Difference between p- and p+ substrate

I hope someone can give me some information about difference between Nwell and n+, p- and p+

all are silicon in a typical silicon wafer.
the differences are the doping levels, polarities, and concentrations.
p- and p+ are both positively charged, why the p+ is more heavily doped.
Mos IC design books go over the processing of the silicon in the first chapter of the book.
typically the deeper into the silicon, the less doping there is and the more resistive the material becomes.
