Description of the Invention: [Technical Field] The present invention relates to image sensors, and more particularly to a color filter and light array for improving color symmetry of an image sensing device (color Filter array).
I 【先前技術】 影像感測裝置為當今如數位相機、行動電話以及玩 具等眾多光電裝置内之必要構件之一。習知影像感測裝 置則包括電编合裝置（charge coupled device，CCD)影像感 測裝置與互補型金氧半導體（complementary metal oxide oxide, CMOS)影像感測裝置。 影像感測裝置通常包括了平面陣列化之複數個像素 胞（pixel cells)，其中各像素胞包括了一光電管 (photogate)、一光導體(photoconductor)或具有用於累積光 電電荷用之摻雜區的一感光二極體(photodiode)。 於此平面陣列化之像素胞上則疊設有由不同色彩之 染料所構成之週期性圖樣(periodic pattern)。上述之週期 性圖樣即為習知之彩色濾光陣列（color filter array)。於李； 色濾、光陣列上則疊設有複數個微透鏡(microlens)。利用圓 形或方形之微透鏡可聚焦入射光於各像素胞内之電荷累、 積區處。藉由收集來自廣大之光線收集區的光線教將之 透過影像感測裝置微透鏡而聚焦於一小的感光區處可顯 著地改善了影像感測器之感測度。 ' 〇978-A32882TWF/VIP2007-002/ShawnChai 200905870 第1圖與第2圖等之示意圖 於US 6,995，_號專利中f _ 、了由Takahashi等人 10。第1 FI A曰旨- 句不之一習知影像感測裝置 弟1圖為痛'不了影像感測 面圖，而第2® — “了ϋ i /像素群組的平 二;:：…與第五行c等處像素剖面情形之一 不-、圖。如第i圖與第2圖所示 ： 層内形成有一像素i，苴内且有.χ & 8之—表面 元件5。遮光層離有、上有广二極體/光繼 邱八戸,，、有遮先區，以遮蔽各像素1内之 i:; 2 I感光二極體/光電轉換元件5之區域。 =Γ:成有一開口區3,以使得光線15可穿透 並入射至感光二極體/光電轉換元件5處。微透 ΓΓ:]將光線15聚集至感光二極體/光電轉換 :)箄二了色濾光層6則例如為具有紅(R)、綠(G)、藍 ()專色杉或其他色彩之濾光層。基於解說㈣，於第！ 、==示為5x5像素陣列為例，然而實際上於影像感 ，、衣 内可旎為包括依照二維模式排列之數百χ數百 之畫素陣列。 如第1圖與第2圖所示，設置於鄰近周邊區之像素】 較設置於晝素群組中心區之像素！具有感光二極體/光電 轉換兀件5之受光區（light recepti〇n regi〇n)的重心（^加灯 of gravity)較其内開口區3與微透鏡4之重心而更鄰近周 邊區之設置情形。因此，光線15之光軸2G可藉由微透 鏡4聚焦後而與感光二極體/光電轉換元件5之受光區 (light reception regi〇n)的重心（cemer 〇f gravity)之重心相 〇978-A32882TWF/VIP2〇〇7-〇〇2/ShawnChang 6 200905870 符合。 更精確的說，於第一行A内之傻+彳φ ^ , π ^ n1豕京1中，對應於如 乐1圖中所述之感光二極體/光電轉換元件5之受光區 :心，微透鏡4與開口區3之重心係設置於其右侧。而 之像素1中，對應如第1圖所述之於感光二極 光電轉換元件5之受光區之重心，微透鏡4與開口區 3之重心係設置於其中心處。而第五行c内之晝素}中， 對應於感光二極體/光電轉換元件5之受光區^重心，微 透鏡4與開口區3之重心係設置於其左側。 ' 如前所述，由於設置於鄰近周邊區之像素丨較設置 於晝素群組中心區之像素i具有感光二極體/光電轉換元 件5之受光區（light reception regi〇n)的重心（^加打 gravity)較其内開口區3與微透鏡4之重心而更鄰近周邊 區之設置情形。因此，當光線15穿透微透鏡4並入射至 感光二極體/光電轉換元件5處時並不會被遮光層2之遮 光區所攔戴。如此，位於如第丨·圖與第2圖所示影像感 測裝置之不同位置處之此些像素之輸出訊號之最大值與 最小值間的差距可因而縮減至低於輸出訊號平均值之 10%。上述表現係起因於聚集至感光二極體之光線並不會 為遮光層2所攔截，因而縮減了受光敏感度之變異量。 如第1圖與第2圖内所示之影像感測裝置1 〇内之彩 色濾光層6通常如第3圖所示之採用了包括如紅（R)、藍 (B)與綠（G)等不同色彩染料所構成之週期性圖樣 (periodic pattern)之二維彩色濾光陣列（2_d c〇i〇r filter 0978-A32882TWF/VIP2007-002/ShawnCliang 200905870 array)。如第3圖所示之週期性圖樣通稱為拜耳圖樣 (Bayer pattern)，其包括紅、藍、綠等三種色彩滤光物。 此外’如第4圖所示’如第}圖與第2圖内所示之影像 m置ίο内之彩色濾、光層6亦可採用包括青藍（c卿, Cy)、洋紅(magenta，Mg與黃（yeu〇w, Ye)等不同色彩染料 所構成色彩濾、光物所組成之週難圖樣的二維彩色滤光 陣列。 