Semiconductor technical question

I'm working on a new patent case that is requiring me to quickly educate myself on the physics of semiconductor devices. Could someone help with what I think is a basic question?

I'm seeing references to both "N type diffusion" and "N+ type diffusion." I understand the difference between a P type diffusion and an N type diffusion, but N+ is a new term to me in this context. What does it mean? Any help is appreciated. Thanks. --Bob

Maybe it's the difference between nekkid and a nekkid hamster.

IANA expert, but I believe that an "n+ semiconductor is one that is more heavily doped than the standard n type; the same applies to p and p+ semiconductors.
