Priority of the case, which is hereby incorporated by reference in its entirety in its entirety, the entire disclosure of the entire disclosure of the entire disclosure of the entire disclosure of the entire disclosure of The contents of each patent application are incorporated herein by reference.

發明領域Field of invention

本發明一般係有關於用以在切割之前將玻璃黏著到一晶圓基板的晶圓級封裝(WLP)方法,且更特別係在於一種封裝一互補金屬氧化物半導體(CMOS)或電荷耦合裝置(CCD)類型影像感測器之低成本方法,藉以使該感測器免於微粒污染以及組裝期間的應力損壞。The present invention generally relates to a wafer level package (WLP) method for bonding glass to a wafer substrate prior to dicing, and more particularly to packaging a complementary metal oxide semiconductor (CMOS) or charge coupled device ( A low cost method of CCD) type image sensor to protect the sensor from particulate contamination and stress damage during assembly.

發明背景Background of the invention

在微電子光學模組之組裝期間產生微鏡頭或影像感測器的微粒污染可能使該模組故障。微粒對於相機模組組裝程序期間的產量損失重要性多達百分之90。裝置解析度越高,由於微粒造成的產量損失隨著像素尺寸越小而增加。例如,在一3百萬畫素感測器中,其像素尺寸係小於2微米。如果一微粒能夠阻擋超過一個像素而不會使影像品質降低,則在此應用例中之容許微粒尺寸係限制在直徑2微米。為了限制此尺寸之微粒數量,在相機模組組裝程序期間需 要嚴格的微粒控制量測,以避免產量損失。這些微粒污染量測會增加組裝操作的成本。Particle contamination of the microlens or image sensor during assembly of the microelectronic optical module may cause the module to malfunction. The particles are as important as 90 percent of the yield loss during the camera module assembly process. The higher the resolution of the device, the more the yield loss due to the particles increases as the pixel size is smaller. For example, in a 3 million pixel sensor, the pixel size is less than 2 microns. If a particle can block more than one pixel without degrading image quality, the allowable particle size in this application is limited to 2 microns in diameter. In order to limit the number of particles of this size, it is required during the camera module assembly process. Strict particle control measurements are required to avoid yield loss. These particulate contamination measurements increase the cost of assembly operations.

WLP方法有助於解決現有晶片直接封裝(COB)技術法的污染問題。此生產改良係藉著在晶圓切割以及安置裝置之前使用一玻璃層,保護感測器之主動區域免於遭受污染所達成。由於落在玻璃/鏡片之頂表面上的微粒會與感測器隔開玻璃層之厚度(典型為0.3到0.4毫米),故最大的容許微粒尺寸能夠達到直徑25微米,而不會降低影像品質。此外,任何由於玻璃表面之微粒污染而無法運作之單元能夠輕易地藉著重做而恢復。從而能夠使用一晶圓級封裝方法顯著地提升相機模組組裝程序之產量。The WLP method helps solve the contamination problem of the existing wafer direct packaging (COB) technology. This production improvement is achieved by protecting the active area of the sensor from contamination by using a glass layer prior to wafer cutting and placement. Since the particles falling on the top surface of the glass/lens are separated from the sensor by the thickness of the glass layer (typically 0.3 to 0.4 mm), the maximum allowable particle size can reach 25 microns in diameter without degrading image quality. . In addition, any unit that is inoperable due to particulate contamination of the glass surface can easily be recovered by focusing on it. This enables a wafer-level packaging approach to significantly increase the throughput of the camera module assembly process.

目前所使用的一種WLP方法(例如,Tessera公司之Shellcase CF)將一晶圓尺寸玻璃板結合在晶圓之感測器側位置的腔室壁之頂部,從而在各個感測器上方產生一光學腔室。此步驟之後接著進行玻璃切割與晶背研磨。最後,將晶圓切割成為個別的裝置。儘管此方法顯示出在產量方面優於COB方法,其可能在矽氧烷之周圍內側上產生高應力,如此可能會發生產量損失。One of the currently used WLP methods (eg, Tressera's Shellcase CF) combines a wafer-sized glass plate on top of the chamber wall at the sensor side of the wafer to create an optical image above each sensor. Chamber. This step is followed by glass cutting and crystal back grinding. Finally, the wafer is cut into individual devices. Although this method shows superior to the COB method in terms of yield, it may generate high stress on the inner side of the siloxane, so that yield loss may occur.

