(發明說明應敘明:發明所屬之技術領域、先前技術、內容、實施方式及圖式簡單說明) (一) 發明所屬之技術領域 本發明是關於一種洗淨裝置,詳言之,係關於一種用 於製造電路用基板之方法中,用於將經以處理液加以表面 處理過之基板材料用洗淨液加以洗淨的洗淨裝置。 (二) 先前技術 技術背景 φ 隨著電子機器之高性能化、高功能化、小型輕量化, 其電路用基板也朝高精確度化、精巧化、極薄化方向邁進, 1 使得所形成的電路之高密度化、微小化非常顯著。並且在 ’ 此種基板之製程,則在各程序中對於輸送中之基板材料噴 射處理液,藉以對基板材料施加各種表面處理。 例如,一向是依序噴射顯影液—蝕刻液—剝離液等處 理液,藉以依序施加顯影—飩刻-剝離等處理而形成電路。 另一方面一向是例如依序施加浸漬於非電解鑛銅液—噴射 φ 顯影液—浸漬於電解鍍銅液Θ噴射剝離液等,藉以依序施 加化學式鍍銅—顯影—電鍍銅Θ剝離等處理而形成電路。 並且一向是噴射水洗液等洗淨液以作爲該等程序之事 後處理而實施洗淨處理。 如上所述,在基板之製程,例如最近之等離子體顯示 器用或液晶用玻璃基板之製程、或經封裝有半導體零組件 的模組基板之製程、以及其他之印刷配線基板之製程中, 一 6 - 565473 則在其各程序爲了形成電路而經用酸性或鹼性處理液施加 基板材料之表面處理後,實施使用洗淨液的洗淨處理以作 爲事後處理,藉以實行經表面處理後附著、殘留於基板材 料的處理液之洗淨除去工作。 並且如此之洗淨處理,對於如上所述電路之高密度化、 微小化正在不斷地進展的此種基板而言,在其品質上之重 要性日益增加。 換句話說,若不能確實實施事後之洗淨處理,則將在 其後續程序發生障礙、造成氧化之原因,致有可能在半導 體零組件組配上招致障礙。 <以往之技術> 以往,如此之基板材料的洗淨處理,一向是使用洗淨 噴嘴與空氣噴嘴來進行。 換句話說,此種傳統洗淨處理一向是採取如下述步驟 即:邊以輸送機輸送基板材料下,θ邊由前後左右相對配 置之眾多洗淨噴嘴,噴射水洗液或其他洗淨液,—而將基 板材料加以洗淨處理後’—由相對配置之空氣噴嘴噴射空 氣,-> 藉以由基板材料上除去經由洗淨噴嘴噴射而滯留於 基板材料上之洗淨液。 欲解決之課題 ' <關於第一問題> 然而此種傳統洗淨裝置’ 一直有如下述問題爲人所詬 病0 -7 - 565473 第一,受到指摘之問題爲無法確實除去洗淨液。即經 由洗淨噴嘴噴出之洗淨液,其大部分雖會一面洗淨基板一 面流向基板材料左右(與輸送方向成正交之寬度方向)後, 由左右側端流下而落下,但有一部分仍舊會滯留於基板上。 在藉由洗淨噴嘴之洗淨處理結束時,基板上仍然滯留 著厚度達數毫米左右之末流下的洗淨液,並且如此般滯留 之洗淨液,雖然寄望於後續程序之藉空氣噴嘴的空氣吹刮 來加以除去,但是以往其除去效果卻非確實。 按對於厚度達數毫米之洗淨液而言,僅靠空氣噴嘴的 吹刮,則因其沖力弱,所以仍難於除去其全部。 尤其在最近之玻璃基板有工件大小趨於大片化之傾向 下,洗淨液會在大的基板上滯留成廣大又厚的積水狀,使 得確實的除去更加有困難。加上也會發生因空氣吹刮而由 基板飛散飄浮之洗淨液,會再度附著於基板上之現象。 如此在已通過空氣噴嘴段之基板上,會有洗淨液之水 滴殘留,或起因於該水滴並隨著時間經過而發生斑點或污 點等情事。如此之水滴或斑點•污點等,必會在後續程序 中招致各種障礙,造成電路之氧化或侵蝕等原因,且對於 半導體零組件之裝配也會引起故障等各種電路事故。 如前所述,對於電路之高密度化、微小化正在急速進 展的此種基板而言,如此之事故發生,將造成品質上的致 命傷。 <關於第二之問題> 一 8 - 565473 第二,在設備成本或維護方面,也有問題受到指摘。 即以往也採取將空氣噴嘴設成爲複數段,以作爲上述洗淨 液滯留現象之因應對策。 然因此種空氣噴嘴卻由於爲使空氣能均勻噴射而要求 非常高的精確度,以致價格貴到一支單價爲例如達幾拾萬 曰元之鉅,因此如欲使用複數支空氣噴嘴,則在設備成本 方面大有問題。加上需要大容量空氣壓縮機等來配合供應 大量空氣,致使在動力成本、維護成本、運轉成本方面也 有問題受到指摘。 (三)發明內容 <關於本發明> 有鑑於此,本發明之洗淨裝置是爲解決上述傳統方式 之課題而經由本發明者專心致力於硏發結果所完成者。 其特徵爲在洗淨噴嘴與空氣噴嘴之間配置逆向噴嘴而 朝向上游側噴射洗淨液,藉以推回滯留於基板上的洗淨液 而構成者。 因此本發明之目的在於提供一種基板之製造工程用之 洗淨裝置,其係可由基板材料上確實除去洗淨液,及該洗 淨裝置是在設備成本或運轉成本方面優越且可付諸實務應 用的洗淨裝置。 [解決問題之技術方法] <關於各申請專利範圍請求項> 能解決如上所述課題的本發明之技術手段如下。首先 關於請求項1如下。請求項1之洗淨裝置,其特徵爲:是 -9- 565473 用於基板之製程,且對於以輸送機輸送之基板材料依序設 有噴射洗淨液之洗淨噴嘴,向上游側噴射流體之逆向噴嘴, 以及噴射空氣之空氣噴嘴。 關於請求項2如下。請求項2之洗淨裝置,其特徵爲: 是在請求項1中用以使用洗淨液來洗淨爲了形成電路而經 用處理液加以表面處理之該基板材料者。且自上游側向下 游側依序設有該洗淨噴嘴與該逆向噴嘴與該空氣噴嘴。 並且,該輸送機具有滾輪群或輪子群,用以以水平姿 勢輸送該基板材料。該洗淨噴嘴是相對於被輸送之該基板 材料,在前後左右相對配置有複數個,用以噴射水洗液或 其他洗淨液。 該逆向噴嘴是對於被輸送之該基板材料,向與輸送方 向相反之上游側傾斜而相對配置,用以噴射水洗液或其他 之洗淨液。該空氣噴嘴是對於被輸送之該基板材料相對而 配置。 關於請求項3如下。請求項3之洗淨裝置,其特徵爲: 在請求項3中該逆向噴嘴是對於被輸送之該基板材料以掩 蓋其全幅寬範圍之方式而配置,用以對該基板材料使洗淨 液向上游側斜成下降傾斜而噴射成幕狀。 並且藉如此之洗淨液噴射,即能發揮使經由該洗淨噴 嘴噴射而滯留於該基板材料上之洗淨液向上游側推回之功 能而使洗淨液由該基板材料之左右兩側端流下。 關於請求項4如下。請求項4之洗淨裝置,其特徵爲: 在請求項3中該空氣噴嘴是對於被輸送之該基板材料以掩 - 1 0 - 565473 蓋其全幅寬範圍之方式相對而配置,且由向左右之寬度方 向呈直線的縫隙狀噴嘴所構成,同時向上游側傾斜而相對 配置’用以對該基板材料使空氣向上游側傾斜而噴射成幕 狀。 並且藉如此之空氣噴射使經以該逆向噴嘴或因自然落 下而除去大部分所剩下之洗淨液,由該基板材料加以除去。 關於請求項5如下。該請求項5之洗淨裝置,其特徵 爲:在請求項4中該洗淨噴嘴是至少配置在被輸送之該基 板材料之上側,且介以配管連接於泵或液槽。該逆向噴嘴 是至少配置在被輸送之該基板材料之上側,且介以配管連 接於栗或液槽。該空氣噴嘴是至少配置在被輸送之該基板 材料之上側’且介以配管而連接於空氣源。 關於請求項6如下。請求項6之洗淨裝置,其特徵爲: 在請求項5中該洗淨裝置是用於等離子體顯示器用或液晶 用之玻璃基板、封裝有半導體零組件之模組基板、及其他 印刷配線基板之製程。 關於請求項7如下。請求項7之洗淨裝置,其特徵爲: 在請求項6中該洗淨裝置是用於處理程序之預先處理或事 後處理’用以除去在該基板材料所附著、殘留之處理液及 其他。 <關於作用> 本發明由於構成如上所述,具有如下列作用。 565473 該洗淨裝置可用於等離子體顯示器或液晶用玻璃基 板、或經封裝有半導體零組件之模組基板、及其他印刷配 線基板之製程。 並且基板材料是在例如顯影程序、蝕刻程序、剝離程 序等之前段程序中爲形成電路而用處理液受到表面處理。 然後基板材料將在事後處理用之洗淨裝置中,用洗淨 液加以洗淨、除去所附著、殘留之處理液。另外該洗淨裝 置不僅是可作爲如此之處理程序的事後處理用,也有作爲 處理程序之預先處理用而使用之情況,此種情況下,則爲 了準備處理程序,先用洗淨液將附著於基板材料之微小塵 埃、或其他加以洗淨、除去。 並且,基板材料是用輸送機以水平姿勢下輸送,並使 之依序通過洗淨噴嘴、逆向噴嘴、空氣噴嘴。 洗淨噴嘴是至少在基板材料之上側相對配置成複數 個,且連接於泵或液槽,用以對基板材料噴射水洗液或其 他洗淨液,而洗淨、除去所附著、殘留的處理液及其他。 此外由上側洗淨噴嘴噴射之洗淨液,經洗淨處理後, 其大部分是在基板材料上面流向左右而由左右側端落下。 與此相對,由下側洗淨噴嘴噴射之洗淨液,經洗淨處理後, 則幾乎是全部由基板材料下面自然落下。 逆向噴嘴是在基板材料上側向上游側傾斜而相對配 置,且連接於泵或液槽,用以對基板材料上面使洗淨液等 向上游側斜成下降傾斜而噴射成幕狀。 565473 按經由洗淨噴嘴噴射於基板材料上面之洗淨液,雖有 部分會滯留於基板材料上面,但該洗淨液將藉經由如此之 逆向噴嘴所噴出之強沖力的洗淨液等,使其大部分向上游 側推回後,由基板材料之左右側端落下。 