IODONIUM SALT COMPOUND, PHOTOACID GENERATOR AND COMPOSITION CONTAINING THE SAME, AND METHOD FOR MANUFACTURING DEVICE

PROBLEM TO BE SOLVED: To provide an iodonium salt compound which can be used as a chemical amplification type photoacid generator for resist and a photocationic polymerization initiator, has high sensitivity to an i-line at a wavelength of 365 nm, and has high solubility to an organic solvent and a resin. SOLUTION: A new iodonium salt compound is represented by the following iodonium salts 2, 5 and 10. SELECTED DRAWING: Figure 1 COPYRIGHT: (C)2019,JPOandINPIT

PHOTOACID GENERATORS

A photoacid generator compound has formula (I): [in-line-formulae]G+Z???(I)[/in-line-formulae] wherein G has formula (II): In formula (II), X is S or I, each R0 is commonly attached to X and is independently C1-30 alkyl; polycyclic or monocyclic C3-30 cycloalkyl; polycyclic or monocyclic C6-30 aryl; or a combination comprising at least one of the foregoing groups. G has a molecular weight greater than 263.4 g/mol, or less than 263.4 g/mol. One or more R0 groups are further attached to an adjacent R0 group, a is 2 or 3, wherein when X is I, a is 2, or when X is S, a is 2 or 3. Z in formula (I) comprises the anion of a sulfonic acid, a sulfonimide, or a sulfonamide. A photoresist and coated film also includes the photoacid generator, and a method of forming an electronic device uses the photoresist.

Diazotisation of aromatic amines and solvolysis of diazonium salts in ethylene glycol ethers

Aniline and unhindered alkyl-substituted anilines undergo solvolysis in dioxane and DME saturated with dry hydrogen chloride on diazotisation with isoamyl nitrite to give 2-(2-chloroethoxy)ethyl aryl ethers and 2-methoxyethyl aryl ethers respectively in 36-47% yields. 2,6-Dialkyl-substituted anilines give the corresponding chloro compounds as the major product along with the aryl ethers in lower yields. Diazotisation of aniline in ethylene glycol and monomethyl ethers of ethylene glycol and diethylene glycol gave the corresponding alcoholysis products in low yields. The solvolysis of aniline did not occur on diazotisation in diethyl ether or THF.

1H NMR Studies on the Interactions of Acyclic Polyethers with Dimethyltin Dichloride in Aromatic Solvents

The interactions between various acyclic polyethers, RO(CH2CH2O)nR'(R, R'=CH3, Ph), and dimethyltin dichloride (DMTC) in aromatic solvents have been studied by means of 1H NMR spectroscopy.On the basis of a continuous variation method, the formation of the 1:1 complexes between glymes, CH3O(CH2CH2O)nCH3 (n=2, 3, 4), and DMTC was revealed in benzene.The 2J(119Sn-CH3) values suggested distorted trans-octahedral configurations for these complexes.From the statistical consideration of stability constants, it was found that the coordination occurred virtually through neighboring two oxygen atoms in these complexes.DMTC gave the complexes of both 1:1 and 1:2 glyme/DMTC stoichiometry with glymes (n=5, 6) in benzene and with all glymes employed here in toluene and 1-chloronaphthalene.Coexistence of 1:1 and 1:2 species was also encountered for PhO(CH2CH2O)nCH3 (n=3, 4, 5), whereas no appreciable interaction was observed between PhO(CH2CH2O)nPh (n=2, 3, 4) and DMTC.On the basis of these observations, the additional formation of the 1:2 complexes was assumed to be caused by the bulkiness of polyethers.
