Latest Patents

Liu holds a patent for "Leadframe packages having enhanced ground-bond reliability." This patent describes various semiconductor package arrangements and methods that improve the reliability of wire bonding a die to ground or other outside contacts. In one aspect, selected ground pads on the die are wire bonded to a bonding region located on the tie bar portion of the lead frame. The tie bar is connected to an exposed die attach pad that is downset from the bonding region of the tie bar. In some embodiments, the bonding region and the leads are at substantially the same elevation above the die and die attach pad. The die, bonding wires, and at least a portion of the lead frame can be encapsulated with a plastic encapsulant material while leaving a contact surface of the die attach pad exposed to facilitate electrically coupling the die attach pad to an external device.
