  • Patent number: 9852750
    Abstract: An improved method of controlling topographical variations when milling a cross-section of a structure, which can be used to reduce topographical variation on a cross-section of a write-head in order to improve the accuracy of metrology applications. Topographical variation is reduced by using a protective layer that comprises a material having mill rates at higher incidence angles that closely approximate the mill rates of the structure at those higher incidence angles. Topographical variation can be intentionally introduced by using a protective layer that comprises a material having mill rates at higher incidence angles that do not closely approximate the mill rates of the structure at those higher incidence angles.

  • Patent number: 9581526
    Abstract: An improved method and apparatus for S/TEM sample preparation and analysis. Preferred embodiments of the present invention provide improved methods for TEM sample creation, especially for small geometry (<100 nm thick) TEM lamellae. Preferred embodiments of the present invention also provide an in-line process for S/TEM based metrology on objects such as integrated circuits or other structures fabricated on semiconductor wafer by providing methods to partially or fully automate TEM sample creation, to make the process of creating and analyzing TEM samples less labor intensive, and to increase throughput and reproducibility of TEM analysis.

  • Patent number: 7054113
    Abstract: A method for manufacturing a reader/writer is provided having a substrate with an undercoat formed thereon. A first shield is formed over a portion of the undercoat and a pair of reader leads is formed over the first shield and undercoat. A read sensor is formed between the reader leads and a first pole/second shield is formed over the reader leads. A mid coat is formed over the undercoat and the reader leads. A second pole is formed over and in contact with the mid coat. A lead is formed over the second pole. A pedestal is formed over the reader lead and an overcoat is formed over the second pole and the lead and around the pedestal. A pad is then formed over the pedestal.
