Abstract:
In order to reduce contamination of optical elements which comprise a multilayer system on a substrate, it is proposed that the layer material and/or the layer thickness of at least one layer of the multilayer system are/is selected such that the standing wave which forms during reflection of the irradiated operating wavelength, forms a node of the electrical field intensity (node condition) in the area of the free interface of the multilayer system. Furthermore, a method for determining a design of a multilayer system, as well as a manufacturing process and a lithography apparatus are described.

Further, the invention also provides a liquid crystal element and a liquid crystal device having said positive-negative-blended optical retardation film.
Abstract:
A carrier supporting titania thereon is further caused to carry a metal compound thereon. This metal compound is hydrogen reduced in a heating atmosphere at a first treatment temperature, then oxidized in a heating atmosphere at a second treatment temperature not higher than the first treatment temperature to thereby obtain a photocatalyst. In this event, metal is released from an extremely strong reduction state and thus highly dispersed on the catalyst in the form of fine particles so that high activity of the catalyst can be obtained. Then, by purifying gas while feeding light and heat to the photocatalyst by, for example, blacklights, a volatile organic compound such as acetaldehyde can be decomposed at a high decomposition rate through cooperation between photocatalytic activity and thermal catalytic activity of the photocatalyst.
Abstract:
A method of preparing semiconductor nano crystal anatase TiO2 solution uses titanium alkoxide Ti(OR)4 as a main component in combination with chelating agents in aqueous solution. A fluorescent lamp tube is coated with the semiconductor nano crystal anatase TiO2 solution to form a photocatalytic coating fluorescent lamp capable of cleaning air. Then a baking step is carried out at a low temperature about 100-250null C. By doped anatase TiO2 with small amount about 0-1.0 wt % of precious metals complex or transition metals oxides as nano-particle on or in the anatase TiO2 nano-particle surface, the visible light photocatalysis efficiency is increased for air cleaning. By doped with small amount Eunull3 or rare earth metal ion on or in the anatase TiO2 nano-particle surface, which is a photocatalytic material acting as fluorescent agent, the fluorescent lamp has increasing brightness of when it is turned on.

A method for fabricating patterns of a reflective thin film transistor liquid crystal display (TFT-LCD) includes: providing a substrate (300); forming a TFT layer (310) on the substrate; coating a photo resist layer (320) on the TFT layer; pre-baking the photo resist layer; patterning the photo resist layer with a transcribing mold (400) having specific patterns; and further baking the photo resist layer. By using the transcribing mold, the shapes, precision and angles of the patterns can be accurately controlled, thereby easily providing a desired photo resist layer.
Abstract:
An apparatus for manufacturing a printed light guide plate includes a working platform (23), and a heater (24) coupled to the working platform. A transparent slab (21) is disposed on the working platform. The purpose of coupling the heater to the working platform is to maintain the transparent slab a constant temperature in the range from about 40null C. to about 45null C., such that as few water molecules as possible are absorbed into the transparent slab. The quality of the manufactured printed light guide plate is thus improved.

A method of producing an anti-reflection film includes forming a first layer on a transparent substrate, forming a second layer on the first layer, and forming the third layer on the second layer. When an optical admittance Y at a surface of the second layer is represented by, 1 Y = H E = ( x + iy ) where i is the imaginary number unit, thicknesses and reflective indexes of the substrate, first layer, second layer, and third layer are selected so that x and y satisfy the following formula, 0.9xnull(n2nulln02)/2n0null2
Abstract:
The invention relates to a method for forming a multilayer thin film and an apparatus thereof, which are able to form a thin layer at an accuracy of 0.5 nanometers or less on at least a specified layer during formation on a substrate (W) and to increase the yield of multilayer thin film products. X-rays are irradiated from X-ray irradiating means (6) onto the surface of a multilayer thin film during formation on the substrate (W) at angles from 0 to 1.5 degrees, and the obtained reflected X-rays are measured by X-ray measuring means (7) while varying the incident angle null, wherein reflectivity curve depicting the intensities of the reflected X-rays are obtained with respect to the scattering angle 2null, and the reflectivity curve, whose scattering angles exist in a range of 0 to 1 degree, of the reflectivity curve is analyzed. Herein, the thickness of a thin layer during formation is estimated, and a thin layer having a prescribed thickness is formed by controlling the thickness of a layer during formation, utilizing the estimated results.
