也可通過設置一活動支柱43,來調整測試組件40高度及 傾角。滑動支撐座32可沿外殼内壁之滑軌移動,以調整 測試晶片41之位置,從而可調整其相對於鍍膜源20之距 離;測試晶片41可採用石英測試晶片或光學玻璃測試晶 片,其利用石英震盪頻率之改變來初步監控工件12之鍍 膜厚度變化,並根據該厚度變化監測鍍膜源之鍍率。通 常,鍍膜源之鍍率維持在0. 5A*s_1左右,當測試組件40 監測之鍍膜速率偏離該數值時,即可調整鍍膜源20之電 壓或功率,以使鍍膜源20之鍍率達到預定要求。當鍍膜 源20採用多種鍍材時,也可於相應位置設置多個測試組 件40同時對鍍膜厚度進行初步監控,以減少操作誤差, 提高鍍膜過程之精度。 [0028] 鍍膜時,承載座11在旋轉軸13帶動下繞其轉動,使工件 12均勻鍍膜。當需要於工件12上鍍較厚薄膜時,即可縮 短監控晶片31相對於鍍膜源20之距離,即造成監控晶片 31之鍍膜厚度與欲鍍於工件上薄膜厚度之比值提高;反 094117367 表單編號A0101 第10頁/共19頁 1003263264-0 1352128 100年07月20日修正替换頁 之亦然。因而,在本實施例中,‘監控晶片31相對於鍍膜 源20之位置可與工件12相對於鍍膜源20之位置相近似, 亦可高於或低於工件12相對於鍍膜源20之位置。鍍膜設 備1特別適應於多層鍍膜,當每層薄膜厚度不一時,按上 述方法相應地調整監控晶片31之位置,以使其適應新鍍 膜層厚度之需求,於工件12上鍍得相應厚度之薄膜層。 如對於一紫外濾光片,為提高紫外波段截止效果,通常 需於基底鍍上30層以上薄膜,每層薄膜厚度變化範圍在 100nm~200nm左右,此時需不斷調整監控晶片31之位置 ,以利於其對工件12上不同厚度之鍍膜進行即時監控。 [0029] 請參閱第三圖,係本技術方案提供之鍍膜方法流程圖。 該鍍膜方法包括以下步驟:提供一鍍膜源;將複數欲鍍 膜之工件置於與鍍膜源相對設置之承載裝置之複數承載 座上;對工件鍍膜,同時調整一監控裝置中監控晶片相 對於鍍膜源之距離,來改變監控晶片之鍍膜厚度與工件 欲鍍膜厚度所成之比值,以利於監控晶片監控工件上欲 鍍膜厚度;重複前一步驟,直到工件鍍上預定厚度之薄 膜。 [0030] 步驟100 :提供一鍍膜源。該鍍膜源20係可採用蒸鍍源、 濺鍍源、靶材等,當需鍍多層薄膜時,其通常包含多種 材質,因而,鍍膜源可相應包括多種材質之鍵膜源,則 鍍膜源20可採用多個鍍源或靶頭。 [0031] 步驟200 :將複數欲鍍膜之工件置於與鍍膜源相對設置之 承載裝置之複數承載座上。通常,為保持該等工件鍍膜 均勻一致性,該等承載座11均勻分佈於承載平台14上, 094117367 表單編號A0101 第11頁/共19頁 1003263264-0 1352128 100年07月20日核正替換頁 而對於欲鍍相同厚度膜層之工件12,可將其設置於對稱 的承載座11上。 [0032] 步驟300 :對工件鍍膜,同時調整一監控裝置中監控晶片 相對於鍍膜源之距離,來改變監控晶片之鍍膜厚度與工 件欲鍍膜厚度所成之比值,以利於監控晶片監控工件上 欲鍍膜厚度。開始鍍膜時,通過監控裝置30中之監控晶 片31來監控工件12上鍍膜厚度,由於監控晶片之鍍膜厚 度與工件欲鍍膜厚度成一定比值,通過該比值可得出監 控晶片31相對於鍍膜源20之距離,調整成相應位置後, 即可利用監控晶片31監控鍍膜厚度。如工件12欲鍍膜厚 度增大時,使得該比值增加,即可相應縮短所述監控晶 片31相對於鍍膜源20之距離,以利於其對工件12鍍膜厚 度之監控;同樣,工件12欲鍍膜厚度較低時,使得該比 值減小,即可相應增加監控晶片31相對於鍍膜源之距離 ,以利於其對工件12鍍膜厚度之監控。通過監控晶片31 之此種即時監控,可精密控制工件12之鍍膜厚度。 [0033] 步驟400 :重複前一步驟,直到工件鍍上預定厚度之薄膜 。通常,工件12上需鍍多層薄膜,當工件12通過上述步 驟鍍上一層薄膜後,接著進行下一層鍍膜時,該膜層厚 度通常與上一層薄膜厚度不同,此時只需重複步驟300, 使監控晶片31仍然能監控工件12欲鍍膜厚度,於其上鍍 新的膜層。如此,不論需於工件12上鍍多少層薄膜,其 厚度儘管各不相同,通過本實施例提供之鍍膜方法即可 滿足預定厚度鍍膜要求。欲鍍膜有時需鍍上不同材質膜 層時,還要更換成相應鍍源。 094117367 表單編號A0101 第12頁/共19頁 1003263264-0 Γ352128 100年07月20日修正替換頁 [0034] 另,鍍膜方法還可包括利’用一測試組件40初步監控工件 12鍍膜厚度及鍍膜源20鍍率之步驟;測試組件40至少包 括一能動態調整之測試晶片41,其可採用石英晶片或光 學玻璃晶片。 [0035] 本實施例提供之鍍膜設備1具有一可動態滑動之監控晶片 31,當欲鍍工件固定時,通過動態調整監控晶片31相對 於鍍膜源20之距離,從而可改變監控晶片31之鍍膜厚度 與欲鍍於工件12上薄膜厚度之比值,使監控晶片適應於 監控新的欲鍍膜厚度。因而,本實施例之鍍膜設備可適 應膜厚多樣化之產品,特別適用於多層鍍膜。而且上述 比值在實際應用中較易於精密控制,能通過動態調整監 控晶片31相對於鍍膜源20之距離,使監控晶片31能即時 對工件不同厚度之鍍膜進行精確控制。另,由於本實施 例還結合一可動態滑動之測試組件40,利用其初步監控 鍍膜厚度以及鍍膜源20之鍍率,以利於監控晶片31進一 步對工件12鍍膜厚度進行精密控制。 [0036] 综上所述,本發明符合發明專利之要件,爰依法提出專 利申請。惟,以上所述者僅為本發明之較佳實施例,自 不能以此限制本案之申請專利範圍。舉凡熟悉本案技藝 之人士,在援依本案發明精神所作之等效修飾或變化, 皆應包含於以下之申請專利範圍内。 【圖式簡單說明】 [0037] 第一圖係本技術方案實施例之鍍膜設備示意圖。 [0038] 第二圖係本技術方案實施例之鍍膜設備中承載裝置仰視 圖。 表單編號A0101 094117367 第13頁/共19頁 1003263264-0 1352128 [0039] [0040] [0041] [0042] [0043] [0044] [0045] [0046] [0047] [0048] [0049] [0050] [0051] [0052] [0053] [0054] [0055] 100年07月20日核正替換 第三圖係本技術方案實施例之鍍膜方法流程圖。 【主要元件符號說明】 鍍膜設備:1 承載座:11 旋轉韩:13 承載圓週:15 監控裝置:30 滑動元件:32 測試晶片.41 活動支柱:4 3 承載裝置:10 工件:12 承載平台:14 鍍膜源:20 監控晶片:31 測試組件:40 滑動支撐座:42 真空腔體:50 094117367 表單编號A0101 第14頁/共19頁 1003263264-01352128 100 years Ό July 2nd day L------------- VI. Description of the invention: [Technical field of invention] [0001] The present invention relates to the field of thin film processing, and more particularly to plating Coating equipment for coating thickness monitoring function and coating method thereof. [Prior Art] [0002] At present, thin film process technology is widely used in the semiconductor industry and precision machinery. 'Because of the high added value of the products produced by the thin film process technology, the thin film process technology and film materials are widely used in research and Practice, while bringing the rapid development of key film technology. Generally, the key 貘 method mainly includes ion plating method, radio frequency magnetron sputtering, vacuum evaporation method, and chemical vapor deposition method. However, with the intensive and miniaturized integrated circuit, the precision of precision machinery is increasing, and the thickness of the coating is increasingly demanding. For example, some filter films require as many as dozens of layers, which makes film thickness monitoring