Description

封裝結構之製法
本發明係有關一種封裝結構之製法,尤指一種能提高整體產能與降低整體成本之封裝結構之製法。
在現行打線接合式(Wire Bond)的半導體封裝技術中,係將半導體晶片之非作用面接置在一封裝基板上,而該半導體晶片之作用面上設有複數電極墊,且該封裝基板接置該半導體晶片之表面並具有複數打線墊,而藉由焊線對應電性連接各該電極墊與打線墊,以令該半導體晶片電性連接該封裝基板。
習知之封裝基板係於一核心板及對稱形成於其兩側之線路增層結構所組成,但因使用核心板將導致導線長度及整體結構厚度增加,而難以滿足電子產品功能不斷提昇且體積卻不斷縮小之需求,遂發展出無核心層(coreless)結構之封裝基板,以符合縮短導線長度及降低整體結構厚度、及因應高頻化、微小化的趨勢要求。
又習知之打線接合式封裝結構之製法係先提供一已完成前段製程且具有多層線路連接結構之整版面基板本體,於其最外層線路具有複數打線墊與絕緣保護層,且該絕緣保護層中形成複數開孔,令該增層結構之各該打線墊對應外露於各該開孔,並於各該外露之打線墊上形成表面處理層,而成為一整版面封裝基板(panel);接著,將該整版面封裝基板切割成複數封裝基板單元(unit)或複數封裝基板條(strip),其中各該封裝基板條係包含複數封裝基板單元;最後,再運送至封裝廠進行後續之置晶、打線接合、封裝、及/或切單(singulation)等步驟。
惟,若將該整版面封裝基板切割成複數封裝基板單元後,再進行置晶、打線接合與封裝步驟,則因為一次僅能針對單一個封裝基板單元作處理,因而產能降低,且增加整體成本;又若將該整版面封裝基板切割成複數封裝基板條後,再進行置晶、打線接合、封裝與切單步驟,則因為該封裝基板條所保留的邊框佔用不少有效面積,因而形成材料成本的浪費。
另一方面,隨著封裝基板的整體厚度愈來愈薄,對於封裝基板單元或封裝基板條進行置晶或封裝等加工步驟將更加困難。
然而,若不先將整版面封裝基板切割成複數封裝基板單元或複數封裝基板條,而直接以整版面封裝基板來進行置晶、打線接合、封裝、及切單等步驟,則必須購置較大之機台,因而造成整體設備成本的上升;再者,整版面封裝基板的大面積對位的精度較低,容易使得最終的封裝結構單元有較大的製程誤差,進而影響整體良率。
因此,如何避免習知技術中之封裝結構之製法具有較繁雜之步驟而導致產能低落、及浪費過多基板的有效面積而導致整體成本上升等問題,實已成為目前亟欲解決的課題。
鑑於上述習知技術之種種缺失,本發明之主要目的係提供一種能提高整體產能與降低整體成本之封裝結構之製法。
為達上述及其他目的,本發明揭露一種封裝結構之製法,係包括:提供一上下成對的整版面封裝基板,其相對的兩最外層表面上均形成複數打線墊與絕緣保護層,且該絕緣保護層中形成複數開孔,以令該等打線墊對應露出於各該開孔;分離該上下成對的整版面封裝基板,並裁切該整版面封裝基板,以成為複數封裝基板區塊,而各該封裝基板區塊具有相對之第一表面與第二表面,於該第一表面具有該等打線墊與絕緣保護層,而該第二表面具有複數電性接觸墊與介電層,且該等電性接觸墊嵌設並外露於該介電層表面,又各該封裝基板區塊具有呈(m×n)陣列排列的封裝基板單元,其中,m與n皆為大於1之整數;於該等電性接觸墊及介電層上設置第二承載板;於各該封裝基板單元之絕緣保護層上接置半導體晶片,以成為具有複數封裝結構單元的封裝結構區塊,而該半導體晶片具有相對之作用面與非作用面,該作用面上具有複數電極墊,而該非作用面固設於該絕緣保護層上,且各該電極墊藉由焊線以對應電性連接至各該打線墊;於該絕緣保護層、該等焊線及該等半導體晶片上形成封裝材;移除該第二承載板;以及裁切該封裝結構區塊以分離成複數封裝結構單元。
依上所述之封裝結構之製法,該上下成對的整版面封裝基板之製程係可包括:提供一具有相對兩表面之第一承載板;於該第一承載板之兩表面上均形成面積小於該第一承載板之剝離層;於該第一承載板未形成該剝離層之表面形成黏著層,以令該黏著層環繞該剝離層四周;於該剝離層與黏著層上形成金屬層;於該金屬層上依序形成複數電性接觸墊與增層結構,該增層結構係包括至少一介電層、形成於該介電層上之線路層、及複數形成於該介電層中並電性連接該線路層與電性接觸墊之導電盲孔,且該增層結構最外層之線路層復具有該等打線墊;以及於該增層結構最外層上形成該絕緣保護層,且該絕緣保護層中形成該等開孔,以令該等打線墊對應露出於各該開孔。或者,該上下成對的整版面封裝基板之製程係包括:提供一具有相對兩表面之第一承載板;於該第一承載板之兩表面上均形成黏著層;於該黏著層上全面貼設有面積小於該第一承載板且四周為該黏著層環繞之剝離層;於該剝離層與黏著層上形成金屬層;於該金屬層上依序形成複數電性接觸墊與增層結構,該增層結構係包括至少一介電層、形成於該介電層上之線路層、及複數形成於該介電層中並電性連接該線路層與電性接觸墊之導電盲孔,且該增層結構最外層之線路層復具有該等打線墊;以及於該增層結構最外層上形成該絕緣保護層,且該絕緣保護層中形成該等開孔,以令該等打線墊對應露出於各該開孔。
又於上述之製法中,該等封裝基板區塊之製程係可包括:沿該上下成對之整版面封裝基板的邊緣進行裁切,且裁切邊通過該剝離層;移除該第一承載板與剝離層以將該上下成對的整版面封裝基板分離成獨立的兩個整版面封裝基板;以及裁切該整版面封裝基板,並移除該金屬層,以成為該等封裝基板區塊。
前述之封裝結構之製法中,復可包括於該等打線墊上形成表面處理層,該表面處理層之材料可為鎳/金(Ni/Au)、化鎳鈀浸金(Electroless Nickel/Electroless Palladium/Immersion Gold,ENEPIG)、錫(Sn)、銀(Ag)、或金(Au)。
依上所述之製法,於移除該第二承載板之後,復可包括於各該電性接觸墊上形成焊球。
