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.

Web(see figure 1.2). Impurity atoms utilized as dopants such as boron (B), phosphorus (P) and arsenic (As) occupy substitutional positions where the dopant atoms can contribute free elec-trons or holes to the silicon lattice (dopant atoms introduced to silicon by ion implantation may not occupy substitutional positions until the dopant is activated). WebFor phosphorus-doped silicon, the results of this work differed by 5 % to 15 % from the then commonly used curve. For boron-doped silicon the results differed significantly from the p-type curve in use at the time. A maximum deviation of 45 % occurred at a boron density of 5 1017 cm–3. Because of
