1338927 【發明所屬之技術領域】 本發明大體上係有關於一半導體積體電路(1C)封裝。 詳言之,本發明係有關於一種改良的多晶片球柵陣列(BGA) 封裝,其可與相同尺寸或類似尺寸的1C晶片一起使用,且 有關於該改良的多晶片球柵陣列(BGA)封裝的製造方法。 【先前技術】 半導體為具有絕緣體及導體特性的物質。在現今的技 術中’半導想物質已變得極為重要,因為其已成為電晶趙、 二極想’及其它固態元件的基礎。半導體通常是由錄或石夕 所製’但亦可使用场及銅氡化物及其它材質。當被適當地 製造時,半導體在一方向上的導電性會比在另一方向上的 導電性佳。 目前 1C封裝工業產生一組
浮現的電子產品應用對於 挑戰》當1C晶片被製造且被包封在半導體封裝中時,它們
即可被使用在許?不同的電子設備巾。使料Μ封裝的 電子裝置在最近幾年已大幅地成長且包括行動電話、可機 式電腦、手持式裝置,以及許多其它的裝置。4一種裝置 典型地都包括-主機板’許多半艘封裝被因定在該主機板 上用以提供多種電子功能。隨著消費者需求增>,這此裝 置的尺寸變小且成本被降低…,曰益期望的是縮小 被集成的半導體封裝的輪廓,使得電子系統可整 精巧的裝置及產品中。 1两 3 1338927 最近,多晶片封裝,其為IC封裝的特殊領域且其係有 關於將複數個半導想晶片組合在單—Ic封裝内,已愈來愈 流行。此一流行是受到雇業對於將更多功能性碎晶片在較 低的成本下封裝成更小封裝的需求所驅動。將兩個或更多 個矽晶片封裝在單一封裝内可降低相關成本亦可降低在
其上安裝有ic封裝之印刷電路板上的面積需求。此外,多 晶片封裝可讓晶片更靠近且將該封裝内之晶片與晶片之間 的電子訊號路徑縮短^這可縮短電子訊號的傳遞時間並改 善整體的速度與性能。又’多晶片封裝可節省相當大的安 裝面積’因而可提高有價值之佈局彈性。 與BGA技術相結合的多晶片封裝被視為介於碎密 度及性能’與封裝及板/基材結構的材料能力之間的擴大差 距的解決方案的一部分。多晶片封裝可被視為標準的單一 晶片封裝,其被加以修改以同時容納複數個晶片及被動元 件以提供使用者更高的功能性整合^典型地,大多數的多 晶片封裝包含二至六個晶片且封裝成為一傳統的Bga。
多晶片封裝的好處有很多。例如,其可在無法經由衫 集成來符合的時間-對-市場窗口中,提供更大的功能性^ 有效地使用多晶片封裝可讓密度及性能提高且降低在電路 板或系統層級的尺寸與重量,同時可減少電路板面積及路 徑複雜度。通常’板層縮小可進一步降低使用多晶片封装 的成本。多晶片封裝的其它好處包括透過使用最有經濟效 益的矽解決方案之設計最佳化,及使用不同的半導體技 術、晶粒形狀或晶片種類於相同封裝中進行封裝組合 4 1338927 力。 ic封裝這樣的特殊領域可提高高速設計、組裝處理及 包含在多晶片封裝内的材料之價值。用此方式將多片晶片 封裝在一起亦可便於進行堆疊的晶粒或多層、兩側式封裝 (two-sided package)的組裝製程。使用此技術可輕易地將 不同的互連線(interconnection)技術,如覆晶接合或打線接 合(wire bond),結合至多晶片封裝》 典型地,在多晶片封裝中,構件晶片被垂直地堆疊或 可被並排設置在封裝本體内。第1 A及1 B圖分別顯示使用 堆疊式或並排式結構之多晶片封裝例。介於晶片與封裝的 外部接腳之間的互連線,可藉由傳統的打線接合,如第1A 及1B圖所示,覆晶方式的凸塊、導線接合(lead bonding) ’ 或經由上述技術的組合來完成。垂直堆疊式的晶片需要的 封裝本體面積較小,所以在印刷電路板上所佔的面積比並 排式晶片小》因此,堆疊式晶片通常是多晶片封裝中較佳 的方式。然而’在與將大小相近的晶片堆疊有關,及與某 些結合塾佈局设計有關的晶片堆昼上,則存在許多基本上 的困難。
