Description

超薄橋接與多晶粒超細間距補塊架構及其製造方法
發明領域
數個具體實施例有關於封裝半導體裝置。更特別的是,該等具體實施例有關於具有包括超薄橋接與多晶粒超細間距補塊架構之封裝基板的半導體裝置。
發明背景
過去數十年來,積體電路(IC)中之特徵的縮放已為在不斷增長之半導體工業背後的驅動力。縮放為越來越小的特徵致能提高功能單元在半導體裝置之有限不動產上的密度。不過,縮小IC中之特徵同時優化各裝置之效能的驅力並非沒有問題。
對資料中心事業而言,多個晶片/晶粒異質集成於封裝中很重要。以最低的功率和高帶寬密度互連這些晶片驅策封裝基板上的超細線路/空間/介層窗墊片。最近,嵌入式式橋接晶粒技術係針對伺服器產品的這項需要。不過,在多晶粒互連件的需求不斷增長下,封裝基板需要嵌入式額外橋接晶粒(例如,10個以上的橋接晶粒)以容納這些多個晶粒及多晶粒互連件。更重要的是,此類封裝基板的封裝組裝製程也需要用焊料將多個晶粒附接至這些額外橋接晶粒區,且想要有良率高及橋接晶粒凸塊補塊增加的結果。不過,此類製程需要附加組裝步驟及時間,且要求在這些封裝的大面積上面有精確的基板平整度控制。
這限制用於以焊料為基礎之嵌入式式橋接晶粒連接的橋接晶粒凸塊補塊。橋接晶粒凸塊補塊的這些限制產生數個主要封裝問題,包括少於預期的凸塊密度,這進一步導致晶粒的互連實體面積增加以及由於矽面積增加而使成本增加。此外,由於企圖解決這些補塊縮放限制及問題,現有技術也已使用矽中介件。關於多晶粒架構,矽中介件可能有超過兩倍(或更多)標線大小的尺寸,因此需要併接標線但是會有過多的成本以及增加的複雜度。
依據本發明之一實施例,係特地提出一種半導體封裝,其包含:在一高密度封裝(HDP)基板上的一橋接,其中,該橋接包括一混合層;在該橋接及該HDP基板上面的複數個晶粒,其中,該橋接耦接於該等複數個晶粒與該HDP基板之間,其中,該橋接用該混合層直接耦接至該等複數個晶粒中之兩個晶粒,其中,該橋接之該混合層的一頂面直接在該等複數個晶粒的底面上,以及其中,該橋接的一底面直接在該HDP基板的一頂面上;以及在該HDP基板上的複數個直通塑模穿孔(TMV),其中,該等複數個TMV使該HDP基板耦接至該等複數個晶粒,以及其中,該等複數個TMV有實質等於該橋接之一厚度的一厚度。
描述於本文的是具有封裝基板及超薄(或薄)橋接與多晶粒超細間距補塊架構的半導體封裝及形成此類半導體封裝的方法。根據一些具體實施例,描述於下文的半導體封裝及形成此類半導體封裝的方法可包括複數個晶粒、高密度封裝(HDP)基板、薄橋接、複數個第一直通塑模穿孔(TMV)、複數個第二TMV、及封裝基板。描述於本文的這些半導體封裝具體實施例在沒有焊球/焊接下組合HDP基板(例如,高密度(HD)-有機基板)與薄橋接(例如,薄嵌入式多晶粒互連件橋接(EMIB))且最小化橋接個數,以及用混合介電質/導電接合層(例如,二氧化矽/銅(SiO2 /Cu)接合層)致能薄橋接直接耦接(或附接)於HDP基板與晶粒之間。
如本文所使用的,「橋接」可指由適合形成此類互連橋接(例如,嵌入式多晶粒互連橋接(EMIB))之任何其他基板材料製成的矽互連橋接或互連橋接。因此,如本文所使用的,「薄橋接」(或「超薄橋接」)可指可具有約10微米至15微米之厚度及/或約等於或小於10微米之厚度的橋接。如上述,描述於本文的薄橋接不需要耦接至晶粒的焊球,反而此類薄橋接可用混合層(混合接合層)直接耦接(及/或可通訊地耦接)至晶粒。如本文所使用的,「混合層」(或混合接合層)可指由複數個導電墊片(或銅墊片)、介電質層(或二氧化矽層)及表面修整層(或錫(Sn)層)構成的薄層(或超薄層),在此該介電質層可圍繞該等導電墊片,在此該等導電墊片的頂面與用來隔離導電墊片之介電質層的頂面實質共面,且在此該表面修整層可直接設置(或塗覆)於該等導電墊片的頂面上。
