Have you ever wanted to take a bunch of photos of an integrated circuit die and combine them into a high-res image? The stitching software can be difficult, so I've written a guide to the process I use. These tips may also be useful for other Hugin panoramas.
The first step is to take a bunch of photos of the die with a microscope.
I used an old Motorola 6820 PIA (Peripheral Interface Adapter) chip. This chip had a metal cap over the die that popped off easily with a chisel, exposing the die. The 6820 is notable as the keyboard interface chip in the Apple I computer.
Thanks for your excellent post. You mentioned AmScope microscope.

I am also thinking about buying a good (metalurgical) miscroscope.
Not sure yet how metalurgical microscope works but I would need a good microscope to check digitizers/touch of touch mobiles. We repair mobiles and sometimes a digitizer stops working and we would need to check ( wire) traces in the digitizer.
Would you recommend that kind of microscope for that task?
I'm no expert on this, but I think you'd want a lower-power binocular microscope rather than a metallurgical microscope for checking wire traces, something like this one.

Thank you for your reply.
The lower-power binocular microscope seems to have a low magnification.( we already have one). As far as I know a metallurgical microscope is a kind of microscopes that have fairly high magnification and for that reason I was thinking about a metallurgical microscope.
Can you please explain when a metallurgical scope is/not useful ?

Yes, I need high magnification yet
I am not still sure if it is possible to use a metallurgical microscope for a touch screen( also called a digitizer) that is transparent.
What do you think?
Thank you for

The microscope you used has 40X-2000X Magnification.What magnification did you use for those
pictures you posted in this topic?
I was thinking about buying a metallurgical microscope for some time already but the price is still rather high and not sure if it works for our needs.
Would you mind taking a few pictures of a touch/digitizer of a mobile phone with your AmScope metallurgical microscope? (I can not imagine how a metallurgical scope displays a digitizer of mobile phone.)
Thank you very much again for your time and help

It seems the metallurgical microscope to be useful for me too.
And what magnification did you use for that picture of the Screen pixels?
The microscope from Amazon( you provided a link) has 40X-2000X Magnification. But you use mostly 100x.
When can be useful to have a such large 2000x magnification?
(I am asking to choose the best microscope ( for me) regarding magnification/price.)
Thank you again for help.
