Description

1342617 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種固態影像感測器,且更特定而言本發 明係關於一種包括用光吸收彩色濾光片覆蓋之小像素的互 補金氧半導體(CMOS)影像感測器。 【先前技術】 現代CMOS影像感測器之典型象素包括—光電二極體(更 特定而言,一插接(pinned)光電二極體)及四個電晶體。光 電二極體收集光生電荷,該光生電荷稍後由一電荷轉移電 晶體在適當瞬間轉移至一浮動擴散(FD)節點上。該FD節點 充當電荷偵測節點。在電荷轉移之前,FD節點需要重置至 一適當參考電壓。該重置引起可能通常被添加至一出現在 FD節點上之信號的kTC雜訊。因此,有必要讀取節點上 之電壓兩次,第一次在電荷轉移之前,及第二次在電荷轉 移之後。此操作被稱為CDS(相關二重取樣p CDS操作允 許感測僅由自光電二極體轉移之電荷所引起之節點上的電 壓基。 源極隨耦器(SF)電晶體經由一連接至FD節點之SF電晶體 之閘極、一連接至一電源電壓(Vdd)端子之汲極及一經 由定址電晶體連接至一共用行感測線之源極來感測fd節點 上之電壓。為此,通常有必要在一標準CM〇S影像感測器 之每一像素中倂入4個電晶體。頒予Paui p Lee等人之發明 稱為 Active Pixel Sensor Integrated with Pinned Photodiode"之美國專利申請案第5,625,21〇號描述一種真有 119685.doc 1342617 一插接光電二極體的例示性4T像素電路。
•I 在現代CMOS感測器設計中’用於若干光電二極體之電 路可共用’如可在頒予R· M. Guidash等人之發明名稱為 "Active Pixel Sensor with Wired Floating Diffusions and Shared Amplifier”的美國專利申請案第6,657,665 Bi號中例 示性地找到。在此專利申請案中,雙像素包括位於一感測 器影像陣列之相鄰列中且共用相同電路之兩個光電二極 體。 大多數現代CMOS影像感測器中之色彩感測藉由將適當 彩色濾光片置放於光電二極體上來完成,如圖1中所展 示°藍色濾光片1 0 1吸收綠光及紅光且僅讓藍光光子進入 下方光電二極體區域。類似地’綠色濾光片1 〇2吸收藍光 及紅光且僅讓綠光光子進入下方矽塊體。元件符號1〇3表 示紅色濾光片。藍光及綠光光子具有高能量,且因此通 常在一自矽塊體之表面至其一確定區域104所界定之深度 Xg範圍内非常快速地被吸收。另一方面,紅光光子具有低 月&董且穿透比以上區域104更深之區域。更特定而言,在 產生任何光電子之前,紅光光子可穿透至一在一位於深度 Xepi之磊晶基板區域與一重度摻雜之p+型基板1〇6之間的 介面105。參考字母”Xr"表示介面1〇5離矽塊體(亦即,重 度摻雜之P+型基板106)之表面的深度。 备在重度摻雜之P+型基板1〇6中產生電子丨時,電子 1〇7非常快速地與位於重度摻雜之?+型基板1〇6中之電洞再 結合且不能夠被收集在,,紅色”光電二極體中。另一方面, II 9685.doc 非耗盡磊晶層109中所產生之電子108具有比電子107更長 的壽命,且在非耗盡蟲晶層109中側向及垂直地自由擴散 直至電子H)8抵達耗盡區域11〇之邊界為止。耗盡區域ιι〇 之邊界位於離矽塊體之表面的深度Xdl處。 备電子111進入耗盡區域110時,電子ln快速地被掃掠 至位於形成有N型摻雜層112之區域中的各別光電二極體勢 井中。光電二極體由N型摻雜層112及p+型插接層η]緊接 矽塊體之表面來形成。此結構被稱為插接光電二極體。p+ 型插接層113各自沿各別淺溝槽隔離(STI)區域丨14之側邊及 底部延伸、各自藉由蝕刻矽塊體而形成,以將感光單元與 對應電路彼此分離及絕緣。用二氧化矽填充STI區域〗】4。 一氧化石夕亦覆蓋光電二極體表面區域且在轉移閘極117下 方延伸。元件符號115及116分別表示填充STI區域n4之二 氧化石夕及在轉移閘極117下方延伸且同時覆蓋光電二極體 表面區域之二氧化矽。轉移閘極丨丨7由多晶矽形成。 當將適當偏壓經由對應連接丨丨8(僅示意性地展示)施加至 轉移閘極117中的每一者時,儲存在光電二極體勢井中之 電子電荷被轉移至藉由摻雜N+型摻雜劑所形成之各別FD 節點119上。FD節點119通常經受—電壓變化。此電壓變化 隨後被適當放大器(SF)感測到,該等適當放大器(SF)由各 別導線120(亦僅示意性地展示)個別連接至FD節點119。電 壓變化表示一所要信號。光電二極體及轉移閘極11 7通常 由另一層121覆蓋,其中另一層121由二氧化矽或多層二氧 化矽形成,且在彩色濾光片之前之其他透明薄膜沈積於頂 119685.doc 1342617 部。隨後可將顯微透鏡(未圖示)沈積於藍色濾光片1〇1、綠 色濾光片102及紅色濾光片103之頂部以將光聚焦於光電二 極體之表面區域上。 如可自圖1容易理解,由非耗盡磊晶層109中之紅光所產 生之電子亦可側向地擴散且進入相鄰光電二極體之耗盡區 域110。此現象通常引起非吾人所樂見之色彩串擾,因為 紅色光生電子通常終止於錯誤之"綠色,,或"藍色"光電二極 體之光電二極體勢井中。此色彩串擾可在像素之側向尺寸 小於2哗且垂直尺寸保持在約5 μιη之小尺寸像素中為顯著 的。色彩串擾可藉由減少磊晶層之厚度(亦即,介面ι〇5之 深度Xr)且從而減小非耗盡磊晶層1〇9之厚度或將位於深度 Xdl的耗盡區域110之邊界延伸至深度χ{}2來減小。 然而,以上所描述之兩種方法可能具有一些限制。淺磊 晶厚度引起過多红光電子產生於重度摻雜之? +型基板1〇6 中且因此與重度摻雜之P+型基板1〇6令之電洞再結合。結 果,紅光電子可對信號不起作用。通常需要使蟲晶厚度約 5.〇 μιη或更大以具有一良好"紅”光響應。 一直延伸至介面1G5之厚耗盡亦可引起限制。完成厚耗 盡所必要之蟲晶層的輕度摻雜可增加暗電流產纟,且可導 致位於接近表面之P+型插接層113與重度摻雜之p+型基板 1〇6之不連續性及分離,如由針對此位準之蟲晶摻雜之分 離的耗盡層邊界122所指示。當觀_不連續且分離之P + 型插接層⑴時’有必要由—些其他構件(例如,置放於像 素頂部之金屬導線)提供其他電連接至p+型插接層⑴。此 119685.doc
