Abstract:
An integrated circuit package comprising:a package substrate; an integrated circuit mounted to said package substrate, wherein said integrated circuit includes an outer boundary; an underfill material having an underfill material inner boundary situated between said integrated circuit and said package substrate and substantially spaced apart from a center region of said integrated circuit to define a non-filled spaced between said integrated circuit and said package substrate, and an underfill material outer boundary extending beyond said integrated circuit outer boundary, wherein said underfill material occupies approximately 25% of the space between the integrated circuit and the package substrate, and said non-filled space occupies approximately 75% of the space between the integrated circuit and the package substrate; and, an encapsulant disposed over said integrated circuit and having an encapsulant material and an encapsulant outer boundary that extends beyond said integrated circuit outer boundary wherein said encapsulant material is different from said underfill material.
