然而,本揭露的態樣不受本文中所闡述的態樣限制。藉由參考下文給出的本揭露的詳細描述,本揭露的以上及其他態樣對於本揭露涉及的所屬技術領域中具通常知識者而言將變得更加顯而易見。
圖1為用於說明根據示例性實施例的半導體封裝的示意性佈局圖。圖2為沿著圖1的線I-I截取的示意性橫截面圖。圖3為用於說明圖2的區A的放大圖。圖4至圖9為圖2的示意性平面圖。為方便說明,在圖4至圖9中僅繪示圖2的第一對準鍵及第二對準鍵。
如本文中所使用,為易於描述,可使用空間相對術語(諸如「在...之下」、「在...下方」、「下部」、「在...上方」、「上部」以及類似術語)來描述一個元件或特徵與如圖中所示出的另一(些)元件或特徵的關係。應理解,除了圖中所描繪的定向之外,空間相對術語亦意欲涵蓋裝置在使用或操作中的不同定向。舉例而言,若將圖中的裝置翻轉,則描述為「在其他元件或特徵下方」或「在其他元件或特徵之下」的元件隨後將定向「在其他元件或特徵上方」。因此,術語「在...下方」可涵蓋在...上方及在...下方的定向兩者。裝置可以其他方式定向(旋轉90度或處於其他定向),且本文中所使用的空間相對描述詞同樣可相應地進行解釋。
應理解,儘管在本文中可使用術語第一、第二、第三等來描述各種元件、組件、區、層及/或區段,但這些元件、組件、區、層及/或區段不應受這些術語限制。除非上下文另有指示,否則這些術語僅用於將一個元件、組件、區、層或區段與另一元件、組件、區、層或區段區分開,例如作為命名常規。因此,在不脫離本發明的教示的情況下,可將下文在本說明書的一個章節中所論述的第一元件、組件、區、層或區段稱為本說明書的另一章節中或申請專利範圍中的第二元件、組件、區、層或區段。另外,在某些情況下,即使在本說明書中未使用「第一」、「第二」等來描述術語,但在申請專利範圍中仍可將所述術語稱為「第一」或「第二」,以將不同的所主張元件彼此區分開。
參看圖1至圖4,根據示例性實施例的半導體封裝可包含第一半導體晶片100、第一鈍化層130、第二鈍化層230、第二半導體晶片200以及模製層600。
第一半導體晶片100及第二半導體晶片200各自可為記憶體半導體晶片。記憶體半導體晶片可為例如揮發性記憶體半導體晶片,諸如動態隨機存取記憶體(Dynamic Random Access Memory;DRAM)或靜態隨機存取記憶體(Static Random Access Memory;SRAM);或非揮發性記憶體半導體晶片,諸如相變隨機存取記憶體(Phase-change Random Access Memory;PRAM)、磁阻式隨機存取記憶體(Magnetoresistive Random Access Memory;MRAM)、鐵電隨機存取記憶體(Ferroelectric Random Access Memory;FeRAM)或電阻式隨機存取記憶體(Resistive Random Access Memory;RRAM)。第一半導體晶片100可為例如緩衝半導體晶片。
或,第一半導體晶片100可為邏輯半導體晶片,且第二半導體晶片200可為記憶體半導體晶片。舉例而言,第一半導體晶片100可為控制諸如電連接至第一半導體晶片100的第二半導體晶片200的輸入及輸出的操作的控制器半導體晶片。

第一接合墊132可放置於第一佈線結構120的第一佈線區121上。舉例而言,第一接合墊132可在第二方向DR2上與第一佈線區121交疊。第一接合墊132可電連接至第一佈線圖案124。
第一對準鍵134可放置於第一佈線結構120的第一對準區123上。舉例而言,第一對準鍵134可在第二方向DR2上與第一對準區123交疊,且可不與第一佈線區121交疊。亦即,第一對準鍵134在第二方向DR2上可不與第一佈線圖案124交疊。第一對準鍵134可在第一方向DR1上與第一佈線圖案124間隔開。
在一些實施例中,第一對準鍵134可包含與第一接合墊132相同的材料。第一接合墊132在第二方向DR2上的厚度H11可與第一對準鍵134在第二方向DR2上的厚度H12實質上相同。
