Adds a diffusion doping region to the simulation environment. This command requires a CHARGE solver region to be present in the objects tree.
Supported Product: DEVICE
Add a diffusion doping region in the simulation environment.
This function does not return any data.
The following script command will add a n-type diffusion doping object and set its properties. The face where the dopants are introduced is defined by the "source face" property and the peak doping is defined by the "concentration" property. The "junction width" property defines the distance over which the doping drops from the (peak) concentration to the low "ref concentration" at the other faces of the doping object.
# set dimension
# set doping profile
set("source face",6); # 1 = lower x, 2 = upper x, 3 = lower y, 4 = upper y, 5 = lower z, 6 = upper z
set("concentration",1e25); # SI unit (/m3)
The figure below shows the resulting doping profile.
