<br>
I am working on providing phosphorous doping capability at a tube furnace that will be used for fabrication classes (the first class will make a solar cell).<br>
<br>
My research to date uncovered POCl3 and solid sources as possible methods for P diffusion. As expected, each seems to come with benefits and drawbacks.<br>
<br>
I am hoping that you are willing to share your experience/advcie with me and/or the group so I can make a quick and smart decision.<br>
<br>
Thank you very much,<br>