第二半導體晶片200可放置於第一半導體晶片100上。第二半導體晶片200可在第二方向DR2上與第一半導體晶片100間隔開。
第二佈線結構220可放置於第二半導體基底210上。第二佈線結構220可與第一佈線結構120相對。第二佈線結構220可例如在第二方向DR2上與第一佈線結構120相對。第二佈線結構220可包含第二佈線絕緣膜222及位於第二佈線絕緣膜222中的第二佈線圖案224。第二佈線圖案224可自第二半導體基底210的底面依序堆疊。
第二佈線結構220可包含放置第二佈線圖案224的第二佈線區221及未放置第二佈線圖案224的第二對準區223。第二佈線區221可放置於第二對準區223之間。
在一些實施例中,第二對準區223可放置成鄰近於第二佈線結構220的兩個角。第二對準區223可在第一方向DR1上放置於第二佈線結構220的兩個角處。第二對準區223可彼此成對角線地相對放置。第二對準區223可在第一方向DR1上彼此分開地放置。第二佈線區221可放置於在第一方向DR1上彼此間隔開的第二對準區223之間。
第二鈍化層230可放置於第二佈線結構220上。第二鈍化層230可放置於第二佈線結構220與第一鈍化層130之間。第二鈍化層230可包含第二接合墊232及第二對準鍵234。第二接合墊232與第二佈線結構220相接觸的表面可放置於同第二對準鍵234與第二佈線結構220相接觸的表面相同的平面上。舉例而言,第二接合墊232及第二對準鍵234的下表面可彼此共面,且第二接合墊232及第二對準鍵234的上表面可彼此共面。第二接合墊232及第二對準鍵234可例如在第二佈線結構220上在第一方向DR1上彼此間隔開。以另一種方式,第二鈍化層230可包覆第二對準鍵234的側面及第二接合墊232的側面。舉例而言,第二鈍化層230可環繞第二對準鍵234的側面及第二接合墊232的側面,且接觸第二對準鍵234的側面及第二接合墊232的側面。
在一些實施例中,第二對準鍵234可包含與第二接合墊232相同的材料。第二接合墊232在第二方向DR2上的厚度H21可與第二對準鍵234在第二方向DR2上的厚度H22實質上相同。
第二接合墊232可放置於第二佈線結構220的第二佈線區221上。舉例而言,第二接合墊232可在第二方向DR2上與第二佈線區221交疊。第二接合墊232可電連接至第二佈線圖案224。
第二接合墊232可與第一接合墊132直接接觸。第一接合墊132及第二接合墊232可包含相同金屬。在一些實施例中,第一接合墊132及第二接合墊232可包含銅(Cu)。第一接合墊132及第二接合墊232可藉由使銅例如經由高溫退火製程相互擴散而耦接。第一接合墊132及第二接合墊232可包含可彼此耦接的材料(例如金(Au)),而不限於銅。亦即,第二接合墊232可直接耦接至第一接合墊132。
第二鈍化層230可與第一鈍化層130直接接觸。第一鈍化層130及第二鈍化層230可包含相同材料。在一些實施例中,第一鈍化層130及第二鈍化層230可包含氧化矽。第一鈍化層130及第二鈍化層230可藉由例如高溫退火製程彼此聯接,且可藉由矽與氧的共價鍵而具有更強的接合強度。第一鈍化層130及第二鈍化層230可包含可彼此耦接的絕緣材料(例如SiCN),但不限於氧化矽。亦即,第二鈍化層230可直接聯接至第一鈍化層130。
因此,第一半導體晶片100及第二半導體晶片200可接合。亦即,第一半導體晶片100及第二半導體晶片200可藉由Cu-Cu混合接合彼此聯接。因此,由於根據一些實施例的半導體封裝不需要用於填埋半導體晶片之間的間隙的間隙填充製程,因此可防止間隙填充缺陷。另外,當焊球之間的距離隨著半導體封裝的尺寸的減小而減小時,可出現諸如彼此鄰近的焊球彼此聯接的缺陷。然而,由於根據一些實施例的半導體封裝使用Cu-Cu混合接合而非焊球,因此有可能防止焊球的缺陷性聯接,且進一步減小半導體封裝的厚度。
