Description

積層體及積層體之製造方法
本發明係關於一種積層體及積層體之製造方法，具體而言，係關於一種於半導體封裝之製造步驟中用於支持加工基板之支持玻璃基板。
於晶圓級封裝體(WLP，Wafer Level Package)中，提出有扇出(fan-out)型WLP。已知於扇出型WLP中，為了抑制加工基板之尺寸變化，使用支持加工基板之玻璃基板(專利文獻1)。
然而，於WLP之製造步驟中，如圖1所示，具有：於支持玻璃101積層剝離層102之步驟、於剝離層102設置半導體晶片103後用樹脂104進行密封而製成樹脂模製物之步驟等高溫條件之步驟。有因於該等步驟中產生之熱，而於支持玻璃101、剝離層102、半導體晶片103及樹脂104之積層體產生翹曲之情況。並且，有於支持玻璃101與包含剝離層102、半導體晶片103及樹脂104之加工基板之分離後亦於加工基板直接產生翹曲之情況。
作為翹曲之改善對策，研究出藉由使用翹曲更小之支持玻璃基板加以改善，但並未進行以藉由使支持玻璃基板預先朝與WLP之製造步驟中產生之翹曲相反之方向翹曲而抵消WLP之製造步驟中產生之翹曲為目的之研究。
又，已知藉由於玻璃基板被覆薄膜而產生翹曲(專利文獻2)，但對於使玻璃板以更薄之薄膜有效率地產生翹曲之技術未作研究。
先前技術文獻 專利文獻
專利文獻1：日本特開2017-30997號公報
專利文獻2：國際公開第2017/204167號
雖然藉由使被覆層變厚而增大積層體之翹曲較為容易，但由於扇出型WLP之製造步驟中加工基板與支持基板之分離可藉由對剝離層進行可見光波長之雷射照射而實現，故而會因被覆層之材質或被覆層之厚度而阻礙雷射之透過，故而成為問題。
於此種狀況下，期待一種維持可見光透過性並且具有較大之翹曲之支持玻璃基板材料。
本發明者發現，藉由具有特定之翹曲與構成之積層體及基於特定條件之積層體之製造方法，可解決上述問題。
即，本發明提供一種積層體，其係具有玻璃板及被覆層者，且上述被覆層含有選自由氮化矽、氧化鈦、氧化鋁、氧化鈮、氧化鋯、銦錫氧化物、氧化矽、氟化鎂及氟化鈣所組成之群中之1種以上之成分，被覆層之厚度dc相對於玻璃板之厚度dg之比為 dc/dg=0.05×10-3 ～1.2×10-3 之範圍， 上述積層體於自重撓曲修正條件下之曲率半徑r1為10 m～150 m。
藉由本發明，可提供一種維護可見光透過性並且具有較大之翹曲之積層體。進而，藉由使用該積層體作為支持玻璃基板，可實現尺寸精度較高之WLP之製造。
對本發明之積層體及積層體之製造方法進行說明。再者，於本說明書中，表示數值範圍之波浪符號「～」只要無特別說明，則表示包含其前後所記載之數值作為下限值及上限值。
[玻璃組成] 本發明之積層體中所使用之玻璃板之組成並無特別限定，可使用可見光透過率較高之公知之組成。具體而言，可使用波長400 nm～1000 nm下之透過率之最低值(T%)為60%以上者。
作為較佳之組成，可列舉： 以氧化物基準之質量%表示為 SiO2 ：40%～70%、 B2 O3 ：0%～15%、 MgO：0%～10%、 CaO：0%～10%、 SrO：0%～13%、 BaO：0%～40%、 Na2 O：0%～30%、 K2 O：0%～13%、 Al2 O3 ：0.5%～15% 之範圍之組成。
作為尤佳之組成，可列舉： 以氧化物基準之質量%表示為 SiO2 ：49%～70%、 B2 O3 ：4%～13%、 MgO：0%～0.5%、 CaO：0%～8%、 SrO：0%～8%、 BaO：0%～13%、 Na2 O：4%～15%、 K2 O：0.1%～13%、 Al2 O3 ：4%～13% 之範圍之組成。
若組成為該範圍，則可見光透過率優異。又，關於高熱膨脹係數之玻璃組成，因熱處理造成之翹曲之影響增大，故而本發明之效果尤其大。
[玻璃板] 玻璃板可用於本發明之積層體。玻璃板係藉由將上述玻璃組成成形為特定之形狀(例如，四邊形或圓盤狀)之板而製造。
玻璃板之成形方法並無限定，可使用例如浮式法、熔融法及滾壓法等公知之方法。又，於本發明中，為了使積層體大幅地翹曲，較佳為使被覆前之玻璃板具有一定之翹曲。
關於較佳之被覆前之玻璃板之翹曲，玻璃板於自重撓曲修正條件(對玻璃晶圓本來具有之翹曲量進行修正所得之值；於重力下會產生因自重所引起之'撓曲'，但為去除其所得之值)下之曲率半徑r0較佳為200 m～500 m，進而較佳為300 m～400 m。藉由使被覆前之玻璃板之翹曲為該範圍，下述藉由被覆所獲得之積層體之翹曲增大。
處於此種條件之玻璃板係藉由例如自利用浮式法所製造之素板將具有該範圍之翹曲之部分切出而容易地獲得。
玻璃板之板厚(dg)較佳為0.3 mm～3.0 mm。進而較佳為0.5 mm～2.0 mm，尤佳為0.7 mm～1.2～ mm。藉由為該範圍，作為積層體之強度優異，重量亦成為容許範圍。又，玻璃板亦可使用經化學強化者。
