thermomigration

[¦thər·mō·mī′grā·shən]
(electronics)
A technique for doping semiconductors in which exact amounts of known impurities are made to migrate from the cool side of a wafer of pure semiconductor material to the hotter side when the wafer is heated in an oven.

Its low yellowing properties ensure no influence on thermomigration and degree of whiteness even under molding conditions.
Professor Cemal Basaran, the director of the Electronics Packaging Lab in UB's School of Engineering and Applied Sciences, says that the four years of quantum mechanics calculations performed by him and his doctoral student Tarek Ragab have proved that higher current density in carbon nanotubes does not lead to electromigration and thermomigration.
He is credited with transforming the field from the realm of empirical equations to computational simulation-based fatigue life predictions where the thermo-mechanical as well as electromigration and thermomigration loads are all accounted for in a unified manner.
