  • Patent number: 6476478
    Abstract: A semiconductor chip package and a method of making the package are disclosed. The method includes forming a lead frame having a die pad and leads. At least one of the leads has a tab projecting upward and laterally from a body of the lead. In one embodiment, curved tips are formed on the inner ends of the leads. At least a portion of the lead frame is encapsulated with a mold material to form a package mold having a cavity. The cavity has a floor with a thickness substantially similar to the thickness of the leads so as to expose upper surfaces of the inner ends of the leads. The leads have lower surfaces exposed at the lower surface of the package mold. The lead tab is entirely encapsulated within the package mold. A semiconductor die is mounted on the lead frame subsequent to the encapsulation of at least a portion of the lead frame. The semiconductor die is enclosed in the package mold by placing a covering such as a lid over the semiconductor die.
