intel’s 200mm Fab located in Kiryat Gat, Israel.
The project deals with building a system for reliable handling of reticles in the clean room of Fab18.
Intro (cont) & basic termsReticle - An optical template inserted into the manufacturing machines in the Lithography area.
Reticl

eLithography = The process of imprinting patterns
The production process for a single silicon wafer can take as much as a few months.
WaferWafer
Wafer = silicon slice (raw material)
Current Situation
“Railway” Tracks in the clean room’s
ceiling
A single lot
Being
transported
Lot = pack of 25 silicon wafers
The ProblemRecently Intel’s Fab18 started using a new manufacturing technology. For this technology new reticles are used.
The new reticles are larger and don’t fit in the old reticle storing and transportation system.
The technicians manually bring the reticles from the storage room to the work stations.
Human errors can occur. Reticles may get lost (reticle cost can reach to 150K $). No control.
The project aims at providing the ability to control the movement of the reticles.
The SolutionConstruct an integrative system which includes hardware and software using RFID technology.
The project's hardware includes shelves with RFID readers, placement sensors and led indicators. Additionally it includes a gate with an RFID reader. The employees have RFID chip on their tags, and so do the reticles.
Our system allows the technician to place an order for a specific reticle, identify the technician as he passes through the gate, and indicate the location of the desired reticle.
When a technician returns a reticle the system identifies it and updates the data accordingly.
Our system includes new Databases, Graphic User Interface, and a controller component for the entire system.
The solution – The Shelves
Shelves
example
System Architecture
The MTUI system is an interface for the technician in the clean room. The technicians use it to create orders for Reticles
The orders from the MTUI are transferred to the RTS and its WART Database (Oracle).
The Control System is
responsible for the
communication between the
different components and for
the logic.
The Control System
interacts with the CDIS
(Intel’s employee DB)

Use Cases
User Interface (1)
• Administrator Page:Used to create and update associations between RFID tags and Reticles.
When a RFID tag is placed in the RFID
reader, the reader
reads its data and
the tag ID is displayed to
the user
2 options for the user
User Interface (2)
• MTUI Simulator – Making an order:
User Interface (3)
• Gate Simulator :

“Enter the gate” event
User Interface (4)
• Shelves Simulator:
