Abstract: A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a cathodic structure which is formed within an active area on a backplate. The cathodic structure includes a row metal composed of strips of aluminum overlain by a layer of cladding material. The use of aluminum and cladding material to form row metal gives row metal segments which are highly conductive due to the high conductivity of aluminum. By using a suitable cladding material and processing steps, a bond between the aluminum and the cladding material is formed which has good electrical conductivity. In one embodiment, tantalum is used as a cladding material. Tantalum forms a bond with the overlying resistive layer which has good electrical conductivity. Thus, the resulting structure has very high electrical conductivity through the aluminum layer and high conductivity into the resistive layer.

Abstract: A field emission device is disclosed having a buffer layer positioned between an underlying cathode conductive layer and an overlying resistor layer. The buffer layer consists of substantially undoped amorphous silicon. Any pinhole defects or discontinuities that extend through the resistor layer terminate at the buffer layer, thereby preventing the problems otherwise caused by pinhole defects. In particular, the buffer layer prevents breakdown of the resistor layer, thereby reducing the possibility of short circuiting. The buffer layer further reduces the risk of delamination of various layers or other irregularities arising from subsequent processing steps. Also disclosed are methods of making and using the field emission device having the buffer layer.

Abstract: A method for forming an emitter tip for use in a field emission device. An emitter layer is provided over a substrate. The emitter layer is overlaid with a blanket dielectric which is in turn overlaid by a masking layer. In a first etching operation, a masking island and an underlying dielectric island are formed from the masking layer and the blanket dielectric, respectively. These islands serve as a masking structure during subsequent etching processes by which an emitter tip is formed from the emitter layer. Accordingly, a second etching operation is conducted, whereby an etch chemistry which exhibits both isotropic and anisotropic characteristics is used to remove a portion of the emitter layer by undercutting beneath the masking structure. A third etching operation is conducted, wherein the etch chemistry is substantially more anisotropic than the etch chemistry of the second etching operation. The second and third etches mobilize a portion of the masking layer and form an emitter tip from the emitter layer. The emitter tip has a substantially rectilinear vertical profile.

Abstract: An infrared lamp with a closed-off enveloping tube which encloses an emission source joined with contacts for a power supply in the form of a carbon ribbon which, extending in a direction of a long axis of the enveloping tube, determines an irradiation length of the infrared lamp in the sense of a higher irradiation output. The carbon ribbon has a length which is larger than the irradiation length by a factor of at least 1.5. With a procedure for heating a material to be processed using the infrared lamp, which makes possible short processing times in connection with a simultaneous high degree of energy efficiency, the infrared lamp may be operated such that its maximum emission lies within a wavelength range from 1.8 &mgr;m to 2.9 &mgr;m, and such that its power output comes to at least 15 Watts per cm3 of the volume enclosed by the enveloping tube over the irradiation length.
