Description
本發明有關於一種具快拆功能的粉末原子層沉積設備,可快速將真空腔體由軸封裝置上卸下,或者是將真空腔體固定在軸封裝置上。 The present invention relates to a powder atomic layer deposition equipment with quick-release function, which can quickly remove the vacuum chamber from the shaft sealing device, or fix the vacuum chamber on the shaft sealing device.
奈米顆粒(nanoparticle)一般被定義為在至少一個維度上小於100奈米的顆粒,奈米顆粒與宏觀物質在物理及化學上的特性截然不同。一般而言,宏觀物質的物理特性與本身的尺寸無關,但奈米顆粒則非如此,奈米顆粒在生物醫學、光學和電子等領域都具有潛在的應用。 Nanoparticles are generally defined as particles smaller than 100 nanometers in at least one dimension that are physically and chemically distinct from macroscopic substances. In general, the physical properties of macroscopic substances are independent of their size, but this is not the case for nanoparticles, which have potential applications in fields such as biomedicine, optics, and electronics.
量子點(Quantum Dot)是半導體材料的奈米顆粒,目前研究的半導體材料為II-VI材料,如ZnS、CdS、CdSe等,其中又以CdSe最受到矚目。量子點的尺寸通常在2至50奈米之間,量子點被紫外線照射後,量子點中的電子會吸收能量,並從價帶躍遷到傳導帶。被激發的電子從傳導帶回到價帶時,會通過發光釋放出能量。 Quantum Dot (Quantum Dot) is a nanoparticle of semiconductor material. The currently studied semiconductor materials are II-VI materials, such as ZnS, CdS, CdSe, etc. Among them, CdSe has attracted the most attention. The size of quantum dots is usually between 2 and 50 nanometers. When the quantum dots are irradiated with ultraviolet light, the electrons in the quantum dots absorb energy and transition from the valence band to the conduction band. Excited electrons release energy by emitting light as they travel from the conduction band back to the valence band.
量子點的能隙與尺寸大小相關,量子點的尺寸越大能隙越小,經照射後會發出波長較長的光,量子點的尺寸越小則能隙越大,經照射後會發出波長較短的光。例如5到6奈米的量子點會發出橘光或紅光,而2到3奈米的量子點則會發出藍光或綠光,當然光色還需取決於量子點的材料組成。 The energy gap of quantum dots is related to the size. The larger the size of the quantum dot, the smaller the energy gap, and it will emit light with a longer wavelength after irradiation. The smaller the size of the quantum dot, the larger the energy gap, and the wavelength will be emitted after irradiation. shorter light. For example, quantum dots of 5 to 6 nanometers will emit orange or red light, while quantum dots of 2 to 3 nanometers will emit blue or green light. Of course, the light color depends on the material composition of the quantum dots.
應用量子點的發光二極體(LED)產生的光接近連續光譜,同時具有高演色性,並有利於提高發光二極體的發光品質。此外亦可透過改變量子點的尺寸調整發射光的波長,使得量子點成為新一代發光裝置及顯示器的發展重點。 Light emitting diodes (LEDs) using quantum dots produce light close to a continuous spectrum, and at the same time have high color rendering properties, which are beneficial to improve the luminous quality of light emitting diodes. In addition, the wavelength of the emitted light can be adjusted by changing the size of the quantum dots, making the quantum dots become the focus of the development of the new generation of light-emitting devices and displays.
量子點雖然具有上述的優點及特性,但在應用或製造的過程中容易產生團聚現象。此外量子點具有較高的表面活性,並容易與空氣及水氣發生反應,進而縮短量子點的壽命。 Although quantum dots have the above-mentioned advantages and characteristics, they are prone to agglomeration in the process of application or manufacture. In addition, quantum dots have high surface activity and easily react with air and water vapor, thereby shortening the life of quantum dots.
具體來說,將量子點製作成為發光二極體的密封膠時,可能會產生團聚效應,而降低量子點的光學性能。此外,量子點在製作成發光二極體的密封膠後,外界的氧或水氣仍可能會穿過密封膠而接觸量子點的表面,導致量子點氧化,並影響量子點及發光二極體的效能或使用壽命。量子點表面的缺陷及懸空鍵(dangling bonds)亦可能造成非輻射復合(non-radiative recombination),同樣會影響量子點的發光效率。 Specifically, when quantum dots are used as sealants for light-emitting diodes, agglomeration effects may occur, reducing the optical properties of quantum dots. In addition, after the quantum dots are made into the sealant of the light-emitting diodes, the external oxygen or moisture may still pass through the sealant and contact the surface of the quantum dots, resulting in oxidation of the quantum dots and affecting the quantum dots and light-emitting diodes. performance or service life. Defects and dangling bonds on the surface of quantum dots may also cause non-radiative recombination, which also affects the luminous efficiency of quantum dots.
