分析用樣品之回收方法及其利用 Method for recovering sample for analysis and its utilization

本發明係關於分析用樣品之回收方法、分析方法、品質管理方法、製造方法及裝置。 The present invention relates to a method for recovering a sample for analysis, an analysis method, a quality management method, a manufacturing method, and an apparatus.

目前於各領域,已有利用於物品表面上形成膜的技術。此種膜係以例如,著色、拋光、防鏽、防污、防霧、絕緣、賦予導電性等各式各樣的目的被形成。例如於電子裝置、光學裝置、生物裝置、磁性裝置等之領域形成具有特定機能的膜已被進行。又,伴隨此等,為了評價物品之性能、品質等,膜中所含成分之分析成為重要。 Currently in various fields, it has been advantageous to use a technique for forming a film on the surface of an article. Such a film is formed for various purposes such as coloring, polishing, rust prevention, antifouling, antifogging, insulation, and imparting conductivity. Forming a film having a specific function, for example, in the fields of an electronic device, an optical device, a biological device, a magnetic device, or the like, has been performed. Further, along with these, in order to evaluate the performance, quality, and the like of the article, analysis of the components contained in the film is important.

例如,於許多有機電子裝置(organic electronics device)已使用含有有機物的薄膜(有機薄膜)。為了評價此類有機電子裝置之性能、品質等,分析該裝置上形成的有機薄膜之成分成為必要。例如,成為有機薄膜的材料的有機化合物係冀望對裝置特性無影響,且為雜質少的高純度品。因此,對該有機化合物的各種純化方法及分析方法正被開發。又,與成為材料的有機化合物同樣地,認為有機薄膜中之雜質亦對裝置特性有影響。除了來自材料的污染之外,藉由來自成膜步驟的污染(例如來自裝置、操作的污染)等,於有機薄膜有混入多種雜質之虞。於製作高品質的有機薄膜上,有必要於彼等雜質進行微量區域的評價。 For example, a film (organic film) containing an organic substance has been used in many organic electronic devices. In order to evaluate the performance, quality, and the like of such an organic electronic device, it is necessary to analyze the composition of the organic thin film formed on the device. For example, an organic compound which is a material of an organic thin film is a high-purity product which does not affect the device characteristics and which has few impurities. Therefore, various purification methods and analysis methods for the organic compound are being developed. Further, similarly to the organic compound to be a material, it is considered that impurities in the organic film also affect the device characteristics. In addition to contamination from materials, organic thin films are contaminated with various impurities by contamination from the film forming step (for example, contamination from equipment, handling). In the production of high-quality organic films, it is necessary to evaluate the trace regions of their impurities.

就分析於有機薄膜所含成分的方法而言,例如可列舉(1)於基板 上之有機薄膜照射離子或X射線等,而直接測定該有機薄膜中之雜質的方法(XPS、XRD、TXRF、TOF-SIMS、SIMS、GD-OES等);(2)將有有機薄膜形成的基板浸漬於有機溶媒中,而將有機薄膜溶解於有機溶媒後,處理溶解液而測定的方法(ICP-MS、IC、LC、GC等);(3)將基板上之有機薄膜以高溫處理後,而測定的方法(ICP-MS、GC等)。例如,(1)之方法已記載於非專利文獻1至4。 For the method of analyzing the components contained in the organic film, for example, (1) a substrate can be cited. The method of directly measuring the impurities in the organic film by irradiating ions or X-rays, etc. (XPS, XRD, TXRF, TOF-SIMS, SIMS, GD-OES, etc.); (2) forming an organic film a method in which a substrate is immersed in an organic solvent, and an organic film is dissolved in an organic solvent, and the solution is treated to measure the solution (ICP-MS, IC, LC, GC, etc.); (3) after the organic film on the substrate is treated at a high temperature And the method of measurement (ICP-MS, GC, etc.). For example, the method of (1) has been described in Non-Patent Documents 1 to 4.