a major challenge. [0003] For film coating thickness monitoring, optical monitoring is a preferred monitoring method commonly used in high-precision coating process, and is divided into direct monitoring on the workpiece or indirectly on a separate monitoring test piece, the latter is flexible. If a quartz monitor wafer is used to monitor and measure the thickness of the coating, it can monitor the thickness of the deposited film in real time. The basic principle is that a certain mass of material is deposited on the quartz wafer, and the resonance frequency is changed: Af = _ 2 2f 〇 Δm / ACup / · 5: ; where, is the initial resonant frequency of the quartz wafer; A is the surface area; p is the density of quartz (2 · 648gcm 3). In this formula, c is a constant related to quartz crystal, which will remain unchanged during the coating process; then within a certain range, the change of the resonant frequency of the quartz wafer and the change in the amount of Moir deposited on the surface are linear 094117367. Form No. A0101 Page 4 of 19 Page 1003263264-0 Correction of the replacement page 1352128 on July 20, 100; thus, the film thickness deposited on the surface of the quartz wafer can be monitored by monitoring the change in the resonant frequency of the quartz wafer. [〇〇〇4] The prior art provides a coating apparatus comprising a motor; a first gear, the shaft is disposed at an axis of the motor; and at least two second gears respectively meshing with the first gear; At least two substrate carriers are respectively disposed on the axis of each of the second gears; a spacer is disposed between the second gears and the substrate carriers, and at least one side of the spacers Providing two shutter brackets, one end of each shutter bracket is fixed to the partition plate, and the other end portion thereof is extended toward the direction in which the substrate carrier is disposed; and a coating source is connected to the substrates The carrier is opposite. The optical monitoring unit of the coating device is adjacent to one of the substrate carriers. The method only obscures the thin area to be coated by the shutter, thereby producing a film layer having a discontinuous thickness, which is a control of the discontinuous thickness of the single layer film. Generally, for different optical components, the corresponding design film thickness requirement is required. Unlike the limited monitoring wavelength range, the thickness of the coating can be monitored, which makes it difficult to meet the diversified thickness of the multilayer film, and it is difficult to precisely control the thickness of the various films. In view of the above, it is necessary to provide a coating apparatus that can be applied to a variety of coating thicknesses and is easy to precisely control. SUMMARY OF THE INVENTION [0006] Hereinafter, a coating apparatus which can be applied to a variety of coating thicknesses and which is easy to precisely control will be described with reference to a number of embodiments. [0007] A method of coating is described by way of examples.

[0009] Wherein, the coating device further comprises at least one test component disposed opposite the coating source and disposed between the coating source and the carrier. [0010] The test component includes at least one dynamically adjustable test wafer; the test wafer is a center wafer or an optical glass wafer. The ratio is between 0. 