其他WLP方法(例如,Schott公司之OPTO-WLP)同樣顯示出在生產管理方面的優點。此方法之第一步驟係為藉著一玻璃蓋保護敏感的主動元件構造。一特定之黏著晶圓結合方法使得結合層中能夠進行選擇性的黏著劑覆蓋。在接下來的步驟中,經過結合之矽氧烷-玻璃夾心構造係由矽氧烷側(背側)使其變薄。後續步驟有關於將通孔蝕刻進入矽氧 烷側,以便使結合襯墊連通到晶圓背部,重新分配連接到晶圓背側以及球形附裝之接點。該方法因而需要形成通孔/通道,多重層之導線/絕緣材料以及許多方法步驟非常倚重手動的反覆試驗方法。結果,使用此方法時,前導作業時間非常長,且可能會產生方法不穩定性。Other WLP methods (eg, SCHOTT OPTO-WLP) also show advantages in production management. The first step in this method is to protect the sensitive active component construction by means of a glass cover. A specific adhesive wafer bonding method enables selective adhesive coverage in the bonding layer. In the next step, the combined decane-glass sandwich structure is thinned by the oxane side (back side). The next step is about etching the via into the helium The alkane side is such that the bond pads communicate to the back of the wafer, redistributing the connections to the back side of the wafer and the ball-attached contacts. The method thus requires the formation of vias/channels, multiple layers of wires/insulation materials, and many method steps that rely heavily on manual repetitive testing methods. As a result, when using this method, the lead time is very long and method instability may occur.

發展本發明係用以消除本段發明背景所述的問題。The present invention has been developed to eliminate the problems described in the background of the invention.

發明者理解到的是,諸如Shellcase CF封裝之WLP方法,其中玻璃係在將其附裝到裝置晶圓之後加以切割有可能產生裝置損壞。此損壞可能由於在晶圓背研磨或是在玻璃附裝到裝置晶圓以後進行切割期間所衍生的機械應力所引起。此外,影像感測器可能由於切割玻璃方法期間所累 積引發的靜電放電而產生損壞。另一種可能產生故障的方法係有關於電子襯墊由於玻璃晶圓切割步驟期間所產生之玻璃碎屑的污染。本發明提出的方法旨在解決這些與其他缺點。The inventors have appreciated that a WLP method such as the Shellcase CF package in which the glass is cut after it is attached to the device wafer may result in device damage. This damage may be caused by mechanical stresses that are generated during wafer back grinding or cutting after the glass is attached to the device wafer. In addition, image sensors may be tired during the method of cutting glass The electrostatic discharge caused by the accumulation causes damage. Another method that can cause failure is the contamination of the electronic pad due to the glass debris generated during the glass wafer cutting step. The method proposed by the present invention aims to address these and other disadvantages.

本發明提出之用於一微電子影像感測器裝置的WLP方法包括之步驟為在裝置封裝方法開始時,將一薄的經切割玻璃板附裝於晶圓基板上。該玻璃蓋體在晶圓製造的晶粒切割步驟期間對該裝置提供支撐。此外,該玻璃蓋體能夠防止來自於周遭環境之微粒嵌入微鏡片或是影像裝置。The WLP method for a microelectronic image sensor device proposed by the present invention includes the step of attaching a thin cut glass plate to a wafer substrate at the beginning of the device packaging process. The glass cover provides support to the device during the die cutting step of wafer fabrication. In addition, the glass cover prevents particles from the surrounding environment from being embedded in the microlens or imaging device.