附帶一提,就剝離基板表面之有機薄膜的方法而言,專利文獻1已記載對含水蒸氣的自由基原料氣體施加電場而生成含羥基自由基的氣體,藉由將含此羥基自由基的氣體供給於經加熱的基板表面,而將基板表面之有機薄膜及污染物質剝離洗淨的剝離洗淨方法。又,專利文獻2已記載作為阻膜(resist)等的有機膜之剝離前處理,使有機膜暴露於藥液的蒸氣氣體之剝離方法。 Incidentally, in the method of peeling off the organic thin film on the surface of the substrate, Patent Document 1 discloses that an electric field is applied to a radical gas source containing water vapor to generate a gas containing a hydroxyl radical, and a gas containing the hydroxyl radical is used. A peeling cleaning method for supplying the surface of the heated substrate to remove the organic thin film and the contaminant on the surface of the substrate.

[發明概要] [Summary of the Invention]

然而,如上述之歷來技術,有無法獲得用以高敏感度定量有機薄膜等的有機膜所含成分之分析用樣品的問題點。 However, as described above, there is a problem in that it is impossible to obtain a sample for analysis of a component contained in an organic film such as a highly sensitive organic film.

例如,前述(1)之方法,於照射的離子或X射線到達基板的情形,藉由來自基板之雜質,測定的敏感度會降低。又,(1)之方法僅為有機薄膜表面之半定量分析法,無法分析有機薄膜全體。 For example, in the method of the above (1), when the irradiated ions or X-rays reach the substrate, the sensitivity of the measurement is lowered by the impurities from the substrate. Further, the method of (1) is only a semi-quantitative analysis method of the surface of the organic film, and it is impossible to analyze the entire organic film.

前述(2)之方法,因將每個基板之有機薄膜浸漬於有機溶媒,由於來自基板及有機溶媒的污染而以高敏感度之評價為困難的。又,於高溫處理的情形,由於來自器具、環境的污染、目的成分之揮發等,以高敏感度及高回收率之評價為困難的。再者,亦可能產生來自複雜操作的操作污染。 In the method of the above (2), since the organic thin film of each substrate is immersed in the organic solvent, it is difficult to evaluate the high sensitivity due to contamination from the substrate and the organic solvent. Further, in the case of high-temperature treatment, it is difficult to evaluate high sensitivity and high recovery rate due to contamination from equipment, the environment, and volatilization of the target component. Furthermore, operational contamination from complex operations can also result.

前述(3)之方法亦同樣地,由於來自基板之污染、來自高溫處理中之器具或環境的污染、目的成分之揮發等,以高敏感度及高回收率之評價為困難的。因此,前述(1)至(3)之方法有各自的問題。 Similarly, in the method of the above (3), it is difficult to evaluate the high sensitivity and the high recovery rate due to contamination from the substrate, contamination from equipment or the environment during high-temperature treatment, and volatilization of the target component. Therefore, the methods of the above (1) to (3) have respective problems.

另一方面,專利文獻1記載之剝離洗淨方法的技術領域係以阻膜薄膜為對象的剝離洗淨方法,有機薄膜自基板被剝離的同時,被分解及去除。又,專利文獻2記載之剝離方法係使產生阻膜等之有機膜變形、或變質化後作剝離處理。即,專利文獻2記載之剝離方法亦與專利文獻1記載之剝離洗淨方 法同樣地,亦以去除有機膜為目的。據此,藉由專利文獻1及2記載之技術,無法回收高敏感度之分析用樣品。 On the other hand, the technical field of the peeling cleaning method described in Patent Document 1 is a peeling and cleaning method for a film of a resist film, and the organic film is decomposed and removed from the substrate. Further, in the peeling method described in Patent Document 2, the organic film such as the resist film is deformed or denatured, and then subjected to a peeling treatment. In other words, the peeling method described in Patent Document 2 is also the peeling and cleaning method described in Patent Document 1. In the same way, the purpose of removing the organic film is also adopted. According to this, the high-sensitivity analysis sample cannot be recovered by the techniques described in Patent Documents 1 and 2.