目前業界主要透過原子層沉積(atomic layer deposition,ALD)在量子點的表面形成一層奈米厚度的薄膜,或者是在量子點的表面形成多層薄膜,以形成量子井結構。 At present, the industry mainly uses atomic layer deposition (ALD) to form a nanometer-thick film on the surface of the quantum dot, or to form a multi-layer film on the surface of the quantum dot to form a quantum well structure.
原子層沉積可以在基板上形成厚度均勻的薄膜,並可有效控制薄膜的厚度,理論上亦適用於三維的量子點。量子點靜置在承載盤時,相鄰的量子點之間會存在接觸點,使得原子層沉積的前驅物氣體無法接觸這些接觸點,並導致無法在所有的奈米顆粒的表面皆形成厚度均勻的薄膜。 Atomic layer deposition can form a thin film with uniform thickness on the substrate, and can effectively control the thickness of the thin film. It is also suitable for three-dimensional quantum dots in theory. When the quantum dots are placed on the carrier plate, there will be contact points between adjacent quantum dots, so that the precursor gas of atomic layer deposition cannot contact these contact points, and it is impossible to form uniform thickness on the surface of all nanoparticles. film.

The connecting
本發明的真空腔體11及軸封裝置13為兩個獨立的構件,其中真空腔體11可由軸封裝置13上卸下,或者是將真空腔體11固定在軸封裝置13上。當真空腔體11連接軸封裝置13時,會在兩者之間形成一密閉空間16,例如密閉空間16可為環狀體,並環繞在軸封裝置13的周圍。第一抽氣管線171流體連接密閉空間16,並用以抽出密閉空間16內的氣體,或者是將氣體輸送至密閉空間16。
The
第二抽氣管線179流體連接真空腔體11的反應空間12,並用以抽出反應空間12內的氣體,使得反應空間12為真空狀態,以進行原子層沉積製程。具體而言第二抽氣管線179可連接一幫浦,並透過幫浦抽出反應空間12內的氣體。
The
進氣管線173流體連接真空腔體11的反應空間12,並用以將一前驅物氣體或一非反應氣體輸送至反應空間12,其中非反應氣體可以是氮氣或氬氣等惰性氣體。例如進氣管線173可透過閥件組連接一前驅物氣體儲存槽及一非反應氣體儲存槽,並透過閥件組將前驅物氣體輸送至反應空間12內,使得前驅物氣體沉積粉末121表面。在實際應用時,進氣管線173可能會將一載送氣體(carrier gas)及前驅物氣體一起輸送到反應空間12內。而後透過閥件組將非反應氣體輸送至反應空間12內,並透過第二抽氣管線179抽氣,以去除反應空間12內的前驅物氣體。在本發明一實施例中,進氣管線
173可連接複數個分枝管線,並分別透過各個分枝管線將不同的前驅物氣體依序輸送至反應空間12內。
The
此外進氣管線173可增大輸送至反應空間12的非反應氣體的流量,並透過非反應氣體吹動反應空間12內的粉末121,使得粉末121受到非反應氣體的帶動,而擴散到反應空間12的各個區域。
In addition, the
在本發明一實施例中,進氣管線173可包括至少一非反應氣體輸送管線175流體連接真空腔體11的反應空間12,並用以將一非反應氣體輸送至反應空間12,例如非反應氣體輸送管線175可透過閥件組連接一氮氣儲存槽,並透過閥件組將氮氣輸送至反應空間12。非反應氣體用以吹動反應空間12內的粉末121,配合驅動單元15驅動真空腔體11轉動,可有效且均勻的翻攪反應空間12內的粉末121,並在各個粉末121的表面沉積厚度均勻的薄膜。
In an embodiment of the present invention, the
具快拆功能的粉末原子層沉積設備10的進氣管線173及非反應氣體輸送管線175都用以將非反應氣體輸送至反應空間12,其中進氣管線173輸送的非反應氣體的流量較小,主要用以去除反應空間12內的前驅物氣體,而非反應氣體輸送管線175輸送的非反應氣體的流量較大,主要用以吹動反應空間12內的粉末121。