雖然第1圖所示之相對位置設置情形有助於改善了 影像感測裝置内之不同位置處間之像素處之輸出訊號的 變異值。然而，於具有相似於第！圖與第2圖所示之影 像感測裝置結構之影像感測裝置仍存在有如色散（c〇i〇r separation)現象之問題。色散現象可於晶片探針（chip Pr〇be)測試時經由—準直白色光（C〇nimated white light) 檢測一影像感測裝置時所發現。基於線路繞線以及其他 元件設計需求，感光二極體或光電轉換元件5内可能為 一不規則圖樣（irregular pattern)而非一徑向對稱圖樣 (radially symmetrical pattern)，如此於影像感測裝置内便 I能產生了色散現象。當影像感測裝置内具有色散現象 時，其可能造成採用此影像感測裝置之光電裝置内產生 影像遮蔽（image shielding)現象，因而於其上可能呈現不 正常之影像。 附件1與附件2為具有相似於如第〗圖所示結構之 一影像感測裝置的模擬影像，此時影像感測裝置^採用 了具有如第3圖所示拜耳圖樣之—彩色濾光層。附件i 0978-A32882TWF/VIP2007-002/ShawnChang 8 200905870 與附件2内之影像係於曰 、 射所得到之模擬影像，其 采針測忒知採用準直白光照 内之感光二極體/光鐘、附件1顯示了影像感測裝置 於X軸上不對稱）之/、有早一軸不對稱性（如 感測裝置内之感光二接附件2則顯示了影像 對稱性（如於x軸上蛊 :、兀件具有兩軸向上不 如附件丨所_ Ή上白不對稱）之—模擬影像。 不，枳擬影像中顯示了影像;^、別壯w 部呈現偏紅影像而A e b像饮測裝置上 形。而如附件2所：^ 之不均勾影像輪廓情 午2所不’模擬影像中則 測裝置左上部呈現偏紅 了於衫像感 呈現偏藍影像以及於m : &/貝1衣置之右下部 银&妹忠你 像感測裝置之右上部與左下部呈 現偏綠影像之不均句之影像輪廓情形。如附件！幻之 ==輪輪即為前述之，，色散，，現象，且為影像 置中所不期望出現之-不良情形。於具有色散現 象之衫像感測I置的光電裝置中將導致影像遮蔽㈣％ shielding)情形的發生。 【發明内容】 有鑑於此’本發明提供了一種彩色濾、光陣列及其應 用之影像感測裝置，以解決習知問題。 依據一實施例，本發明之彩色濾光陣列包括：一二維 陣列圖樣，包括：複數個第一色彩濾光物；複數個第二 色彩濾光物；以及複數個第三色彩濾光物，其中該些第 一色彩濾光物、該些第二色彩濾光物與該些第三色彩濾 0978-A32882TWF/VIP2007-002/ShawnChang 9 200905870 光物係週期性地排列，其中至少於該二維陣列圖樣内之 一第一區域内之該些第一色彩濾光物、該些第二色彩濾 光物與该些第二色彩濾光物與於該二維陣列圖樣内之一 第一區域内之該些第一色彩濾光物、該些第二色彩濾光 物與該些第三色彩濾光物係鏡像地對稱。I [Prior Art] Image sensing devices are one of the necessary components in many optoelectronic devices such as digital cameras, mobile phones, and toys. Conventional image sensing devices include a charge coupled device (CCD) image sensing device and a complementary metal oxide oxide (CMOS) image sensing device. The image sensing device generally includes a plurality of pixel cells planarly arrayed, wherein each pixel cell includes a photogate, a photoconductor or a doped region for accumulating photocharges. A photodiode (photodiode). A periodic pattern of dyes of different colors is superimposed on the pixel cells of the planar array. The above periodic pattern is a conventional color filter array. Yu Li; color filter, light array is stacked with a plurality of microlenses (microlens). A circular or square microlens can be used to focus the incident light at the charge accumulation region within each pixel cell. Focusing on a small photosensitive area through the image sensing device microlens by collecting light from a large collection area can significantly improve the sensitivity of the image sensor.

