Description

光感測器及其製造方法
本發明涉及一種半導體裝置及其製作方法,尤其有關於光感測半導體元件及其製造方法。
在光感測元件領域中,光電晶體可以設計成二端式或者三端式元件。當元件設計成三端式元件時,雖然可以獲得較高之光電流增益,但三端式元件也具有較大的穩態電流,容易造成元件漏電流增加與靜態功率損害的問題。此外,若想從三端式光電晶體的總電流中萃取所需的光電流亦需要額外的技術設計,因此造成諸多不便。然而,對於一個兩端式光電晶體而言,由於其基極通常處於浮接的狀態,雖然可以有效的降低元件漏電流,但同時也降低了光電流增益。綜合上述,目前光電晶體仍面臨許多亟需改善的問題。

本發明之構思可以利用不同形式之實施例表示,說明書所示附圖與文中說明係為本發明之一實施範例,並非意圖將本發明限制於所示附圖及/或所描述之特定實施例中。
本發明第一實施例之光感測元件結構1可參閱圖1,圖1係該光感測元件結構1元件之上視圖,該元件長度和寬度皆為60微米。其中,該光感測元件結構1係藉由堆疊不同的結構層,在該光感測元件結構1上形成一個或複數個標準矽鍺異質接面雙極性光電晶體,該光電晶體結構層可區分為一基板區域3(簡稱基板)、一集極區域 20(簡稱集極),一基極區域 25(簡稱基極),以及覆蓋部分基極區域25之射極區域12(簡稱射極)。
圖2係本發明第一實施例的光感測元件結構1沿著圖一A-A’切線的剖面圖,圖2的編號若與圖1相近,代表相類似的組成元素。圖2所示的基板3係P型傳導半導體,該基板3內包含一N型傳導半導體內埋層22;設置於鄰近該N型傳導半導體內埋層22的區域為一N型傳導半導體的磊晶層24,該N型傳導內埋層22通常具有1019/cm3-1021/cm3左右的離子摻雜濃度,其離子摻雜濃度一般高於於該N型傳導磊晶層24;設置於鄰近該N型傳導磊晶層的區域為一N型傳導的集極區域20,該N型傳導集極區域20通常亦具有比該N型傳導磊晶層24較高的離子摻雜濃度;設置於鄰近該N型傳導磊晶層24的區域為一P型傳導半導體層,為該光電晶體之基極區域25。
請參閱圖2,該光感測元件結構具有一離子重摻雜區域15,設置於該電晶體的基板區域3上,藉以降低端點電阻值,並且設置複數個場氧化層(FOX)14於該離子重摻雜區域15和集極區域20之間,藉此形成電性絕緣。該射極區域12由N型傳導的多晶矽材料所組成,相較於該N型傳導磊晶層具有較高的離子摻雜濃度,該N型傳導射極區域12同時覆蓋部分P型傳導基極區域25。另外,該光感測元件結構上設置複數個金屬接觸端10於該重摻雜區域15、集極區域20、基極區域25以及射極區域12之上,藉此形成元件金屬接觸,以降低傳導電阻。其中,該離子重摻雜區域15的金屬接觸端10藉由一金屬導線5所形成的電性傳導區域電性連結至該基極區域25。
圖3A和B係本發明第一實施例光敏元件的電路結構圖,如圖3A和B所示,該光敏元件具有基極50、集極55、射極60以及P型基板56等組成單元。圖3A表現本發明一實施例的一個構向,該基極50利用一金屬導線70形成電性傳導區電性連結至該P型基板56;圖3B表現另一種構向,該基極50利用一離子重摻雜區域80形成一電性傳導區電性連結該P型基板56。
圖4係本發明第一實施例光感測元件結構1的光電流對光照射強度的對應圖,當該光感測元件結構1在施加一較小的偏壓(VCE=1.2V)情況下,傳統結構的光感測元件結構,具有長寬皆為60微米的元件尺寸,其基板與基極並未形成任何電性傳導區域,該結構已具有可觀察的集極輸出電流,當輸入光照射功率在一個寬廣的動態範圍下(涵蓋120dB),該光電流對光照射強度的關係呈現相當線性的行為。請參閱圖4,當光照射強度低至0.01流明,其光輸出電流仍有1.7奈安培,相當於電流密度為每平方公分47.2微安培,相同元件與光照射強度下,偵測到的暗電流僅為1.7微微安培,該傳統光感測元件結構的訊號對雜訊比在0.01流明的光照射強度下可保持為60dB。