空氣噴嘴是由至少在基板材料上側,向上游側傾斜而 相對配置且由向寬度方向呈直線的縫隙狀噴嘴構成,同時 連接於空氣壓縮機等空氣源,用以對該基板材料使空氣向 上游側傾斜而噴射成幕狀。 基板材料之上面或下面,經藉逆向噴嘴或因自然落下 而只不過是只有少許洗淨液殘留成薄膜狀而已,惟藉來自 於如此之空氣噴嘴的空氣即能將之加以除盡。 該洗淨裝置,是在洗淨噴嘴與空氣噴嘴之間設有連接 於泵或液槽的逆向噴嘴之簡單結構所構成。 (四)實施方式 <關於圖式> 茲根據圖式所示發明之實施方式將本發明詳加說明如 下。第1圖、第2圖、第3圖是用以說明本發明之實施方 式。其中第1圖是側剖面說明圖。第2圖是平面說明圖。 第3圖之(1 )圖是孔狀嘴之底面說明圖、(2 )圖是縫隙狀噴 嘴之底面說明圖,(3 )圖是印刷配線基板(基板材料)之平面 說明圖。 <關於基板B> 該洗淨裝置1是供使用於電路A用的基板B之製程。 因此先就此種基板B之槪要說明如下(請參閱第3圖(B))。 - 13- 565473 電路A用之基板係廣泛被使用於各種電子機器用,其 型式有單面基板、雙面基板、多層基板(包括最近之沉積 (bu i 1 d - up )法者)等各種。並且作爲如此基板b的一環而 也有出現使1C (積體電路)、LSI (大型積體電路)元件、 被動元件、驅動元件、電容器等半導體構件,與電路A搭 配成一體的模組基板(半導體封裝基板),或在玻璃基質與 電路A —起埋設有半導體構件之玻璃基板,即等離子體顯 示器PDP (等離子體顯示面板)用之玻璃基板,或液晶LCD 用玻璃基板,或晶片型封裝(CSP ),塑膠球型柵狀陣列基板 PBGA等。當然本案專利說明書中所提及基板B,除先前之 印刷配線基板外,也包含此種各基板。 按如此之電路A用之基板B,是隨著電子機器之高性 能化、高功能化、小型輕量化而不斷地往高精確度化、精 巧化、極薄化、多層化等前進,使得形成於外表面,即上 面•表面或下面•背面之單面或雙面之電路A,甚至於形成 於內部的電路A之高密度化、微小化非常顯著。 基板B例如印刷配線基板,其縱橫是由例如500毫米 X 5 00毫米左右構成,厚度是絕緣層部分爲1 . 〇毫米〜60 微米,電路A部分爲75微米〜35微米,惟最近則已極薄 化至25微米〜10微米左右。多層基板之情形時,全體厚 度也正在極薄化至1.0毫米〜0.4毫米左右。電路A之線 條寬或電路A之線間寬爲35微米〜25微米左右,也有微 小化傾向。 基板B是槪略具有如上所述構成。 -14- 565473 <關於基板B之製造方法實例> fe者就使用該洗淨裝置1的基板B之製造方法說明如 下。首先就其第一實例之製造方法加以說明。在第一實例 製造方法中,基板B之第一實例的印刷配線基板是經過下 述過程而製造。 首先準備襯銅疊層板之基板材料C,該襯銅疊層板是 在樹脂、玻璃布或陶瓷製之絕緣層(芯材料)外表面,以’ 熱壓接機等貼上銅箔而成者。然後以雷射等方法實施通孔 (throughhole)用之穿孔加工。 · 通孔是由基板材料C (基板B)之兩外表面間之穿通孔 · 構成’每一片形成有數百個以上之屬極小徑者,其徑是以 0.5亳米〜0.2毫米左右以下者爲多。通孔是供連接兩外表 面間或多層基板之電路A間之用,或供安裝於電路A的零 組件之裝配用。 按最近也開發出 NMBI [Neo-Manhattan Bump Interconnection(尼爾-曼哈頓(音譯)焊墊內連接)]法。該 _ NMBI是一種替代通孔而使用小突起狀的焊墊(bump ),而以 無須穿孔加工方式藉由焊墊來實現與通孔同等功能之技術。 然後在基板材料C之銅箔外表面(上面•表面、下面· 背面中之單面或雙面),以膜狀將光敏抗蝕劑塗敷或貼付在 一起。接著放上描繪有電路A之負片的電路照片,經由曝 光,使外表面之光敏抗蝕劑留下被曝光而硬化的電路A形 成部分,其他之不需要部分則以噴射顯影液而予以溶解除 去。 -15 - 565473 接著如此之基板材料c的銅箔,會留下爲光敏抗蝕劑 經硬化所被覆之電路A形成部分,光敏抗鈾劑經顯影處理 而被溶解除去之不需要部分則藉噴射蝕刻液(氯化銅(Π )、 氧化鐵(ΠΙ ))之溶解除去作用來加以蝕刻。 接著所殘留之電路A形成部分,則藉噴射剝離液來加 以剝離除去,俾由剩下之電路A形成部分的銅箔,在基板 材料C之外表面(上面•表面、下面•背面之單面或雙面) 形成預定之電路A,如此便可製得基板B,即印刷配線基板。 並且在上述顯影程序、蝕刻程序、剝離程序,爲了各 自之事後處理用、或剝離程序後匯集作事後處理用,附設 有用以噴射水洗液、中和劑液及其他洗淨噴嘴之洗淨程序, 俾以洗淨除去附著於基板材料C外表面之顯影液、蝕刻液、 剝離液等處理液。第一實例之製造方法是由如此之濕式法 構成。 弟一貫例之製造方法是如上所述。 接著就第二實例之製造方法說明如下。基板B之一實 例的印刷配線基板之製造方法,是以上述第一實例之濕式 法爲其主流’但第一貫例之半附加法也正在受到大多數的 使用。 該半附加法是首先在預先形成有通孔之基板材料C的 外表面(上面•表面、下面•背面中之單面或雙面)形成 非電解鍍銅膜。—然後以膜狀將光敏抗蝕劑塗敷或貼付在 該非電解鍍銅膜後,—放上描繪有電路A之負片的電路照 片’進行曝光。—因而光敏抗蝕劑就留下被曝光而硬化的 565473 部分,其他部分,即電路A形成部分則藉噴射顯影液而予 以溶解除去。 然後—對於電路A形成部分,即光敏抗蝕劑藉顯影處 理而被溶解除去的電鍍膜圖案部分,亦即非電解鍍銅膜露 出的部分,施加電解鍍銅,—藉以形成電路A。 另外己硬化的電路A形成部分以外之剩下的光敏抗蝕 劑,將藉噴射剝離液而加以剝膜除去,^露出的非電解鍍 銅膜就藉蝕刻液之噴射,受到快速蝕刻而被融解除去。-> 此外按照前述方式也附加有洗淨程序以作爲各程序之事後 處理用。 第二實例之半附加法是以如此方式藉電解鍍銅形成電 路A,藉以製造基板B,即印刷配線基板。第二實例是構成 爲如上所述。 然而印刷配線基板之製造方法及其他電路A用之基板 B之製造方法,最近正在日益更趨於多樣化,除上述第一 實例、第二實例外,也有曾硏發出各種方法而使用。本發 明當然也能適用於如此之各種印刷配線基板及其他基板B 之製造方法。 基板B之製造方法是如上所述構成。 <關於洗淨裝置1之槪要> 以下參照第1圖至第3圖就洗淨裝置1說明如下。該 洗淨裝置1是在上述基板B之製程,用以爲了形成電路A 而經用處理液D施加表面處理之基板材料C,用洗淨液加 以洗淨。 -

(The description of the invention should be stated (A brief description of the technical field, prior art, content, embodiments, and drawings of the invention) (1) The technical field of the invention The present invention relates to a cleaning device, and in particular, it relates to a substrate for manufacturing a circuit In this method, a cleaning device for cleaning a substrate material that has been surface-treated with a processing liquid with a cleaning liquid. (II) Prior technical background φ With the high performance, high functionality, small size and light weight of electronic devices, the circuit substrates are also moving towards high precision, compactness, and ultra-thinness. 