Abstract:
A device is disclosed which includes, in one illustrative example, an integrated circuit die having an active surface and a molded body extending around a perimeter of the die, the molded body having lips that are positioned above a portion of the active surface of the die. Another illustrative example includes an integrated circuit die having an active surface, a molded body extending around a perimeter of the die and a CTE buffer material formed around at least a portion of the perimeter of the die adjacent the active surface of the die, wherein the CTE buffer material is positioned between a portion of the die and a portion of the molded body and wherein the CTE buffer material has a coefficient of thermal expansion that is intermediate a coefficient of thermal expansion for the die and a coefficient of thermal expansion for the molded body.
