Doping is the process of adding impurities to silicon wafers in a controlled manner to alter the electrical properties of the semiconductor. [Zach]’s doping method is a more localized version of ...

The proposed process utilizes aluminum (Al) doped and induced polycrystalline silicon (poly-Si ... The researchers built the contacts by using p-Si wafers and p-Si substrates, on which they ...

Today we're doping silicon wafers with a phosphoric acid and a fiber laser. ==== Timeline ==== 0:00 Intro 0:39 I have no idea what I'm doing 1:09 Doping silicon 2:21 Thermal diffusion 3:19 Ion ...

For example, doping silicon with phosphorus or boron during melting produces single-crystal silicon wafers with different conductivity types and levels. The ability to precisely dope p- and n-type ...