1 makes the The density and miniaturization of the circuit are very significant. And in the process of such a substrate, the substrate liquid is sprayed with a processing liquid in each procedure to apply various surface treatments to the substrate material. For example, a processing solution such as a developing solution, an etching solution, and a stripping solution is sequentially sprayed, and a process such as development, engraving, and stripping is sequentially applied to form a circuit. On the other hand, for example, sequential application of immersion in non-electrolytic copper liquid-jet φ developing solution-immersion in electrolytic copper plating solution Θ spray stripping, etc., in order to sequentially apply chemical copper plating-development-electroplating copper Θ peeling and other treatments And form a circuit. In addition, a washing liquid such as a water washing liquid is sprayed as a post-processing of such procedures to perform a washing treatment. As described above, in the manufacturing process of the substrate, such as the recent manufacturing process of the glass substrate for plasma display or liquid crystal, the manufacturing process of the module substrate packaged with semiconductor components, and the manufacturing process of other printed wiring boards, -565473 After the surface treatment of the substrate material with an acidic or alkaline treatment liquid is applied to each of its procedures to form a circuit, a cleaning treatment using a cleaning solution is performed as an after-treatment, so that adhesion and residue after surface treatment are implemented. Cleaning and removal of the processing liquid on the substrate material. In addition, such a cleaning process is increasingly important in terms of quality for such substrates where the density and miniaturization of circuits are continuously progressing as described above. In other words, if the subsequent cleaning treatment cannot be carried out, it will cause obstacles in its subsequent procedures and cause oxidation, which may cause obstacles in the assembly of semiconductor components. < Conventional technology > Conventionally, such a substrate material cleaning process has been performed using a cleaning nozzle and an air nozzle. In other words, this traditional cleaning process has always taken the following steps: while conveying the substrate material by a conveyor, θ, spraying water washing liquid or other washing liquid from a large number of washing nozzles arranged front, back, left and right,- After the substrate material is cleaned, the air is sprayed from the oppositely disposed air nozzles, and the cleaning liquid remaining on the substrate material is ejected from the substrate material through the cleaning nozzle. Issues to be solved '' < About the first problem > However, such a conventional cleaning device 'has always been criticized as follows: 0 -7-565473 First, the problem of being criticized is that the cleaning solution cannot be removed reliably. That is, most of the cleaning liquid sprayed from the cleaning nozzle flows to the left and right of the substrate material (the width direction orthogonal to the conveying direction) while washing the substrate, and then flows down from the left and right ends, but some remain. Will stay on the substrate. At the end of the cleaning process by the cleaning nozzle, the cleaning liquid flowing down at the end of the thickness of about several millimeters is still retained on the substrate, and the cleaning liquid retained in such a manner, although it is hoped that the air nozzle will be used in the subsequent process The air is blown to remove it, but its removal effect is not sure in the past. For a cleaning liquid having a thickness of several millimeters, it is difficult to remove all of the cleaning liquid only by