  • Patent number: 11043458
    Abstract: A method of manufacturing an electronic device. For example and without limitation, various aspects of the present disclosure provide a method of manufacturing an electronic device that comprises a die comprising a circuit side and a second die side opposite the circuit side, a through hole in the die that extends between the second side of the die and the circuit side of the die, an insulating layer coupled to the inner wall of the through hole, a through electrode inside of the insulating layer, a dielectric layer coupled to the second side of the die, and a conductive pad coupled to the through electrode. The through electrode and the insulating layer may, for example, extend substantially the same distance from the second side of the die.

  • Patent number: 9431323
    Abstract: To form a semiconductor device, a through electrode is formed in a semiconductor die, and a dielectric layer is then formed to cover the through electrode. The dielectric layer has an opening by being partially etched to allow the through electrode to protrude to the outside, or has a thickness thinner overall so as to allow the through electrode to protrude to the outside. Subsequently, a conductive pad is formed on the through electrode protruding to the outside through the dielectric layer by using an electroless plating method.

  • Patent number: 8900995
    Abstract: A semiconductor device and a manufacturing method thereof are provided. In one embodiment of the manufacturing method of the semiconductor device, a through electrode is formed on a semiconductor die, and a dielectric layer such as a photopolymer is coated on the through electrode to cover the through electrode. Under exposure is performed on the dielectric layer, thereby partially removing the dielectric layer by development. As a result, a top end of the through electrode is exposed to the outside or protrudes through the dielectric layer. The dielectric layer remaining on the top end of the through electrode may be removed by performing a plasma descum process, if needed.