8~2. The ratio of the ratio of the thickness of the coating film to the thickness of the coating film is inversely proportional to the distance of the surface of the coating film. [0012] the carrying device adopts an umbrella-type or planetary-type carrying device; and the plurality of carrying seats are evenly distributed on the surface of the umbrella-type carrying device relative to the coating source or the surface of the planetary carrier relative to the coating source . [0013] Also, a coating method comprising the following steps: 094117367 Form No. 101 0101 Page 6 / Total 19 Page 1003263264-0 1352128 100 July 20th Shuttle Replacement Page [0014] A coating apparatus as described above is provided; [0015] placing a plurality of workpieces to be coated on a plurality of carriers of the carrier device t [0016] coating the workpiece and the monitor wafer while adjusting axial sliding of the sliding member along the rotating shaft Adjusting the distance of the monitoring wafer relative to the coating source, thereby changing the ratio of the coating thickness of the monitoring wafer to the thickness of the workpiece to be coated, thereby facilitating monitoring of the workpiece on the workpiece by the monitoring wafer Thickness; [0017] The previous step is repeated until the workpiece is plated with a film of a predetermined thickness. [0018] wherein the coating method further comprises initially monitoring the thickness of the workpiece coating and the plating rate of the coating source by using a test component; the testing component comprises at least a dynamically adjustable test wafer; and the quartz wafer or the optical glass wafer is used. [0019] when the thickness of the workpiece to be coated is increased, the distance between the monitoring wafer and the coating source is reduced, so that the ratio of the coating thickness of the monitoring wafer to the coating thickness of the workpiece is increased; the thickness of the workpiece to be coated is decreased. The ratio of the thickness of the coating film to the coating thickness of the workpiece is reduced; the ratio is between 0. 8 and 2 [0020] and the prior art In contrast, the coating apparatus provided in this embodiment has a dynamically slidable monitoring wafer. When the workpiece to be plated is fixed, the thickness of the coating on the monitoring wafer is adjusted by dynamically adjusting the distance of the wafer relative to the coating source to change the monitoring. The ratio of the thickness of the wafer to the thickness of the film to be plated on the workpiece, so that the monitor wafer is adapted to monitor the new thickness of the coating 094117367.

[0021] The coating method provided by the embodiment utilizes the device to dynamically slide the monitoring wafer. During the coating process, the distance between the monitoring wafer and the coating source can be adjusted, so that the coating thickness of the workpiece can be monitored in real time to realize the workpiece coating. Precision control of thickness. [Embodiment] [0023] The present invention will be further described in detail below with reference to the accompanying drawings. Please refer to the first figure and the second figure together to provide a schematic diagram of the structure of the coating device and the carrying device provided by the embodiment of the technical solution. The coating device 1 comprises a workpiece carrier 10 having a plurality of carriers 11 for carrying a workpiece 12 to be plated; a coating source 20 opposite the workpiece carrier 10; and a monitoring device 30 Opposite to the coating source 20, the distance from the coating source 20 can be adjusted correspondingly with the thickness variation of the coating to change the ratio of the coating thickness of the monitor wafer 31 to the coating thickness of the workpiece 12 in the monitoring device. The coating apparatus 1 may further include at least one test assembly 40 disposed opposite the coating source 20 and disposed between the coating source and the carrier. The entire coating apparatus 1 can be placed in a vacuum chamber 50. [0024] The carrying device 10 may adopt an umbrella type or a planetary structure. This embodiment employs a planetary structure. The carrying device 10 has a rotating shaft 13 and a carrying platform 14, and the plurality of carrying seats 11 are disposed on the carrying platform 14 and evenly distributed on the bearing circumference 15 094117367 of a certain radius centered on the rotating shaft 13 or The multi-layer is surrounded by the circumference of the rotating