blowing with an air nozzle because of its impulse. Especially in recent glass substrates, which tend to become larger in size, the cleaning solution will stay on the large substrate into a large and thick stagnant water, making it more difficult to remove it with certainty. In addition, the floating cleaning liquid scattered from the substrate due to air blowing may reattach to the substrate. In this way, on the substrate that has passed through the air nozzle section, water droplets of the cleaning solution may remain, or due to the water droplets, spots or stains may occur over time. Such water droplets, spots, and stains will inevitably cause various obstacles in the subsequent procedures, resulting in oxidation or erosion of the circuit, and various circuit accidents such as failure in the assembly of semiconductor components. As mentioned above, for such substrates where the density and miniaturization of circuits are rapidly progressing, such an accident will cause fatal injuries in quality. < Question about the second issue > Ⅰ 8-565473 Second, there are also problems that have been criticized in terms of equipment cost or maintenance. That is, in the past, the air nozzles have been provided in a plurality of stages as a countermeasure against the above-mentioned washing liquid retention phenomenon. However, because this kind of air nozzle requires very high accuracy in order to make the air spray uniformly, the price is so expensive that a unit price is, for example, hundreds of thousands of dollars, so if you want to use multiple air nozzles, There are major problems in terms of equipment costs. In addition, the need for large-capacity air compressors to supply a large amount of air has led to criticisms of problems in power costs, maintenance costs, and operating costs. (III) Content of the invention < About the present invention > In view of this, the cleaning device of the present invention has been completed by the present inventor with dedicated efforts to solve the problems of the conventional method described above.

The process. Request item 7 is as follows. The cleaning device of claim 7 is characterized in that: the cleaning device of claim 6 is used for pre-processing or post-processing of a processing program 'to remove the processing liquid and other residues attached to the substrate material. < Regarding effects > Since the present invention is constituted as described above, it has the following effects. 565473 This cleaning device can be used in the manufacturing process of plasma display or glass substrate for liquid crystal, module substrates with semiconductor components packaged, and other printed wiring substrates. In addition, the substrate material is subjected to a surface treatment with a treatment liquid in order to form a circuit in a preceding process such as a development process, an etching process, and a peeling process. The substrate material is then cleaned in a cleaning device for post-processing with a cleaning solution to remove the adhered and remaining processing solution. In addition, the cleaning device can be used not only for the post-processing of such a processing program, but also for the pre-processing of the processing program. In this case, in order to prepare the processing program, the cleaning solution will be attached to the Clean and remove the fine dust of the substrate material or others.

In addition, after the cleaning liquid sprayed from the upper-side cleaning nozzle is subjected to the cleaning treatment, most of the cleaning liquid flows on the substrate material to the left and right and falls from the left and right side ends.

