BOND FOOT SEALING FOR CHIP FRONTSIDE METALLIZATION
A semiconductor die is disclosed. The semiconductor die includes a semiconductor body, a metallization over part of the semiconductor body and including a noble metal at a top surface of the metallization, a bondwire having a foot bonded to the top surface of the metallization, and a sealing material covering the foot of the bondwire, the top surface of the metallization, and one or more areas outside the top surface of the metallization where oxide and/or hydroxide-groups would be present if exposed to air. The sealing material adheres to the foot of the bondwire and the one or more areas outside the top surface of the metallization where the oxide and/or hydroxide-groups would be present if exposed to air.
LIGHT-EMITTING DEVICE
A light-emitting device comprises a semiconductor stack comprising a first semiconductor layer and a second semiconductor layer, wherein in a top view, the semiconductor stack comprises an outer peripheral region and an inner region, the outer peripheral region exposes the first semiconductor layer, and the second semiconductor layer is disposed in the inner region; an outer insulated structure comprising an insulation layer and a protective layer, the insulation layer comprising a plurality of first insulation layer outer openings and a second insulation layer opening; a first electrode covering the plurality of first insulation layer outer openings; and a second electrode covering the second insulation layer opening, wherein the outer insulated structure comprises a total thickness gradually decreasing from the outer peripheral region to the inner region.
Bonded assembly containing oxidation barriers, hybrid bonding, or air gap, and methods of forming the same
At least one polymer material may be employed to facilitate bonding between the semiconductor dies. Plasma treatment, formation of a blended polymer, or formation of polymer hairs may be employed to enhance bonding. Alternatively, air gaps can be formed by subsequently removing the polymer material to reduce capacitive coupling between adjacent bonding pads.

LIQUID METAL THERMAL INTERFACE
Liquid metal thermal interface materials and their uses in electronics assembly are described. In one implementation, a semiconductor assembly includes: a semiconductor die; a heat exchanger; and a thermal interface material (TIM) alloy bonding the semiconductor die to the heat exchanger without using a separate metallization layer on a surface of the semiconductor die or a surface of the heat exchanger. The TIM alloy may be formed by placing a TIM material between the semiconductor die and the heat exchanger, the TIM material comprising a first liquid metal foam in touching relation with the surface of the semiconductor die, a second liquid metal foam in touching relation with the surface of the heat exchanger.
SEMICONDUCTOR DEVICE
A semiconductor device has a resistance element including a metal block, a resin layer disposed on the metal block, and a resistance film disposed on the resin layer and an insulated circuit board including an insulating plate and a circuit pattern disposed on the insulating plate and having a bonding area on a front surface thereof to which a back surface of the metal block of the resistance element is bonded. The area of the circuit pattern is larger in plan view than that of a front surface of the resistance element. The metal block has a thickness greater than that of the circuit pattern in a direction orthogonal to the back surface of the metal block. As a result, the metal block properly conducts heat generated by the resistance film of the resistance element to the circuit pattern.
