A lead frame used to assemble a semiconductor device, such as a smart card, has a first major surface including exposed leads and a second major surface including a die receiving area and one or more connection pads surrounding the die receiving area. The connection pads enable electrical connection of an Integrated Circuit (IC) die to the exposed leads. A molding tape sized and shaped like the lead frame is adhered to and covers the second major surface of the lead frame. The molding tape has a die receiving area cut-out that exposes the die receiving area and the connection pads on the second major surface of the lead frame and forms a cavity for receiving an encapsulant. The cut-out has an elevated sidewall for retaining the encapsulant within the cavity.
A method of assembling a smart card, comprising:
A method of encapsulating an integrated circuit (IC) die, the method comprising:
