    摘要: A first aspect of the present invention is an improved microwave vacuum feed-through device for coupling microwave energy from a microwave wave guide in a substantially atmospheric pressure region into an elongated linear microwave applicator in a sub-atmospheric pressure region. The improved feed-through is designed to match the impedance of the microwave wave guide in the atmospheric pressure region and the improved linear microwave applicator. A second aspect of the present invention is an improved linear microwave applicator for uniformly coupling 95% or more of the microwave energy input thereto into an elongated plasma zone. The applicator includes curved microwave reflector panels which are used to tune the uniformity of the radiated microwave energy along the length of the linear applicator. A third aspect of the present invention is a microwave enhanced chemical vapor deposition method for depositing thin film material. The method includes a step of intensifying the kinetic/thermal energy of the electrically neutral species in the plasma by intensifying the kinetic/thermal energy of the ions in the plasma and thereby, through ion-neutral collisions, intensifying the kinetic/thermal energy of the electrically neutral species. The step of intensifying the kinetic/thermal energy of the ions in the plasma includes subjecting the plasma to either a very low frequency alternating current electrical bias or an alternating polarity magnetic field, the frequency of thereof being less than about 100 kHz.

    摘要: An improved chemical vapor deposition method for the high-rate low-temperature deposition of high-quality thin film material. The method includes the steps of providing an evacuated chamber having a plasma deposition region defined therein; placing a substrate inside the chamber; supplying plasma deposition precursor gases to the deposition region in the evacuated chamber; directing microwave energy from a source thereof to the deposition region, the microwave energy interacting with the deposition precursor gases to form a plasma of electrons, ions and activated electrically neutral species, the plasma including one or more depositing species; increasing the surface mobility of the depositing species in the plasma by coupling additional non-microwave electronic energy and magnetic energy into the plasma, without intentionally adding thermal energy to the substrate or precursor gas; and depositing a thin film of material onto the substrate.

    摘要: A data storage medium which includes a transition metal as a switching modulator is disclosed. The data storage medium is switchable by projected beam energy, has an erased signal to noise ratio that is substantially invariant with respect to written storage time, and a contrast ratio that is substantially invariant with respect to cycle history. The data storage medium is substantially oxygen free and comprises a chalcogenide and a switching modulator. The switching modulator is a transition metal, especially from the right hand column of Group VIII, e.g. nickel (Ni), palladium (Pd), and platinum (Pt). The concentration of the switching modulator in the data storage medium is high enough to suppress grain growth during written storage, to provide random crystallite orientation and to increase the erase velocity, but low enough to permit discrimination between detectable written and erased states of the data storage medium.
