  • Patent number: 8802550
    Abstract: First flash irradiation from flash lamps is performed on an upper surface of a semiconductor wafer supported on a temperature equalizing ring of a holder to cause the semiconductor wafer to jump up from the temperature equalizing ring into midair. While the semiconductor wafer is in midair above the temperature equalizing ring, second flash irradiation from the flash lamps is performed on the upper surface of the semiconductor wafer to increase the temperature of the upper surface of the semiconductor wafer to a treatment temperature. Cracking in the semiconductor wafer is prevented because the second flash irradiation is performed while the semiconductor wafer is in midair and subject to no restraints.

  • Patent number: 8383513
    Abstract: Rapid thermal annealing methods and systems for annealing patterned substrates with minimal pattern effect on substrate temperature non-uniformity are provided. The rapid thermal annealing system includes a front-side heating source and a backside heating source. The backside heating source of the rapid thermal annealing system supplies a dominant amount of heat to bring the substrate temperature to the peak annealing temperature. The front-side heating source contributes to heat up the environment near the front-side of the substrate to a temperature lower than about 100° C. to about 200° C. less than the peak annealing temperature. The asymmetric front-side and backside heating for rapid thermal annealing reduce or eliminate pattern effect and improve WIW and WID device performance uniformity.

  • Patent number: 8222087
    Abstract: Magnetic recording heads and associated fabrication methods are disclosed. A heat spreader structure in a magnetic recording head includes a seed layer with a heat spreader layer formed on the seed layer. When the heat spreader layer (e.g., Aluminum Nitride) is grown on the seed layer (e.g., NiTa or Alumina), the heat spreader layer forms a well-oriented crystalline structure that allows for a desired thermal conductivity, such as a thermal conductivity greater than about 55 W/m?K. As a result of using the seed layer, a material such as Aluminum Nitride can be used for a heat spreader layer to effectively dissipate heat in a magnetic recording head.

  • Patent number: 7452800
    Abstract: A bonding technique suitable for bonding a non-metal body, such as a silicon MEMS sensor, to a metal surface, such a steel mechanical component is rapid enough to be compatible with typical manufacturing processes, and avoids any detrimental change in material properties of the metal surface arising from the bonding process. The bonding technique has many possible applications, including bonding of MEMS strain sensors to metal mechanical components. The inventive bonding technique uses inductive heating of a heat-activated bonding agent disposed between metal and non-metal objects to quickly and effectively bond the two without changing their material properties. Representative tests of silicon to steel bonding using this technique have demonstrated excellent bond strength without changing the steel's material properties.