<蒸氣接觸步驟> <Vapor contact step>

本發明之回收方法之特徵為包含蒸氣接觸步驟。於蒸氣接觸步驟,使上述有機膜與蒸氣接觸。藉由使有機膜與蒸氣接觸,可減弱構成前述有機膜的分子彼此的結合及/或前述有機膜與前述基材之表面的結合。據此,自基材剝離有機膜、或有機膜被溶解。因此,可不分解基材本身,選擇性地分析僅來自有機膜的成分而回收作為分析用樣品。據此,可最小限度地保留基材所含雜質的溶出。又,可以高回收率回收有機膜所含成分。而且,藉由將回收的有機膜以分析有機物的各種高敏感度分析方法加以分析,可以高敏感度分析有機膜所含成分而加以評價。 The recovery method of the present invention is characterized by comprising a vapor contacting step. The organic film is brought into contact with the vapor in the vapor contacting step. By bringing the organic film into contact with the vapor, the bonding of the molecules constituting the organic film and/or the bonding of the organic film to the surface of the substrate can be weakened. According to this, the organic film is peeled off from the substrate, or the organic film is dissolved. Therefore, it is possible to recover the sample for analysis without selectively decomposing the substrate itself and selectively analyzing the component derived only from the organic film. According to this, the elution of the impurities contained in the substrate can be kept to a minimum. Further, the components contained in the organic film can be recovered at a high recovery rate. Further, by analyzing the recovered organic film by various high-sensitivity analysis methods for analyzing organic substances, it is possible to evaluate the components contained in the organic film with high sensitivity.

前述蒸氣係溶媒被氣化者。該溶媒可為水、酸、鹼、或有機溶媒,亦可為此等之混合物。又,溶媒可為有機膜溶解的溶媒,亦可為雖有機膜剝離但未溶解的溶媒。又,由所謂未使有機膜所含成分之性質變化而回收的觀點,前述溶媒係不分解有機膜的溶媒為較佳。再者,由所謂防止基材所含的雜質溶出的觀點,作為前述溶媒,選擇不溶解或分解基材的溶媒為較佳。 The vapor-based solvent is vaporized. The solvent may be water, an acid, a base, or an organic solvent, or a mixture thereof. Further, the solvent may be a solvent in which the organic film is dissolved, or may be a solvent in which the organic film is peeled off but not dissolved. Moreover, it is preferable that the solvent is a solvent which does not decompose the organic film from the viewpoint that the properties of the components contained in the organic film are not changed. Further, from the viewpoint of preventing elution of impurities contained in the substrate, it is preferred to select a solvent which does not dissolve or decompose the substrate as the solvent.

就有機溶媒而言,例如,可列舉乙腈、氯仿、二氯甲烷、四氫呋喃、己烷、甲苯、甲醇。又,由所謂可將成為分析對象的成分作成水溶性之離子的觀點,溶媒為水較佳。 Examples of the organic solvent include acetonitrile, chloroform, dichloromethane, tetrahydrofuran, hexane, toluene, and methanol. Further, from the viewpoint that the component to be analyzed can be made into a water-soluble ion, the solvent is preferably water.

就酸而言,例如,可列舉氫氟酸、硝酸、鹽酸、硫酸、磷酸、過氧化氫水、及過氯酸。酸可為水溶液,亦可為二種類以上之酸的混合液。溶 液中之酸之濃度係越高越佳,例如,20%以上為較佳,50%以上為更佳,60%以上為特佳。 Examples of the acid include hydrofluoric acid, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid, hydrogen peroxide water, and perchloric acid. The acid may be an aqueous solution or a mixture of two or more kinds of acids. Dissolve The higher the concentration of the acid in the liquid, the better, for example, 20% or more is preferable, 50% or more is more preferable, and 60% or more is particularly preferable.

