| The variable Win now contains the contact information for the plot window. The window will look like:

| | |
| The next set of commands adds the material boundaries.
| |

| |
| }

| |
| | |
| The abouve section of commands duplicates the old style "plot.2d bound" command. The plot window looks:

| This set puts isoconcentration lines on the plot. After [[BLTWindow | changing]] the line style for the various elements, and selecting fill for the oxide and nitride. These options are selected in the [[BLTWindow | BLT plot window]]. The final graph looks like :

| === One-Dimensional Plots ===

| |
| [[BLTplot | CreateLine]] $Win Arsenic [ [[sliceCommand | slice]] silicon y = -2.0]
| |
| | |
| This code section will draw the boron and arsenic concentrations at the left edge of the device. Both lines are on the same plot.

| === Grid Plot ===
| |
| | |
| We create a structure with an interesting grid using the commands:
| |
| | |
|
| |
| Grid2D
| |
| foreach m [mater] {Smooth $m}
| |
| | |
| This smooths each region of the mesh.
| |
| | |
|
| |
| foreach m [ [[materCommand | mater]] ] {
| |
| [[BLTplot | CreateBound]] $Win $m [ [[boundCommand | bound]] $m]
| |
| }
| |
| FlipY $Win 1
| |
| | |
| This code section outlines each section. The grid can be plotted using a combination of the element command and the CreateLine command.
| |
| | |
| foreach m [ [[materCommand | mater]] ] {
| |
| [[BLTplot | CreateBound]] $Win $m [ [[elementCommand | element]] $m]
| |
| }
| |
| | |
| Each material has its grid added to the plot. After some [[BLTWindow | property editing]], the plot looks like:

Contour and Color Plots
A structure is created with the following set of commands:
Grid2D
sel z=1.0e17 name=Boron store
sel z=1.0e15 name=Arsenic store
implant arsenic dose=1.0e15 energy=20
strip photo=az
diffuse time=5 temp=1100 dry
The plot is created with:
plot.2d bound fill
sel z = Boron-Arsenic
contour val = 0.0
sel z = log10(abs(Boron-Arsenic))
for {set i 15} {$i <= 20.0} {incr i} {
contour val = $i
}
This code section will draw the outline of the device and stretch it to fill the plot window. The next line selects the doping concentration and plots a line along the metallurgical junction. Then plot variable is selected to the log base 10 of the absolute doping concentration. A loop from 15 to 20 follows with contour lines being drawn each decade for both p- and n-type doping. The resulting plot:
One-Dimensional Plots
Using the same structure as before, we can perform depth plots through several regions of the device.
sel z=log10(Boron)
plot.1d y=-2.0
sel z=log10(Arsenic)
plot.1d y=-2.0 !cle
This code section will draw the boron and arsenic concentrations at the left edge of the device. Both lines are on the same plot:
