以下將參照相關圖式,說明依本發明較佳實施例之一 種三維形狀微奈米結構及其製造方法,其中相同的元件將 以相同的參照符號加以說明。 請參照圖1所示,本發明較佳實施例之一種三維形狀 微奈米結構之製造方法係包含步驟S01至步驟S03。以下 以不同實施例來說明三維形狀微奈米結構之製造方法。 請參照圖2A至圖2E,其係繪示依照本發明之第一實 施例之一種三維形狀微奈米結構之製造方法的示意圖。如 圖2A所示,本實施例之製造方法係應用於一基板10,基 板10設有至少一第一蝕刻材料層11及一第二蝕刻材料層 12,第二蝕刻材料層12位於基板10與第一蝕刻材料層11 之間。於此,第二蝕刻材料層12係貼合於基板10上,且 第一蝕刻材料層11係貼合於第二蝕刻材料層12上,然而 這僅為舉例,並非用以限制本發明,在其他實施例中,第 二蝕刻材料層12與基板10之間可有其他材料層,第一蝕 刻材料層11與第二蝕刻材料層12之間可有其他材料層。 於此不限制基板10、第一触刻材料層11及第二I虫刻 材料層12之材質。基板10可例如包含矽、高分子聚合物 糸列材料、有機材料、塑膠材料、半導體材料、金屬材料、 石英、玻璃材料、陶瓷材料、無機材料、上述材料中任二 者或任二者以上所組成之材料。第一蝕刻材料層11及第 二蝕刻材料層12可例如包含金屬材料、半導體材料、陶 兗材料、有機材料、塑膠材料、兩分子材料、導電材料、 201209905 磁性材料、無機材料、或上述材料中任二者或任二者以上 所組成之材料。 如圖2B所示,首先進行一轉印步驟(S01),其係藉 由一模仁20將一轉印材料層21轉印至基板10之第一蝕 刻材料層11。於此,模仁20之一側具有複數凹部22及複 數凸部23,轉印材料層21設置於具有凹部22及凸部23 之該側上,並可為一連續之膜層、或僅局部設置於凸部23 上、或局部設置於凸部23及凹部22上。轉印材料層21 φ 可例如藉由熱蒸鑛、電子束蒸鑛法、化學氣相沉積或物理 氣相沉積等方式形成於模仁20上。轉印材料層21之材質 可為金屬、氧化物或介電材料,例如可為鉻(Cr)金屬或 介電材料二氧化碎(Si〇2)。 模仁20的材料本身可具有抗沾黏特性,以使轉印材 料層21順利脫離模仁20之凸部23,例如模仁20包含乙 稀-四氟乙烯共聚物(ethylene tetrafluoroethylene,其化學 式:-(C2H4-C2F4)-)。或者,如本實施例之圖2B所示, I 模仁20更設有一抗沾黏層24,其可例如藉由熱蒸鍵 (Evaporation)技術言臾置於模仁20之凹部22及凸部23 上,然後轉印材料層21再設置於抗沾黏層24上,同樣地, 抗沾黏層24可使轉印材料層21順利脫離模仁20之凸部 23並轉印至第一蝕刻材料層11上。抗沾黏層24例如包含 有機材料、無機材料、高分子材料、陶瓷材料、金屬材料、 鐵弗龍材料、類鑽碳材料、碳氟化合物(CxFy)經電漿解 離後之沉積材料、或上述材料中任二者或任二者以上所組 201209905 成之材料。 在轉印過程中,係藉由壓印而將模仁20具有轉印材 料層21之該側與基板10之第一姓刻材料層11相對壓合, 並使模仁20之凸部23上之轉印材料層21的部分壓合在 基板10之第一蝕刻材料層11上並與其互相接觸,而將轉 印材料層21轉印至第一蝕刻材料層11上。其中,若第一 触刻材料層11為液狀,可在轉印後對第一#刻材料層11 進行烘烤,例如以95°c烘烤5分鐘,以將第一蝕刻材料層 11烤乾,待溫度降至室溫後,再將模仁20自第一蝕刻材 料層11上移除,此時由於模仁20之凸部23上覆設有抗 沾黏層24,而使抗沾黏層24介於模仁20與轉印材料層 21之間、或者所採用之模仁20本身具有抗沾黏特徵,因 此模仁20之凸部23上的轉印材料層21之部分可順利脫 離模仁20而轉印至第一银刻材料層11上,而完成轉印步 驟。 如圖2C所示,轉印步驟完成後,轉印材料層21的一 部分轉移至第一蝕刻材料層11之一部分上,並露出第一 蝕刻材料層11之另一部分,使得轉印材料層21可作為接 下來第一蝕刻步驟(S02)之遮罩(mask)。 接著,如圖2C及圖2D所示,進行一第一蝕刻步驟 (S02),其係以基板10上之轉印材料層21作為遮罩,對 第一蝕刻材料層11及第二蝕刻材料層12進行蝕刻。如圖 2D所示,在第一蝕刻步驟之後,未受轉印材料層21覆蓋 之第一蝕刻材料層11及第二蝕刻材料層12之部分係被移 201209905 除;當然,在其他實施例中,未受轉印材料層21覆蓋之 第一蝕刻材料層11及第二蝕刻材料層12之部分,可藉由 第一蝕刻步驟而形成不同的形狀,即第一蝕刻材料層11 及第二姓刻材料層12不完全I虫刻完。 第一蝕刻步驟可例如包含乾式蝕刻或溼式蝕刻方 式,並以位在第一蝕刻材料層11上的轉印材料層21作為 I虫刻遮罩,來移除未由轉印材料層21所覆蓋之第一 i虫刻 材料層11及第二蝕刻材料層12之部分。上述所採用之乾 • 式蝕刻技術可例如為反應性離子蝕刻(RIE)或感應耦合 電漿(ICP)離子蝕刻技術。在一些實施例中,利用反應 性離子蝕刻或感應耦合電漿離子蝕刻等乾式蝕刻方式進 行第一蝕刻材料層11及第二蝕刻材料層(例如聚亞醯胺) 12之蝕刻時,可利用氧氣作為主要的反應氣體,例如採用 氧氣或特定比例之氧氣與氬氣作為蝕刻之反應氣體。 根據實驗發現,以傳統微影技術來圖案化聚亞醯胺 層,是使用光感式光阻材料來作為蝕刻遮罩,由於光阻層 ^ 在顯影過程中會因吸收了部分的顯影液而產生腫脹現 象,因此光阻層的體積會膨脹,因而以此體積膨脹之光阻 層作為蝕刻罩幕來進行下方材料層的圖案蝕刻時,會導致 所形成之材料層圖案結構的尺寸失真。然而,在本發明之 較佳實施例中,由於係以位在第一蝕刻材料層11上的轉 印材料層21來作為蝕刻遮罩,而非以光阻層來作為蝕刻 遮罩,轉印材料層21未經曝光與顯影過程,而不會因顯 影液的影響而導致體積膨脹,因此以轉印材料層21作為 11 201209905 蝕刻罩幕,可確保颠刻後之第一敍刻材料層u 刻材料層12層的圖案結構失 /、第一蝕 精度。 #爛材枓層12之圖案結構的 然後,如® 2D及圖2E所示,進行 =03),其係對第—_材料層n及第二❹料们

The anti-adhesion layer 24 includes, for example, an organic material, an inorganic material, a polymer material, a ceramic material, a metal material, a Teflon material, a diamond-like carbon material, a deposition material of a fluorocarbon (CxFy) after plasma dissociation, or the above Materials of any of the two or more materials of the group 201209905. In the transfer process, the side of the mold core 20 having the transfer material layer 21 is pressed against the first surname material layer 11 of the substrate 10 by embossing, and the convex portion 23 of the mold core 20 is placed thereon. A portion of the transfer material layer 21 is pressed against the first etching material layer 11 of the substrate 10 and brought into contact with each other, and the transfer material layer 21 is transferred onto the first etching material layer 11. Wherein, if the first etchant layer 11 is in a liquid state, the first etched material layer 11 may be baked after transfer, for example, baking at 95 ° C for 5 minutes to bake the first etched material layer 11 After the temperature is lowered to room temperature, the mold core 20 is removed from the first etching material layer 11, and at this time, since the convex portion 23 of the mold core 20 is covered with the anti-adhesion layer 24, the