Abstract: The disclosure is directed to systems, apparatus, and methods for online purchasing. In one example, a system includes a web server that presents purchase options and receives user input. The system may also include an application server that attempts to authenticate users to existing accounts using an account identifier, such as a user ID or email address. If a user does not provide an identifier corresponding to an existing account, the application server may create a new account. If the user provides an identifier corresponding to an existing account, but does not provide a valid password, the application server may create a provisional account. The application server may also associate purchases with the user's account and provide access to the purchased product. Purchases associated with a provisional account may be resolved with an existing or newly-created permanent account when additional user information is received, such when the product is registered.

Abstract: A process has been developed for fabricating a nonpolar low loss thin film capacitor utilizing tantalum oxide for high capacitance per unit area as a dielectric which is deposited in film form relative to a suitable substrate. A counter electrode is deposited on a substrate. A film of metal having a high recrystallization temperature is deposited on the counter electrode. This deposition forms the bottom electrode of the capacitor structure. The metal film has a quality thermal expansion resistance and a high reliability in thermal environments.
