Abstract
A method for thinning a semiconductor die includes providing the semiconductor die having electrical contacts electrically connected to and protruding from a top surface of the semiconductor die. The electrical contacts are spaced from one another on the top surface of the semiconductor die. The electrical contacts are encapsulated and a portion of the top surface of the semiconductor die is covered by a semisolid filler. The semisolid filler fills the space between the electrical contacts. An adhesive layer is applied to a top surface of the semisolid filler, and a backgrinding process is performed on a bottom surface of the semiconductor die. The method allows for thin semiconductor dies to be manufactured while reducing the risk of manufacturing defects associated with backgrinding.