[被覆層] 於本發明中，藉由於上述玻璃板被覆薄膜，而形成被覆層。被覆層含有選自由氮化矽、氧化鈦、氧化鋁、氧化鈮、氧化鋯、銦錫氧化物、氧化矽、氟化鎂及氟化鈣所組成之群中之1種以上之成分。氮化矽及氧化鈦之可見光透過性及使積層體翹曲之效果優異，故而較佳。
作為被覆方法，可使用濺鍍法、離子輔助蒸鍍法及霧劑沈積法等公知之方法。其中，濺鍍法使積層體翹曲之效果優異，故而較佳。並且，被覆係藉由對具有上述翹曲之玻璃板之凸面側進行，而增大玻璃板之翹曲。
被覆層(dc)之厚度較佳為0.05μm~1.2μm。進而較佳為0.1μm~1.0μm，尤佳為0.4μm~0.6μm。藉由為該範圍，可兼顧積層體之翹曲之大小與可見光透過性之高度。
[積層體]
本發明之積層體具有上述玻璃板及上述被覆層。又，自重撓曲修正條件下之曲率半徑r1為10m~150m，較佳為30m~100m之範圍。藉由為該範圍，可製造尺寸精度較高之WLP。
又，被覆層之厚度dc相對於玻璃板之厚度dg之比為dc/dg=0.05×10-3~1.2×10-3，較佳為0.4×10-3~0.5×10-3之範圍。藉由為該範圍，可兼顧積層體之翹曲之大小與可見光透過性之高度。
積層體之厚度較佳為0.3mm~3.5mm。更佳為0.5mm~2.5mm，尤佳為0.7mm~1.3mm。藉由為該範圍，可兼顧積層體之強度與可見光透過性之高度。
又，積層體之形狀較佳為四邊形或圓盤狀。
該積層體可適當地用作支持玻璃基板。
[積層體之製造方法]
本發明之積層體係藉由於上述玻璃板進行上述被覆而製造。作為較佳之製造方法之具體例，為具有如下步驟之條件，即，如圖2所示，於具有自重撓曲修正條件下之曲率半徑200m~500m之翹曲之玻璃板11之凸側，進行含有選自由氮化矽、氧化鈦、氧化鋁、氧化鈮、氧化鋯、銦錫氧化物、氧化矽、氟化鎂及氟化鈣所組成之群中之1種以上之成分的薄膜(被覆層)12之被覆。藉由於該條件下進行製造，可適當地獲得積層體10於自重撓曲修正條件下之曲率半徑r1為10 m～150 m以下之積層體10。
於所獲得之積層體10之剝離層12設置半導體晶片13後，藉由以樹脂14將半導體晶片13密封，而獲得樹脂模製物。即便將積層體10之剝離層12上之半導體晶片13及樹脂14分離，亦可抑制包含半導體晶片13及樹脂14之加工基板產生翹曲。 [實施例]
以下，藉由實施例及比較例更具體地說明本發明，但只要發揮本發明之效果，則可適當變更實施形態。
＜評價用樣品形狀＞ 使用對直徑150 mm(6英吋)、板厚1.0 mm之圓盤狀之玻璃板於表1中記載之條件下進行被覆而成者。
＜測定條件、評價條件＞ [玻璃板之厚度(dg)及被覆層之厚度(dc)之測定] 於室溫條件下使用雷射位移計(神津精機公司製造之Dyvoce)，測定被覆前之玻璃板及被覆後之積層體之厚度，求出dg及dc。
[玻璃板及積層體之曲率半徑(r0、r1)] 對於樣品，使用雷射位移計(神津精機公司製造之Dyvoce)，藉由根據雙面差量模式之自重撓曲修正求出樣品本來具有之翹曲量，並以此為基準藉由形狀模擬而算出。然後，由利用模擬所獲得之形狀而求出曲率半徑。
將被覆前之玻璃板於自重撓曲修正條件下之曲率半徑設為r0，將被覆後之積層體之玻璃板於自重撓曲修正條件下之曲率半徑設為r1。
[翹曲之評價] 通常被覆層越厚，則藉由被覆所產生之翹曲越大。因此，翹曲之評價係關於下述式所示之R進行。評價A～D中，將A、B及C設為合格。 式：R=r1(m)×dc(μm) 評價： A：R≦30、 B：30＜R≦50、 C：50＜R＜70、 D：70≦R
[可見光透過性] 對於樣品，於室溫條件下使用分光透過率測定機(日本分光公司製造之V-700)，測定波長400-1000 nm下之透過率之最低值(T%)。評價A～C中，將A或B設為合格。 評價： A：80%≦T、 B：60%≦T＜80%、 C：T＜60%
[實施例1] 藉由浮式法而獲得組成1(以質量%計，SiO2 ：56.9%、Al2 O3 ：8.1%、CaO：2.3%、SrO：12.3%、BaO：20.4%)之玻璃之素板(縱橫1000 mm、厚度1.4 mm)。自上述素板之中心部裁切出半徑75 mm(直徑：150 mm)之圓形作為圓盤狀玻璃板。於進行倒角加工後，利用雙面研磨機(浜井製作所公司製造之16B-N/F)進行研磨而將板厚(dg)調整為1.0 mm。該玻璃板之曲率半徑r0(源自浮式法)於自重撓曲修正條件下為370 m。
其後，於濺鍍裝置(ULVAC公司製造之SIV-345XYSSS)中使用矽靶，藉由反應性濺鍍，於玻璃板之翹曲之凸面側以膜之壓縮應力成為1 GPa之方式形成氮化矽膜。被覆層之厚度(dc)為0.5 μm。將評價結果示於表1。
[實施例2～實施例7及比較例1～4] 變更為表1中記載之條件，除此以外，與實施例1同樣地進行操作。將評價結果示於表1。
