WebAug 17, 1998 · ABSTRACT Rapid thermal diffusion (RTD) of phosphorus has been investigated using a spin‐on dopant (SOD) deposited on a silicon wafer and placed as a dopant source in proximity to a processed Si wafer. In such a process, the efficiency of doping is affected by the amount of P supplied from the SOD to the processed wafer. WebPhosphorus and arsenic are used most commonly to dope silicon.. In practical applications, it is the ability to control conductivity through doping that defines a semiconductor. Some of the materials which are among the best insulators when in pure form, such as diamond, are being used in semiconductor applications through doping. WebThe doping concentration decreases monotonically from the surface, and the in-depth distribution of the dopant is ...
