Impurity gettering
WitrynaA method of manufacturing a semiconductor device on a silicon-on-insulator wafer including a silicon active layer having at least two die pads formed thereon, the at least two die pads separated by at least one scribe lane, including the steps of forming at least one cavity through the silicon active layer in the at least one scribe lane; forming at … WitrynaImpurity Gettering T.Y. Tan, in Encyclopedia of Materials: Science and Technology, 2001 1 Gettering Requirement and Methods Gettering consists of the creation of suitable gettering sites and the gettering processes of contaminants. Both of these aspects will be discussed.

WitrynaImpurity gettering in silicon is an indispensable technology to avoid device degradation by heavy metal contamination. Thin polycrystalline films deposited on the backside of silicon wafer, in other words polysilicon back seal (PBS) is one of the frequent external gettering (EG) techniques. Witryna1 cze 2024 · Given the prominent role that impurity gettering has played in the development of silicon PV technology, and the potential for doped polysilicon/oxide contacts to replace P- and B-doped silicon layers for junction formation purpose, their potential impurity gettering effects need to be investigated and understood.