(D) Implementation < About the drawings > The present invention will be described in detail below based on the embodiments of the invention shown in the drawings. Figures 1, 2 and 3 are diagrams illustrating the embodiments of the present invention. FIG. 1 is a side sectional explanatory view. Fig. 2 is a plan explanatory view. (1) of FIG. 3 is an explanatory diagram of a bottom surface of a hole-shaped nozzle, (2) is an explanatory diagram of a bottom surface of a slit-shaped nozzle, and (3) is a plan explanatory diagram of a printed wiring board (substrate material). < About substrate B > The cleaning device 1 is a process for producing a substrate B for use in a circuit A. Therefore, the description of the substrate B is as follows (see Fig. 3 (B)). -13- 565473 The substrates for Circuit A are widely used in various electronic devices. The types include single-sided substrates, double-sided substrates, and multi-layer substrates (including the most recent deposition method (bu i 1 d-up)). . In addition, as a part of such a substrate b, there is also a module substrate (semiconductor) that integrates semiconductor components such as 1C (Integrated Circuit), LSI (Large Integrated Circuit), passive components, drive components, and capacitors with Circuit A Package substrate), or a glass substrate embedded with semiconductor components in the glass substrate and circuit A, that is, a glass substrate for a plasma display PDP (plasma display panel), a glass substrate for a liquid crystal LCD, or a chip-type package (CSP ), Plastic ball grid array substrate PBGA, etc. Of course, the substrate B mentioned in the patent specification of this case includes such substrates in addition to the previous printed wiring substrate. According to such a substrate A for the circuit A, as the electronic device is becoming more high-performance, more functional, smaller, and lighter, it is continuously advancing to high precision, compactness, ultra-thinning, and multilayering. On the outer surface, that is, the single-sided or double-sided circuit A on the upper surface, the lower surface, or the lower surface, and even the circuit A formed in the interior, the density and miniaturization are very significant. The substrate B is, for example, a printed wiring board, and its width and height are composed of, for example, 500 mm × 500 mm. The thickness of the substrate B is 1.0 mm to 60 μm. The thickness of the circuit A is 75 μm to 35 μm. Thinned to about 25 microns to 10 microns. In the case of a multilayer substrate, the overall thickness is also extremely thin to about 1.0 mm to 0.4 mm. The line width of the circuit A or the line width of the circuit A is about 35 μm to 25 μm, and there is also a tendency for miniaturization. The substrate B has a structure as described above. -14- 565473 < Example of manufacturing method of substrate B > A method for manufacturing the substrate B using the cleaning apparatus 1 will be described below. First, the manufacturing method of the first example will be described. In the first example manufacturing method, the printed wiring board of the first example of the substrate B is manufactured through the following process. First, prepare the substrate material C of a copper-clad laminated board. The copper-clad laminated board is formed by pasting a copper foil on the outer surface of an insulating layer (core material) made of resin, glass cloth, or ceramics with a 'thermocompression machine'. By. Then, a perforation process for a through hole is performed by a method such as laser. · The through hole is a through hole between the two outer surfaces of the substrate material C (substrate B). 'Each piece is formed with hundreds or more of extremely small diameters whose diameter is about 0.5 mm to 0.2 mm or less. For more. The through hole is used for connecting between two external surfaces or circuit A of a multilayer substrate, or for assembling components mounted on circuit A. Recently, the NMBI [Neo-Manhattan Bump Interconnection] method has also been developed. The _ NMBI is a technology that uses small bump-shaped bumps instead of through-holes, and achieves the same function as through-holes through soldering pads without the need for through-hole processing. Then, on the outer surface (one or both of the upper surface, the lower surface, and the lower surface of the copper foil of the substrate material C), a photoresist is applied or pasted together in a film form. Next, a photo of the circuit depicting the negative of circuit A is placed. After exposure, the photoresist on the outer surface is left to be exposed and hardened to form part of circuit A. The other unnecessary parts are dissolved and removed by spraying a developing solution . -15-565473 Then the copper foil of the substrate material c will leave a part of the circuit A covered by the photoresist after hardening, and the unnecessary part of the photoresistive uranium resist that is dissolved and removed after development is sprayed. The etching solution (copper chloride (II), iron oxide (II)) is dissolved and removed to perform etching. Then, the remaining circuit A forming part is peeled off by spraying a peeling liquid, and the copper foil formed by the remaining circuit A is on the outer surface of the substrate material C (upper surface, upper surface, lower surface, and back surface). Or double-sided) to form a predetermined circuit A, so that a substrate B can be obtained, that is, a printed wiring substrate. In addition, for the above-mentioned development procedure, etching procedure, and peeling procedure, for the respective post-processing, or for the post-processing after the peeling procedure, a cleaning program for spraying a water washing liquid, a neutralizing agent liquid, and other cleaning nozzles is attached. (2) The processing liquids such as the developing solution, the etching solution, and the peeling liquid adhering to the outer surface of the substrate material C are cleaned and removed. The manufacturing method of the first example is constituted by such a wet method. The conventional manufacturing method is as described above. Next, the manufacturing method of the second example is explained as follows. The manufacturing method of the printed wiring board, which is an example of the substrate B, is based on the wet method of the first example described above, but the semi-additive method of the first example is also being used in most cases. In this semi-additive method, an electroless copper-plated film is first formed on the outer surface (one or both of the upper surface, the lower surface, and the lower surface) of a substrate material C in which a through hole is formed in advance. -Then, after the photoresist is coated or pasted on the non-electrolytic copper-plated film in the form of a film,-a photo of a circuit on which a negative film of circuit A is depicted is placed and exposed. -Therefore, the photoresist leaves 565473 part hardened by exposure, and the other part, namely, the circuit A forming part, is dissolved and removed by spraying the developing solution. Then—electrolytic copper plating is applied to the circuit A forming portion, that is, the electroplated film pattern portion where the photoresist is dissolved and removed by the development process, that is, the portion where the non-electrolytic copper plating film is exposed—to form the circuit A. In addition, the remaining photoresist other than the hardened circuit A forming part will be removed by spraying a stripping solution, and the exposed non-electrolytic copper plating film will be melted by rapid etching by spraying the etching solution. Remove. -> In addition, a washing procedure is also added as described above for post-processing of each procedure. The semi-additive method of the second example is to form a circuit A by electrolytic copper plating in such a manner to manufacture a substrate B, that is, a printed wiring substrate. The second example is configured as described above. However, the manufacturing method of the printed wiring board and the manufacturing method of the substrate B for other circuits