Long Throw Evaporation

Long Throw Evaporation optimizes the thermal evaporation of indium and other materials for solder bump structures using "lift-off" vacuum deposition. Long throw layout and evaporation sources have capability which provides high volume anisotropic evaporant flux with the uniformity and directionality to cover and fill high aspect ratio features patterned on substrates. High quality vacuum and substrate temperature control add to film quality for high-yield applications.