shaft 13; the half of the carrying circle 15 is the form number A0101, the eighth page, the total of 19 pages, 1003263264-0, the correction of the replacement page 1352128, the number of the bearing seats 11 When there are few, the radius is correspondingly small; when the number of the carrier 11 is large, the radius is correspondingly increased, so that the carriers 11 can be evenly arranged, so that more workpieces 12 can be coated at the same time. In this embodiment, two load-bearing circumferences 15 are used, which have a total of 24 load-bearing seats 11 on which a workpiece 12 to be coated is respectively carried. [0025] The coating source 20 is disposed opposite to the carrier device 10; the coating source may be a vapor deposition source or a sputtering source 'target. When a multi-layer film is to be applied, it usually contains a plurality of film materials. Therefore, the film source can include a plurality of film sources, and the film source 20 can use a plurality of plating sources or targets. The monitoring device 30 may include a monitoring wafer 31 and a sliding member 32; the monitoring wafer 31 may be a quartz wafer or an optical glass wafer; the sliding member 32 may be axially slid along the rotating shaft 13 to adjust the position of the monitoring wafer 31, Thereby, the distance of the monitor wafer 31 with respect to the coating source 20 is dynamically adjusted. In this embodiment, the monitoring wafer 31 and the workpiece 12 are both disposed opposite to the coating source 20. While the workpiece 12 is coated, the monitoring wafer 31 is also plated with a certain thickness of film, thereby monitoring the coating thickness of the wafer 31 and the workpiece 12 The thickness of the coating is a certain ratio. Generally, when the coating time is constant, the thickness of the coating layer of the monitor wafer 31 and the workpiece 12 is inversely proportional to the distance from the coating source 20, that is, the closer the wafer 31 and the workpiece 12 are to the coating source 20, the coating layer thereon. The thicker, thus, when the workpiece 12 is fixed in position, the coating thickness ratio of the monitor wafer 31 and the workpiece 12 can be adjusted by the distance of the monitor wafer 31 from the coating source 20. If the workpiece 12 is plated with a certain thickness of the single layer film, according to the ratio of the thickness of the coating wafer 31 and the workpiece 12, the thickness of the coating on the workpiece 12 is indirectly controlled by the monitoring wafer 31 to monitor the thickness of the coating itself; When plating a multilayer film, as described above, 094117367 Form No. A0101 Page 9/19 pages 1003263264-0 1352128 100 July 20th After the first film is plated, the thickness of the second film layer is When changing, the distance between the monitoring wafer 31 and the coating source 20 is adjusted. When the thickness is thicker, the distance is adjusted to make the ratio of the coating thickness of the monitoring wafer 31 and the workpiece 12 suitable, usually between 0.8 and 2, to facilitate monitoring the wafer 31. The thickness of the coating itself is monitored, that is, the precise control of the thickness of the coating 12 is achieved. The monitoring wafer 31 can adopt one or more wafers. For a simple coating, a single monitoring wafer 31 can meet the requirements; if the coating source 20 uses a plurality of plating materials, a plurality of monitoring wafers 31 can be used, which respectively correspond to the coating material. [0027] The test assembly 40 can include a test wafer 41 and a sliding support 42; the height and tilt of the test assembly 40 can also be adjusted by providing a movable post 43. The sliding support base 32 is movable along the slide rail of the inner wall of the outer casing to adjust the position of the test wafer 41 so as to adjust its distance from the coating source 20; the test wafer 41 can be a quartz test wafer or an optical glass test wafer using