His work focuses on developing advanced materials that enhance the performance and efficiency of photoresist compositions.
Latest Patents
Simison's latest patents include innovative solutions such as photosensitive dissolution inhibitors and resists based on onium salt carboxylates. This photoresist composition utilizes onium salt carboxylates as thermally stable dissolution inhibitors. The composition can be formulated with an onium carboxylate salt and a phenolic photoresist, such as novolac, or an onium cation protected carboxylate-containing resin like an acrylic/acrylic acid copolymer. Notably, the onium carboxylate can be an iodonium cholate, specifically preferred as octyloxyphenyphenyl iodonium cholate. This composition is designed to avoid the generation of nitrogen or other gaseous byproducts upon exposure to radiation, does not require water for photoactivation, and maintains thermal stability at the necessary temperatures for solvent removal.
Another significant patent involves a photoimageable composition that incorporates photoacid generators, including alkoxyphenylphenyliodonium salt and/or bis(t-butylphenyl)iodonium salt. This composition is particularly effective in improving resolution and is suitable for producing high aspect ratio microstructures. The preferred alkoxyphenylphenyliodonium salts include 4-octyloxyphenyl phenyliodonium hexafluoroantimonate and 4-methoxyphenyl phenyliodonium hexafluoroantimonate.
