Description
本發明係關於光電二極體,特別是關於一種非擴散型光電二極體。
在光通訊中所使用的雪崩光電二極體(avalanche photodiode)除了設置光吸收層之外,還設置了倍增/窗層(multiplication/window layer)。相對於一般的光電二極體,雪崩光電二極體具有靈敏度高、速度快等優點。然而,雪崩光電二極體通常是通過擴散載子於一層狀結構中的方式來製作倍增/窗層,因此需要多道工藝。
於是,後續業者研發出非擴散型(non-diffusion type,或也可稱為as-grown type)光電二極體,其是直接形成倍增/窗層,而不是通過擴散的方式來製作。但是,這種非擴散型光電二極體卻產生了較大的暗電流(例如約6.51x10
-9A),其不利於將非擴散型光電二極體應用在各種產業上。
故,有必要提供一種非擴散型光電二極體,以解決習用技術所存在的問題。
本發明之一目的在於提供一種非擴散型光電二極體,其透過在中間層與倍增/窗層之間定義特定的邊界關係,以降低暗電流的產生。
為達上述之目的,本發明提供一種非擴散型光電二極體,包含:一基板、一緩衝層、一光吸收層、一中間層以及一倍增/窗層。該緩衝層設置在該基板上。該光吸收層,設置在該緩衝層上。該中間層設置在該光吸收層上且具有一第一邊界,其中該中間層係一I型半導體層或一漸變層。該倍增/窗層設置在該中間層上且具有一第二邊界,其中在俯視圖中,該第一邊界環繞該第二邊界,以及該第一邊界與該第二邊界之間的距離大於或等於1微米。
在本發明一實施例中,該第一邊界與該第二邊界之間的距離介於1微米至15微米之間。
在本發明一實施例中,該第一邊界與該第二邊界之間的距離介於2微米至15微米之間。
在本發明一實施例中,該緩衝層係一N型緩衝層、該光吸收層係一I型光吸收層以及該倍增/窗層係一P型倍增/窗層。
在本發明一實施例中,該N型緩衝層的材質包含N型的InP。
在本發明一實施例中,該I型光吸收層的材質包含I型的InGaAs。
在本發明一實施例中,該P型倍增/窗層的材質包含P型的InAlAs。
在本發明一實施例中,該中間層係該I型半導體層,以及該I型半導體層的材質包含I型的InP。
在本發明一實施例中,該非擴散型光電二極體更包含一接觸層,該接觸層設置在該倍增/窗層上。
在本發明一實施例中,該接觸層係一P型接觸層,以及該P型接觸層的材質包含P型的InGaAs。
為了讓本發明之上述及其他目的、特徵、優點能更明顯易懂,下文將特舉本發明較佳實施例,並配合所附圖式,作詳細說明如下。再者,本發明所提到的方向用語,例如上、下、頂、底、前、後、左、右、內、外、側面、周圍、中央、水平、橫向、垂直、縱向、軸向、徑向、最上層或最下層等,僅是參考附加圖式的方向。因此,使用的方向用語是用以說明及理解本發明,而非用以限制本發明。
請參照第1A及1B圖,第1A圖是本發明實施例之非擴散型光電二極體的剖面示意圖。第1B圖是本發明實施例之非擴散型光電二極體的中間層以及倍增/窗層的俯視示意圖,其中第1B圖係以俯視方式來繪示中間層以及倍增/窗層之間的關係圖,其他結構未繪示。本發明實施例之非擴散型光電二極體10包含:一基板11、一緩衝層12、一光吸收層13、一中間層14以及一倍增/窗層15。該基板11例如可以是N型基板。要提到的是,該基板11的材質可以參考用於現有光電二極體的已知基板的材質。該基板11主要用於承載非擴散型光電二極體10的各個層狀結構或器件,例如緩衝層12、光吸收層13、中間層14以及倍增/窗層15等。
本發明實施例之非擴散型光電二極體10的緩衝層12設置在該基板11上。在一實施例中,該緩衝層12例如是一N型緩衝層,該N型緩衝層的材質例如包含N型的InP(例如是N
+型的InP)。要提到的是,該緩衝層12的材質可以參考用於現有光電二極體的已知緩衝層的材質。
本發明實施例之非擴散型光電二極體10的光吸收層13設置在該緩衝層12上。在一實施例中,該光吸收層13例如係一I型光吸收層,該I型光吸收層的材質例如包含I型的InGaAs。要提到的是,該光吸收層13的材質可以參考用於現有光電二極體的已知光吸收層的材質。
本發明實施例之非擴散型光電二極體10的中間層14設置在該光吸收層13上且具有一第一邊界14A,其中該中間層14係一I型半導體層或一漸變層(graded refractive index layer;GRIN layer)。在一實施例中,該中間層14係該I型半導體層,例如該I型半導體層的材質包含I型的InP。在另一實施例中,該中間層14係該漸變層。要提到的是,該I型半導體層的材質可以參考用於現有光電二極體的已知I型半導體層的材質,該漸變層的材質可以參考用於現有光電二極體的已知漸變層的材質。
