Thin silicon foils with thickness about 3 to 4 μm are prepared by semiconductor process combined with heavy doped self stop etching process.

The LiCoO 2 cathode for molten carbonate fuel cell (MCFC) was doped with Mg by semiconductor doping method, and then was heavy doped with rare earth elements La and Ce.