就鹼而言,例如,可列舉氨、氫氧化鈉、氫氧化鈣、氫氧化四甲銨。鹼可為水溶液,亦可為二種類以上之鹼的混合液。溶液中之鹼之濃度係越高越佳,例如,20%以上為較佳,50%以上為更佳,60%以上為特佳。 Examples of the base include ammonia, sodium hydroxide, calcium hydroxide, and tetramethylammonium hydroxide. The base may be an aqueous solution or a mixture of two or more kinds of bases. The higher the concentration of the alkali in the solution, the better, for example, 20% or more is preferable, 50% or more is more preferable, and 60% or more is particularly preferable.

溶媒之量係只要因應容器的大小或有機膜的量而適宜設定即可。若依據本發明,不論有機膜材料之溶解度為何,皆可回收分析用樣品。據此,與使有機膜浸漬及溶解於液體之溶媒的方法相比,因以少量溶媒即可回收分析用樣品,故可減低來自溶媒的污染。 The amount of the solvent may be appropriately set in accordance with the size of the container or the amount of the organic film. According to the present invention, the sample for analysis can be recovered regardless of the solubility of the organic film material. As a result, compared with the method of immersing and dissolving the organic film in a liquid solvent, the sample for analysis can be recovered with a small amount of solvent, so that contamination from the solvent can be reduced.

於蒸氣接觸步驟,使前述溶媒氣化的蒸氣與有機膜接觸。本發明之回收方法可包含使前述溶媒氣化而使蒸氣發生的蒸氣發生步驟。使蒸氣發生的方法可為溶媒氣化的方法,具體而言,可列舉加熱方法、減壓方法、使超音波振動的方法等。又,可適宜組合此等之方法。 In the vapor contacting step, the vaporized vapor of the solvent is brought into contact with the organic film. The recovery method of the present invention may comprise a vapor generating step of vaporizing the solvent to generate steam. The method of generating the vapor may be a method of vaporizing the solvent, and specific examples thereof include a heating method, a pressure reduction method, and a method of vibrating ultrasonic waves. Further, such methods can be suitably combined.

於加熱的方法,只要用以使有機膜剝離或溶解的充分蒸氣發生,可使溶媒沸騰,亦可不使沸騰。據此,可加熱至溶媒的沸點,亦可加熱至未達沸點的溫度。較佳地,蒸氣為飽和蒸氣。加熱溫度可因應溶媒種類等而適宜決定,但由所謂使蒸氣充分發生的觀點,接近溶媒沸點的溫度為較佳,為溶媒沸點者更佳。例如,溶媒為水的情形,於1氣壓下之加熱溫度係80℃~100℃為較佳,90℃~100℃為更佳,100℃為特佳。若依據本發明,與將有機膜於高溫氧化分解的方法相比,以低溫來處理係可能的。又,加熱時間於例如溶媒為水的情形,5分鐘~120分鐘為較佳,10分鐘~30分鐘為更佳。例如溶媒為乙腈、氯仿、二氯甲烷、四氫呋喃、己烷、甲醇等之低沸點溶媒的情形,3分鐘~60分鐘為較 佳,5分鐘~20分鐘為更佳。例如溶媒為甲苯、硝酸、氫氟酸、硝酸、鹽酸、過氧化氫水、過氯酸、氫氧化鈉水溶液、氫氧化鉀水溶液、氫氧化四甲銨水溶液等之中沸點溶媒的情形,5分鐘~120分鐘為較佳,10分鐘~30分鐘為更佳。例如溶媒為硫酸、磷酸等之高沸點溶媒的情形,10分鐘~120分鐘為較佳,20分鐘~60分鐘為更佳。若為該加熱時間,由所謂使充分產生蒸氣的觀點為較佳。 In the heating method, as long as sufficient vapor for separating or dissolving the organic film occurs, the solvent may be boiled or boiled. Accordingly, it can be heated to the boiling point of the solvent, or heated to a temperature at which the boiling point is not reached. Preferably, the vapor is a saturated vapor. The heating temperature can be appropriately determined depending on the type of the solvent, etc., but the temperature near the boiling point of the solvent is preferably from the viewpoint of sufficiently generating the vapor, and the boiling point of the solvent is more preferable. For example, in the case where the solvent is water, the heating temperature at 1 atmosphere is preferably 80 ° C to 100 ° C, more preferably 90 ° C to 100 ° C, and 100 ° C is particularly preferable. According to the present invention, it is possible to treat at a low temperature as compared with a method of oxidative decomposition of an organic film at a high temperature. Further, the heating time is, for example, a case where the solvent is water, preferably 5 minutes to 120 minutes, more preferably 10 minutes to 30 minutes. For example, when the solvent is a low-boiling solvent such as acetonitrile, chloroform, dichloromethane, tetrahydrofuran, hexane or methanol, the temperature is from 3 minutes to 60 minutes. Good, 5 minutes to 20 minutes is better. For example, the solvent is a solvent such as toluene, nitric acid, hydrofluoric acid, nitric acid, hydrochloric acid, hydrogen peroxide water, perchloric acid, aqueous sodium hydroxide solution, potassium hydroxide aqueous solution or tetramethylammonium hydroxide aqueous solution, and 5 minutes. ~120 minutes is better, and 10 minutes to 30 minutes is better. For example, in the case where the solvent is a high-boiling solvent such as sulfuric acid or phosphoric acid, it is preferably from 10 minutes to 120 minutes, more preferably from 20 minutes to 60 minutes. In the case of this heating time, it is preferable from the viewpoint of sufficiently generating vapor.

