Title: Photosensitive dissolution inhibitors and resists based on onium salt carboxylates

Abstract

A photoresist composition that employs onium salt carboxylates as thermally stable dissolution inhibitors. The photoresist composition can be either an onium carboxylate salt with a phenolic photoresist, such as novolac, or an onium cation protected carboxylate-containing resin such as an acrylic/acrylic acid copolymer. The onium carboxylate can be an onium cholate, wherein the onium cholate is an iodonium cholate. Particularly preferred iodonium cholates are alkyloxyphenylphenyl iodonium cholates and most particularly preferred is octyloxyphenyphenyl iodonium cholate. The photoresist composition will not create nitrogen or other gaseous byproducts upon exposure to radiation, does not require water for photoactivation, has acceptable UV radiation transmission characteristics, and is thermally stable at temperatures required for solvent removal.

  • Accumulators having solution electrodes containing manganese dioxide and lead dioxide as active material on the cathode side and containing acid electrolytes are discussed. The electrolyte has a content of onium salts soluble in aqueous medium.
  • A method of and apparatus for continuously making an organic ester from a lower alcohol and an organic acid is disclosed. An organic acid or salt is introduced or produced in an electrode ionization (EDI) stack with a plurality of reaction chambers each formed from a porous solid ion exchange resin wafer interleaved between anion exchange membranes or an anion exchange membrane and a cation exchange membrane or an anion exchange membrane and a bipolar exchange membranes. At least some reaction chambers are esterification chambers and/or bioreactor chambers and/or chambers containing an organic acid or salt. A lower alcohol inmore » the esterification chamber reacts with an anion to form an organic ester and water with at least some of the water splitting with the ions leaving the chamber to drive the reaction.« less
  • Onium salt chemistry can be used to deposit very uniform thickness stationary phases on the wall of a gas chromatography column. In particular, the stationary phase can be bonded to non-silicon based columns, especially microfabricated metal columns. Non-silicon microfabricated columns may be manufactured and processed at a fraction of the cost of silicon-based columns. In addition, the method can be used to phase-coat conventional capillary columns or silicon-based microfabricated columns.
  • The necessity of mastering alternative lithographic processes for development and production of 64 and 256 Mbit dynamic random-access memory units has been substantiated. It is shown that conventional positive photoresists based on diazonaphthoquinone and novalac resins do not meet the requirements of modern microlithography. The concept of chemical amplification offered a means for developing adequate topological structures with sizes of resist components of 0.35 {mu}m or less. Onium salts are universal and efficient acid generators for resists with chemical amplification. Studies in the field of photo- and radiochemistry of onium salts have been summarized and correlated. It has been shownmore » that the quantum yield and distribution of photolysis products are governed to a major extent by geminal and bulk recombination. Specific features of photolysis and radiolysis of onium salts in a polymer matrix are considered.« less
