    Abstract: The method and apparatus of the invention create a dynamic Soret effect for propelling a target chemical constituent along a pathway. A moving temperature profile impressed upon the pathway produces consecutive alternating warmer and cooler zones along the path which transport components of a mixture down the path according to their respective diffusivities. In one embodiment, the invention provides a dynamic thermophoretic concentrator for separating a target chemical constituent from a mixture of components on the basis of diffusion coefficient by using alternate forward and backward motion of a temperature profile along the pathway, thereby accumulating an ultimate concentration of the target constituent greater than its initial concentration in the mixture.

    Abstract: Anti-reflective coatings and methods for forming these anti-reflective coatings are disclosed that have a polymer chemistry and optical characteristics suitable for suppressing the light that reflects off a circuit substrate during a photolithographic process. These anti-reflective coatings include a phenolic polymer material and an epoxide-containing polymer material that can be combined in a select proportion to form a thermally curable polymeric anti-reflective coating. The select proportions of the combined materials tailors the optical characteristic of the anti-reflective coating to attenuate energy about a select range of wavelengths.

    Abstract: Methods for the preparation of multilayered resists are described. A first layer of photoresist is deposited onto a substrate. First portions of the first layer are exposed to a first dose of radiant energy. A second layer of photoresist is deposited at atop the first layer and second portions of the second layer are exposed to a second varied dose of radiant energy. The dose is modulated over different portions of a layer to preferentially enhance development within the interior of the structure to reduce total development times.

    Abstract: The present invention provides photoresist materials for use in photolithography at wavelengths less than about 248 nm. More particularly, the photoresists of the invention are particularly suited for use in 157 nm lithography. A photoresist composition of the invention includes a polymer having at least one monomeric unit having an aromatic moiety. The monomeric unit further includes at least a group, such as an electron withdrawing group, attached to the aromatic moiety. The attached group includes at least one CF bond. The polymer further includes an acidic hydroxyl group. A photoresist composition of the invention can have an absorbance in a range of 1-5 &mgr;m−1 at 157 nm, rendering it particularly suitable for use as a single layer resist in 157 nm lithography.
