Disclosed are masks and mask blanks for photolithographic processes, photosensitive materials and fabrication method therefor. Photosensitive materials are used in the masks for recording permanent pattern features via UV exposure. The masks are advantageously phase-shifting, but can be gray-scale masks having index patterns with arbitrary distribution of refractive index and pattern dimension. The masks may have features above the surface formed from opaque or attenuating materials. Alumino-boro-germano-silicate glasses having a composition comprising, in terms of mole percentage, 1-6% of Al2O3, 10-36% of B2O3, 2-20% of GeO2, 40-80% of SiO2, 2-10% of R2O, where R is selected from Li, Na and K, and expressed in terms of weight percentage of the glass, 0-5% of F, can be used for the mask substrate.

Abstract:
Disclosed are masks and mask blanks for photolithographic processes, photosensitive films and fabrication method therefor. Photosensitive films are deposited on a substrate in the masks for recording permanent pattern features via UV exposure. The masks are advantageously phase-shifting, but can be gray-scale masks having index patterns with arbitrary distribution of refractive index and pattern depth. The masks may have features above the surface formed from opaque or attenuating materials. Boro-germano-silicate photosensitive films having a composition consisting essentially, in terms of mole percentage, of: 0-20% of B2O3, 5-25% of GeO2 and the remainder SiO2 can be used for the film. The film is advantageously deposited by using PECVD wherein tetramethoxygermane is used as the germanium source.

Abstract:
Polarizing glass having localized regions or patterns of non-polarizing glass is disclosed. The non-polarizing regions are formed by use of reducing gas-blocking material, local thermal heating of the glass, or by etching techniques. Figures (1a) - (1b) show the reducing gas-blocking method where a shadow mask (4) or a thin layer of material (6) is formed on the surface of the glass (2) to retard the reduction process and enable the production of color gradients and/or designs or patterns in the glass. The masked glass is exposed to a reducing atmosphere such that the reducible phase in the exposed or unprotected regions (8) is reduced and the non-polarizing region (masked region) (10) is not reduced.
Abstract:
The invention is directed to polarizing devices that can be scaled to polarize electromagnetic radiation having wavelengths in ultraviolet to microwave range; and more particularly to devices suitable for use at visible and IR wavelengths. The device has a length, a width and a thickness, and a patterned system of channels, voids or holes embedded in or through a glass matrix and running through the thickness of the glass to thereby polarize incoming electromagnetic radiation having two polarization modes orthogonal to one another, blocking the passage of or reflecting one mode and permitting the other mode to pass through the device. The glass can be any glass suitable for transmitting the electromagnetic radiation in the range it will be used without excessive transmission losses due to absorbance of radiation in that range by moieties present in the glass. In one aspect, the device according to the invention may be deemed a "universal" polarizer: in the sense that it can be made to work in wavelength ranges from the microwave to the ultraviolet. The devices can also be made of polymeric materials utilizing the principles enumerated in the specification.