Both the
具體而言,進氣管線173及非反應氣體輸送管線175將非反應氣體輸送至反應空間12的時間點不同,因此在實際應用時可不設置非反應氣體輸送管線175,並調整進氣管線173在不同時間點輸送的非反應氣體的流量。當要去除反應空間12內的前驅物氣體時,可降低進氣管線173輸送至反
應空間12的非反應氣體的流量,而要吹動反應空間12內的粉末121時,則增加進氣管線173輸送至反應空間12的非反應氣體的流量。
Specifically, the time points at which the
本發明的驅動單元15帶動外管體131及真空腔體11轉動時,內管體133及其內部的第一抽氣管線171、第二抽氣管線179、進氣管線173及/或非反應氣體輸送管線175不會隨著轉動,有利於提高進氣管線173及/或非反應氣體輸送管線175輸送至反應空間12的非反應氣體及/或前驅物氣體的穩定度。
When the driving
加熱器177用以加熱連接空間134及內管體133,並透過加熱器177加熱內管體133內的第二抽氣管線179、進氣管線173及/或非反應氣體輸送管線175,以提高第二抽氣管線179、進氣管線173及/或非反應氣體輸送管線175內的氣體的溫度。使得非反應氣體及/或前驅物氣體進入反應空間12時,不會造成反應空間12的溫度大幅下降或改變。此外亦可於連接空間134內設置一溫度感測單元用以量測加熱器177或連接空間134的溫度,以得知加熱器177的工作狀態。當然在真空腔體11的內部、外部或周圍通常會設置另一個加熱裝置,其中加熱裝置鄰近或接觸真空腔體11,並用以加熱真空腔體11及反應空間12。
The
在進行原子層沉積製程時,真空腔體11的反應空間12需要維持真空狀態,因此真空腔體11的結構通常較為厚實,重量亦較為沉重。軸封裝置13用以承載及驅動真空腔體11,同樣較為厚實及沉重。在操作時使用者需要將真空腔體11及軸封裝置13一起由驅動單元15上卸下,才能將真空腔體11內的粉末121取出,並清潔真空腔體11。如此一來不僅會造成使用者的
負擔,亦可能在操作及清潔過程中發生碰撞,而造成使用者受傷或裝置損壞。
During the atomic layer deposition process, the
為了改善上述的問題,本發明將真空腔體11及軸封裝置13設計為兩個獨立的構件。在進行原子層沉積時,可將真空腔體11連接軸封裝置13,如圖2所示,並於真空腔體11與軸封裝置13之間形成密閉空間16。而後透過第一抽氣管線171抽出密閉空間16內的氣體,使得密閉空間16為真空,以將真空腔體11固定在軸封裝置13上,而驅動單元15可透過軸封裝置13帶動真空腔體11轉動。當真空腔體11連接軸封裝置13時,軸封裝置13內的第二抽氣管線179、進氣管線173及/或非反應氣體輸送管線175會流體連接真空腔體11的反應空間12。
In order to improve the above problems, the present invention designs the
在完成原子層沉積後,可透過第一抽氣管線171卸除密閉空間16的真空,例如經由第一抽氣管線171將氣體輸送至密閉空間16,而後可將真空腔體11由軸封裝置13上卸下。

透過本發明所述的具快拆功能的粉末原子層沉積設備10,可快速將真空腔體11由軸封裝置13卸下,並將另一個真空腔體11裝設在軸封裝置13上。在拆卸及裝設真空腔體11的過程中僅須要透過幫浦經由第一抽氣管線171抽出密閉空間16內的氣體,或是經由第一抽氣管線171將氣體輸送至密閉空間16,而不需要透過螺絲鎖固真空腔體11及軸封裝置13,可大幅提高更換真空腔體11的速度及便利性。

在本發明一實施例中,軸封裝置13及/或真空腔體11之間可設置複數個密封環,其中密閉空間16位於兩個密封環之間,並透過密封環隔離密閉空間16及外界環境。具體而言,密封環包括一第一密封環161及一第二
密封環163,當真空腔體11連接軸封裝置13時,真空腔體11及軸封裝置13會壓迫兩者之間的第一密封環161及第二密封環163,並在第一密封環161及第二密封環163之間形成密閉空間16。如圖3所示,第一密封環161設置在真空腔體11上,而第二密封環163則設置在軸封裝置13上。
In an embodiment of the present invention, a plurality of sealing rings may be arranged between the
在實際應用時,第一密封環161位於內管體133及真空腔體11之間,而第二密封環163位於外管體131及真空腔體11之間,其中第一密封環161為一動態密封環,而第二密封環163為一靜態密封環。例如第一密封環161可套設在內管體133上,並為鐵氟龍O型環(Teflonoring),而第二密封環163則為橡膠製的O型環。
