Description
本發明係關於一種耐熱離型片及使用其之熱壓著方法。
使用NCF(Non-Conductive Film,非導電膜)及NCP(Non-Conductive Paste,非導電膏)等底部填充膠之半導體晶片之製造及覆晶封裝、以及印刷電路基板(PCB)之製造採用熱壓著之方法。熱壓著之方法亦用於使用各向異性導電膜(ACF)之PCB與電子零件之連接等。壓著對象物之熱壓著一般使用作為熱源及壓力源之熱加壓頭。為了防止熱壓著時之壓著對象物與熱加壓頭之固著,通常於壓著對象物與熱加壓頭之間配置耐熱離型片。
專利文獻1中雖未揭示耐熱離型片,但揭示了一種於纖維強化預浸體之曲面成形時所使用之四氟乙烯-六氟丙烯共聚物(FEP)膜。

[發明所欲解決之問題]
預想壓著對象物之熱壓著時之熱壓著溫度之進一步上升。藉由熱壓著溫度之進一步上升,例如,可進行積層有較先前更多之層之壓著對象物之熱壓著,可提高半導體晶片之製造效率及封裝效率。
本發明之目的在於提供一種耐熱離型片,其係於利用熱加壓頭所進行之壓著對象物之熱壓著時配置於壓著對象物與熱加壓頭之間,用以防止壓著對象物與熱加壓頭之固著者,其針對預想之熱壓著溫度之進一步上升,可更確實地應對。
[解決問題之技術手段]
本發明提供一種耐熱離型片,
其係於利用熱加壓頭所進行之壓著對象物之熱壓著時配置於上述壓著對象物與上述熱加壓頭之間,用以防止上述壓著對象物與上述熱加壓頭之固著者,
300℃下之表面硬度利用由式:A300
(%)=(d300
/t0
)×100所賦予之壓入度A300
表示,為15%以下。
其中,t0
係常溫(20℃)下之上述耐熱離型片之厚度。d300
係藉由基於以下之測定條件之熱機械分析(以下,記為「TMA」)而評價之300℃下之針入探針對上述耐熱離型片之壓入量。
[測定條件]
・測定模式:針入模式、升溫測定
・針入探針之形狀及前端直徑:圓柱狀及1 mmϕ
・施加壓力:1 MPa
・升溫起始溫度及升溫速度:20℃及10℃/分鐘
根據另一態樣,本發明提供一種熱壓著方法,
其係利用熱加壓頭所進行之壓著對象物之熱壓著方法,
於將耐熱離型片配置於上述熱加壓頭與上述壓著對象物之間之狀態下,藉由上述熱加壓頭對上述壓著對象物進行熱壓著,
上述耐熱離型片係上述本發明之耐熱離型片。
[發明之效果]
於本發明之耐熱離型片中,300℃下之表面硬度處於特定之範圍。因此,於使熱壓著溫度進一步上升之情形時,例如,即便於使熱加壓頭之加熱設定溫度上升至330℃左右之情況下,亦不易發生耐熱離型片對熱加壓頭之表面之接合,可保持作為耐熱離型片之較高之離型性。又,即便於藉由搬送而供給之耐熱離型片與熱加壓頭之間局部地發生接合之情形時,亦可抑制表面之延伸所導致之耐熱離型片對熱加壓頭之追隨,可確保較高之離型性。因此,根據本發明之耐熱離型片,針對預想之熱壓著溫度之進一步上升,可更確實地應對。
以下,一面參照圖式,一面對本發明之實施形態進行說明。

耐熱離型片1之300℃下之表面硬度利用由式:A300
(%)=(d300
/t0
)×100所賦予之壓入度A300
表示,為15%以下。此處,t0
係常溫(20℃)下之耐熱離型片1之厚度。d300
係藉由基於以下之測定條件之TMA而評價之300℃下之針入探針對耐熱離型片1之壓入量。
[測定條件]
・測定模式:針入模式、升溫測定
・針入探針之形狀及前端直徑:圓柱狀及1 mmϕ
・施加壓力:1 MPa
・升溫起始溫度及升溫速度:20℃及10℃/分鐘
壓入度A300
可為14.5%以下、14%以下、13.5%以下、13%以下、12.5%以下、12%以下、11.5%以下、11%以下、10.5%以下、10%以下、9.5%以下、9%以下、8.5%以下、8%以下、7.5%以下、7%以下、6.5%以下、5%以下、4.5%以下,進而可為4%以下。壓入度A300