As shown in the i-th and the second figure: a pixel i is formed in the layer, and there is a surface element 5 in the 苴 & The layer is separated from the upper polarized body/lighted by Qiuqiu, and has a masking area to shield the area of i:; 2 I photosensitive diode/photoelectric conversion element 5 in each pixel 1. =Γ: An open area 3 is formed so that the light 15 can penetrate and be incident on the photosensitive diode/photoelectric conversion element 5. The micro-transmission:] concentrates the light 15 to the photosensitive diode/photoelectric conversion:) The filter layer 6 is, for example, a filter layer having red (R), green (G), blue () spot color fir or other colors. Based on the explanation (4), the first and the == 5x5 pixel arrays are taken as an example. However, in fact, in the sense of image, the inside of the clothes can be represented by a array of hundreds of pixels arranged in a two-dimensional mode. As shown in Figures 1 and 2, the pixels disposed adjacent to the peripheral area are compared. Set on The pixel of the central group of the element group! The center of gravity of the light-receiving element (light recepti〇n regi〇n) of the photodiode/photoelectric conversion element 5 is smaller than the inner opening area 3 and the microlens 4 The center of gravity is closer to the setting of the peripheral area. Therefore, the optical axis 2G of the light 15 can be focused by the microlens 4 and the center of gravity of the light receiving unit/photoelectric conversion element 5 (light reception regi〇n) The focus of (cemer 〇f gravity) is 978-A32882TWF/VIP2〇〇7-〇〇2/ShawnChang 6 200905870. More precisely, in the first line A, silly +彳φ ^ , π ^ n1豕In Beijing 1, corresponding to the light receiving region of the photosensitive diode/photoelectric conversion element 5 as described in the diagram of the music: the center of gravity of the microlens 4 and the open region 3 is disposed on the right side thereof, and in the pixel 1 Corresponding to the center of gravity of the light receiving region of the photosensitive diode photoelectric conversion element 5 as described in Fig. 1, the center of gravity of the microlens 4 and the open region 3 is disposed at the center thereof, and in the pixel of the fifth row c, Corresponding to the center of gravity of the light receiving region of the photodiode/photoelectric conversion element 5, the center of gravity of the microlens 4 and the open region 3 is set The left side. 'As mentioned above, since the pixels disposed in the adjacent peripheral area are larger than the pixels i disposed in the central area of the pixel group, the light receiving area of the photosensitive diode/photoelectric conversion element 5 (light reception regi〇n) The center of gravity (^gravity) is closer to the peripheral region than the center of gravity of the inner opening region 3 and the microlens 4. Therefore, when the light 15 penetrates the microlens 4 and is incident on the photosensitive diode/photoelectric conversion element At 5 o'clock, it will not be blocked by the shading area of the shading layer 2. Thus, the difference between the maximum value and the minimum value of the output signals of the pixels located at different positions of the image sensing device as shown in FIG. 2 and FIG. 2 can be reduced to 10 below the average value of the output signal. %. The above expression is caused by the fact that the light collected to the photosensitive diode is not intercepted by the light shielding layer 2, thereby reducing the variation of the light receiving sensitivity. The color filter layer 6 in the image sensing device 1 shown in FIGS. 1 and 2 is generally used as shown in FIG. 3 to include, for example, red (R), blue (B), and green (G). A two-dimensional color filter array of a periodic pattern composed of different color dyes (2_d c〇i〇r filter 0978-A32882TWF/VIP2007-002/ShawnCliang 200905870 array). The periodic pattern as shown in Fig. 3 is generally referred to as a Bayer pattern, which includes three color filters of red, blue, and green. In addition, as shown in Fig. 4, the color filter and the light layer 6 in the image m shown in Fig. 4 and Fig. 2 may also include blue (cqing, Cy) and magenta (magenta, Two-dimensional color filter arrays composed of different color dyes such as Mg and yellow (yeu〇w, Ye), which are composed of color filters and light objects. Although the relative position setting shown in Fig. 1 helps to improve The variation of the output signal at the pixel between different positions in the image sensing device. However, there is still an image sensing device having a structure similar to that of the image sensing device shown in Fig. 2 and Fig. 2 Dispersion (c〇i〇r separation) problem. Dispersion can be found when detecting an image sensing device via C〇nimated white light during chip probe testing. According to the line winding and other component design requirements, the photosensitive diode or the photoelectric conversion element 5 may be an irregular pattern rather than a radially symmetrical pattern, so that the image sensing device I can produce color inside Phenomenon, when there is dispersion in the image sensing device, it may cause image shielding phenomenon in the photoelectric device using the image sensing device, and thus may present an abnormal image thereon. Annex 1 and accessories 2 is an analog image having an image sensing device similar to that shown in the figure, wherein the image sensing device uses a color filter layer having a Bayer pattern as shown in Fig. 3.