本發明實施例之非擴散型光電二極體10的倍增/窗層15設置在該漸變層14上且具有一第二邊界15A,其中在俯視圖中(如第1B圖所示),該第一邊界14A環繞該第二邊界15A,以及該第一邊界14A與該第二邊界15A之間的距離大於或等於1微米。在一實施例中,該倍增/窗層15係一P型倍增/窗層,例如該P型倍增/窗層的材質包含P型的InAlAs。在另一實施例中,該第一邊界14A與該第二邊界15A之間的距離介於1微米至15微米之間。在又一實施例中,該第一邊界14A與該第二邊界15A之間的距離介於2微米至15微米之間。
這邊要提到的是,本發明實施例之非擴散型光電二極體10的至少一特點在於中間層14與倍增/窗層15之間的邊界關係,其可用於改善非擴散型光電二極體的暗電流。具體而言,以俯視觀之(如第1B圖所示),該倍增/窗層15的位置與該中間層14的位置重疊,並且該倍增/窗層15的面積小於該中間層14的面積(即,倍增/窗層15與中間層14之間定義出一平台(mesa)的區域)。換言之,在非擴散型光電二極體的俯視圖中(例如由上往下視之),該中間層14的面積由該第一邊界14A所環繞,該倍增/窗層15的面積由該第二邊界15A所環繞,因此該第一邊界14A環繞該第二邊界15A。另一方面,該第一邊界14A與該第二邊界15A之間的距離D大於或等於1微米。在一範例中,該距離D基本上指的是從該第一邊界14A上的任一點出發到達該第二邊界15A的最小距離。透過設定中間層14與倍增/窗層15之間的邊界關係(即距離D),可以改善(或降低)非擴散型光電二極體10的暗電流。詳細的實驗數據在後面段落描述。
在一實施例中,該非擴散型光電二極體10還包含一接觸層16,該接觸層16設置在該倍增/窗層15上。該接觸層16係一P型接觸層,以及該P型接觸層的材質包含P型的InAlAs。
另外要提到的是,本發明實施例的非擴散型光電二極體10還可能包含任何已知的光電二極體中可能設置的層狀結構或器件,例如反射層、充電層、鈍化層18、封裝層19、金屬接點17等。
以下舉出數個實施例與比較例,以證明本發明實施例之非擴散型光電二極體確實可以改善(或降低)暗電流。
實施例1
提供一N型基板(例如N-InP基板),依序在該N型基板上形成緩衝層(例如N
+型的InP層)、光吸收層(例如I型的InGaAs層)、中間層(例如I型半導體層(例如I型的InP層)或漸變層)、倍增/窗層(例如P型的InAlAs層)、以及接觸層(例如P型的InAlAs層),以形成實施例1之非擴散型光電二極體。之後,利用已知的半導體工藝(例如蝕刻工藝等),以使在俯視圖中,中間層的第一邊界環繞倍增/窗層的第二邊界,其中該第一邊界與該第二邊界之間的距離約為1微米。
之後,透過市售的電流測量儀器測量實施例1的暗電流。暗電流定義為光電二極體在未照光時,逆向電壓為-5V時的背景電流值,單位為安培(A)。測試結果請參照下表1。
表1
距離D(微米) | 暗電流 (A) | |
比較例1 | 0 | 6.51x10 -9 |
實施例1 | 1 | 4.34 x10 -9 |
實施例2 | 2 | 5.28 x10 -11 |
實施例3 | 3 | 2.17 x10 -11 |
實施例4 | 8 | 2.74505 x10 -11 |
實施例5 | 9 | 2.8427 x10 -11 |
實施例6 | 10 | 2.3436 x10 -11 |
實施例7 | 12 | 1.6275 x10 -11 |
實施例8 | 13 | 2.00 x10 -11 |
實施例9 | 15 | 1.59 x10 -11 |
實施例2至9
實施例2至9的製作方式大致上與實施例1相同,不同之處在於第一邊界與第二邊界之間的距離不同。實施例2至9的測試結果請參照上表1。
比較例1
比較例1的製作方式大致上與實施例1相同,不同之處在於第一邊界與第二邊界重合(即第一邊界與第二邊界之間的距離為0)。值得一提的是,比較例1在蝕刻過程中是直接蝕刻到光吸收層13,而不是在中間層14停止,所以中間層14的邊界與光吸收層13的邊界重合(如第2圖所示)。比較例1的測試結果請參照上表1。
從表1可知,相比於比較例1,實施例1大約降低了33.3%的暗電流,實施例2至9則降低了約99.1%~99.8%的暗電流。由此可見,實施例1至9確實具有改善暗電流的效果。此外,當距離D大於或等於2微米時,可以大幅減少暗電流。
另外要提到的是,本發明實施例中所使用的用語,例如基板、緩衝層、光吸收層、I型半導體層、漸變層、倍增/窗層、接觸層、反射層、充電層或金屬接點等,可以參考光電二極體相關領域的定義,故在本發明中不再贅述。
另外要提到的是,在第1B圖中的中間層以及倍增/窗層的形狀是圓形,但本發明實施例的中間層以及倍增/窗層的形狀並不以此為限制。
另外要提到的是,本發明中所使用的用語“倍增/窗層15”意思是,其可以稱為“倍增層”,也可以稱為“窗層”。也就是說,本文中所出現的倍增/窗層15可以與倍增層交換使用,也可以與窗層交換使用。
雖然本發明已以較佳實施例揭露,然其並非用以限制本發明,任何熟習此項技藝之人士,在不脫離本發明之精神和範圍內,當可作各種更動與修飾,因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。
