| I got a lot of requests to image stuff, so here's my official policy. | 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. | In terms of consumables, equipment wear etc, each simple chip costs me about $20 to decap/image (not counting huge equipment NRE).

| 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). | Most of this is targeted towards small chips up to the mid 90's.

| | Other: most of the work is in decapping, not actual imaging. If you happen to already have a bare die and would be satisfied with a quick / lower quality scan, feel free to send me a few dies. This may actually work out well for you since most of the money is in the microscope, not the decapping supplies. |
