摘要:
The present invention relates to a spin-on anti reflective 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 anti reflective 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 process for making a siloxane polymer which comprises at least one Si-OH group and at least one Si-OR group, where R is a moiety other than hydrogen, comprising reacting one or more silane reactants together in the presence of a hydrolysis catalyst in either a water/alcohol mixture or in one or more alcohols to form the siloxane polymer; and separating the siloxane polymer from the water/alcohol mixture or the alcohol(s).