關於減壓的方法,只要至蒸氣產生的壓力為止的減壓即可。 The method of reducing the pressure may be a pressure reduction until the pressure generated by the vapor.

有機膜可直接保持膜之形狀而自基材剝離被回收,亦可以一部分或全部被溶解的狀態下被回收。例如,蒸氣浸透有機膜而到達有機膜與基材的界面,藉由減弱有機膜與基材之結合,亦可使有機膜被剝離。又,可為有機膜之表面被緩緩地溶解。有機膜係由複數層所構成的情形,可一層層地被剝離而被回收。 The organic film can be directly removed from the substrate by being held in the shape of the film, or can be recovered in a state in which some or all of it is dissolved. For example, the vapor penetrates the organic film to reach the interface between the organic film and the substrate, and the organic film can be peeled off by weakening the bonding between the organic film and the substrate. Further, the surface of the organic film may be slowly dissolved. When the organic film is composed of a plurality of layers, it can be peeled off and recovered in layers.

被溶解的有機膜可與溶媒一起被回收。被剝離的有機膜亦可與溶媒一起被回收,或者,與溶媒分離,具體而言,基板上殘留的具有膜狀的有機物可被回收。據此,溶媒可兼作有機膜之回收液的機能。本發明之回收方法亦可謂包含回收來自有機膜的成分作為分析用樣品的回收步驟。 The dissolved organic film can be recovered together with the solvent. The peeled organic film may be recovered together with the solvent or may be separated from the solvent, and specifically, the organic substance having a film shape remaining on the substrate may be recovered. Accordingly, the solvent can serve as a function of the recovery liquid of the organic film. The recovery method of the present invention may also be a recovery step including recovering a component derived from an organic film as a sample for analysis.

再者,藉由變更溶媒的種類,以含有成為分析對象的成分的揮發性之元素的回收、或該成分之形態類別(固體、液體、氣體)之回收為可能的。又,亦可將成為分析對象的成分所含的元素以離子的形態來回收。又,藉由選擇溶媒的種類,可減少操作過程的空白(blank)。 Further, by changing the type of the solvent, it is possible to recover the volatile element containing the component to be analyzed or to recover the form type (solid, liquid, gas) of the component. Further, the element contained in the component to be analyzed may be recovered in the form of ions. Further, by selecting the type of the solvent, the blank of the operation process can be reduced.

