What inspired this Wish List Request?
This was requested by a customer in Japan from Tokyo Electron Miyagi Ltd.
Please describe the new or improved feature or solution you would like to see.
Y axis of the Wafer maps from Hierarchical clustering is reversed(higher value on the bottom).
Please run the script below.
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Wafer Stacked.jmp" );
obj = dt << Hierarchical Cluster(
Y( :Defects ),
Object ID( :Lot, :Wafer ),
Attribute ID( :X_Die, :Y_Die ),
Method( "Ward" ),
Standardize Data( 0 ),
Cluster Summary( 1 ),
Dendrogram Scale( "Distance Scale" ),
Number of Clusters( 7 ),
Add Spatial Measures( Attributes( 1 ), Angle( 1 ), Radius( 1 ), Streak Angle( 1 ), Streak Distance( 1 ) ),
SendToReport(
Dispatch( {}, "Dendrogram", OutlineBox, {Close( 1 ), SetHorizontal( 1 )} ),
Dispatch( {"Dendrogram"}, "Clust Dendro", FrameBox, {Frame Size( 35, 700 )} )
),
Save Clusters
);
Close( "Wafer Stacked Defects Spatial" );
dt << select where( :Cluster == 6 );
dt2 = dt << subset( selected rows, all columns );
dt2:X_Die << Set Modeling Type( "Nominal" );
dt2:Y_Die << Set Modeling Type( "Nominal" );
dt2 << Graph Builder(
Size( 567, 428 ),
Show Control Panel( 0 ),
Variables( X( :X_Die ), Y( :Y_Die ), Color( :Defects ) ),
Elements( Heatmap( X, Y, Legend( 7 ) ) ),
SendToReport(
Dispatch( {}, "400", ScaleBox, {Legend Model( 7, Properties( 0, {gradient( {Scale Type( "Quantile" )} )}, Item ID( "Defects", 1 ) ) )} )
)
);
You will see two report windows, Hierarchical clustering and GB.
GB is wafer map of Cluster=6.
Customer understands that by convention, the origin for an image is at the top left and rows are incremented towards the bottom of the image.
But the customer thinks it is in the case of wafers, etc., it could lead to a misjudgment. So the customer request to have this documented in the JMP manual.
Also, the customer understands that the wafer map can be flipped but the option is not documented either and wants it to be documented.
What would the value be to you and/or other users if this new feature is provided?
Decrease the risk of misjudgement of wafer map.
Is this an external customer request?
Yes.
