Abstract
A semiconductor die is electrically connected to the leads of a flagless lead frame and is fully encapsulated by encapsulant to form a semiconductor package. A method of manufacturing the semiconductor package entails encapsulating a flagless lead frame with a first encapsulant such that a top surface of the leads of the flagless lead frame are exposed from the first encapsulant. A semiconductor die is mounted directly to the first encapsulant located in a central region of the lead frame. Electrically conductive interconnects are formed between die pads on the semiconductor die and the top surface of respective leads of the lead frame. The semiconductor die, conductive interconnects, and top surface of the leads is encapsulated with a second encapsulant so that the semiconductor die is sandwiched between the first and second encapsulants, thus isolating the semiconductor die from package stresses.