anti-sticking layer is applied. The adhesive layer 24 is interposed between the mold core 20 and the transfer material layer 21, or the mold core 20 itself has an anti-sticking property, so that the portion of the transfer material layer 21 on the convex portion 23 of the mold core 20 can be smoothly performed. The transfer to the first silver engraving material layer 11 is carried out from the mold core 20, and the transfer step is completed. As shown in FIG. 2C, after the transfer step is completed, a portion of the transfer material layer 21 is transferred to a portion of the first etch material layer 11 and another portion of the first etch material layer 11 is exposed, so that the transfer material layer 21 can be As a mask of the next first etching step (S02). Next, as shown in FIG. 2C and FIG. 2D, a first etching step (S02) is performed in which the transfer material layer 21 on the substrate 10 is used as a mask, and the first etching material layer 11 and the second etching material layer are applied. 12 is etched. As shown in FIG. 2D, after the first etching step, portions of the first etch material layer 11 and the second etch material layer 12 that are not covered by the transfer material layer 21 are removed by 201209905; of course, in other embodiments The portions of the first etch material layer 11 and the second etch material layer 12 that are not covered by the transfer material layer 21 may be formed into different shapes by the first etching step, that is, the first etch material layer 11 and the second surname The layer of engraved material 12 is not completely finished. The first etching step may include, for example, a dry etching or a wet etching method, and the transfer material layer 21 positioned on the first etching material layer 11 is used as an I-cut mask to remove the layer 12 not removed by the transfer material. A portion of the first i-etching material layer 11 and the second etching material layer 12 are covered. The dry etching technique employed above may be, for example, reactive ion etching (RIE) or inductively coupled plasma (ICP) ion etching. In some embodiments, when etching the first etch material layer 11 and the second etch material layer (eg, polyimide) by dry etching such as reactive ion etching or inductively coupled plasma ion etching, oxygen can be utilized. As the main reaction gas, for example, oxygen or a specific ratio of oxygen and argon are used as the etching reaction gas. According to experiments, it is found that the conventional lithography technology is used to pattern the polyimide layer by using a light-sensitive photoresist as an etch mask, because the photoresist layer absorbs part of the developer during development. The swelling phenomenon occurs, so that the volume of the photoresist layer is expanded. Therefore, when the volume-expanded photoresist layer is used as an etching mask to perform pattern etching of the underlying material layer, the size of the formed material layer pattern structure is distorted. However, in the preferred embodiment of the present invention, since the transfer material layer 21 positioned on the first etch material layer 11 is used as an etch mask instead of the photoresist layer as an etch mask, transfer The material layer 21 is not exposed and developed, and does not cause volume expansion due to the influence of the developer. Therefore, the transfer material layer 21 is used as an 11 201209905 etching mask to ensure the first layer of material after the engraving. The pattern structure of the 12 layers of the engraved material layer is lost/first etching precision. ################################################################################ Material layer u: material layer 12 has a second rotation, the first - second ratio = ratio of the ratio is less than 3 (), and the first layer of material: two leaves the fourth (four) material layer 12 .
