Microalloy

For microalloys the boundary can be treated as a thin layer of the segregating element including segregating impurities. In the case of nanoalloys, the segregation pattern can involve a significant part of the whole grain.

Today, the use of niobium as a microalloy is estimated to account for about 95% of production.

The purpose of this step is to microalloy the aluminum and gold metallizations into the silicon to insure the lowest possible contact resistance […]