之下限例如為-5%以上,亦可為-4%以上、-3%以上、-2%以上,進而亦可為-1%以上。再者,存在因耐熱離型片1之熱膨脹而導致壓入度A300
採取負值之情況。
圖1之耐熱離型片1包含PTFE片材2。但是,只要300℃下之表面硬度用壓入度A300
表示,為15%以下,則本發明之耐熱離型片1中所包含之樹脂並不限定於PTFE。考慮耐熱離型片1之耐熱性,耐熱離型片1中所包含之樹脂較佳為具有310℃以上之熔點及/或210℃以上之玻璃轉移溫度。熔點可為超過310℃、315℃以上、320℃以上,進而可為325℃以上。熔點之上限例如為400℃以下。玻璃轉移溫度可為220℃以上、230℃以上、240℃以上,進而可為250℃以上。玻璃轉移溫度例如為300℃以下。再者,本說明書中之「樹脂之熔點」意指於示差掃描熱量測定(以下,記為「DSC」)中以一定之升溫速度、例如10℃/分鐘將樹脂升溫之情形時所測定之「基於結晶熔解之吸熱峰」之峰溫度。又,本說明書中之「樹脂之玻璃轉移溫度」意指於DSC中以一定之升溫速度、例如10℃/分鐘將樹脂升溫之情形時所測定之「基於玻璃轉移之吸熱峰」之峰溫度。
本發明之耐熱離型片1中可包含之樹脂例如為選自PTFE、改性PTFE、聚醯亞胺、聚醯胺醯亞胺及聚醚醚酮(PEEK)之至少1種,可為選自PTFE、改性PTFE、聚醯胺醯亞胺及PEEK之至少1種,亦可為PTFE及/或改性PTFE。耐熱離型片1可包含PTFE片材、改性PTFE片材、聚醯亞胺片材、聚醯胺醯亞胺片材或PEEK片材,亦可包含PTFE片材、改性PTFE片材、聚醯胺醯亞胺片材或PEEK片材,亦可包含PTFE片材或改性PTFE片材。
改性PTFE係TFE與改性共聚單體之共聚物。為了分類為改性PTFE,共聚物中之四氟乙烯(TFE)單元之含有率需要為99質量%以上。改性PTFE例如為TFE與選自乙烯、全氟烷基乙烯基醚及六氟丙烯之至少1種改性共聚單體之共聚物。
亦可對耐熱離型片1中之至少一個主面(主面3A及/或主面3B)實施提高該主面中之上述表面硬度之改質處理,換言之,降低壓入度A300
之改質處理。於實施了該改質處理之耐熱離型片1中,針對熱壓著溫度之進一步上升,可進而確實地應對。改質處理較佳為不會針對上述至少一個主面形成包含與耐熱離型片中所包含者不同之樹脂及/或化合物之新的層及/或被膜的處理。該處理之例係將上述至少一個主面改性之處理。根據該處理,例如,可保持作為耐熱離型片1之熱傳導性。又,可防止所形成之新的層及/或被膜因熱壓著時之高溫而分解並產生之分解物所導致之熱加壓頭及/或壓著對象物之污染。
於利用熱加壓頭所進行之熱壓著中,耐熱離型片1中之與熱加壓頭相接之主面相比於與壓著對象物相接之主面,暴露於更高之溫度。因此,對一主面實施了上述改質處理之耐熱離型片1較佳為以該一主面與熱加壓頭相接之方式使用。
於耐熱離型片1包含PTFE片材或改性PTFE片材之情形時,改質處理例如為對上述一主面之化學處理。化學處理之例為金屬鈉處理。但是,改質處理並不限定於該例。於對PTFE片材及改性PTFE片材之金屬鈉處理中,推定於該片材之處理面進行氟原子之奪去及碳化(carbonization),藉此,處理面之表面硬度提高。金屬鈉處理例如可對作為處理對象之PTFE片材或改性PTFE片材中之上述至少一主面塗佈包含金屬鈉之處理液,或將作為處理對象之PTFE片材或改性PTFE片材浸漬於該處理液而實施。再者,根據浸漬之方法,亦可對PTFE片材或改性PTFE片材之兩個主面實施改質處理。
用於金屬鈉處理之處理液例如為金屬鈉之氨溶液、金屬鈉-萘錯合物之四氫呋喃溶液。作為處理液,亦可使用市售之處理液(例如,TECHNOS製造之Fluorobonder(註冊商標))。
再者,已知,藉由對PTFE片材之金屬鈉處理而使處理面之被接著性提高。於用作耐熱離型片之情形時、尤其於使熱壓著溫度進一步上升時可提高離型性之作用被本發明人等首次發現。
