A relatively thin wetting promoting layer of copper, for example, is provided on the metallic barrier layer to promote uniform wetting of a solder, such as a lead-free, zinc-based solder, onto the lead frame during a die connect process by which a chip is connected to the lead frame. A copper/zinc intermetallic layer is formed during the flow and solidification of the solder. Substantially all of the copper in the copper layer is consumed during formation of the copper/zinc intermetallic layer, and the intermetallic layer is sufficiently thin to resist internal cracking failure during manufacture and subsequent use of the electronics packaging arrangement.

Packaging solutions for devices and systems comprising lateral GaN power transistors

Номер: US9824949B2
Принадлежит: GaN Systems Inc

Packaging solutions for devices and systems comprising lateral GaN power transistors are disclosed, including components of a packaging assembly, a semiconductor device structure, and a method of fabrication thereof. In the packaging assembly, a GaN die, comprising one or more lateral GaN power transistors, is sandwiched between first and second leadframe layers, and interconnected using low inductance interconnections, without wirebonding. For thermal dissipation, the dual leadframe package assembly can be configured for either front-side or back-side cooling. Preferred embodiments facilitate alignment and registration of high current/low inductance interconnects for lateral GaN devices, in which contact areas or pads for source, drain and gate contacts are provided on the front-side of the GaN die. By eliminating wirebonding, and using low inductance interconnections with high electrical and thermal conductivity, PQFN technology can be adapted for packaging GaN die comprising one or more lateral GaN power transistors.
