Patent number: 6582780Abstract: A carbon deposition chamber is provided with several advantages. The substrate and the heating filaments are cooled to a temperature to prevent carbonization by permitting a cooling fluid to be passed through tubing connected to these elements in a heat sink like manner. The substrate is permitted to rotate back-and-forth to permit more even deposition of carbon films onto the substrate. The heating filaments are permitted to expand and contract without breakage by permitting the electrode attached to one end of the filaments to move freely as the filaments change in length. The gas mixture used within the deposition process is expressed from tubing through three zones, which are each individually determined with needle valves.Type: GrantFiled: February 23, 2000Date of Patent: June 24, 2003Assignee: SI Diamond Technology, Inc.Inventor: Zhidan Li Tolt

Patent number: 6580211Abstract: A triode structure code cathode assembly is produced by depositing a carbon emitter material onto a substrate to form a cathode structure. Then, an insulating layer is deposited onto one side of a mesh foil to form a mesh assembly. This mesh assembly is then mechanically attached to the cathode structure so that the insulating layer on the one side of the mesh assembly is contacting the cathode structure. This entire triode cathode assembly can then be used to produce a field emission display device by including an anode structure.Type: GrantFiled: March 9, 2000Date of Patent: June 17, 2003Assignee: SI Diamond Technology, Inc.Inventors: Mohshi Yang, Leif Thuesen, Richard Lee Fink, Zvi Yaniv

Publication number: 20030057821Abstract: Differently sized silicon nanoparticles are used as a phosphor material for cathode ray tubes, field emission displays, or liquid crystal displays. The differently sized particles will emit different light wavelengths, such as red, green, and blue. Thus, the same material can be used for all three phosphors.Type: ApplicationFiled: September 24, 2002Publication date: March 27, 2003Applicant: SI Diamond Technology, Inc.Inventors: Richard Lee Fink, Zvi Yaniv

Publication number: 20030011754Abstract: A method and system for projecting an image. An image projection system may include a sensor configured to detect the presence of an observer within a proximity of a medium, e.g., screen, window. In response to the sensor detecting the presence of an observer within a proximity of the medium, one or more portions of the medium may be switched from a transparent state to a substantially translucent state. At a substantially concurrent time as switching the one or more portions of the medium to a substantially translucent state, an image may be projected onto such portion(s). Hence, an image may be displayed in response to detecting an observer within the proximity of the medium.Type: ApplicationFiled: June 28, 2002Publication date: January 16, 2003Applicant: SI Diamond Technology, Inc.Inventors: Zvi Yaniv, Michael C.

Publication number: 20020185949Abstract: Embossed microstructures within a substrate are used to create narrow and deep holes within that substrate. A carbon nanotube solution or mixture is then deposited over this substrate with the embossed holes. Shaking or vibrating the substrate will then cause the carbon nanotubes to fall into each of the holes in such a way that all of the nanotubes within a hole will be substantially parallel to the long axis of the hole. This structure can then be combined with a gate electrode and an anode to create a field emission display device.Type: ApplicationFiled: June 6, 2002Publication date: December 12, 2002Applicant: SI Diamond Technology, Inc.Inventors: Zvi Yaniv, Richard Fink

Patent number: 6441543Abstract: A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.Type: GrantFiled: January 30, 1998Date of Patent: August 27, 2002Assignee: SI Diamond Technology, Inc.Inventors: Zvi Yaniv, Ronald Charles Robinder
