This page will show a simple example of a dicing operation and will show how this operation can be implemented in EZ-MES. In this example a serialized wafer is diced into 4 quarters and each of the quarters is individually serialized.

Actual problem

The following figure shows a presentation on how a wafer with Unique ID (Serial Number) W01 moves through a dicing operation that dices the wafer in quarters. After the dicing operation the quartersare serialized: W01-1, W01-2, W01-3 and W01-4

Before we start the configuration, there are a number of things to note:

Configuration / Implementation

The following figure shows a possible implementation for this Wafer dicing operation.

Schematic Flow Diagram for Implementation of Dicing operation in EZ-MES

The configuration consist of the following EZ-MES objects:

Moving a Traveler

The following figure show what will happen when a Traveler moves through the dicing and serialization step:


The following has to be noted:


Please note that in this implemention example some of the configuration naming has been changed but the function remains the same.

Creating Part Definitions

The following Part Definitions will need to be created.  Both parts will need to be 'Discrete' Parts.

  • Wafer Whole
  • Wafer Quarter


Creating Step Definitions

You will now have to create two Step Definitions.  

Step Definition Name: Serialize Whole Wafer and Dice

This Step Definition will contain the 'Input/Output' that configures the incoming part to split into any given amount as the 'Output'.  In our case, we will split the part from 1 to 4.


Step Definition Name: Serialize Wafer Quarters

This Step Definition does not need to contain a 'Input/Output'.  With this Step, the Traveler will now show quantity of attached parts being '4'.

Create a Flow Definition

You will need to create  a Flow Definition that will contain the previously created Step Definitions.

Flow Definition Name: Dice Wafers To Quarters

Add the Step Definitions as shown in the image below.


Your configuration should now be completed.