第二對準鍵234可放置於第二佈線結構220的第二對準區223上。舉例而言,第二對準鍵234可在第二方向DR2上與第二對準區223交疊,且可不與第二佈線區221交疊。亦即,第二對準鍵234在第二方向DR2上可不與第二佈線圖案224交疊。第二對準鍵234可在第一方向DR1上與第二佈線圖案224間隔開。
第二佈線區221可放置於第一佈線區121上,且第二對準區223可放置於第一對準區123上。因此,第一對準鍵134及第二對準鍵234可在第一方向DR1上與第一佈線圖案124及第二佈線圖案224間隔開。舉例而言,第二對準鍵234可與第一佈線圖案124間隔開第一距離D1。第二對準鍵234可與第二佈線圖案224間隔開第二距離D2。第一距離D1與第二距離D2可實質上彼此相同或不同。
在一些實施例中,在第一對準鍵134及第二對準鍵234中的任一者與第一佈線圖案124及第二佈線圖案224中的任一者之間的距離當中的最近距離可為5微米或小於5微米。舉例而言,第一距離D1及第二距離D2可為5微米或小於5微米。
第一對準鍵134及第二對準鍵234可具有彼此不同的形狀。舉例而言,參看圖4,第一對準鍵134可具有四邊形形狀,且第二對準鍵234可具有方框形狀,包含具有四邊形形狀的內壁234_IW及外壁234_OW。以另一種方式,第一對準鍵134不包含內部的開口,且第二對準鍵234可包含內部的暴露出第二佈線結構220的至少一部分的開口234_O。
第一對準鍵134可放置於第二對準鍵234的內壁234_IW內部。第一對準鍵134可放置於第二對準鍵234的開口234_O內部。第一對準鍵134與第二對準鍵234在第二方向DR2上可不彼此交疊。當在平面圖中觀察時,第二對準鍵234可與第一對準鍵134間隔開,且可包覆第一對準鍵134的外周。舉例而言,第二對準鍵234可環繞第一對準鍵134的外周。
在一些實施例中,第一對準鍵134與第二對準鍵234在第一方向DR1上的間隔距離D31及第一對準鍵134與第二對準鍵234在第三方向DR3上的間隔距離D32可為5微米或小於5微米。
在第二對準鍵234的外壁234_OW之間的在第一方向DR1上的距離W21可大於第一對準鍵134在第一方向DR1上的厚度W11,且在第二對準鍵234的外壁234_OW之間的在第三方向DR3上的距離W22可大於第一對準鍵134在第三方向DR3上的厚度W12。第二對準鍵234的外壁234_OW之間的在第一方向DR1上的距離W21可與第二對準鍵234的外壁234_OW之間的在第三方向DR3上的距離W22相同或不同。第一對準鍵134在第一方向DR1上的厚度W11可與第一對準鍵134在第三方向DR3上的厚度W12相同或不同。
在一些實施例中,第一對準鍵134在第一方向DR1上的厚度W11及第一對準鍵134在第三方向DR3上的厚度W12可為5微米或小於5微米。第二對準鍵234的外壁234_OW與內壁234_IW之間的在第一方向DR1上的距離W31及第二對準鍵234的外壁234_OW與內壁234_IW之間的在第三方向DR3上的距離W32可為5微米或小於5微米。第二對準鍵234的外壁234_OW之間的在第一方向DR1上的距離W21及第二對準鍵234的外壁234_OW之間的在第三方向DR3上的距離W22可為20微米或小於20微米。
當第二半導體晶片200堆疊於第一半導體晶片100上時,可基於第一對準鍵134及第二對準鍵234來確認第一半導體晶片100與第二半導體晶片200的對準。此時,當第一對準鍵134及/或第二對準鍵234與第一佈線圖案124及/或第二佈線圖案224在第二方向DR2上交疊時,由於第一佈線圖案124及/或第二佈線圖案224而難以確認第一對準鍵134及/或第二對準鍵234的對準。因此,由於可能未即時確認第一半導體晶片100與第二半導體晶片200的對準,因此基於在聯接之前的測量資料或基於在聯接之後對樣本晶片的斷裂分析來計算第一半導體晶片100與第二半導體晶片200的對準的準確性。
