wafer map

[#1]

I  want to konw how to make wafer map with JMP.

[#2]

Use the X-Y plot

[#3]

I have put some old code at:

https://community.jmp.com/docs/DOC-7137

that may be worth a look. There are many alternatives, particularly if you are prepared to use JSL.

I think the answer depends on what type of wafer map you're looking for.  The script that Ian@JMP linked seems to be a good option for parametric wafer maps.

If you're looking to build a bin classification wafer map, then the built-in platform that I've found to be most useful is Bubble Plot.  A few tips when using Bubble Plot to make wafer maps:

• Change shape to square for a more "die-like" appearance
• Use Column Properties to set standard properties:
  • X/Y orientation with Value Ordering
  • Bin Colors with Value Colors
• Label is whatever classification you want to show, such as a bin number

I've also managed to create some interesting - what I've termed - Hyper-heat maps.  By creating custom maps to represent sub-die structures, you can then use Graph Builder to make X-Y arranged wafer maps of these heat maps, i.e. a hyper-heat map.  For complex SOCs, this can be a powerful visualization technique.

And, as always, nearly anything is possible using custom-built JSL scripts.

For Bin maps : X/Y plot with Graph Builder. Using wafer id and the wrap function, all wafers from a lot can be displayed together.

For parametric maps : Graph Builder (same as above); Contour Plot.

Hi Murphy,

Do you have an example code of what you mention ?

Thanks

I normally use Graph Builder to do this.

It really depends on what type of data you looking for. For example, i often use this to check my Wafer testing (Chip Probe , SORT) hard bin results.

1. Put X-Loc to X-axis

2. Put Y-Loc to Y-axis

3. Put the Hardbin to Overlay

And you can see the whole wafer by its hardbin.

You can simply use graph builder to make wafer maps.

use N View Levels( 4 ),First View Level( 1 ) to arrange in columns and rows

then append all views one by one.

N View Levels( 4 ),First View Level( 2 )