使蒸氣接觸的時間係因應溶媒的種類或蒸氣壓、有機膜的大小等,而適宜設定即可。由所謂使有機膜充分剝離或溶解的觀點,例如,使蒸氣接觸的時間係30分鐘~60分鐘為較佳,60分鐘~180分鐘為更佳,180分鐘~480 分鐘為特佳。 The time for bringing the vapor into contact may be appropriately set depending on the type of the solvent, the vapor pressure, the size of the organic film, and the like. From the viewpoint of sufficiently peeling or dissolving the organic film, for example, the time for bringing the vapor into contact is preferably 30 minutes to 60 minutes, more preferably 60 minutes to 180 minutes, and 180 minutes to 480 minutes. Minutes are especially good.

於本發明之回收方法,使有機膜與蒸氣接觸的同時,可將有機膜及/或有機膜所形成的基材加熱或冷卻。 In the recovery method of the present invention, the organic film and/or the substrate formed of the organic film may be heated or cooled while the organic film is in contact with the vapor.

又,藉由變更使蒸氣產生時之溫度或時間等之條件,例如可使有機膜之剝離強度變化。因此,具有可應用於有機膜所含成分之於深度方向(有機膜之厚度方向)之評價的可能性。據此,藉由調節剝離強度,可僅回收有機膜之厚度方向之一部分區域。據此,可選擇性地回收有機膜之厚度方向之任意區域。因此,可於有機膜之厚度方向作階段性地分析。據此,例如,可區別有機膜之表面所存在的成分之含量、及基材與有機膜之界面附近區域存在的成分之含量而加以分析。 Further, by changing the conditions such as the temperature or time at which the vapor is generated, for example, the peeling strength of the organic film can be changed. Therefore, there is a possibility that it can be applied to the evaluation of the components contained in the organic film in the depth direction (the thickness direction of the organic film). According to this, by adjusting the peeling strength, only a part of the thickness direction of the organic film can be recovered. According to this, any region in the thickness direction of the organic film can be selectively recovered. Therefore, it can be analyzed stepwise in the thickness direction of the organic film. According to this, for example, the content of the component present on the surface of the organic film and the content of the component existing in the vicinity of the interface between the substrate and the organic film can be analyzed.

因此,上述之有機膜之表面所存在的成分、及基材與有機膜之界面附近區域所存在的成分亦包含於成為本發明所致的回收對象及/或分析對象的成分(換言之,包含於有機膜的成分)。又,於本說明書,有機膜之表面所存在的成分係意指於有機膜之內部且為有機膜之表面附近的區域存在的成分及附著於有機膜之表面的成分。於有機膜之內部且為有機膜之表面附近區域係指例如,可為自有機膜之表面面向內部朝厚度方向10nm以內的區域,亦可為朝厚度方向1nm以內之區域,亦可為朝厚度方向0.1nm以內的區域。 Therefore, the component present on the surface of the organic film and the component existing in the vicinity of the interface between the substrate and the organic film are also included in the component to be recovered and/or analyzed by the present invention (in other words, included in The composition of the organic film). Moreover, in the present specification, the component existing on the surface of the organic film means a component existing inside the organic film and present in a region near the surface of the organic film, and a component adhering to the surface of the organic film. The region in the vicinity of the surface of the organic film and the surface of the organic film may be, for example, a region within 10 nm from the surface of the organic film facing the inside in the thickness direction, or a region within 1 nm in the thickness direction, or may be a thickness toward the thickness. The area within 0.1 nm direction.

使蒸氣接觸的方向亦未特別限定。將有機膜所形成的基材配置於容器內,藉由於該容器內使蒸氣產生,容器內以蒸氣填滿,可使有機膜與蒸氣接觸。又,藉由噴灑含蒸氣的氣體,可自冀望的方向使蒸氣接觸。 The direction in which the vapor is brought into contact is also not particularly limited. The substrate formed of the organic film is placed in a container, and the vapor is generated in the container, and the inside of the container is filled with steam to bring the organic film into contact with the vapor. Further, by spraying a gas containing steam, the vapor can be brought into contact in a direction in which it is viewed.