quartz. The change in the oscillation frequency is used to initially monitor the change in coating thickness of the workpiece 12, and the plating rate of the coating source is monitored based on the thickness variation. Generally, the plating rate of the coating source is maintained at about 0.5 A*s_1. When the coating rate monitored by the test component 40 deviates from the value, the voltage or power of the coating source 20 can be adjusted to achieve the plating rate of the coating source 20. Claim. When the coating source 20 is made of a plurality of plating materials, a plurality of test components 40 may be disposed at corresponding positions to simultaneously monitor the thickness of the coating to reduce the operation error and improve the precision of the coating process. [0028] When the film is coated, the carrier 11 is rotated around the rotating shaft 13 to uniformly coat the workpiece 12. When it is required to plate a thick film on the workpiece 12, the distance between the monitoring wafer 31 and the coating source 20 can be shortened, that is, the ratio of the coating thickness of the monitoring wafer 31 to the thickness of the film to be plated on the workpiece is increased; and the 094117367 form number A0101 Page 10 of 19 1003263264-0 1352128 The revised replacement page is also available on July 20, 100. Thus, in the present embodiment, the position of the monitor wafer 31 relative to the coating source 20 may be similar to the position of the workpiece 12 relative to the coating source 20, and may be higher or lower than the position of the workpiece 12 relative to the coating source 20. The coating device 1 is particularly suitable for multi-layer coating. When the thickness of each film is different, the position of the monitoring wafer 31 is adjusted accordingly according to the above method to adapt to the thickness of the new coating layer, and the film of the corresponding thickness is plated on the workpiece 12. Floor. For an ultraviolet filter, in order to improve the ultraviolet band cut-off effect, it is usually necessary to plate more than 30 films on the substrate, and the thickness of each film varies from about 100 nm to about 200 nm. At this time, the position of the monitor wafer 31 needs to be constantly adjusted to It facilitates immediate monitoring of coatings of different thicknesses on the workpiece 12. [0029] Please refer to the third figure, which is a flow chart of a coating method provided by the technical solution. The coating method comprises the steps of: providing a coating source; placing a plurality of workpieces to be coated on a plurality of carriers of the carrying device disposed opposite to the coating source; coating the workpiece while adjusting a monitoring device in the monitoring device relative to the coating source The distance is changed to change the ratio of the coating thickness of the monitor wafer to the thickness of the workpiece to be coated, so as to facilitate monitoring of the wafer thickness on the workpiece. The previous step is repeated until the workpiece is plated with a predetermined thickness. [0030] Step 100: providing a coating source. The coating source 20 can be an evaporation source, a sputtering source, a target, etc. When a multilayer film is to be plated, it usually contains a plurality of materials. Therefore, the coating source can include a plurality of material bond source sources, and the coating source 20 Multiple plating sources or targets can be used. [0031] Step 200: placing a plurality of workpieces to be coated on a plurality of carriers of a carrier disposed opposite the coating source. Generally, in order to maintain the uniformity of the coating of the workpieces, the carriers 11 are evenly distributed on the carrying platform 14, 094117367 Form No. A0101 Page 11 / 19 pages 1003263264-0 1352128 100 July 20th Nuclear Replacement Page For the workpiece 12 to be plated with the same thickness, it can be placed on the symmetrical carrier 11. [0032] Step 