This wafer is doped with donor atoms, such as phosphorus for an n-type wafer, or acceptor atoms, such as boron for a p-type wafer. Our discussion centers around a p-type wafer (the most common substrate used in CMOS IC processing).

WebDec 6, 2024 · However, there are still many challenges, including (1) realization of large wafer-scale deposition, (2) a controllable p-type doping method for TMD films, (3) reducing Schottky barrier-induced Fermi level pinning at the metal/TMDs contacts, and (4) high-quality high-k/TMD interface. Weba. Poor fill factor (~72-74%) of crystalline silicon solar cell with n-type silicon as starting wafer compared to solar cell fabricated using p-type wafer. The poor fill factor is mainly due to a low line resistance of the Ag/Al paste and can be partly improved by Ag-plating i.e the metallization of front side still has to be optimized.