It has an early axis asymmetry.

In an embodiment, the color filter and the optical layer comprise: a two-dimensional array pattern, including a plurality of first color tints, a plurality of color filters, a light object, and a plurality of third color filters, wherein The first color filters, the second color filters, and the third color systems are periodically arranged, and at least the first colors in the second region of the two-dimensional array pattern The filter, the second color filter and the third color filter and the second color region of the two-dimensional array pattern, the second color phosphors, and the second color phosphors These second color filters are mirror image symmetrical. The above and other objects, features, and advantages of the present invention will be described in the following description. -0〇2/ShawnChang, 〇200905870 [Embodiment] FIG. 5 and FIG. 6 are schematic diagrams showing an image sensing apparatus 100' according to an embodiment of the present invention, wherein FIG. 5 illustrates a pixel group. A top view, and FIG. 6 is a cross-sectional view showing a pixel profile of the first row D, the fourth/five row E, and the eighth row F in the pixel group in FIG. 5. As shown in FIGS. 5 and 6, the image sensing device includes a plurality of pixels 30 each having a semiconductor substrate (one of the surface layers of the substrate) (photosensitive diode/photoelectricity) The image sensing device 1A further includes a light shielding layer 32 having a light shielding region to shield a portion of the pixel 30 without shielding the photosensitive second body/light pen conversion element 35 from the light-reducing layer 32. An opening region 33 is formed such that the light 500 can penetrate and be incident on the photodiode/photoelectric conversion element%. In addition, the image sensing device 100 also includes a microlens 34 for collecting the light 500 to the photodiode/photoelectric The conversion element 35. Furthermore, the image sensing device 100 also includes colors of different color filters such as red (R), green (G), and blue, or other color filters. Shuguanglu 36. For the purpose of explanation, in Figure 5, the interior of the car = 36, the actual image sensing device 100 may use hundreds of X arrays of pixel arrays arranged in a two-dimensional mode. Figure 5 and Figure 6, set in the adjacent area of the pixel 3 The pixel 3Q placed in the center of the pixel group has the light receiving region of the photosensitive diode/photoelectric conversion element 5 (the center of gravity of the lighi recepti〇n is smaller than the center of gravity of the inner opening region 33 and the microlens%) 〇978-A32882TWF/VIP2007-002/ShawnChang] 1 200905870 is closer to the setting of the surrounding area. Therefore, the optical axis 600 of the light 500 can be received by the microlens 34 and received by the photosensitive diode/photoelectric conversion element 35. The center of gravity of the light reception region coincides with the conventional image sensing device shown in Fig. 1, and the image sensing device in the fifth and fourth images. In the pixel 30 in the first row D of 100, the center of gravity of the microlens 34 and the opening region 33 is set in the center of gravity of the light receiving region of the photosensitive diode/photoelectric conversion element 35 as described in FIG. On the right side, and in the pixel 3 0 of the fourth/fiveth row E, the center of gravity of the light receiving region of the photosensitive diode/photoelectric conversion element 35 as described in FIG. 5, the center of gravity of the microlens 34 and the opening region 33 are set. At its center. And in the eighth line F in the prime 30, as opposed to The center of gravity of the light receiving region of the photodiode/photoelectric conversion element 35, the center of gravity of the microlens 34 and the open region 33 is disposed on the left side thereof. As described above, since the pixels 30 disposed adjacent to the peripheral region are disposed on the pixel group The pixel 30 of the central portion of the group has a center of gravity of the nght reception region of the photodiode/photoelectric conversion element 35, and is closer to the peripheral region than the center of gravity of the inner opening region 33 and the microlens 34. situation. Therefore, when the light 500 penetrates the microlens 34 and is incident on the photosensitive diode/photoelectric conversion element 35, it is not intercepted by the light shielding area of the light shielding layer 32. Thus, the difference between the maximum value and the minimum value of the output signals of the pixels located at different positions of the image sensing device shown in FIGS. 5 and 6 can be reduced to less than 10% of the average value of the output signal. The degree of dispersion is still inevitable. 0978-A32882TWF/VIP2007-002/ShawnChang 12 200905870 This is the color filter used for the color filter and optical layer 36 of the image sensing device 100 as shown in Figures 5 and 6®.
