Witryna27 lip 2024 · Herein, the gettering strength of a range of phosphorus- or boron-doped polysilicon films from different fabrication techniques is assessed and compared. Iron, one of the most common metallic impurities in silicon, is used as a tracer impurity to quantify the gettering strength (segregation coefficient). WitrynaTherefore, impurity gettering has been widely studied to reduce their deleterious effect. Several methods have been investigated, including spontaneously occurring and intentionally formed sinks for the transition metals—at the surface and bulk. Depending on where we capture metal impurities, it is classified to intrinsic and extrinsic gettering.
