Highlight on wafer map

[#1]

Hi,

Is there a way to select the region on the wafer map like a wedge shape (yellow region in the snippet) across the 4th quadrant of the circle between 4'o clock to 5'o clock?

I am aware of doing lasso selection but I am wondering if I can do a more symmetric selection using formula or jsl way?

 Thanks,

Sure. You could create a formula those slices and use data filter with "select" enabled on that formula column to perform the selections.

@jthi I was thinking the same but I am not sure how to derive the formula

[#4]

Neither do I because I don't know what you wish to select. There seems to be some angle, inner circle, some width and maybe some weird shape inside the red area (could be that everything just isn't colored).

@jthi  I am thinking to create a wedge shape with size X = 8 dies and Y = 16 dies between 4'o clock to 5'o clock with 45 deg angle

[#6]

Do you want a wedge shape or rectangle? Could you properly draw it and mark the "measures" you have?

[#7]

Either one is fine. I have roughly highlighted the region. Die size doesn't matter as long as the shape is a rectangle 

[#8]

I went a bit wrong way with the rectangle (your shape isn't rectangle) so this doesn't overlay that well with it (I also guessed the corner points).

So I found other function and modified that for JMP. It is closer but it is still using hard-coded corner points

@jthi  This looks good Jarmo. Can you share the table with formula?

The solution might be easier in polar coordinates. Create two new data columns with the radius and angle for each data point. Plot the data using the new coordinates and see if the target rows are easier to identify with a lower and upper bound on the radius and angle.  You can interactively try different selection criteria using a data filter. The selected rows would define the targets in the original Cartesian coordinates of the wafer map.