玻璃附裝方法之一種實施例係有關於在一晶圓上製造影像感測器(以及微鏡片)之應用。一玻璃晶圓(例如,厚度400微米)首先係暫時地安置到一組裝在一玻璃晶圓運送器14上之玻璃晶圓夾具12(其可為透明),如第1A圖中所示。該暫時性安置能夠透過使用一切割帶之矩陣16(其能夠使用超紫外光(UV)加以固化)加以達成,如第1B圖中所示。該暫時性安置亦能夠使用其他黏著材料加以達成。切割帶之圖案符合影像感測器晶圓的圖案,透過該圖案能夠將其製造成使其具有較影像感測器晶圓更寬的通道。換言之,各個黏著晶粒具有對應於影像感測器晶粒縮小的覆蓋區。One embodiment of a glass attachment method relates to the application of image sensors (and microlenses) on a wafer. A glass wafer (e.g., 400 microns thick) is first temporarily placed into a glass wafer holder 12 (which may be transparent) assembled on a glass wafer carrier 14, as shown in Figure 1A. This temporary placement can be achieved by using a matrix 16 of dicing tapes that can be cured using ultra-ultraviolet light (UV), as shown in Figure 1B. This temporary placement can also be achieved using other adhesive materials. The pattern of the dicing tape conforms to the pattern of the image sensor wafer through which it can be fabricated to have a wider channel than the image sensor wafer. In other words, each of the adhesive dies has a footprint corresponding to the reduction of the image sensor dies.

玻璃晶圓10接著係加以切割(以符合位於影像感測器上的晶粒圖案),如第2A與2C圖中所示。此處,該玻璃圖案能夠加以製造成使其具有較影像感測器晶圓更窄的通道。換言之,各個玻璃晶粒具有由一影像感測器晶粒放大的覆蓋區,以致於使其超過影像感測器之尺寸,但卻不會覆蓋 用於影像感測器裝置之電子接點襯墊。此外,蓋體之邊緣20能夠稍微向內推拔,如第2B圖中所示,以便使結合到影像感測器之表面較相反表面為大。The glass wafer 10 is then cut (to conform to the grain pattern on the image sensor) as shown in Figures 2A and 2C. Here, the glass pattern can be fabricated to have a narrower channel than the image sensor wafer. In other words, each of the glass dies has a footprint that is magnified by an image sensor die such that it exceeds the size of the image sensor but does not cover Electronic contact pad for image sensor devices. In addition, the edge 20 of the cover can be pushed slightly inward, as shown in Figure 2B, so that the surface bonded to the image sensor is larger than the opposite surface.

在經切割玻璃進行清潔以後,該玻璃晶圓運送器以及固持該經切割玻璃之玻璃晶圓夾具(一併顯示為22)係加以翻轉與對齊,以便使經切割玻璃之暴露表面面對影像感測器晶圓24,並鏡射位於晶圓上的影像感測器裝置之圖案,如第3A與3B圖中所示。產生稍微放大尺寸之蓋體使得此對齊步驟對於佈置或對齊誤差影響不會太過敏感。光學黏著劑26係選擇性地施加到影像感測器晶圓24,以致於使其塗佈各個光學影像感測器以及其對應微鏡片(若可行的話),留下周圍未塗佈之電子接點,如第3A圖中所示。該方法之一樣態包括控制黏著劑之分配方式(圖案與數量)以及選擇黏著劑,以便使能夠降低影像品質之諸如留存在影像感測器內微氣泡的缺陷降到最低。此外,由於黏著劑終究會與外部環境接觸,故黏著劑亦必須能夠耐熱與耐水。After being cleaned by the cut glass, the glass wafer carrier and the glass wafer holder holding the cut glass (shown as 22 together) are flipped and aligned so that the exposed surface of the cut glass faces the image. The wafer 24 is mirrored and mirrored by a pattern of image sensor devices on the wafer, as shown in Figures 3A and 3B. Producing a slightly enlarged cover allows this alignment step to be less sensitive to placement or alignment errors. The optical adhesive 26 is selectively applied to the image sensor wafer 24 such that it coats the individual optical image sensors and their corresponding microlenses (if applicable), leaving the surrounding uncoated electronic contacts Point, as shown in Figure 3A. The state of the method includes controlling the manner in which the adhesive is dispensed (pattern and number) and selecting an adhesive to minimize defects such as microbubbles remaining in the image sensor that can degrade image quality. In addition, since the adhesive will eventually come into contact with the external environment, the adhesive must also be resistant to heat and water.

