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

eRetic

l

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