例如,為了用混合層使無焊料薄橋接直接耦接至晶粒,該薄橋接可直接設置錫於薄橋接的薄銅墊片上,在此該超薄橋接的錫與晶粒的銅墊片直接反應(i)以實作於錫/銅金屬間化合物於該薄橋接與該等晶粒之間,以及(ii)以用混合接合製程或其類似者使薄橋接直接鎖定(或接合固定)至該等晶粒。根據一具體實施例,該混合接合製程可包括溫度加熱、壓力和減少大氣以實作該超薄橋接與該等晶粒之間的鎖定。應注意,如下述,若需要,該混合層可省略表面修整層。
描述於本文的組合式HDP基板及薄橋接有助於半導體封裝係藉由實質減少(或排除/緩和)如以上所述通常為現有技術所需的薄橋接總數。下述半導體封裝的具體實施例致能改善例如晶粒之輸入/輸出(I/O)電路的佈線及電力傳輸功能。描述於本文的具體實施例也為半導體封裝提供改良的翹曲效益。例如,該半導體封裝可實作於使熱膨脹係數(CTE)失配應力實質減少的臨時玻璃載體上,特別是在囊封層(或封膠層)加工步驟之後。
描述於本文的具體實施例提供現有封裝解決方案的改良,其係藉由排除基於焊料的橋接互連件(亦即,描述於本文的橋接(或EMIB)在沒有焊料連接(solder connection)下可耦接至另一組件以藉此提供改良的橋接補塊縮放,減少晶粒上的互連實體面積,以及降低組裝成本。再者,現有封裝解決方案的另一改良包括:排除昂貴矽中介層的需要以藉此減少整體封裝成本。這些半導體封裝進一步提供現有封裝解決方案的改良係藉由實作及組合無焊料橋接(或EMIB)互連件、橋接至玻璃補塊的混合接合(例如,二氧化矽/銅接合)、有實質減少之線路/間隔(L/S)(例如,小於2/2的L/S)的HDP基板佈線層、超細微影界定(litho)介層窗、以及零失準介層窗架構。

關於一具體實施例,薄橋接140可具有約10微米至15微米的厚度。在另一具體實施例中,薄橋接140可具有約等於或小於10微米的厚度。關於一具體實施例,橋接140的導電墊片141及介電質層142可具有約5微米的厚度。在另一具體實施例中,橋接140的導電墊片141及介電質層142可具有約等於或小於10微米的厚度。關於一具體實施例,橋接140的表面修整層143可具有約1微米至2微米的厚度。在另一具體實施例中,橋接140的表面修整層143可具有約等於或小於5微米的厚度。應注意,在有些替代具體實施例中,可省略表面修整層143,如圖2C所示。同樣地,在一具體實施例中,混合層141-143可具有約5微米至7微米的厚度;然而,在另一具體實施例中,混合層141-143可具有約等於或小於7微米的厚度。
另外,如圖1所示,TMV 122a-b可直接設置於HDP基板130之導電互連件131的頂面上/上面且與其耦接。例如,TMV 122a-b從HDP基板130之導電互連件131的頂面大約垂直延伸到晶粒110-112的底面(或晶粒110-112之複數個第二導電墊片151a-b的底面)。應注意,在一些具體實施例中,TMV 122a-b可能不在HDP基板130的導電互連件131上直接(或完美地)對齊。
在一具體實施例中,TMV 122a-b可由例如銅或其類似者的導電材料形成。在TMV 122a-b可經無電成長、封膠囊封(encapsu平坦化時,TMV 122a-b可用微影製程(或其類似者)形成。另外,TMV 122a-b可具有複數個第一TMV 122a與複數個第二TMV 122b。在一具體實施例中,第一TMV 122a可具有大於第二TMV 122b之寬度的寬度。此外,在一些具體實施例中,第一TMV 122a可具有錐形側壁,同時第二TMV 122b可具有實質垂直的側壁及/或可具有略呈錐形的側壁,其角度實質小於第一TMV 122a之錐形側壁的角度。

應注意,基於所欲封裝設計,半導體封裝100可包括較少個或附加的封裝組件。