在另一實施例中,光學黏著劑26係施加到經切割玻璃而非影像感測器/鏡片組合件,且接著該玻璃晶粒係與影像感測器晶圓24相結合,如第3B圖中所示。能夠實施諸如旋轉噴塗之一方法將黏著劑26施加到經切割玻璃晶粒。由於光學黏著劑相當昂貴且此方法會耗費更多黏著劑,故能夠對於此方法進行改良,使其更符合經濟效益。In another embodiment, the optical adhesive 26 is applied to the cut glass rather than the image sensor/lens assembly, and then the glass die is combined with the image sensor wafer 24, as shown in FIG. 3B. Shown in . Adhesion agent 26 can be applied to the cut glass dies by one of methods such as spin coating. Since optical adhesives are relatively expensive and this method consumes more adhesive, this method can be modified to make it more economical.

經切割玻璃晶圓接著係結合到影像感測器晶圓(一併稱之為30),其中並無腔室,如第4圖中所示。某些黏著劑 施加尺寸與結合程序能夠包括固定玻璃與影像感測器表面的距離,以及在特定的平行限制下產生一玻璃/影像感測器夾心構造。該光學影像感測器晶圓夾心構造30係自玻璃晶圓夾具12鬆開,如第5圖中所示。黏著劑之固化以及從玻璃晶圓夾具12鬆開光學影像感測器晶圓夾心構造30能夠藉由明智地選擇UV波長或是特殊溫度與曝光時間,而在同一步驟中完成。The cut glass wafer is then bonded to an image sensor wafer (collectively referred to as 30) with no chambers as shown in FIG. Some adhesives The application size and bonding procedure can include the distance of the fixed glass from the image sensor surface and the creation of a glass/image sensor sandwich construction under specific parallel constraints. The optical image sensor wafer sandwich construction 30 is released from the glass wafer fixture 12 as shown in FIG. The curing of the adhesive and the release of the optical image sensor wafer sandwich construction 30 from the glass wafer holder 12 can be accomplished in the same step by judiciously selecting the UV wavelength or the particular temperature and exposure time.

光學影像感測器晶圓夾心構造30接著係使用做為支撐之用的玻璃晶粒加以切成晶粒,如第6A圖中所示。在一另擇實施例中,該切割能夠在自玻璃晶圓夾具鬆開該夾心構造之前完成。一代表性影像感測器32以及保護玻璃蓋體係顯示於第6B圖中。此晶圓級封裝方法相信係為對於現今業界所使用的晶圓級封裝方法之一較低成本的另擇方式。The optical image sensor wafer sandwich construction 30 is then cut into grains using glass dies for support, as shown in Figure 6A. In an alternative embodiment, the cutting can be completed prior to loosening the sandwich construction from the glass wafer fixture. A representative image sensor 32 and a protective glass cover system are shown in Figure 6B. This wafer level packaging approach is believed to be an alternative to the lower cost of one of the wafer level packaging methods used in the industry today.

另擇地,一覆蓋玻璃能夠經由腔室壁附裝到一影像感測器,以產生一內部腔室,如第7到13圖中所示。如第7圖中所示,一玻璃片50,其一側施加有UV切割帶52,在該玻璃片50之另一側上係附裝有多個腔室壁54。該等腔室壁能夠由LE型砧模切,一層環氧物56係施加到各個腔室壁54之頂表面。Alternatively, a cover glass can be attached to an image sensor via the chamber wall to create an internal chamber, as shown in Figures 7-13. As shown in Fig. 7, a glass sheet 50 is coated with a UV dicing tape 52 on one side and a plurality of chamber walls 54 attached to the other side of the glass sheet 50. The chamber walls can be cut by a LE-type anvil die, and an epoxy 56 is applied to the top surface of each chamber wall 54.