A are becoming more and more diversified recently. In addition to the above-mentioned first and second examples, various methods have been developed and used. Of course, the present invention can also be applied to the manufacturing methods of such various printed wiring boards and other substrates B. The manufacturing method of the board | substrate B is comprised as mentioned above. < About the cleaning device 1 > The following describes the cleaning device 1 with reference to Figs. 1 to 3. The cleaning device 1 is a process for preparing the substrate B in the above-mentioned substrate B. The substrate material C is subjected to a surface treatment with a treatment liquid D in order to form a circuit A, and is washed with a cleaning liquid. -17-565473 For example, it is used for post-processing of the development process, etching process, and peeling process, that is, to remove and adhere to the substrate material C after the surface treatment for forming the circuit A that has been applied in the preceding steps. A processing solution D such as a developing solution, an etching solution, and a peeling solution. In the first figure, 2 is a processing chamber 2 of the preceding procedure, 3 is a nozzle for spraying the processing liquid D on the substrate material C, and 4 is a liquid tank of the processing liquid D. The substrate material C is surface-treated by the conveyor 6 using the rollers 5 while being conveyed in a horizontal posture, as shown in the figure, while the treatment liquid D is sprayed from the nozzles 3 arranged opposite each other. In addition, as shown in the figure, the cleaning device 1 has three cleaning chambers 7 and an air chamber 8 arranged in order from the upstream side to the downstream side in the conveying direction. Each cleaning chamber 7 is provided with a cleaning nozzle 9. In the cleaning chamber 7 at the rear end, a reverse nozzle 10 is arranged immediately after the cleaning nozzle 9 at the last stage. The air chamber 8 is provided with an air nozzle 11. The cleaning nozzle 9 or the reverse nozzle 10 and the air nozzle 11 are arranged in separate rooms in this manner. In this way, the cleaning device 1 is sequentially provided with a cleaning nozzle 9 for spraying the cleaning liquid E from the substrate material c conveyed by the conveyor 6 from the upstream side to the downstream side in the conveying direction F to the upstream. A reverse nozzle 10 for spraying fluid such as the cleaning liquid E on the side, and an air nozzle 11 for spraying air G. The cleaning device 1 has a structure as described above. < About Conveyor 6 >-1 8-565473 The description of the first conveyor in conjunction with the conveyor 6 is as follows. The conveyor 6 has five rollers or wheels as shown in the figure, and can convey the substrate material C in a horizontal posture. In other words, as shown in the figure, the conveyors 6 of the cleaning device 1 are formed by arranging a plurality of rollers 5 that are rotationally driven in the forward and backward conveying direction F. The conveyor 6 passes through the cleaning chamber 1 and the air chamber 8 of the washing device 1 from the processing chamber 2 of the preceding process, and is continuously arranged toward the drying chamber 12 constituted by a furnace or the like of the subsequent process. The substrate material C is placed on the rollers 5 of the conveyor 6 as described above, and can be moved from the upstream side to the downstream side in a horizontal posture along the conveyance direction F. The conveyor 6 is configured as described above. < About cleaning nozzle 9 > Next, the cleaning nozzle 9 will be described with reference to Figs. 1 and 2. The cleaning nozzle 9 of the cleaning device 1 is disposed at least on the upper side of the substrate material C being conveyed, and is connected to a pump or a liquid tank 14 through a pipe 13. In addition, a plurality of cleaning nozzles 9 are arranged opposite to each other in front, back, left, and right of the substrate material C to be conveyed, and are used to spray water washing liquid or other cleaning liquids. The cleaning nozzle 9 will be described in more detail as follows. In each of the cleaning chambers 7, nozzles 15 are arranged on the upper and lower sides of the substrate material C for a double-sided substrate as shown in the figure at a specific vertical interval with respect to the substrate material C. In each of the cleaning chambers 7, the nozzles 15 are arranged along the left-right width direction of the substrate material C to be conveyed so as to cover the full width of the substrate material C, and a plurality of branches are arranged in the front-rear conveyance direction F with the front-rear interval. It is configured into plural segments. -19- 565473 In addition, for each of the nozzles 15 above, the cleaning nozzles 9 are provided directly above or below the opposite surface (upper or lower) of the substrate material C at a specific interval in the width direction. . In addition, the cleaning nozzle 9 uses a plurality of blowout holes arranged in the width direction of the nozzle 15 as shown in the example shown in FIG. 2 or 3 (1), or does not follow this. As an example of the drawing, as shown in FIG. 3 (2), the nozzle 15 is arranged in a linear single slit shape in the width direction. The cleaning solution E is pressure-fed to the nozzle 15 through each of the cleaning chambers 7 through the pipes 13 and is sprayed from the cleaning nozzle 9 of each nozzle 15 to the substrate material C conveyed in a horizontal posture. The sprayed cleaning solution E flows on the outer surface (upper surface, lower surface, or lower surface) of the substrate material C in the right or left width direction, and then flows down from the left and right sides. , —And flow into the lower liquid tank 14 for recycling. —The washing liquid E recovered in the liquid tank 14 is stored, and at the same time—it is pumped to the piping 13 afterwards—and recycled. The cleaning solution E is mainly a water-based cleaning solution, but a cleaning solution E mixed with a neutralizing agent or other chemical solution is often used. The cleaning nozzle 9 is configured as described above. < About the reverse nozzle 10 > The description of the first nozzle and the second nozzle with respect to the reverse nozzle 10 will be described below. The reverse nozzle 10 of the cleaning device 1 is disposed on the upper side with respect to the substrate material C to be conveyed, and is disposed obliquely downward and inclined toward the upstream side opposite to the conveying direction, and is disposed oppositely through a pipe 16 Connected to the liquid tank 14 to spray water washing liquid E or other washing liquid -20-565473. The reverse nozzle 10 is arranged to cover the entire width of the nozzle, and is composed of a slit-shaped nozzle that is linear in the width direction from left to right. Ε sprayed into a curtain. Alternatively, a so-called flat nozzle may be used instead of the slit-shaped nozzle. Therefore, by spraying the cleaning liquid E, the cleaning liquid E sprayed by the cleaning nozzle and held on the substrate material can be pushed back to the upstream side, so that the cleaning liquid E can be removed from the substrate material. The left and right sides shed. A more detailed description of such a reverse nozzle 10 is as follows. After the cleaning nozzle 9 at the last stage of the cleaning chamber 7 at the rear end, an aqua pipe 17 is arranged at intervals between the front and rear, as shown in the figure. The liquid pipe 17 is arranged on the upper side of the substrate material C with a specific vertical interval therebetween, and is provided in a right-left width direction so as to cover the entire width range of the substrate material C. In addition, as shown in FIG. 2 and FIG. 3 (2), such a liquid pipe 17 is provided with a slit-shaped nozzle in a straight line as the reverse nozzle 10. As shown in FIG. This reverse nozzle 10 is disposed on the substrate C relatively to the upstream side, for example, inclined downward from the horizontal plane, for example, 45 