圖2A至圖2L的橫截面圖根據一具體實施例圖示形成半導體封裝200的加工流程。在一具體實施例中,根據一些具體實施例,半導體封裝200可包括複數個晶粒210-212、HDP基板230、有混合層241-243的薄橋接240、複數個TMV 222a-b、及封裝基板202。圖示於圖2A至圖2L的加工流程形成實質類似以上在說明圖1時提及之半導體封裝100的半導體封裝200。同樣,半導體封裝200的組件實質類似以上在說明圖1時提及之半導體封裝100的組件。因此,如上述,封裝基板200的加工流程圖示能組合晶粒210-212、薄橋接240及HDP基板230的方法中之一種,因為利用TMV 222a-b及導電墊片255a-b,薄橋接240可用混合層241-243以及超細互連/佈線補塊直接耦接於HDP基板230與晶粒210-212之間,而不是焊料連接。
圖2A根據一具體實施例圖示半導體封裝200的橫截面。在一具體實施例中,半導體封裝200可包括設置於載體201上的黏著劑層261(或黏著膜、接合膜等等)。關於一具體實施例,載體201可為玻璃載體(或臨時玻璃面板載體)、金屬載體、及/或任何類似平坦剛性載體/基板。
另外,在一具體實施例中,複數個晶粒210-212可設置於黏著劑層261及載體201上面,在此晶粒210-212可互相毗鄰地定位且用黏著劑層261耦接至載體201。例如,晶粒210-212可以大約等於或小於50微米的晶粒至晶粒間隔互相毗鄰地設置。此外,如圖2A所示,晶粒210-212的頂面可直接設置於黏著劑層261上以使晶粒210-212耦接至載體201。晶粒210-212可實質類似以上在說明圖1時提及的晶粒110-112。同樣地,晶粒210-212可具有複數個第二導電墊片251a-b與介電質層255,在此第二導電墊片251a的寬度可大於第二導電墊片251b的寬度。
此外,如圖2A所示,第二導電墊片251a-b的頂面可在介電質層255的頂面上面突出。例如,第二導電墊片251a-b可過鍍(over-plate)成有約2微米至3微米高於介電質層之厚度的厚度。另外,在一具體實施例中,第二導電墊片251b可具有約等於或小於5微米的補塊,它可實作以用於橋接介面及HD互連件(例如,圖2E的TMV 222b)。儘管,在另一具體實施例中,第二導電墊片251a可具有約等於或大於25微米的補塊,它可實作以用於非橋接介面。這些經過鍍的第二導電墊片251a-b有助於緩和晶粒210-212之間的厚度差異,在此也可調整(或選擇)介電質層255的厚度以適應晶粒210-212之間的厚度差異。
圖2B根據一具體實施例圖示半導體封裝200的橫截面。在一具體實施例中,可平坦化經過鍍的第二導電墊片251a-b使得第二導電墊片251a-b的頂面與介電質層255的頂面實質共面。此平坦化製程也致能第二導電墊片251a-b彼此有實質相同的厚度,減少半導體封裝200的任何厚度差異。
在一具體實施例中,可用化學機械平坦化(CMP)製程或其類似者實作該平坦化。由於存在用作停止點的介電質層255,該平坦化製程可具有高度的準確度。在第二導電墊片251a-b平坦化後,第二導電墊片251a-b的暴露頂面可與介電質層255的頂面實質共面,但是輕微凹陷。例如,可選擇性地蝕刻第二導電墊片251a-b以建立低於介電質層255之頂面大約等於或小於0.5微米的輕微凹陷(或蝕刻不足),在此此輕微凹陷有助於橋接(例如,圖2D的橋接240)與第二及第三晶粒211-212保持鎖定,如以上所述及以下圖2D所示。
圖2C根據一具體實施例圖示半導體封裝200的橫截面。在一具體實施例中,複數個薄橋接240可直接設置於第二及第三晶粒211-212上(如圖2D所示)。薄橋接240可實質類似以上在說明圖1時提及的薄橋接140。因此,在一具體實施例中,薄橋接240可包括混合層241-243(如在圖2C右側的薄橋接240所示),在此混合層241-243由複數個導電墊片241、介電質層242及表面修整層243構成(例如,混合層241-243可包括銅/二氧化矽/錫的組合或其類似者)。在一具體實施例中,用飛刀加工製程(fly-cut process)或其類似者可平坦化在薄橋接240上面的導電墊片241及介電質層242。隨後,在這些具體實施例中,然後,用鍍錫製程或其類似者(例如,可用浸錫鍍覆法、電鍍及/或類似者實作該鍍錫製程),直接設置表面修整層243於導電墊片241的暴露頂面上面。再者,應注意,如圖2C所示,表面修整層243在介電質層242的頂面上面可突出。
