Ta2O5 and Al2O3 thin films were fabricated by pulsed plasma-enhanced chemical vapor deposition (PECVD) with simultaneous delivery of O2 and the metal precursor. By appropriately controlling the gas-phase environment self-limiting deposition at controllable rates (˜1 Å / pulse) was obtained. The process was insensitive to substrate temperature, with a constant deposition rate observed from 90-350° C. As-deposited Ta2O5 films under these conditions displayed good dielectric properties. Performance improvements correlate strongly with film density and composition as measured by spectroscopic ellipsometry and Fourier transform infrared spectroscopy.

This patent describes methods which allow the primary owners of sensitive data to retain more access control over the data they share with secondary service providers, even when the secondary service provider electronically stores some form of this information in a service provider maintained database. When these methods are applied by both data owner and service provider the data can only be accessed and used by the service provider during data owner controlled access sessions. This is accomplished through a special set of methods to apply a set of standard encryptions and a special set of methods to manage the associated cryptographic keys. Unencrypted sensitive data need never be permanently stored in a database. Each data owner has their own unique set of cryptographic keys. Critical decryption keys are never permanently stored in service provider databases. Methods are included to allow previously stored data to be recovered even if the data owner loses or forgets the primary password or access key. Service provider host and database administrators, or hackers who have gained such access, are more effectively blocked from accessing the sensitive data. There is no reliance on obfuscation techniques. Many, many cryptographic keys, not just one, would have to be cryptographically compromised in order to access many records. These methods make massive unauthorized extraction of sensitive data by hackers far more difficult while still supporting effective data sharing suitable for many applications.
