    摘要: The present invention relates to a spin-on antireflective coating composition for a photoresist comprising a polymer, a crosslinking compound and a thermal acid generator, where the polymer comprises at least one functional moiety capable of increasing the refractive index of the antireflective coating composition to a value equal or greater than 1.8 at exposure radiation used for imaging the photoresist and a functional moiety capable of absorbing exposure radiation used for imaging the photoresist. The invention further relates to a process for imaging the antireflective coating of the present invention.

    摘要: The present invention relates to a process for forming an reverse tone image on a device comprising; a) forming an absorbing underlayer on a substrate; b) forming a coating of a positive photoresist over the underlayer; c) forming a photoresist pattern; d) treating the first photoresist pattern with a hardening compound, thereby forming a hardened photoresist pattern; e) forming a silicon coating over the hardened photoresist pattern from a silicon coating composition; f) dry etching the silicon coating to remove the silicon coating till the silicon coating has about the same thickness as the photoresist pattern; and, g) dry etching to remove the photoresist and the underlayer, thereby forming a trench beneath the original position of the photoresist pattern. The invention further relates to a product of the above process and to a microelectronic device made from using the above process.