在一替代具體實施例中,薄橋接240可包括混合層241’-242’(如在圖2C左側的薄橋接240所示),在此混合層241’-242’由複數個導電墊片241’及介電質層242’構成。在省略表面修整層243後,混合層241’-242’可實質類似混合層241-243。
圖2D根據一具體實施例圖示半導體封裝200的橫截面。關於一具體實施例,有混合層241-243的薄橋接240可設置於第二及第三晶粒211-212上面。在一具體實施例中,薄橋接240可精確地定位成其混合層241-243在第二及第三晶粒211-212之第二導電墊片251b上(亦即,在細補塊導電(或銅)墊片(輕微凹陷)上)面朝下。在這些具體實施例中,薄橋接240的表面修整層243及導電墊片241可為複數個鍍錫銅墊片。關於一具體實施例,用精確的拾放工具(或其類似者),可將薄橋接240的鍍錫銅墊片精確地放在第二及第三晶粒211-212的第二導電墊片251b上。此外,如上述,在大約以240°C至250°C加熱鍍錫銅墊片以在薄橋接240的導電墊片241與第二及第三晶粒211-212的各個第二導電墊片251b之間建立銅-錫-銅金屬間接合時,可在薄橋接240的鍍錫銅墊片上實作混合接合製程(或銅/二氧化矽-銅/二氧化矽混合接合製程)。因此,在這些具體實施例中,銅-錫-銅金屬間接合可鎖定(或牢牢地固定)薄橋接240於第二及第三晶粒211-212上。
圖2E根據一具體實施例圖示半導體封裝200的橫截面。在一具體實施例中,可實作微影圖案化及鍍覆製程(或其類似者)以設置(或鍍覆/形成)複數個TMV 222a-b直接於晶粒210-212的各個第二導電墊片251a-b上。該微影製程可包括如以下所述的數個步驟。例如,種子層可設置於晶粒210-212之第二導電墊片251a-b及介電質層255的暴露頂面上面。在一具體實施例中,該種子層可包括銅、鈦、彼等之任何組合、及/或類似者。該種子層可用濺鍍製程或其類似者形成。
在種子層設置後,在一具體實施例中,阻劑層可設置於該種子層上面。在一具體實施例中,該阻劑層可為乾膜阻劑(DFR)或其類似者。在一具體實施例中,用微影製程、雷射鑽孔製程、或其類似者可圖案化(或曝光/顯影)該阻劑層以形成介層窗開口。該等介層窗開口可暴露晶粒210-212之第二導電墊片251a-b在非橋接介面(或部份/區域)中的頂面。
在一些具體實施例中,導電材料(例如,銅)可設置(或鍍覆)於介層窗開口中以各自在晶粒210-212之第二導電墊片251a-b的暴露頂面上形成TMV 222a-b(或可經無電成長、隨後封膠囊封且加以平坦化的微影介層窗)。TMV 222a-b可稱為導電柱體/互連件。TMV 222a-b可實質類似以上在說明圖1時提及的TMV 122a-b。在一具體實施例中,為了確保完全填滿阻劑層的介層窗開口,TMV 222可過鍍於阻劑層的頂面上面。關於一具體實施例,TMV 222a-b可從第二導電墊片251a-b垂直延伸到/越過阻劑層的頂面。在一具體實施例中,可用電鍍製程或其類似者來形成TMV 222a-b。
在一具體實施例中,在過鍍TMV 222a-b時,可平坦化經過鍍的TMV 222a-b使得TMV 222a-b的頂面與阻劑層的頂面實質共面。此平坦化製程也致能TMV 222a-b彼此有實質相同的厚度,減少半導體封裝200的任何厚度差異。例如,在TMV 222a-b平坦化後,TMV 222a-b的暴露表面可與橋接240的暴露表面實質共面。在一具體實施例中,該平坦化可用CMP製程或其類似者實作。由於存在用作停止點的阻劑層,該平坦化製程可具有高度的準確度。最後,可用任何適當製程剝除該阻劑層,例如灰化、濕式剝除或其類似者。在移除阻劑層後,石暴露種子層的數個部份。同樣地,可用蝕刻製程或其類似者蝕刻經暴露的種子層。