degrees, or the like. Therefore, after the cleaning liquid E is pressure-fed to the liquid tube 17 through the piping 16, the substrate material C conveyed from the reverse nozzle 10 of the liquid tube 17 obliquely upward to the substrate material C in a horizontal posture is sprayed into a flat curtain shape. . —And the sprayed cleaning solution E can push the cleaning solution E remaining on the substrate material C back to the upstream side, and together with the pushed-back cleaning solution £ 565473 on the substrate to the left and right width direction The puppet flows, flows down from the left and right ends, and is recovered in the 'liquid tank 14' in the lower part. -The cleaning liquid E recovered in the liquid tank 14 is stored together with the cleaning liquid E sprayed, flowed down, and recovered from the cleaning nozzle 9 described above, but is still pumped to the pipe 16 by pumping,- And recycle. Regarding the cleaning solution E, please refer to the paragraphs stated for the cleaning nozzle 9 previously. In addition, the reverse nozzle 10 uses a slit type as shown in the figure. However, instead of using this type, it can also be used. As shown in (1) of Figure 3, the liquid pipes 17 are arranged in the width direction. There are many types of blowout holes. Of course, such a blow-out hole type can also be arrange | positioned diagonally down to the upstream side similarly to a slit-shaped type. In addition, from the reverse nozzle 10, as shown in the figure, the water washing liquid or other washing liquid E for recycling is sprayed. However, instead of this method, the water washing liquid supplied through the water system can also be used as the washing liquid E. For use, after use, it will be drained and used as a waste liquid disposal method. Alternatively, it may be configured to spray air. Regarding the method of spraying air, refer to the following paragraphs about the air nozzle 11. The reverse nozzle 10 is configured as described above. < About the air nozzle 11 > The description of the air nozzle 11 1 with reference to Figs. 1 and 2 is as follows. The air nozzle 11 of the cleaning device 1 is disposed at least on the upper side of the substrate material to be conveyed, and is connected to an air source such as an air compressor via a pipe 18 to spray air G and blow. -22-565473 The air nozzle 11 is arranged to cover the full width of the substrate material being conveyed. It consists of slit-shaped nozzles that are linear in the left and right width directions, and are arranged opposite to each other while inclined toward the upstream side. The substrate G is used to incline the air G toward the upstream side and spray it into a curtain shape. And by spraying such air G, most of the cleaning liquid remaining after the majority of the cleaning liquid is removed through the reverse nozzle or by natural fall is removed by the substrate material C. Hereby, the air nozzle 11 is explained in more detail as follows. The cleaning device 1 is originally provided with an air chamber 8 in the cleaning room 7 immediately after the rear end, and an air duct 19 is provided as shown in the figure. The air duct 19 is arranged on the upper and lower sides of the substrate material C for the double-sided substrate at a specific vertical interval with respect to the substrate material C, as shown in the figure, and covers the entire width of the substrate material C. The mode is set along the left and right width directions. The other example is configured with upper and lower branches, but of course it can also be configured with multiple branches each. In addition, as shown in Fig. 2 and Fig. 3 (2), the two air ducts 19 are provided with a slit-shaped spray 1 that is linear in the width direction as air nozzles 11. The upper air nozzle 11 is arranged on the upstream side of the substrate material C, and is inclined downwardly at an angle of, for example, 45 degrees from the horizontal plane. The air nozzles 11 on the lower side are arranged on the upstream side, for example, at an angle of 45 degrees upward from the horizontal plane, so as to rise and incline, and are relatively disposed below the substrate material C. Air G is supplied by air compressors, blowers, air pumps, fans, and other air sources (not shown),-> after being sent to the air pipe 19 through the pipe 18 '-23- 565473 — air from the air pipe 19 The nozzle 11 conveys the substrate material C which is conveyed in a horizontal posture from the upper part to the lower part and the upper part to the lower part, as shown in the figure. -Therefore, the air G sprayed in this manner can remove the cleaning liquid E remaining on or under the substrate material C. According to the air G sprayed in this way, if the thickness of the cleaning liquid E retained in the substrate material C is about several millimeters, its removal effect is limited, but when only a small amount is retained, it can be efficiently removed. In particular, the air G can be effectively removed when heated air is used. The air nozzle 11 is a slit-shaped type as shown in the figure, but the air nozzle 19 is not used in accordance with the figure as shown in (1) of FIG. 3, and has a plurality of blowout holes arranged in the width direction. Of course, the blowout hole pattern should be arranged so that it is inclined to the upstream side in the same way as the slot type. The air nozzle 11 is configured as described above. < About Action > The present invention is configured as described above. Therefore, it has the following effects. The cleaning device 1 can be used in the manufacturing process of the substrate B. That is, processes for manufacturing glass substrates for plasma displays, glass substrates for liquid crystals, module substrates packaged with semiconductor components, and other printed wiring substrates. In addition, the substrate material C is first surface-treated with an acidic or alkaline treatment liquid in order to form a circuit in the previous procedure. For example, in a development process, an etching process, a peeling process, etc., the substrate material C is sprayed with a treatment liquid D and then subjected to a surface treatment (see FIG. 1). -2 4-565473 Then the substrate material c will be sent to the cleaning device 1, and the cleaning process will be performed for post-processing, so that the cleaning solution E for the treatment liquid D attached and remaining after the surface treatment in the previous procedure is used. Wash and remove. In other words, “The substrate material C is conveyed in the cleaning device 1 by the conveyor 6 having the roller group 5 or the wheel group in a horizontal posture while being conveyed in the conveying direction F from the upstream side to the downstream side. Wash nozzle 9, reverse nozzle 10, air nozzle 1 1 (see figure 丨). First, the cleaning nozzle 9 sprays the cleaning liquid E on the substrate material C (see FIG. 1 and FIG. 2). Φ That is, the cleaning nozzle 9 is arranged at least on the substrate material c-side (upper side and lower side in the example shown), and is connected to the liquid tank 14 through a nozzle 15 or a pump. In addition, a plurality of cleaning nozzles 9 are disposed in front of and behind the substrate material c, and are provided with a plurality of cleaning nozzles for spraying water or other cleaning liquid on the substrate material, thereby cleaning and removing the attached and remaining processing liquid D. In addition, the cleaning liquid e sprayed from the upper cleaning nozzle 9 cleans the base material and material C, and most of it flows to the left and right on the substrate material c (the width direction H orthogonal to the conveying direction) ), The left and right side ends flow down, fall down, and are recovered. On the other hand, the cleaning liquid E 'sprayed from the lower cleaning nozzle 9 cleans the bottom surface of the substrate material c, and almost all of them are naturally recovered from the bottom surface of the substrate material C by gravity. Next, the reverse nozzle 10 will spray a fluid such as the cleaning liquid E on the substrate material