Background technology
Background technology of the present invention comprises the following aspects
1.1983 the chemically amplified photo resist agent technology of inventions such as the Yi Tengyang of year IBM Corporation.They formed the PHS-BOC ester with poly(4-hydroxystyrene) (PHS) and two tertiary butyl carbonic anhydrides (BOC) with the phenolic hydroxyl group esterification among the PHS at that time.In this compound, add light inlet produce acid source for example phenylbenzene iodine drone salt etc. make photo-resist, coating produces protonic acid through ultraviolet exposure, 100-120 ℃ of heating acid catalyzed reaction (so-called chemical amplification reaction) takes place then, the PHS-BOC ester is decomposed slough carbonic acid gas, again discharge phenolic hydroxyl group, thus by in the alkaline developer insoluble become again solvable.This chemically amplified photo resist agent is used for the photoetching of super large-scale integration silicon chip.Generally use this chemically amplified photo resist agent technology as mega bit order to the super large-scale integration of G position level storage volume in recent years.Can carry out acid catalyzed reaction but this technology must heat just in the later stage, and Heating temperature is higher, 120 ℃ of general requirements, at room temperature the acid-decomposed activity of PHS-BOC ester is extremely low, does not have the possibility of imaging applications, and this is the major defect of this technology.The patent of invention of the visible Yi Tengyang of present technique: USP4,491,628 (1985).
Nineteen ninety 3M company discloses following patent of invention: USP618212 (1990).They obtain the diphenyl acetic acid ester with diphenyl acetic acid and chloromethyl methyl ether, EVE, dihydropyrane, the addition of dihydrofuran isoreactivity olefin(e) compound, these ester compounds produce acid source with photo-thermal and linear phenolic resin mixes with certain proportion, with appropriate solvent dissolve, film, drying, the resist coating that obtains partly produces protonic acid in the uv-exposure post-exposure, the diphenyl acetic acid active ester is decomposed, thereby the available bases water development obtains image, is used for making positive PS printing plate or positive photoresist.Yet very sorry, the invention of 3M company has two big serious problems: 1. product is the low liquid of a kind of viscosity pole, is added in film strength decline in the PS version photosensitive composition, has a strong impact on pressrun.Its anti-printing ink solvent ability is also very poor in addition; Be used for the photo-resist thermotolerance and antiacid erosion is also very poor; 2. this compound is deposited at normal temperatures, particularly runs into light and the moisture decomposition can be quickened, no matter this is that the PS version or the application of photo-resist bring troubling problem with regard to giving.Therefore do not see the report of practicability up to this invention of present 3M company.
The present invention produces under above technical background just.
Summary of the invention
Be subjected to the inspiration of IBM Corporation and 3M company work, we become not only hydroxyl with the intermediate phenylbenzene oxyacetic acid of synthetic diphenyl acetic acid and the condensation under acidic conditions of various phenolic compound but also with the compound of carboxyl, if polyphenol carries out condensation, through thorough shrink can be not only with phenolic hydroxyl group but also with the compound of phenol lactone, and then with these compounds and ethyl vinyl ether, dihydropyrane isoreactivity olefine reaction, can generate in the molecule compound that not only has active ehter bond but also have active ester bond, perhaps not only have active ehter bond but also had the compound of lactone bond.Like this because the increase of molecular weight, product will become near solid arborescens compound, if further modification, might obtain solid resin shape compound, because active ether and active ester all have high acidolysis active, they can have very high sensitivity in sensitization and sensible heat constituent, and help before the acidolysis alkaline-based developer being produced the stronger molten effect of resistance, will be more easily molten in alkaline developer after the acidolysis, thus the difference solubleness before and after the development enlarged, improve image quality.In addition, our these compounds of design should have better stability in storage.So not only solve indeterminable normal temperature acidolysis problem in IBM Corporation's design, and solved two big disadvantages in the invention of 3M company.Another thinking of our this design be hydroxyl compare with the phenolic hydroxyl group of general monomer phenols with the phenol lactone compound or compare with phenolic hydroxyl group in the common resol might have stronger reactive behavior, this as halogenated phenols than phenol easier with EVE generation etherification reaction, this imagination is tested effectively to be confirmed, becomes the present invention's part of dedicating itself to innovation.
Further specify the present invention below: employed benzil acid among the present invention, the phenylbenzene oxyacetic acid, be with traditional synthetic method synthetic, benzil generation isomerization reaction is obtained, also available st-yrax obtains by potassium bromate oxidation and isomerization under alkaline condition, their separation purification method can be used on dissolution filter in the hot water, the method for method that crystallization is under freezing conditions separated out or organic solvent recrystallization.150 ℃ of product fusing points, solvable in ethanol, acetone, ethers and DMF.
