摘要:
Novel classes of ionic photoacid generator (PAGs) compounds having relatively environmentally friendly anions with no perfluorooctyl sulfonate (no-PFOS) are provided and photoresist composition that comprise such compounds. The new PAGs produce a photoacid having a short or no perfluoro alkyl chain (i.e., no-PFOS) attached to a variety of functional groups. The PAGs of the invention are useful as photoactive component in the chemically amplified resist compositions used for microfabrication.

摘要:
The present invention is directed to novel radiation-sensitive, wet developable bottom antireflective coating (DBARC) compositions and their use in semiconductor device manufacturing. The DBARC compositions contain a photoacid generator that produces a photoacid upon exposure to activating radiation. In a photolithographic imaging process, the relatively strong photoacid reduces or eliminates scumming. Further, the relatively large size of the photoacid limits its diffusion through the DBARC, thus minimizing or preventing undercut. The inventive method also limits diffusion of the photoacid by controlling the temperature of the post-exposure baking step. Use of the DBARC compositions with a photoresist in photolithography results in highly resolved features having essentially vertical profiles and no scumming and no undercut, which is critical as microelectronics and semiconductor components become increasingly miniaturized.
