  • Publication number: 20120313153
    Abstract: According to one embodiment of the invention, the gate contact is formed by a selective deposition on the gate electrode. One acceptable technique for the selective deposition is by plating. Plating is one process by which a metal structure, such as a gate contact, may be formed directly on the gate electrode. The plating is carried out by immersing the semiconductor die in a plating solution with the gate electrode exposed. The gate contact is plated onto the gate electrode and thus is ensured of being fully aligned exactly to the gate electrode. After this, the appropriate dielectric layers are formed adjacent the gate contact and over the source and drain to ensure that the gate electrode is electrically isolated from other components of the transistor.

  • Publication number: 20120203733
    Abstract: Personal Cloud Engine (iCloud) described in the present invention collects information relevant to a user from various data sources including personal email accounts, social network accounts, online vendors, on-line services for store and share photos and videos and on-line bank accounts. Collected data are classified, indexed, tagged and stored in a persistent data storage device. Web interface such as HTTP is provides for access data by a client, which can be web browser running on a computing device or a client application running on a smart phone. By gathering all the data, iCloud maintains a secondary copy of all valuable personal data and effectively prevents data loss. iCloud can also utilize the data and extract intrinsic value from the data stored by data mining and analytic tools.
