-====== Honeywell ======+====== Foundry ID (FIXME: clean up) ====== 
 + 
 +Device vendors concerned about reverse engineering often use simple tricks to make it harder to put a BOM together. One of these is to remove the labeling from, or even re-label with a laser engraver, various ICs on the board. Re-labeling can also be done for brand reasons. 
 + 
 +The first step in identifying an unknown components is to determine the vendor. If there's no logo on the die this can be difficult, but fab processes vary enough from vendor to vendor that some hints can be gained just by looking at the die structure. 
 + 
 +This page is a library of specific process examples, not a place to discuss general fabrication techniques. General fab topics belong on the [[siliconprawn>process_tech|process technology]] page. 
 + 
 +====== CMP fill ====== 
 + 
 +Although only present on smaller (<=350nm typically) process technology, CMP fill patterns are distinctive enough that a pretty good guess of the vendor can sometimes be obtained from the fill pattern alone. 
 + 
 +All images shown are top metal with overglass intact, unless otherwise labeled. 
 + 
 +Please try to include scale bars in all images.

I (azonenberg) was imaging some MEMS prototypes on a Zeiss Supra 55 in the RPI cleanroom for a customer and decided to buy an extra hour of scope time out of my own pocket while I was in the lab.