圖2F根據一具體實施例圖示半導體封裝200的橫截面。關於一具體實施例,囊封層280可設置於TMV 222a-b、有介電質層242的薄橋接240、有導電墊片251a-b及介電質層255的晶粒210-212、以及黏著劑層261上面。在一具體實施例中,可設置囊封層280以覆蓋TMV 222a-b的頂面。在一具體實施例中,囊封層280可為封膠層及/或任何類似囊封材料(s)。關於一具體實施例,封膠層280可包括有一或多個填料的環氧樹脂(例如,軟環氧樹脂,硬環氧樹脂,不透明環氧樹脂等等)。在一具體實施例中,囊封層280可經壓縮模製、壓合或其類似者而成。
囊封層280可實質類似以上在說明圖1時提及的囊封層180。在一具體實施例中,可平坦化(或研磨)囊封層280使得TMV 222a-b的頂面與囊封層280及/或橋接240的頂面實質共面。另外,平坦化/研磨囊封層280以暴露TMV 222a-b及/或橋接240的頂面。在一具體實施例中,該平坦化可用CMP製程或其類似者實作。
圖2G根據一具體實施例圖示半導體封裝200的橫截面。在一具體實施例中,HDP基板230可設置於囊封層280、TMV 222a-b及橋接240的頂面上面。同樣地,HDP基板230的橋接介面可直接設置於橋接240的暴露表面上,藉由有混合層241-243的橋接240夾在晶粒211-212與HDP基板230之間。HDP基板230可實質類似以上在說明圖1時提及的HDP基板130。同樣地,HDP基板230可包括複數個導電互連件231與複數個第一導電墊片218。HDP基板230的導電互連件231可使TMV 222a-b及晶粒210-212導電地耦接至第一導電墊片218。
在一具體實施例中,第一導電墊片218可用如以上所述的微影製程設置(或鍍覆)於HDP基板230的頂面上。應注意,在如圖2L所示翻轉半導體封裝200後,第一導電墊片218最終可位於HDP基板230下面,耦接至HDP基板230的底面,且類似以上在說明圖1時提及的第一導電墊片118。關於一具體實施例,HDP基板230可包括有L/S約等於或小於2/2之導電跡線(或線路)的一或多個RDL層、微影介層窗、零失準介層窗、及/或約等於或小於18微米的介層窗墊片。在一具體實施例中,HDP基板230的第一導電墊片218可具有約等於或大於80微米的補塊。
圖2H根據一具體實施例圖示半導體封裝200的橫截面。在一具體實施例中,囊封層280可進一步設置於第一導電墊片218、HDP基板230、及現有囊封層280上面以完全圍繞(或圍封/嵌入式)HDP基板230、橋接240及晶粒210-212。囊封層280可實質類似以上在說明圖2F時提及的囊封層280。另外,在一具體實施例中,可平坦化囊封層280以暴露第一導電墊片218的頂面,在此第一導電墊片218的頂面可與囊封層280的頂面實質共面。如上述,囊封層280的平坦化可用CMP製程或其類似者。

雖然圖1中將一組晶粒110-112設置於一HDP基板130及一薄橋接140上面且與其耦接,然而在圖3中,用超細補塊將兩組晶粒310-312設置於各個HDP基板330及薄橋接340上面且與其可通訊地耦接,藉此添加額外的所欲IC,例如改善半導體封裝300之整體效能的額外晶粒,同時只使用有超薄混合層341-343的一個薄橋接340從而半導體封裝300維持實質減少的整體厚度(或z高度)。
再者,雖然薄橋接140在圖1中有不具有任何TSV的混合層141-143,薄橋接340在圖3中可實作具有TSV的混合層341-343,藉此直接供電給各個晶粒310-312及/或基板301以改善半導體封裝300的整體電力效能。儘管,在各補塊中,圖示兩個晶粒310-312、一個HDP基板330、及一個薄橋接340,然而應瞭解,在各補塊中,任意複數個晶粒310-312、HDP基板330、及薄橋接340可設置(或安置)於基板301上/上面。應注意,半導體封裝300可從兩個補塊(或封裝)切單成個別補塊(或封裝),如以上在說明圖2K至圖2L時所示/所述。