前述蒸氣接觸步驟係於密閉容器內進行者較佳。於此情形,於成為分析之對象的成分具有揮發性的情形,亦可減少回收的損失。密閉容器係 只要可防止分析對象成分向容器外側環境的揮發的容器即可,並未特別限定。亦可使用具有開口部的容器,藉由基材上之有機膜所形成的面將開口部封閉而作成密閉容器。又,於密閉容器內進行前述接觸步驟的情形,亦可防止來自操作環境的污染。 It is preferred that the vapor contacting step be carried out in a closed container. In this case, in the case where the component to be analyzed is volatile, the loss of recovery can also be reduced. Closed container The container is not particularly limited as long as it can prevent the analyte component from volatilizing into the environment outside the container. A container having an opening may be used, and the opening may be closed by a surface formed by the organic film on the substrate to form a sealed container. Further, in the case where the above-described contacting step is carried out in a sealed container, contamination from the operating environment can be prevented.

以下說明於容器內使蒸氣產生的方法之一例。首先,將對應成為回收對象的有機膜之材質的溶媒置入容器中。置入溶媒的容器係只要以具備對該溶媒有耐性(不會經溶媒而被溶解)的材質所形成者即可。具體而言,只要為以氟樹脂、石英等所形成的容器,即可不污染被回收的分析用樣品而為較佳。就氟樹脂而言,例如,可列舉聚四氟乙烯(PTFE)、四氟乙烯‧全氟烷基乙烯醚共聚物(PFA)、聚偏二氟乙烯(polyvinylidene fluoride,PVDF)、聚氯三氟乙烯(polychlorotrifluoroethylene,PCTFE)。 An example of a method of generating steam in a container will be described below. First, a solvent corresponding to the material of the organic film to be collected is placed in a container. The container in which the solvent is placed may be formed of a material having resistance to the solvent (not dissolved by the solvent). Specifically, as long as it is a container formed of a fluororesin, quartz or the like, it is preferable to not contaminate the sample for analysis to be recovered. Examples of the fluororesin include polytetrafluoroethylene (PTFE), tetrafluoroethylene, perfluoroalkyl vinyl ether copolymer (PFA), polyvinylidene fluoride (PVDF), and polychlorotrifluorocarbon. Polychlorotrifluoroethylene (PCTFE).

其次,於置入溶媒的容器中,配置有機膜所形成的基材。該基材只要安置使有機膜不與液體狀的溶媒(氣化前之溶媒)接觸的位置即可。而,藉由將容器加熱,或藉由於容器內使減壓或超音波振動而產生蒸氣,使有機膜與蒸氣接觸即可。 Next, a substrate formed of an organic film is placed in a container in which a solvent is placed. The substrate may be disposed so that the organic film does not come into contact with a liquid solvent (solvent before vaporization). Further, the organic film may be brought into contact with the vapor by heating the container or by generating a vapor by decompression or ultrasonic vibration in the container.

例如,可使有機膜所形成的面向下的方式來配置基材,使自下側與蒸氣接觸。又,可使有機膜所形成的面向上的方式來配置基材,使自上側與蒸氣接觸。又,其中,「下」係意指重力方向,「上」意指與重力方向相反的方向。又,亦可配置機材使有機膜所形成的面朝向與重力方向垂直的方向,而使與蒸氣接觸。 For example, the substrate may be disposed in a downwardly facing manner in which the organic film is formed so as to be in contact with the vapor from the lower side. Further, the substrate may be placed in such a manner that the organic film is formed to face upward, and the upper side is brought into contact with the vapor. In addition, "lower" means the direction of gravity, and "upper" means the direction opposite to the direction of gravity. Further, the machine may be arranged such that the surface formed by the organic film faces the direction perpendicular to the direction of gravity and comes into contact with the vapor.

