concwentration in p+

Hi friends,

I'm now studying a course related to semiconductor device.
As far as I know, the doping concentration of:

P+ = 10^18 / cm3
P = 10^15 / cm3

How about P- ?? Any information about the doping concentration of P- ??

Is the doping concentration of P- less than that of P ?

Thank for your comment in advance.

Will
 

yes P- means lightly doped but i dont have an estimate number
 

Usually when people say P-, it is around 10^13 or 14
 

Hello !!
How I was studing!!!

The lower concentrations donor and acceptor doping exist in intrinsic semiconductor
10e13 - 10e15 1/cm2 - P- Is the doping concentration in the semiconductor wafer
10e15 - 10e17 1/cm2 - P Is the doping concentration in the wall area
10e19 - 10e21 1/cm2 - P+ Is the doping concentration in the source-drain area
P.S
The doping concentration in the source-drain area is defined the limiting solubility in the silicon of doping element
For B (Boron) it is ~10e19
For P (Phosphorus) it is ~10e20
For As (Arsenic) it is ~10e21