C (see Figs. 1 and 2). '25 -565473 That is, the reverse nozzle 10 is a slit-shaped nozzle which is arranged on the substrate material C to be conveyed and covers the entire width of the substrate material C in a straight line in the left-right width direction. Further, it is disposed inclined toward the upstream side opposite to the conveying direction F, and is connected to the pump or the liquid tank 14 via a liquid pipe 17 or a pipe 16. Therefore, the reverse nozzle 10 can incline the water washing liquid or other cleaning liquid E toward the upstream side and spray it into a curtain shape on the substrate material c being conveyed. By spraying the cleaning liquid E and the like from the reverse nozzle 10, the cleaning liquid e sprayed from the cleaning nozzle 9 and stayed on the upper side can be pushed back to the upstream side. That is, the cleaning liquid E sprayed onto the substrate material C via the cleaning nozzle 9 is mostly recovered from the left and right side ends of the substrate material C as described above, but is still recovered. The thickness is left and right on the substrate material C. However, such a thickly retained cleaning liquid E can be pushed back to the upstream side by injecting the cleaning liquid E and the like into a curtain shape by inverting the upstream side through the reverse nozzle 10 to incline downwards. . The sprayed cleaning liquid E, etc., is stronger than the air sprayed into the curtain, and has a strong impulse for thick detainees, and most of it can be pushed back to the upstream side. The pushed-back cleaning solution E will flow down, fall, and be recovered from the left and right side ends of the substrate material C as described above. According to the nearest substrate B, such as a glass substrate, the workpiece size is large

Finally, the air nozzle 11 is to spray the air G on the substrate material C output from the cleaning chamber 7 (see FIG. 1 and FIG. 2). The air nozzles 11 are arranged in separate air chambers 8 from the cleaning chamber 7 in which the cleaning nozzles 9 or the reverse nozzles 10 are arranged, and are arranged on at least the upper side of the substrate material C being conveyed (the example in the figure is the upper side and the lower side). Side), and is composed of a slit-shaped nozzle that is arranged so as to cover the entire width of the substrate material C and is linear in the width direction. And it is inclined and arranged opposite to the upstream side, and is connected to an air compressor or other air source through a duct 9 or a pipe 18, and is used to incline the air G toward the upstream side of the substrate material C that is conveyed and spray it into The curtain is blown. By spraying the air G from the air nozzle 11 as described above, a small amount of the cleaning liquid E remaining after being largely removed by the reverse nozzle 10 or by natural fall can be removed from the substrate material C. In other words, as described above, the upper surface of the substrate material C is sprayed by the cleaning liquid E from the reverse nozzle 10, and the lower surface of the substrate material c is only a little cleaning liquid E because it naturally falls. It will remain as a very thin curtain. It can be said that it is extremely effective to use the air G blown by the air nozzles 11 in a curtain shape to remove such a very small amount of liquid. In other words, the tongue says, 'The curtain of air G is not suitable for the removal of a large amount of cleaning solution, but it is suitable for the complete removal of a small amount of cleaning solution E. 565473 For example, if a large amount of the remaining cleaning liquid E is sprayed and blown with air G, the cleaning liquid E will be scattered from the substrate material C and float, and then adhere to the substrate material C again. On the other hand, even if a very small amount of retained cleaning liquid E is sprayed with air G, such scattering and re-attachment will not occur. Therefore, the cleaning liquid E can be reliably removed by air G. In this way, according to the cleaning device 1, the cleaning liquid E used for the cleaning process can be reliably removed from above or below the substrate material C. In addition, the cleaning liquid E sprayed below the substrate material C through the cleaning nozzle 9 disposed on the lower side is almost completely dropped by the substrate material C after being subjected to the cleaning treatment, and is recovered by gravity, so Since a large amount of the above-mentioned cleaning solution E is retained on the substrate material C, the reverse nozzle 10 need not be disposed. In other words, only a small amount of the cleaning liquid E remains on the bottom surface of the substrate material C, so that only the air G is sprayed from the air nozzle 11 disposed on the bottom surface, and the G liquid can be reliably removed. The cleaning device 1 is provided with a reverse nozzle 10 between the cleaning nozzle 9 and the air nozzle 11 and constitutes a reverse nozzle 10 with a slit-shaped nozzle, and is connected to a pump or a liquid through a pipe 16 Simple structure made of grooves. In addition, the cleaning device 1 can be easily added to an existing conventional cleaning device in an additional manner. [Comparison with the effect of the prior art] < Characteristics of the present invention >-2 8-565473 The cleaning device 1 of the present invention is characterized in that a reverse nozzle is disposed between the cleaning nozzle and the air nozzle as described above, and is directed upstream. It is constituted by spraying a cleaning liquid, etc., and pushing back the cleaning liquid retained on the substrate material. Therefore, the cleaning device of the present invention can exert the following effects. < First effect > First, the cleaning liquid can be effectively removed from the substrate. That is, according to the cleaning device of the present invention, since the cleaning liquid sprayed by the reverse nozzle can be pushed back to the upstream side, the cleaning liquid sprayed by the cleaning nozzle and retained on the substrate material can be almost completely removed The left and right sides of the substrate material flow down and fall. In this way, only a small amount of cleaning liquid remains on the substrate material, so that the air blown by the air nozzle can be effectively and completely removed. Therefore, it is possible to surely eliminate the occurrence of water droplets remaining on the substrate material that has passed through the air nozzle, or the occurrence of spots and stains, as in the conventional cleaning device described above. Therefore, it is possible to surely prevent the occurrence of obstacles in the subsequent procedures, or cause oxidation or erosion of the circuit, or cause obstacles in the semiconductor assembly, thereby avoiding the danger of various circuit failures. In this way, for such substrates where the density and miniaturization of circuits are continuously progressing, it is expected to improve the quality or reduce the occurrence of defective rates. < Second effect > Second, it is superior in terms of cost and can be realized. That is, the cleaning device of the present invention has a simple structure in which a reverse nozzle is provided between the cleaning nozzle and the air nozzle, so that the above-mentioned first point can be easily realized. 565473 In other words, compared with the above-mentioned conventional cleaning device, the number of required air nozzles can be greatly reduced, and the equipment cost can be greatly reduced. This is because the conventional device requires a plurality of high-precision and very expensive air nozzles to be provided in multiple stages. In addition, since a large amount of air is no longer required to be equipped with an air source such as a large-capacity air compressor, it is also advantageous in terms of power costs, maintenance costs, and running costs. As described above, all the problems existing in such a conventional method can be solved, and the effect exerted by the present invention is extremely remarkable.