另外,本發明第一實施例中矽鍺異質接面光電晶體,其特徵在於具有一電性傳導區域電性連結該光電晶體之基極與該基板。圖4為此光感測元件結構對於多種入射光線強度所偵測到的光感應電流,相較於傳統元件的光感測元件結構,其光電晶體之基極與基板並未具有一電性傳導區域形成一電性連結,具有一百倍以上的光電流增強效果,在入射光強度為0.01流明的環境下,偵測到的光感應電流可達到0.2微安培,驗證本發明之光感測元件結構的基極若與基板若形成一電性傳導區域,提供兩者形成一電性連結,可以有效的增加該元件的光感應能力。另外,在相同入射光強度為0.01流明的環境下,在相同的外在施加偏壓下(VCE=1.2V),該元件的暗電流僅為18微微安培,等同於每平方公分0.5微安培的電流密度。當一矽鍺異質接面光電晶體具有一基極與基板電性傳導區域形成電性連結的結構,相較於傳統結構光感測元件結構的訊號對雜訊比,在0.01流明的光照射下,可以有效的從60dB提昇至80dB。
請參照第5圖,本發明第一實施例中,光感測元件結構上的矽鍺異質接面光電晶體(HPT)處於不同入射光波長的情況下,所產生的光響應度散布圖。圖5上有三條曲線分別代表具有傳統結構的矽鍺異質接面光電晶體元件的集極電流(HPT_IC)和射極(HPT_IE)電流,詳細電流值請參照圖5中右側刻度,以及具有基極與基板電性傳導區域形成電性連結的矽鍺異質接面光電晶體元件的光電流(HPT_I),詳細電流值請參照圖5中左側刻度。該傳統結構的矽鍺異質接面光電晶體,其光電晶體的基極與基板並未形成一電行傳導區域造成電性連結,當元件施加偏壓VCE為1.2 V,入射波光長為630奈米的情況下,該元件的集極電流具有一峰值,該峰值在630奈米入射光下,每瓦的入射功率可以產生3.7安培的光電流。由於一般光感測元件結構都具有一N型傳導的內埋層,該N型傳導內埋層與P型傳導的基板形成一額外的寄生PN接面,可以用於接收入射光,以產生額外的集極電流,該額外的集極電流雖然不能藉由二端式異質接面光電晶體產生電流放大的效果,但會隨著入射光的波長增加而增加,其原因在於此寄生PN接面的空乏區相當寬廣以及基板厚度相當的厚,因此在長波長的入射光照射下,元件所產生的集極電流的值通常會大於射極電流值。
請參照圖5,本發明一具體實施例中矽鍺異質接面光電晶體,處於不同入射光波長的情況下,對應產生的光響應度散布圖。其中,當傳統結構矽鍺異質接面光電晶體,處於較短波長的入射波長光照射環境下,元件的射極與集極的光響應度曲線大致上重疊,且集極電流略大於射極電流,但隨著入射光波長增加,集極與射極的光響應度曲線逐漸的分開不重疊,但仍保持集極電流大於射極電流的關係。由於光感應器元件結構的基板在長波長的入射光照射情況下,相較於短波長入射光照射可以產生較多的電洞,且在一矽鍺異質接面光電晶體元件其基極與基板形成一電性傳導區域的元件中,基板照射長波長光後所產生的電洞可以被導引到基極端形成光電流輸出,因此該元件光響應度的峰值會落在較長波長的入射光位置,同時光響應度的峰值會相較於傳統結構的元件高。請參照圖5,在每瓦入射光能量照射下,一矽鍺異質接面光電晶體具有其基極與基板形成一電性傳導區域產生電性連接的結構,其元件光響應峰值可以高達75安培。
請參照圖6係本發明一具體實施例中矽鍺異質接面光電晶體的光響應度散布圖。該矽鍺異質接面光電晶體元件(HPT)具有其基極與基板形成一電性傳導區域產生電性連結的結構,該元件的集極電流(Ic)和基板電流(Isub)與總集極電流(Ic+Isub)分別標示於圖6的不同曲線中。請參照圖6,該矽鍺異質接面光電晶體的基板電流Isub(電洞為主),相較於該元件集極電流Ic的峰值,位處在較長波長的位置。上述結果與具有基板與基極電性連結的矽鍺異質接面光電晶體所量測到的光響應度結果一致,代表基板藉由長波長入射光照射下所產生的載子可以提供基板一額外的光電流產生,進而增加元件輸出電流。
