Abstract:
A wire grid polarizer (WGP) (10) can have a conformal-coating (13) to protect the WGP (10) from oxidation and/or corrosion. The conformal-coating (13) can include a barrier layer with at least one: of aluminum oxide, silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, hafnium oxide, and zirconium oxide. A method of making a WGP (10) can include applying the barrier layer over ribs (12) of a WGP (10) by vapor deposition.
Abstract:
A method and system (10, 20, 30, 50) for reducing static charges on a material (18). X-rays (13) can ionize a flowing fluid (16). The ions can be transported to the material and can reduce or dissipate the static charges.
Abstract:
The invention includes a flat-panel-display (FPD) manufacturing machine (10, 20, 30, and 40) which utilizes x-rays from x-ray tubes (11) for electrostatic dissipation of a bottom side of a FPD (13) when lifting the FPD off of a table (12) by lift-pins (19) during manufacture of the FPD. The invention also includes a method of electrostatic dissipation of a bottom side of an FPD.
Abstract:
In one embodiment, the invention includes an x-ray source (10, 20, 30, 40, 50, 110) having a cathode with a pointed end (9) or an elongated blade (113) oriented substantially transverse with respect to a longitudinal axis (6) of the cathode (11). The pointed end or blade can be pointed towards an anode (14). In another embodiment, the invention includes an x-ray source (60) having a window (16) with an annular-shape (66), forming a hollow-ring. A convex portion of a half-ball-shape (64) of an anode (14, 140) can extend into a hollow of the annular-shape of the window.
Abstract:
An x-ray tube (10, 40, 50) including dual, electrically-conductive emitter tubes (14i, 14o) to support and provide electrical power to an electron emitter (18). A method of evacuating and sealing the x-ray tube by drawing a vacuum on the x-ray tube through an inner tube of dual emitter tubes, then pinching the inner tube to seal off the enclosure and to maintain a vacuum therein.
Abstract:
A wire grid polarizer (10, 20, 30, 40, 50, 60, 70, 80, 90, 100) comprising an array of parallel, elongated first rib groups (14) disposed over a substrate (11). Each first rib group can comprise a central first transmissive rib (12) and a pair of first wires (13) including a first wire disposed along each side of the first transmissive rib. A first dielectric material (16) can substantially fill first gaps between each rib group and an adjacent rib group. An array of parallel, elongated second wires (15) can be disposed over the rib groups and the first dielectric material. The first wires or the second wires can be absorptive and the other of the first wires or the second wires can be reflective.
Abstract:
A multiple wavelength x-ray source (10) includes a multi-thickness target (14, 14b, 14c, 14d), having at least a first and a second thickness (T2, Tl). The first thickness can substantially circumscribe the second thickness. An electron beam (21) can be narrowed to impinge primarily upon second thickness or expanded to impinge primarily upon the first thickness while maintaining a constant direction of the beam. This invention allows the target thickness to be optimized for the desired output wavelength without the need to redirect or realign the x-rays towards the target.
Abstract:
A radiation detector (40) has an integrated collimator (44). The collimator may be deposited on an anode (12) or cathode (18)face of the radiation detector. An insulating material (46) may be deposited between the collimator and the radiation detector if the collimator is deposited on the anode side. The collimator may be comprised of a single layer or of multiple layers (44a-c). Patterning and etching may be used to create an aperture (45) in the collimator to allow x-rays to impinge on a full charge collection region (17) of the radiation detector intrinsic region (11).
Abstract:
A silicon drift detector (SDD) (50, 60, 80, 90) comprising electrically isolated rings (51, 81, 91). The rings can be individually biased doped rings. One embodiment includes an SDD with a single doped ring. Some of the doped rings may not require a bias voltage. Some of the rings can be field plate rings (94a-e). The field plate rings may all use the same biasing voltage as a single outer doped ring. The ring widths can vary such that the outermost ring is widest and the ring widths decrease with each subsequent ring towards the anode.
Abstract:
Light enhancement devices (10), applications for the light enhancement devices (10), and methods for making the light enhancement devices are provided. The light enhancement devices (10) include a substrate (11) and a film of metal (12) disposed over the substrate (11), the film of metal (12) including at least one cavity (13). The cavity (13) may be of various shapes depending on the desired application.
