A 2N2222 die image
I was curious to know what a transistor die looked like so I hacked the can off a 2N2222 and up it under my recently acquired microscope. The die image is above, I’m not sure if I cracked it opening the can or blew it up (it was suspect anyway). Interesting to note that it only has 2 wirebonds. I assume this means that the base is connected directly to the substrate which is P type material?
