Semiconductor CSV files adding wafer run order

Hi

A lot of semiconductor equipment produces .csv files for data recorded during processing: a processed batch number containing 1 to X silicon wafers,

The tool will run same process steps repeating on up to X wafers. CSV file shows processed steps repeating but no assignment of the wafer run order. So if we have mutiple csv files imported to JMP then want a formula in the column to auto assign wafer run order; wafer run order will not always be same number of wafers that will vary...

Ideally a formula would be useful.....so we have batch number and process steps in CSV file.

Anyone done this...?.

BATCH NUMBER WAFER RUN ORDER PROCESS STEPS

Could you provide small example of data to see what type of replicates there can possibly be (if there are none, simple Col Rank( ) might be enough or Col Cumulative Sum(1, )

If it would be possible to attach a sample of the excel file it would be very helpful in understanding your problem.

So attached a file where ive manually added wafer run order

Re: Semiconductor CSV files adding wafer run order

One option could be something like this

Col Cumulative Sum(:Process Step == 1, :Batch Number)

but it does make some assumptions such as that your data is always in specific order and that new run order starts when Process Step changes to 1.