圖7係本發明另一實施例的光感測器元件結構的剖面圖,該光感測元件結構包含一個以上具有互補式金屬氧化物半導體(CMOS)結構的光電晶體2,該CMOS光電晶體 2可與一般業界標準半導體製程相容,該CMOS光電晶體2具有一橫向NPN雙極性接面電晶體的結構,包含一N型傳導射極區域122、一P型傳導基極區域250和一N型傳導集極區域200。該CMOS光電晶體2設置於一P型傳導半導體井22上,該P型傳導半導體井222與一P型傳導基板30,藉由一設置於兩者間的N型傳導半導體層220形成電性隔絕。其中,本發明特徵在於將該P型傳導基極區域250與該P型傳導基板30藉由一電性傳導區85產生一電性連結關係。
圖8A-8B係一光敏元件電路圖,該光敏元件具有一個以上的CMOS光電晶體2,該CMOS光電晶體2的電路結構具有一集極端點95、一射極端點90、一基極端點85,一基板端點96,當傳統CMOS光電晶體操作於一般狀態下,該基極端點96設計為一浮接狀態,光電流訊號僅由集極端點95與射極端點90輸出。請參閱圖8A係本發明之一面向,由於該基板端點96與該基極端點85在一般操作狀態下,並未存有任何電性連結的關係。藉由設置一金屬導線92於該光電晶體之基板端點96與基極端點85之間,形成一電性傳導區域進而產生一電性連結關係,該金屬導線92材料可為鋁、銅、金、銀、石墨烯、氧化銦錫(ITO)或相類似之電性良導體。參閱圖8B係本發明之另一面向,該光電晶體之該基板端點96與基極端點85之間可透過一離子重摻雜方式,形成一電性傳導區域80,進而產生一電性連結該基板端點96與該基極端點85。
圖9係本發明另一實施例光感測元件結構4的上視圖,該光感測元件結構4包含一個以上的光電晶體,該光電晶體具有一基板(圖中未標示)、一集極區域110與一集極區域接觸點115、一射極區域101與一射極區域接處點105以及一基極區域118。該基極區域118兩側利用離子重摻雜的方式往外延伸,越過該集極區域110藉由一電性傳導區域直接與基板相互連結,形成一電性連結路徑。利用上述離子重摻雜的方式,延伸該基極區域118直接與基板形成電性接觸,而不需要透過任何金屬導線或接觸孔的方式,可以有效的減少線電阻以及接觸電阻。
參閱圖10係本發明另一實施例光感測元件結構6的上視圖,圖11係本發明另一實施例光感測元件結構6於圖10中沿著B-B’切線的剖面圖。此實施例相似於圖7所示的結構,不同之處在於此光感測元件結構利用一N型傳導金屬氧化物半導體(金氧半)場效電晶體130取代圖7原先標示之場氧化層(FOX),該金氧半場效電晶體130設置於一集極區域127與一射極區域125之間,使得該集極區域127與該射極區域125兩者形成一電性隔離。該N型傳導金氧半導體場效電晶體130的汲極區域與源極區域可以視為該光感測元件結構上一光電晶體的集極區域127與射極區域125,同時該N型傳導金氧半場效電晶體130的通道寬度可以利用標準半導體製程中的最小通道長度規則進行製造,以減少該光電晶體的集極區域127與射極區域125之間的距離。請參閱圖10,該光電晶體的基板區域30藉由一金屬導線50產生一電性傳導區域產生電性連結至該電晶體的基極區域250。請參閱圖11,該光電晶體操作在兩端式光電晶體情況下,該N型傳導金氧半場效電晶體130的閘極126原始情況是處於浮接的狀態。另外該光電晶體的基極區域250與射極區域125藉由場氧化層(FOX)形成電性隔絕。