PTFE片材2較佳為包含經煅燒之PTFE之煅燒PTFE片材。再者,於本說明書中,PTFE之煅燒意指將藉由聚合而獲得之PTFE加熱至其熔點(327℃)以上之溫度,例如340~380℃。
耐熱離型片1之厚度例如為1~50 μm,亦可為5~40 μm、10~35 μm、20~35 μm,進而亦可為25~35 μm。
耐熱離型片1之拉伸強度根據耐熱離型片1中所包含之樹脂之種類而不同,例如為30 MPa以上,亦可為33 MPa以上、35 MPa以上、40 MPa以上、45 MPa以上、50 MPa以上、55 MPa以上、60 MPa以上、80 MPa以上、100 MPa以上、150 MPa以上、200 MPa以上、220 MPa以上、240 MPa以上,進而亦可為260 MPa以上。拉伸強度之上限例如為500 MPa以下。根據具有該等範圍之拉伸強度之耐熱離型片1,可更確實且穩定地實施利用向熱加壓頭與壓著對象物之間之搬送所進行之供給。
耐熱離型片1之最大拉伸伸長率亦根據耐熱離型片1中所包含之樹脂之種類而不同,例如為380%以下,亦可為360%以下、340%以下、300%以下、280%以下、250%以下、200%以下、180%以下、150%以下、130%以下、120%以下、100%以下、50%以下、40%以下,進而亦可為35%以下。最大拉伸伸長率之下限例如為5%以上。根據具有該等範圍之最大拉伸伸長率之耐熱離型片1、尤其具有300%以下之最大拉伸伸長率之耐熱離型片1,在向熱加壓頭與壓著對象物之間搬送之耐熱離型片1之供給時,於熱加壓頭及/或壓著對象物與耐熱離型片1之間部分地發生接合時,亦可抑制片材1根據伸長率而追隨該等構件。換言之,可進一步提高對熱加壓頭及/或壓著對象物之耐熱離型片1之離型性。
耐熱離型片1之拉伸強度及最大拉伸伸長率可藉由使用拉伸試驗機之拉伸試驗而求出。拉伸試驗中之拉伸方向例如為耐熱離型片1之長度方向(MD(Machine direction,機械)方向)。試片之形狀例如為日本工業規格(JIS)K6251:1993中所規定之啞鈴1號形。使用上述試片之情形之測定條件例如為試片之標線間距離40 mm、夾頭間距離70 mm及拉伸速度200 mm/min。最大拉伸伸長率可由試驗前之上述標線間距離、及斷裂時之標線間距離算出。測定溫度例如為25±10℃。
於耐熱離型片1中,亦可於主面3A及/或主面3B上配置其他層。然而,為了確保作為耐熱離型片1之良好之熱傳導性,較佳為不於耐熱離型片1之主面上配置其他層。換言之,耐熱離型片1較佳為單層。
耐熱離型片1較佳為非多孔質片材。耐熱離型片1亦可基於片材1中所包含之材料、例如PTFE所具有之較高之撥液性(撥水性及撥油性)而為不使水等流體(fluid)於厚度方向上透過之不透性片材。又,耐熱離型片1還可基於該片材1中所包含之材料、例如PTFE所具有之較高之絕緣性而為絕緣性片材(非導電片材)。
耐熱離型片1之形狀例如為包含正方形及長方形之多邊形、圓形、橢圓形、以及帶狀。多邊形之角亦可變圓。但是,耐熱離型片1之形狀並不限定於該等例。分別而言,多邊形、圓形及橢圓形之耐熱離型片1可實現作為單片之流通,帶狀之耐熱離型片1可實現作為捲繞為捲芯之捲繞體(捲筒)之流通。帶狀之耐熱離型片1之寬度、及捲繞帶狀之耐熱離型片1而成之捲繞體之寬度可自由地設定。
[耐熱離型片之製造方法]
以下,以包含PTFE片材2或改性PTFE片材之耐熱離型片1為例,對耐熱離型片1之製造方法之一例進行說明。但是,耐熱離型片1之製造方法並不限定於以下所示之例。