In practical application, the
在本發明一實施例中,如圖3所示,真空腔體11的底部112可設置一凹部114,並於凹部114內設置第一密封環161。軸封裝置13的內管體133部分凸出外管體131,並於軸封裝置13連接真空腔體11的底部112的一側設置第二密封環163,或者是在凸出的內管體133上套設第二密封環163。
In an embodiment of the present invention, as shown in FIG. 3 , a
凸出軸封裝置13的內管體133在徑向上的橫切面面積略小於真空腔體11的凹部114,當凸出的內管體133插入真空腔體11的凹部114時,凸出的內管體133會壓迫凹部114內的第一密封環161,而真空腔體11的底部112或凹部114則會壓迫設置在軸封裝置13上的第二密封環163,以在凸出的內管體133、凹部114、第一密封環161及/或第二密封環163之間形成密閉空間16。上述第一密封環161、第二密封環163及/或凹部114的數量及設置位置僅為本發明一具體實施例,並非本發明權利範圍的限制。
The cross-sectional area of the
本發明的第一抽氣管線171大致上沿著軸封裝置13的軸向設置,並具有沿著軸封裝置13的徑向的分枝或彎折,以在凸出軸封裝置13的內管
體133的側壁上形成一開口,使得第一抽氣管線171經由內管體133的側壁上的開口流體連接密閉空間16。

本發明所述的具快拆功能的粉末原子層沉積設備10亦有利於提高原子層沉積的製程效率。具體而言,可準備多個真空腔體11,並分別在各個真空腔體11內放置粉末121。將其中一個真空腔體11固定在軸封裝置13上,並對真空腔體11內的粉末121進行原子層沉積。在完成粉末121的原子層沉積後,將真空腔體11及粉末121由軸封裝置13卸下,並將另一個真空腔體11固定在軸封裝置13上,對該真空腔體11內的粉末121進行原子層沉積製程。被卸下的真空腔體11可放置在冷卻區,待真空腔體11及粉末121的溫度下降後,再將粉末121由真空腔體11內取出。

在本發明一實施例中,真空腔體11的底部112可設置一過濾單元139,例如過濾單元139可設置在真空腔體11的凹部114內。當真空腔體11連接軸封裝置13時,真空腔體11上的過濾單元139會覆蓋軸封裝置13的內管體133,使得內管體133內的第二抽氣管線179、進氣管線173及/或非反應氣體輸送管線175經由過濾單元139流體連接真空腔體11的反應空間12。
In an embodiment of the present invention, a
透過過濾單元139的設置,可避免第二抽氣管線179抽出反應空間12內的氣體時,將反應空間12內的粉末121一併抽出,造成粉末121的損耗。另外將過濾單元139設置在真空腔體11上,而非設置在軸封裝置13上,則可避免真空腔體11由軸封裝置13上卸下時,粉末121由真空腔體11的反應空間12散落到外部。
The arrangement of the
在本發明一實施例中,如圖5所示,進氣管線173及/或非反應氣體輸送管線175可由內管體133的連接空間134延伸至真空腔體11的反應空
間12,並在真空腔體11的反應空間12內形成一延伸管體172。延伸管體172的端部及/或管壁上可設置至少一出氣孔1721,延伸管體172可經由出氣孔1721將非反應氣體輸送至反應空間12,並吹動反應空間12內的粉末121。
In an embodiment of the present invention, as shown in FIG. 5 , the
在本發明一實施例中,凹部114可由真空腔體11的底部112延伸至反應空間12內,而軸封裝置13的內管體133則由外管體131的容置空間132延伸至外部,並凸出軸封裝置13及外管體131,如圖7所示。連接真空腔體11及軸封裝置13時,凸出軸封裝置13的內管體133可用以插入凹部114,並在內管體133及真空腔體11的凹部114之間形成密閉空間16,如圖6所示。此外,軸封裝置13的內管體133會由外管體131的容置空間132延伸至真空腔體11的凹部114及/或反應空間12,使得內管體133及凹部114在反應空間12內形成一凸出管部130。
In an embodiment of the present invention, the
透過凸出管部130的設置可縮短或調整進氣管線173及/或非反應氣體輸送管線175與蓋板111之間的距離,進氣管線173及/或非反應氣體輸送管線175輸送至反應空間12的非反應氣體可傳遞至蓋板111的內表面1111,並經由蓋板111的內表面1111擴散到反應空間12的各個區域,以利於吹動反應空間12內的粉末121。
