The results will be used just for comparison. Thank you !
POCl3 emitter is formed on both side of Si wafer after P-diffusion process. This step yields n+pn+ structure. I would like to know how I can protect the emitter on the front side of wafer, using a...

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
