Is it posible to open a chip and view it?

Hello,

I have some old analog ICs and a 6502 processor, and I'm curious if anyone tried to open a DIP package, expose the silicon chip and analyze it with a microscope. It's interesting to view simple analog and MSI, LSI chips, with reasonable large structures.

So, if you know a method or site about this, please post.

Thanks

We left the chips for hours on a bath of that liquid .And the plastic disolved easly .So is possble .you have now to find what solvent to use .I could not help you!

Thanks for the reply.

I found a few details about chemicals here:

but the process seems quite complex, chemicals are highly toxic.
