Abstract: A method for encapsulating a substrate includes placing a hardened encapsulant material in a container. The encapsulant material is then heated and stirred until it is in a liquid or gel state. The liquid encapsulant material is held in the container in a vacuum state and dispensed over semiconductor dies along a guide, which allows the liquid encapsulant material to cool slightly before it covers a die.