然而,在根據示例性實施例的半導體封裝中,第一對準鍵134及第二對準鍵234在第二方向DR2上不與第一佈線圖案124及第二佈線圖案224交疊。因此,在半導體封裝中,當第二半導體晶片200堆疊於第一半導體晶片100上時,可確認第一對準鍵134與第二對準鍵234的對準。亦即,藉由自頂部確認第一對準鍵134及第二對準鍵,第二半導體晶片200可在第一半導體晶片100上更精確地對準。此外,由於第一對準鍵134與第二對準鍵234具有不同形狀,因此第一半導體晶片100及第二半導體晶片200可與第一對準鍵134及第二對準鍵234區分開。因此,由於第一半導體晶片100及第二半導體晶片200在半導體封裝中更精確地對準及接合,因此可提高產品可靠性。

圖19至圖21為用於說明根據示例性實施例的用於製造半導體封裝的方法的中間階段圖。
參看圖19,可形成包含第一半導體基底110及放置於第一半導體基底110上的第一鈍化層130的晶圓W,所述第一半導體基底110包含第一連接墊112及第一佈線結構120。第一佈線結構120可形成為包含第一佈線絕緣膜122及位於第一佈線絕緣膜122中的第一佈線圖案124,且第一鈍化層130可形成為包含第一接合墊132及第一對準鍵134。第一穿透電極114可形成為穿透第一半導體基底110。第一連接端105可形成於第一連接墊112上。儘管圖19至圖21繪示第一半導體晶片100形成於晶圓W上,但本揭露不限於此。在一些示例性實施例中,插入件可形成於晶圓W上。
第一連接端105形成於其上的晶圓W附接至載板基底1上。晶圓W可附接至載板基底1上,使得第一連接端105面向載板基底1。晶圓W可藉由黏著層2附接至載板基底1上。黏著層2可環繞第一連接端105。
隨後,參看圖20,具有形成於底面上的第二鈍化層230的第二半導體晶片200可形成於第一鈍化層130上。第二半導體晶片200可包含第二佈線結構220。第二佈線結構220可形成為包含第二佈線絕緣膜222及位於第二佈線絕緣膜222中的第二佈線圖案224,且第二鈍化層230可形成為包含第二接合墊232及第二對準鍵234。此時,第二半導體晶片200可基於第一鈍化層130中所包含的第一對準鍵134及第二鈍化層230中所包含的第二對準鍵234而在晶圓W上對準。由於第一對準鍵134不與第一佈線圖案124交疊且第二對準鍵234不與第二佈線圖案224交疊,因此可確認第一對準鍵134與第二對準鍵234的對準。舉例而言,當第一對準鍵134與第二對準鍵234間隔開且環繞第二對準鍵234的外周時,藉由使用紅外線相機來確認第二半導體晶片200的第二對準鍵234是否放置於第一半導體晶片100的第一對準鍵134中,可確認第二半導體晶片200與第一半導體晶片100的對準,且第二半導體晶片200可基於其而在晶圓W上對準。
隨後,第一接合墊132及第二接合墊232可使用高溫退火製程或類似者直接聯接,且第一鈍化層130及第二鈍化層230可直接聯接。
隨後,參看圖21,模製層600可形成於第一半導體晶片100上。模製層600可放置於第一半導體晶片100的頂面上,且可環繞第二半導體晶片200的側面。
隨後,參看圖1,可切割第一半導體晶片100,且可移除載板基底1及黏著層2以形成半導體封裝。
當將晶圓聯接至晶圓上以形成半導體封裝時,由於難以只選擇及聯接不良晶粒,因此晶圓亦可聯接至不良晶粒上。因此,可降低半導體封裝的製造製程的產量。當將晶粒聯接至晶粒上以形成半導體封裝時,由於可選擇良好晶粒且可聯接晶粒,因此可提高半導體封裝的製造製程的產量。然而,由於晶粒聯接至晶粒上,因此可降低生產率。
可藉由將晶粒聯接至晶圓上來形成根據示例性實施例的半導體封裝。當將晶粒聯接至晶圓上時,由於選擇良好晶粒且將其附接至晶圓,因此可進一步提高或提昇半導體封裝的製造製程的產量及生產率。
綜上所述,所屬技術領域中具通常知識者應瞭解,在不實質上脫離本揭露的原理的情況下,可對較佳實施例進行許多變化及修改。因此,本揭露的所揭露的較佳實施例僅在一般及描述性意義上使用,而非出於限制目的。
