Embedded Computing: May 2005 Archives
TIPPINST - Following on from a comment left by John McCormac who recommended that I look a the work done by Markus Kuhn into Tamper resistant smart card processors I came across an article that describes the process.
Ingredients
Hot Fuming Nitric acid
acetone in an ultrasonic bath
deionised water
isopropanol
Hydrofluoric acid (Very dangerous)
Hardware required
confocal Microscope with a CCD camera
The article describes the process in detail as well as photo and resulting images.

TIPPINST - While researching something else I came across this article which has been taken from the July 1977 edition of Television Magasine. Bernie Goldbach and Mathew Mather should be able to relate this as it has resonances with a conversation I had earlier with Bernie today.
The project uses the MM-57105 game chip from National Semiconductor and circuit diagrams etc are included.

TIPPINST - I have thrown this question out to a few of my colleagues here at TI. A cursory search on the internet does not reveal any answers. As part of our research it would be nice to have a look under the hood so as to confirm some empirical figures. We believe that there is the risk of chemicals etc but we are not yet sure is it practical or not. If any one has had any experience with this please contact me at.
