What is the difference between a PTUB and a P-well?
I've looked in my books and googled it, but I haven't found an answer to my question.
I haven't used nor seen the term PTUB before today, and from what I've seen so far in my search for an answer, the two terms (PTUB and P-well) appear to mean the same thing.
Can anyone point me to a source that describes the difference, or explain the difference between PTUB and P-well? (If there is a difference?)
