can anyone provide me with Ptype depletion mode (FET) diagram??

Question

Hi thanks all for ur response ,,, but i should have mentioned that i am not looking for SYMBOLS ,,but block diagrams say something like {since its a ptype i want a block diagram involving """SOURCE & DRAIN CONNECTED WITH IMPLANT IMPURITY............ETC ETC I HAVE THE ONE WITH ENHANCEMENT MODE I JUST NEED TO VERIFY MY DIAGRAM WITH SOMEONE ELSE'S EVEN THOUGH THANKS FOR ALL THE RESPONSE"""""

It's the 5th symbol up from the bottom.

EDIT after you comments:
I don't have a link to a picture, but I can describe it for you.

The substrate is p-type material.
The source and drain terminals are metallization over small wells of heavily doped n+

There is a very thin region of induced n+ material in between the source and drain directly under the gate oxide. This is formed by "grounding" the substrate (or on older devices applying a negative bias voltage), and applying a positive bias to the gate. this region is the depletion region (depleted of holes, and saturated with electrons, so it is conductive).

Now when an external voltage are applied to the gate, it will work 'against' the bias to further enhance or deplete that depletion region of electrons.