如第7A圖中所示,該等腔室壁54能夠藉著使用在切割進行之前附裝到玻璃板的黏著劑薄膜所形成。As shown in Figure 7A, the chamber walls 54 can be formed by using an adhesive film attached to the glass sheet prior to cutting.

接著,如第8圖中所示,該玻璃片50係以一切割鋸條58加以切割成為多個經切割玻璃晶粒60,其係藉由UV切割帶52固持在一起。同時,如第9圖中所示,一矽晶圓62(其上 形成有多個個別的影像感測器64)係以一研磨器66從其背側進行研磨,以便將該矽晶圓62背研磨到一所需厚度。由於此背研磨操作係實行於矽晶圓62,故其能夠在將腔室壁54施加到玻璃片50以及切割該玻璃片50的步驟之前、期間或之後加以實行。Next, as shown in FIG. 8, the glass sheet 50 is cut into a plurality of cut glass dies 60 by a dicing saw blade 58 which are held together by a UV dicing tape 52. At the same time, as shown in Figure 9, a wafer 62 (on which A plurality of individual image sensors 64) are formed by a grinder 66 from its back side to back grind the tantalum wafer 62 to a desired thickness. Since this back grinding operation is performed on the tantalum wafer 62, it can be carried out before, during or after the step of applying the chamber wall 54 to the glass sheet 50 and cutting the glass sheet 50.

此步驟之後,如第10A圖中所示,其上具有腔室壁54之經切割玻璃晶粒60能夠對齊位於矽晶圓62上的個別影像感測器64。該經切割玻璃晶粒60係藉由一玻璃晶圓夾具70固持成與矽晶圓62相對齊。該玻璃晶圓夾具70能夠在施加腔室壁54以及將其切割成為單獨的玻璃晶粒60之前、期間或之後暫時地附裝到玻璃片50。如第10B圖中所示,該玻璃晶圓夾具70以及矽晶圓62係彼此相對移動,以便使位於腔室壁54上之環氧物與矽晶圓62在圍繞個別影像感測器64處相接觸。此動作將腔室壁54結合到矽晶圓62。After this step, as shown in FIG. 10A, the cut glass dies 60 having the chamber walls 54 can align with the individual image sensors 64 on the ruthenium wafer 62. The cut glass die 60 is held in alignment with the tantalum wafer 62 by a glass wafer holder 70. The glass wafer holder 70 can be temporarily attached to the glass sheet 50 before, during, or after application of the chamber wall 54 and cutting it into individual glass dies 60. As shown in FIG. 10B, the glass wafer holder 70 and the tantalum wafer 62 are moved relative to one another such that the epoxy and tantalum wafer 62 on the chamber wall 54 are around the individual image sensor 64. Contact. This action bonds the chamber wall 54 to the tantalum wafer 62.

為了從總成鬆開玻璃晶圓夾具70,一UV光源(未顯示)提供UV光線,其使得玻璃晶圓夾具70鬆開該經切割玻璃晶粒60,如第11圖中所示。經切割玻璃晶粒60之外部表面如今能夠加以清潔(未顯示)。接著使用相同或不同的切割鋸條72,在腔室壁54之外側以及個別經切割玻璃晶粒60之間的位置切開該矽晶圓62,如第12圖中所示。以此方式將矽晶圓62分割成為個別的影像感測器封裝體74,其中一封裝體係顯示於第13圖中。To release the glass wafer holder 70 from the assembly, a UV light source (not shown) provides UV light that causes the glass wafer holder 70 to release the cut glass die 60, as shown in FIG. The outer surface of the cut glass die 60 can now be cleaned (not shown). The tantalum wafer 62 is then slit at the outer side of the chamber wall 54 and the individual cut glass dies 60 using the same or different dicing saw blades 72, as shown in FIG. In this manner, the germanium wafer 62 is divided into individual image sensor packages 74, one of which is shown in FIG.
