  • Publication number: 20240093357
    Abstract: A semiconductor device is manufactured by modifying an electromagnetic field within a deposition chamber. In embodiments in which the deposition process is a sputtering process, the electromagnetic field may be modified by adjusting a distance between a first coil and a mounting platform. In other embodiments, the electromagnetic field may be adjusted by applying or removing power from additional coils that are also present.

  • Publication number: 20080272390
    Abstract: An LED apparatus comprises a base, an LED device, an electrode member and an insulation layer. The base has a bevel side to be embedded with a corresponding receiving base for electrical conduction of an electrode (e.g., a negative electrode). The LED device is placed on an upper surface of the base. The electrode member comprising a metal rod and an electrode plate is connected to the LED device for electrical conduction of an electrode (e.g., a positive electrode). The insulation layer is placed between the electrode plate of the electrode member and the base for electrical insulation. The bevel side of the base can be modified as desired, and is generally less than 10 degrees, and preferably less than 5 degrees, and may be less than 3 degrees if needed.

  • Publication number: 20080174247
    Abstract: A high-power LED lamp comprises a cuplike lamp housing, an LED device, an adapter and a circuit board. The inner surface of the cuplike lamp housing is a reflective curved surface for reflecting the light from the LED device disposed at the bottom the cuplike lamp housing, so as to improve the lighting efficiency. The position of the LED device has the relation: 0.05<HL/HT<0.35, where HT is the total depth of the cuplike lamp housing, HL is the distance between a surface of the LED device and the bottom of the cuplike lamp housing. The adapter is configured to secure the LED device, and the circuit board is configured to provide power source to the LED device. The LED device is a stack structure comprising an LED package device, a ring member, an electrode plate and an insulation glue layer.

  • Patent number: 6974543
    Abstract: A magnetic-energy-releasing molecular rearranging structure includes an amount of magnetic powder, which is molded into a magnetic member in the form of a ball, a mass, or a flat piece, and having magnetic-energy-releasing molecules, so that the member has magnetic lines that together with earth poles produce a radiated magnetic field. Superficial molecules of a solid body and a liquid, or air molecules in a limited space may be magnetized and rearranged using the magnetic-energy-releasing member, and molecules of a substance that is to be magnetized may be magnetized and rearranged through magnetic energy transmission from the magnetized molecules of the solid body, the liquid, or the air in the limited space to the substance.
