Integrated circuit (IC) die attached between an offset lead frame die-attach pad and a discrete die-attach pad
Abstract:
An integrated circuit (IC) package, e.g., a power MOSFET package, may include a lead frame including (a) a main lead frame structure including a plurality of leads and defining or lying in a main lead frame plane, and (b) an offset lead frame die-attach pad (DAP) defining or lying in an offset plane that is offset from the main lead frame plane. The power IC package may further include a semiconductor die having a first side attached to the offset lead frame DAP, and a conductive element attached to both (a) a second side of the semiconductor die and (b) the main lead frame structure. The lead frame including the offset DAP may emulate the functionality of a copper clip, thus eliminating the need for the copper clip. The power IC package may also exhibit enhanced heat dissipation capabilities.