Employed phenolic compound can be phenol, meta-cresol, ortho-cresol, p-cresol, 2 among the present invention, 4-xylenol, 2,6-xylenol, p-tert-butylphenol, chlorinated phenol, brominated phenol, cyano group phenol, nitrophenol, Resorcinol, Resorcinol, pyrocatechol, pyrogallol (pyrogallol), Phloroglucinol, hydroxyquinol and alkyl replace compounds such as polyphenol, but will keep an active site on the phenyl ring of these phenolic compounds at least, and this reactive behavior point is sterically hindered as much as possible little.The practical value maximum is in these phenols: Resorcinol, Resorcinol, pyrogallol, Phloroglucinol etc.Using these phenols and the general mol ratio of benzil acid-respons is 1: 1, and perhaps the phenol monomer is suitably excessive.
Solvent for use can be benzene-like compounds such as toluene, dimethylbenzene, halogeno-benzene when synthetic.
Used catalyzer can be sulfuric acid, Phenylsulfonic acid, tosic acid, methylsulfonic acid, phosphoric acid and super acids compounds when synthetic.Consider the solubility in benzene kind solvent and be easy to wash and remove and requirement cheap and easy to get, preferentially use tosic acid and sulfuric acid.
Finding to utilize tosic acid to make catalyzer in the research is that contraposition imports preferential rule for the condensation reaction of phenol and benzil acid, the reactive hydrogen and the hydroxyl in the benzil acid molecule that are the phenol contraposition preferentially carry out condensation, the product of this structure accounts for more than 90%, and meta-cresol, ortho-cresol, p-cresol hydroxyl adjacent condensation ratio is quite big, and and then generation lactone compound, Resorcinol is condensation very easily, just can take place 4 to such an extent as to make solvent with benzene, 6 condensation reaction, and and then thoroughly generate lactone compound, 1,2, the 3-pyrogallol carries out condensation at 4 or 6 equally, and generates lactone compound.Polyphenol such as Resorcinol and Resorcinol all generates lactone compound.
General formula III, employed active olefin has EVE in two compounds shown in the general formula I V synthetic, vinyl butyl ether, vinyl benzyl ether, dihydropyrane, dihydrofuran, pyrrolin isoreactivity alkenyl ether compound, reactive behavior with EVE in these compounds is the highest, can carry out addition esterification or addition etherification reaction at normal temperatures, ring-type ethylene linkage compounds such as dihydropyrane then will react comparatively high temps such as 50-70 ℃, available solvent has a variety of in above-mentioned etherificate and esterification, methylene dichloride wherein, trichloromethane, halohydrocarbon such as trieline are owing to there is heavy atoms effect can quicken etherificate or esterification, thereby preferentially used, for the phenolic compound that is difficult to be dissolved in above-mentioned halohydrocarbon, our employing adds small amount of acetone or tetrahydrofuran (THF) or methyl-sulphoxide and comes the accelerate dissolution reaction process in halogenated hydrocarbon solvent.The hydrogenchloride of minute quantity is also noted that in the hydrochloric ether and should do not contain hydrogenchloride, even because also can cause active ether products to decompose.Phenols affixture or lactone compound shown in same general formula I, the II are not answered the residual catalyst tosic acid yet, otherwise the reaction products therefrom also easily is decomposed.
It is big more to be used for compound shown in synthetic general formula V, the VI required chloromethyl methyl ether or the more little reactive behavior of chloromethyl alkyl oxide molecular weight.Mole or excessive tertiary amine compound such as in reaction process, generally to add, as triethylamine, so that the hydrogenchloride that neutralization generates.Can be used as the compounds such as Trimethylamine 99, trolamine, dimethylethanolamine, pyridine in addition of catalyzer.The chloromethyl methyl ether is that a kind of boiling point has only the bigger compound of toxicity about 57 ℃, and reaction should be carried out under ventilation condition.
More than the purifying and the process for purification of the active ethers of several classes, active ester compound can adopt and inject that big water gaging is washed, separates, washes, separated, the exsiccant purification process, also can take organic solvent extraction, boil off the method for organic solvent behind the separatory again.
We found once that the active rule of the electric nucleophilic reaction of phenolic compound parent was Resorcinol＞Phloroglucinol ≈ pyrogallol＞meta-cresol ≈ phenol ≈ pyrocatechol＞p-cresol ≈ pyrocatechol ≈ Resorcinol.In the synthetic process of compound shown in general formula I, the II, reconfirm this relation that exists, and also have during with compound shown in the synthetic general formula III of compound shown in general formula I, the II, IV, V, the VI this in proper order active substantially.
In the lactone compound molecule of Resorcinol and pyrogallol with phenolic hydroxyl group and ethyl vinyl ether reaction the time show special reactive behavior, in methylene dichloride, need only several minute just can thoroughly finish reaction under the normal temperature as the phenol lactone and the ethyl vinyl ether of Resorcinol.This is the high reaction activity that we seldom see when research phenolic compound and phenol resins and EVE reaction, also is not met report in the document.
