Abstract
Anti-reflective coating materials for deep ultraviolet photolithography include one or more organic dyes incorporated into spin-on-glass materials. Suitable dyes are strongly absorbing over wavelength ranges around wavelengths less than 260 nm such as 248 nm and 193 nm, that may be used in photolithography. A method of making dyed spin-on-glass materials includes combining one or more organic dyes with alkoxysilane reactants during synthesis of the spin-on-glass materials.