首先,將PTFE粉末(成型粉末)導入至模具中,並對模具內之粉末以特定時間施加特定壓力而預成形。預成形可於常溫下實施。為了實現下述利用切削車床之切削,模具之內部空間之形狀較佳為圓柱狀。於此情形時,可獲得圓柱狀之預成形品及PTFE塊體。其次,自模具取出所獲得之預成形品,於PTFE之熔點(327℃)以上之溫度煅燒特定之時間,而獲得PTFE塊體。其次,藉由將所獲得之PTFE塊體切削為特定之厚度,而獲得作為切削片材(削薄片材)之PTFE片材2。所獲得之PTFE片材2可直接用作耐熱離型片1,亦可經特定之處理或其他層之積層等後用作耐熱離型片1。處理之例係提高上述表面硬度之改質處理。改質處理之例係金屬鈉處理。為了提高耐熱離型片1之拉伸強度,或抑制最大拉伸伸長率,亦可將PTFE片材2延伸及/或壓延。於PTFE塊體為圓柱狀之情形時,可利用一面使塊體旋轉,一面連續地切削表面之切削車床,而可有效率地形成PTFE片材2及耐熱離型片1。又,根據切削車床,所形成之PTFE片材2及耐熱離型片1之厚度之控制相對較容易,亦可形成帶狀之PTFE片材2及耐熱離型片1。又,藉由使用改性PTFE粉末代替PTFE粉末,可利用上述方法形成改性PTFE片材。
耐熱離型片1亦可藉由以下之方法而製造。
首先,準備將PTFE分散液塗佈於表面之基材片材。基材片材例如包含樹脂、金屬、紙及其等之複合材料。亦可對基材片材中之要塗佈PTFE分散液之表面實施用以使自基材片材之PTFE片材2之剝離變得容易之剝離處理。剝離處理可應用公知之方法。其次,於基材片材之表面形成PTFE分散液之塗佈膜。PTFE分散液之塗佈可使用公知之各種塗佈機。亦可藉由將基材片材浸漬於PTFE分散液而於基材片材之表面塗佈PTFE分散液。其次,藉由乾燥及煅燒,而由形成於基材片材之表面之PTFE分散液之塗佈膜形成PTFE片材。其次,將所形成之PTFE片材自基材片材剝離,而獲得作為流延片材之PTFE片材2。所獲得之PTFE片材2可直接用作耐熱離型片1,亦可經特定之處理或其他層之積層等後用作耐熱離型片1。處理之例如上所述。為了提高耐熱離型片1之拉伸強度,或抑制最大拉伸伸長率,亦可將PTTFE片材2延伸及/或壓延。於該方法中,可根據對基材片材之PTFE分散液之塗佈厚度及/或塗佈次數,而控制所形成之PTFE片材2及耐熱離型片1之厚度。又,藉由使用改性PTFE分散液代替PTFE分散液,可利用上述方法形成改性PTFE片材。
[耐熱離型片之使用]
如圖2所示,耐熱離型片1可用作在利用熱加壓頭21所進行之壓著對象物22之熱壓著時配置於熱加壓頭21與壓著對象物22之間且防止兩者之固著的耐熱離型片。耐熱離型片1之離型性優異。根據耐熱離型片1,可防止由熱壓著時之熱所導致之對熱加壓頭21及/或壓著對象物22之該片材1之固著(熱固著)。
耐熱離型片1亦可藉由搬送而供給及配置於熱加壓頭21與壓著對象物22之間。藉由搬送而供給及配置之耐熱離型片1例如為帶狀。
壓著對象物22例如為半導體晶片、PCB、電子零件。耐熱離型片1例如可用於利用熱壓著之半導體晶片之製造及覆晶封裝、PCB之製造、以及電子零件之連接等。
熱壓著時之熱加壓頭21之加熱設定溫度,換言之,耐熱離型片1之使用溫度例如可設為300℃以上。使用溫度可為310℃以上、320℃以上、330℃以上,進而可為340℃以上。但是,耐熱離型片1之使用溫度並不限定於該等範圍。亦可使用低於上述例示之使用溫度下之耐熱離型片1。
[熱壓著方法]
可使用本發明之耐熱離型片1對壓著對象物22進行熱壓著。該熱壓著方法係利用熱加壓頭21所進行之壓著對象物22之熱壓著方法,於將耐熱離型片1配置於熱加壓頭21與壓著對象物22之間之狀態下,藉由熱加壓頭21對壓著對象物22進行熱壓著。耐熱離型片1例如可藉由搬送而供給及配置於熱加壓頭21與壓著對象物22之間。
[熱壓著物之製造方法]
可使用本發明之耐熱離型片1製造熱壓著物。該熱壓著物之製造方法包含如下步驟:於將耐熱離型片1配置於熱加壓頭21與壓著對象物22之間之狀態下,實施使用熱加壓頭21之壓著對象物22之熱壓著,而獲得壓著對象物22之熱壓著體即熱壓著物。熱壓著物之例係PCB及電子零件。

[拉伸強度及最大拉伸伸長率]
