摘要:
A titania precursor (18) and a silica precursor (6) are mixed in a manifold (14) and are fed to a burner (28) to create soot (40) which is deposited on a deposition surface (34) which is rotated and elevated. The end product is useful for Extreme UV lithography.
摘要:
The present invention describes an extrusion process for manufacturing a titanium-containing silicate glass honeycomb structure (100), having a variety of shapes and sizes depending on its ultimate application. The titanium-containing glass honeycomb has a very low coefficient of thermal expansion (CTE) and the CTE can be varied by adjusting the titanium level to match the CTE of members that are bonded to the honeycomb. Furthermore, the inventive honeycomb structure is lightweight, yet able to advantageously used as a light-weight support for such objects as mirrors. Especially extraterrestrial environments where temperature extremes are present. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.

The present invention describes a glass honeycomb structure (100) having a variety of shapes and sizes depending on its ultimate application. Unlike prior art honeycomb structures made from ceramics, the inventive glass honeycomb can be readily bent and/or redrawn. Furthermore, the inventive honeycomb structure is light-weight, yet able to support heavy loads on its end faces (10a, 10b). Therefore, the inventive honeycomb can be used as a light-weight support for such objects as mirrors. Other useful properties of the extruded glass honeycomb are its high softening temperature, its transparency to ultraviolet and visible light, and its ability to be redrawn. Embodiments that rely upon one or more of these properties include: a bio-reactor, a membrane reactor, a capillary flow controller, a high efficiency filtration system, in-situ water treatment, high temperature dielectric material, and photonic band gap material.

The present invention describes an extrusion process for manufacturing a glass honeycomb structure (100) having a variety of shapes and sizes depending on its ultimate application. Unlike prior art honeycomb structures made from ceramics, the inventive glass honeycomb (100) can be readily viscously bent and/or redrawn. Furthermore, the inventive honeycomb structure (100) is light-weight, yet able to support heavy loads on its end faces (10a, 10b). Therefore, the inventive honeycomb (100) can be used as a light-weight support for such objects as mirrors. These honeycombs (100) can be used singularly or in aggregates to provide such support.

The invention provides optical projection lithography methods, photolithography photomasks, and optical photolithography mask blanks for use in optical photolithography systems utilizing deep ultraviolet light (DUV) wavelengths below 300 nm, such as DUV projection lithography systems utilizing wavelengths in the 248 nm region and the 193 nm region. The invention provides improved production of lithography patterns by inhibiting polarization mode dispersion of lithography light utilizing low birefringence mask blanks and photomasks.