300: coating the workpiece, and adjusting the distance of the monitoring wafer relative to the coating source in a monitoring device to change the ratio of the coating thickness of the monitoring wafer to the thickness of the workpiece to be coated, so as to facilitate monitoring of the wafer to monitor the workpiece. Coating thickness. When the coating is started, the thickness of the coating on the workpiece 12 is monitored by the monitoring wafer 31 in the monitoring device 30. Since the coating thickness of the monitoring wafer is proportional to the thickness of the workpiece to be coated, the ratio of the monitoring wafer 31 to the coating source 20 can be obtained by the ratio. After the distance is adjusted to the corresponding position, the thickness of the coating can be monitored by the monitor wafer 31. If the thickness of the workpiece 12 is to be increased, the ratio is increased, and the distance between the monitor wafer 31 and the coating source 20 can be shortened correspondingly to facilitate monitoring of the coating thickness of the workpiece 12. Similarly, the thickness of the workpiece 12 is desired. When the ratio is lower, the ratio is reduced, and the distance between the monitor wafer 31 and the coating source is increased correspondingly to facilitate the monitoring of the coating thickness of the workpiece 12. By monitoring such instant monitoring of the wafer 31, the coating thickness of the workpiece 12 can be precisely controlled. [0033] Step 400: Repeat the previous step until the workpiece is plated with a film of a predetermined thickness. Generally, the workpiece 12 is coated with a multi-layer film. When the workpiece 12 is coated with a film through the above steps, and then the next layer is coated, the film thickness is usually different from the thickness of the upper film. The monitor wafer 31 is still capable of monitoring the thickness of the workpiece 12 to be coated and plating a new layer thereon. Thus, no matter how many layers of film are to be plated on the workpiece 12, although the thicknesses thereof are different, the coating method provided by the embodiment can satisfy the predetermined thickness coating requirements. If the coating is to be plated with different material layers, it must be replaced with the corresponding plating source. 094117367 Form No. A0101 Page 12 of 19 1003263264-0 Γ352128 Correction Replacement Page of July 20, 100 [0034] In addition, the coating method may further include initially monitoring the coating thickness and coating source of the workpiece 12 with a test component 40. The step of 20 plating rate; the test assembly 40 includes at least one dynamically adjustable test wafer 41, which may be a quartz wafer or an optical glass wafer. [0035] The coating apparatus 1 provided in this embodiment has a dynamically slidable monitoring wafer 31. When the workpiece to be plated is fixed, the distance between the wafer 31 and the coating source 20 can be dynamically adjusted, thereby changing the coating of the monitoring wafer 31. The ratio of the thickness to the thickness of the film to be plated on the workpiece 12 allows the monitor wafer to be adapted to monitor the thickness of the desired coating. Therefore, the coating apparatus of the present embodiment can be applied to a product having a wide film thickness, and is particularly suitable for a multilayer coating. Moreover, the above ratio is easier to precisely control in practical applications, and the distance between the wafer 31 and the coating source 20 can be dynamically adjusted, so that the monitoring wafer 31 can accurately control the coating of different thicknesses of the workpiece. In addition, since the present embodiment further incorporates a dynamically slidable test assembly 40, the thickness of the coating film and the plating rate of the coating source 20 are initially monitored to facilitate the monitoring wafer 31 to further precisely control the coating thickness of the workpiece 12.
