Scotts Valley, CA June 25, 2021 – ALP recently published an interesting set of profiles on very highly doped SiP materials at the 20th International Workshop on Junction Technology (IWJT2021) conference.
ALP’s Differential Hall Effect Metrology (DHEM) provides sub-nm resolution resistivity, mobility and, carrier profiles of semiconductors. In addition to details on near-surface resistivity and carrier profiles, this paper discussed the impact of very high doping levels on carrier mobility profiles in this material system. The degradation of mobility can be quantified as a function of depth and can be correlated to the the dopant levels as provided by SIMS.