如第1A圖所示的,傳統的晶片堆疊技術包含將一第 一 ic晶片115八安裝在一基材1〇1上,然後將一第二晶片 116A安裝在該第一晶片U5A的頂部上。經由數條將該第 一晶片Π5Λ的上表面的結合墊(未帝出)連接至基材ι〇1 的上表面上的導電材料103的細線121A,將第一晶片11 5A 耦合至該基材上導電材料。此方法需要該第一晶片n5A 1338927 的上表面包括結 1 2 1 A。因此,第二 的足跡(footprint) 一樣大或比它還大 空間給連接至該細 如第1B圖所 於該封裝本體内。 安裝在一基材101 該第一晶片1 1 5 B : 晶片 Π 6 B兩者是 116B上表面上的鸟 上的導電材料103 因此,晶片堆 設計之大小相近的 片的結合整會被上 對具有非周邊 墊是位在晶片表面 擋的機率更高,即 對於這些與晶 行的解決方案》本 大幅地對於封裝本 明亦可提高良率。 良率係指一最 件的比例。良率可 合墊在内的某部分能夠連接至細線 晶片1 1 6 A必需具有比第一晶片11 5 A小 B如果第二晶片11 6 A與第一晶片11 5 a 的話,該第一晶片1 1 5 A的上表面就沒 線1 2 1 A的結合墊用。 示的,多晶片封裝使用並排設置的晶片 此封裝技術包含將一第一 1C晶片ΐι5Β 上’然後將一次級IC晶片1 1 6 B安裝在 参的基材101上。第一晶片115B與第二 藉由數條將第一晶片115B及第二晶片 『合墊(未示出)連接至基材101的上表面 的細線121B來耦合至基材1〇1。 疊技術的一項限制為具周邊結合墊佈局 晶片不能直接彼此堆疊,因為下方的晶 方晶片阻擋。 結合墊佈局設計的晶片而言,即,結合 的中心處者’下方晶片上的結合墊被阻 使是較小的晶片疊在上方亦然。 片堆疊有關的問題,本發明提供一種可 發明增加半導體IC的功能性容量,同時 趙面積及印刷電路板空間的需求。本發 終封裝之可用構件辦最初送來處理的構 在處理中的任何輸入-輸出階段被取得,
6 1338927 且必需被小心地界定與瞭解。通常,一晶圓的良率並不是 很高。因此,在進行封裝之前確認哪些晶片是有缺陷的及 哪些晶片是有作用的是很重要的。經過一測試處理,有缺 陷的晶片被拋棄被被修補使得只有那些有作用的晶片被封 裝到最終的電子裝置中。 在晶片被封裝之前知道該晶片是否正常變得愈來愈重 要,因為有愈來愈多的晶片被封裝在一多晶片模組内。在 沒有測試下,複數個晶片的個別良率的複合效果對於多晶 片模組而言可能會造成良率非常的低。因此,對於能夠在 完全組裝之前進行個別晶片的測試之方法存在著需求。 本發明亦提供方便的產品測試。其可讓製造商在將晶 片安裝到一基礎基材結構上之前測試該晶片的功能狀態。 這可降低將壞的晶片與好的晶片結合到多晶片封裝中(這 通常是不可逆的製程)的風險,進而提高該封裝之最終良 率。 【發明内容】 一種依據本發明的一第一舉例性實施例的 B G A封裝 包含一基礎1C結構及多條接線(wires)。該基礎1C結構包 含一基礎基材,該基材具有一開口縱向地穿過它。該基礎 基材包含一第一面及一第二面,其與第一面相對。該基礎 基材亦包含多個介層孔(via)穿透於第一面與第二面之 間,其中該導電部分亦延伸穿過介層孔。該基礎結構更包 含一設置在該第一與第二面上的導電部分。該基礎結構更 7 1338927 包含一層焊劑罩幕層,其設置在該第一及第二面 分之其餘空白部分上,留下該導電部分之沒有焊 指定區域。該基礎1C結構亦包含一第一半導體邊 一半導體晶片包含一第一面;一第二面,其與第-及多個側邊》該第一半導體晶片亦包含複數個結 致上沿著該第一半導體晶片的第二面的中心軸 齊。該第一半導體晶片的第二面安裝到該基礎結 得該等結合墊可經由該基礎基材上的開口來接近 封裝更包含一第一複數條接線。每一條接線都將 導體晶片的一個結合墊經由該開口連接到該基礎 二面上的導電部分的指定區域。 依據本發明的第一舉例性實施例的一個態樣 封裝更包含一次級1C結構。該次級1C結構包含 及一第二面,其與第一面相對。該次級1C結構亦 二半導體晶片,其包含一第一面、一第二面及複 墊,其大致上沿著該第二半導體晶片的第二面的 向地對齊。該第二半導體晶片的第二面安裝到該 上,使得該等結合墊可經由該次級基材上的開口 該次級1C結構亦包含一第二複數條接線,每一條 該第二半導體晶片的一個結合墊經由該開口連接 基材的第二面上的導電部分。該次級1C結構更包 其填充在該開口内,包圍該第二複數條接線並覆 基材的第二面上的導電部分。該次級1C結構安裝 1C結構上。依據該第一舉例性實施例的此態樣
