Teardown of a quartz crystal oscillator and the tiny IC inside

In the "How CMOS logic is implemented" section, the text about the NMOS transistor says the source and drain are "P+ silicon", but the diagram labels them as "n+ diffusion". Is "P+ silicon" somehow the same thing as "n+ diffusion"?

Oops, thanks for pointing that out. It's now fixed.

Thanks! It seemed confusing, but I didn't know enough about the terminology of silicon doping to know if it was correct. I probably should by now, I've been enjoying your teardowns for quite some time!
