  • Publication number: 20030092348
    Abstract: An interactive ride-on toy, having a stuffed toy horse's head which includes ears, a movable mouth and is connected to a stick. One or more buttons, each with an icon depicting an image, is positioned on one or both ears of the horse's head. An electronically programmed chip responds to activation of the button to operate a speaker and a mechanism for moving the horse's mouth, the speaker playing sounds relating to the image depicted on each button.
    Type: Application

  • Patent number: 6251190
    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.

  • Patent number: 6206967
    Abstract: A multiple step chemical vapor deposition process for depositing a tungsten film on a substrate. A first step of the deposition process includes a nucleation step in which a process gas including a tungsten-containing source, a group III or V hydride and a reduction agent are flowed into a deposition zone of a substrate processing chamber while the deposition zone is maintained at or below a first pressure level. During this first deposition stage, other process variables are maintained at conditions suitable to deposit a first layer of the tungsten film over the substrate. Next, during a second deposition stage after the first stage, the flow of the group III or V hydride into the deposition zone is stopped, and afterwards, the pressure in the deposition zone is increased to a second pressure above the first pressure level and other process parameters are maintained at conditions suitable for depositing a second layer of the tungsten film on the substrate.
