Wafer Maps

I have been drawing wafer maps in Graph Builder using Customize Graph.  One issue I have is that the custom outline I have remains static in the frame, whereas the die can move depending on where they are populated.

 

For example, if I only test a few die, their location appears to relocate to the bottom and left relatively to the drawing.

Aside from adding bogus data to occupy the previous extremities, is there a way to have the relationship remain fixed?  The code contained in the Customize Graph Script is as follows.

Transparency( 0.5 );
Fill Color( "Gray" );
Oval( -1, -1, 7, 7, 1 );
Pen Size( 2 );
Line( [-1, -0.855, -1], [2.75 3 3.25] );
Pen Color( "Black" );
Pen Size( 2 );
Oval( -1, -1, 7, 7 );
Pen Color( "Black" );
Pen Size( 1 );
Line Style( "Dotted" );
Oval( -0.9, -0.9, 6.9, 6.9 );
Transparency( 1 );
Fill Color( "White" );
Polygon( [-1, -0.855, -1], [2.75 3 3.25] );
Line Style( "Solid" );
Pen Color( "Black" );
Fill Color( 1 );
Pen Color( "Black" );
Rect( 1.5, -0.5, 4.5, 0.5 );
Rect( 0.5, 0.5, 5.5, 1.5 );
Rect( 0.5, 1.5, 5.5, 2.5 );
Rect( -0.5, 2.5, 6.5, 3.5 );
Rect( 0.5, 3.5, 5.5, 4.5 );
Rect( 0.5, 4.5, 5.5, 5.5 );
Rect( 1.5, 5.5, 4.5, 6.5 );
Rect( -0.5, 2.5, 0.5, 3.5 );
Rect( 0.5, 0.5, 1.5, 5.5 );
Rect( 1.5, -0.5, 2.5, 6.5 );
Rect( 2.5, -0.5, 3.5, 6.5 );
Rect( 3.5, -0.5, 4.5, 6.5 );
Rect( 4.5, 0.5, 5.5, 5.5 );
Rect( 5.5, 2.5, 4.5, 3.5 );

Automation and ScriptingRe: Wafer Maps

I should probably point out that I treat the x and y coordinates as ordinal variables.  Changing that seems to alter the frame of reference.  I guess my question is, can I keep those as ordinal and still achieve alignment consistency?

 

Re: Wafer Maps

Have you considered using map files? You can check the values which get assigned to each point from axis settings

I think if you are using Ordinal modelling types, you might have to add those "missing" points to your data. Usually this is quite easy to do with a join if you have a mapping table. If I remember correctly there will be a column property in JMP19 which should make this easier.

Re: Wafer Maps

I did this and it works.  Probably a lot better ways out there though.  Makes the columns continuous only while the plot window is open.

Re: Wafer Maps

I think you could also use Transform Columns to create those continuous columns

 

Names Default To Here(1); 

dt = open("$SAMPLE_DATA/Big Class.jmp");

dt << Select Where(:age == 14) << Hide and Exclude(1) << Clear Select;

gb = dt << Graph Builder(
	Transform Column("Transform[age]", Formula(:age)),
	Size(525, 454),
	Show Control Panel(0),
	Variables(X(:"Transform[age]"n), Y(:height)),
	Elements(Points(X, Y, Legend(13)))
);

Write();

Re: Wafer Maps

The problem however with continuous data is the way it references the die.  The actual die number on X is to the left of the die rather than the middle.  On Y the number is to the bottom.  Creates a disclaimer requirement for every communication.

 

 

Re: Wafer Maps

very common problem.

A  setting to shift the axis labels( offset +0.5) could help many users

Re: Wafer Maps

Hi, @SpannerHead 

 

The trick to making this work consistently is to use map shape files. This lets you assign colors based on the XY Die coordinates and makes sure they consistently show up in the same place.   

 

The Semiconductor Toolkit Add-in (formerly here ) will be arriving in the JMP Marketplace in the fall.  It's designed specifically for this kind of data and visualization and will make those shape files for you.  Here's a little preview:

 

 

 

 

Best,

Re: Wafer Maps

Will the new STK provide a workaround for the geodesic axes as-default? 

Re: Wafer Maps

@Luis_HC - Yep - though that's nothing special to the STK - just a feature of the shape files.  Unless there is a coordinate system in the shape file that needs geodesic axes, it shouldn't use them.  

Re: Wafer Maps

Hi @MikeD_Anderson , sure?
Stop assuming geodesic scale based on use of map shapes 

Re: Wafer Maps

@hogi  - yep.  There was a bug where occasionally it would get confused and kick over into Geodesic - but, I haven't run into it in a long time. I've been using shape files with the STK for 10 years now without any consistent issues. I've been testing and working on the new version of the toolkit for 6 months now on JMP 19 and haven't run into the bug once.

Re: Wafer Maps

Ah, just an issue when adding Background Maps : )

Re: Wafer Maps

@MikeD_Anderson ,

 

Solely adding to this post to tell you that that looks awesome! Excited to see it in action

 

Thanks,

Ben

Re: Wafer Maps

I've used STK's Build Shape Files function, Use Die Index if I recall correctly, to generate shape files. When I apply the Background Map produced by the shape file, the axes change to geodesic even though I've set linear scale for the Axis column property in the coordinate system of the shape file and the Axis column property of the data files. 

Re: Wafer Maps

Yep - that's the bug - I'm taking a different approach with the JMP 19 version.  It doesn't have the same problem.  I'm doing all the background maps, etc. programmatically.  Since I haven't run into that in a long time, I'm guessing the issue is either fixed or I'm circumventing it.  

 

Regardless, be sure to report it to tech support as a bug (it's not a feature!) along with the steps to reproduce.
