Title: Improved gate electrode connection structure by in situ chemical vapor deposition of tungsten and tungsten nitride
Inventor: MAK ALFRED
IPC: H01L21/768
Filed: 1999-06-01
Granted: 2001-06-07
Abstract: A gate electrode connection structure formed by deposition of a tungsten nitride barrier layer and a tungsten plug, where the tungsten nitride and tungsten deposition are accomplished in situ in the same chemical vapor deposition (CVD) chamber. The tungsten nitride deposition is performed by plasma enhanced chemical vapor deposition (PECVD) using a plasma containing hydrogen, nitrogen and tungsten hexafluoride. Before deposition the wafer is pretreated with a hydrogen plasma to improve adhesion. The tungsten deposition process may be done by CVD using tungsten hexafluoride and hydrogen. A tungsten nucleation step is included in which a process gas including a tungsten hexafluoride, diborane and hydrogen are flowed into a deposition zone of a substrate processing chamber. Following the nucleation step, the diborane is shut off while the pressure level and other process parameters are maintained at conditions suitable for bulk deposition of tungsten.

Title: Enhancing concealment in the presence of fine mistuning for various TV scrambling techniques
Inventor: QUAN RONALD
IPC: H04N7/169
Filed: 1999-07-21
Granted: 2001-03-01
Abstract: An improved method and apparatus for maintaining concealment for a scrambled signal when frequency pre-emphasis is used to defeat the scrambling. The pre-emphasis may be synthesized with high pass or peaking circuitry. More commonly however the pre-emphasis is available in television sets with a fine tuning control. By adjusting the fine tuning control to cause purposely mistuning off center, a peaking effect is generated which is used to counter the scrambled signal. The application discloses one embodiment which uses de-emphasis to counter the peaking effect. In another embodiment, signals added in the vicinity of the horizontal blanking interval causes the peaking effect to enhance these added signals over stable edges of the video signal. Since these added signals are position modulated for example, the television's sync circuits and horizontal oscillator circuits will cause scan circuits to generate position modulation. Thus adding a specific type of signal causes the peaking circuit to enlarge the added signals more than the other parts of the video signal for synchronization.