設置基材使有機膜所形成的面向下,使自下側與蒸氣接觸的情形,亦可藉由使有機膜(或有機膜之溶解物)藉由本身重量而向重力方向落下而加 以回收。又,此情形,若將成為蒸氣之產生源的溶媒配置於下側,可使被剝離的有機膜(或有機膜之溶解物)落下至溶媒中而回收。 The substrate is disposed such that the surface formed by the organic film faces downward, and the contact with the vapor from the lower side can also be caused by causing the organic film (or the dissolved material of the organic film) to fall in the direction of gravity by its own weight. To recycle. In this case, when the solvent serving as the source of the vapor is disposed on the lower side, the peeled organic film (or the dissolved product of the organic film) can be dropped into the solvent and recovered.

又,藉由調整有機膜之與蒸氣接觸的面積,可僅使蒸氣與前述有機膜之一部分區域接觸。據此,可選擇性地回收有機膜之任意區域。據此,可選擇性地分析來自有機膜之任意區域的成分。例如,藉由遮蔽成為分析對象的任意區域以外的區域後,使與蒸氣接觸,亦可調整使有機膜之與蒸氣接觸的面積。 Further, by adjusting the area of the organic film in contact with the vapor, only the vapor can be brought into contact with a partial region of the organic film. According to this, any region of the organic film can be selectively recovered. According to this, the composition from any region of the organic film can be selectively analyzed. For example, by shielding the region other than the arbitrary region to be analyzed, the surface of the organic film in contact with the vapor can be adjusted by bringing it into contact with the vapor.

若藉由與本發明有關的分析用樣品之回收方法,因使用蒸氣,藉由調節蒸氣之接觸面積及接觸強度,可回收有機膜全體,亦可回收有機膜之一部分區域。藉由本發明之回收方法所回收的分析用樣品可使用於可評價有機膜全體的分析方法。又,若依據本發明之回收方法,例如與各基板以高溫將有機膜氧化分解的方法相比,選擇性回收有機膜中之任意區域為容易的。 According to the method for recovering an analysis sample according to the present invention, by using steam, by adjusting the contact area and contact strength of the vapor, the entire organic film can be recovered, and a part of the organic film can be recovered. The sample for analysis recovered by the recovery method of the present invention can be used for an analytical method for evaluating the entire organic film. Further, according to the recovery method of the present invention, for example, it is easy to selectively recover any region in the organic film as compared with a method in which each substrate oxidizes and decomposes the organic film at a high temperature.

藉由將有機膜剝離或溶解而被回收的分析用樣品中可包含成為分析對象的成分。檢測前述檢測步驟中的成分的方法係因應回收的有機膜之形態(膜狀或液體狀)及成為分析對象的成分之種類,而選擇適當方法即可。 The sample for analysis which is recovered by peeling or dissolving the organic film may contain a component to be analyzed. The method of detecting the components in the detection step may be an appropriate method depending on the form (membrane or liquid) of the organic film to be recovered and the type of the component to be analyzed.

例如,就於檢測步驟所使用的方法而言,可列舉感應耦合電漿質譜儀分析法(inductively coupled plasma-mass spectrometer,ICP-MS)、感應耦合電漿原子放射光譜儀分析法(inductively coupled plasma atomic emission spectrometer,ICP-AES)、原子吸光分析法(atomic absorption spectrometer,AAS)、 離子層析法(ion chromatography)、毛細管電泳法(capillary electrophoresis)、液體層析法(liquid chromatography)、氣體層析法(gas chromatography)。此等之方法因與例如直接分析法(XPS、XRD、TXRF、TOF-SIMS、SIMS、GD-OES等)相比,測定敏感度良好而為較佳。 For example, in terms of the method used in the detection step, an inductively coupled plasma-mass spectrometer (ICP-MS) or an inductively coupled plasma atomic spectrometer can be cited.
