  • Patent number: 8217423
    Abstract: While embedded silicon germanium alloy and silicon carbon alloy provide many useful applications, especially for enhancing the mobility of MOSFETs through stress engineering, formation of alloyed silicide on these surfaces degrades device performance. The present invention provides structures and methods for providing unalloyed silicide on such silicon alloy surfaces placed on semiconductor substrates. This enables the formation of low resistance contacts for both mobility enhanced PFETs with embedded SiGe and mobility enhanced NFETs with embedded Si:C on the same semiconductor substrate. Furthermore, this invention provides methods for thick epitaxial silicon alloy, especially thick epitaxial Si:C alloy, above the level of the gate dielectric to increase the stress on the channel on the transistor devices.

  • Patent number: 8198142
    Abstract: A general purpose BGA security cap includes a substrate, an integrated circuit die, and an array of bond balls. The substrate includes an anti-tamper security mesh of conductors. The bond balls include outer bond balls and inner bond balls that are fixed to the underside of the substrate. The integrated circuit drives and monitors the anti-tamper security mesh and communicates data using a serial physical interface through a subset of the inner bond balls. In one example, a user has circuitry to be protected. The user purchases the BGA security cap and fits it over the circuitry to be protected such that the integrated circuit of the security cap communicates tamper detect condition information via the serial interface to the underlying protected circuitry and causes sensitive information to be erased or a program to be halted in the event of a tamper condition.
