Equipment I'd like
I got a lot of requests to image stuff, so here's my official policy.
In short, I focus on chips that are of interest to me. I do lots of chips for others, but I give priority to people that are able to provide funds.
In terms of consumables, equipment wear etc, each simple chip costs me about $20 to decap/image (not counting huge equipment NRE). As of 2014, a professional shop charges around $100 for a simple, low resolution top metal dceap/image. People give me upwards of $150 per simple chip if they are feeling generous and want to support other projects. Simple ⇒ not implant ROM and preferably does not require delayering. Not sure what a shop would charge for delayering, but lets say upwards of $100 donation for delayering. Chips from the 80's should be simple.
Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). Similar issues with staining and lapping. Lapping is currently extremely labor intensive and not very well refined (although I can get a small area easily).
This is a hobby and I'm not interested in operating as a business. I'd really like to focus on chips that I can (eventually) release on pr0n, ideally under CC licenses.
In general I want to focus on R&D / labwork and not hand digitization. I do have some limited semi-automatic digitization capabilities for planarized chips though that I'd like to develop (ex: works on PS1 chipset).
Most of this is targeted towards small chips up to the mid 90's. If the die is obnoxiously large (ex: 486 CPU) it will be difficult for me to photograph and stitch the entire thing. Similarly I unfortunately do not have EM capabilities to image fine processes. 180 nm is doable on my equipment but really pushing it (ex: XC2C32A).
Please provide the following information for each chip:
