NMOS layers vs Jeri JeriEllsworth Homebrew NMOS Transistor

I just watched Jeri JeriEllsworth's video on Homebrew NMOS Transistor Step by Step

How .. if at all, do the layers she describes correspond to the layers on the visual6502 simulation ?

--------------- Jeri's Video :


- etch gate area



4 - intermediate oxide layer & drive In (oxide layer covers source & drain regsions)

- etch phosporosilica from drain, source



3 - phosporosilica film (predeposition) high concentration of phosporus into wafer

- etch source and drain (active layer) (back down to p-type)



2 = 5,000 angstrom oxide
1- p type wafer

-------------------



Simulator :



diffusion grounded diffusion powered diffusion polysilicon metal protection
