Description

具有熱管理之堆疊矽封裝組件
本新型之具體實例大體上關於一種晶片封裝組件,且詳言之,關於一種包含至少安置在封裝基板或內插件上之積體電路(integrated circuit;IC)晶粒及複數個附加晶粒熱傳遞柱的晶片封裝組件。
諸如平板電腦、電腦、影印機、數位攝影機、智慧型電話、控制系統及自動化櫃員機等之電子裝置經常採用充分利用晶片封裝組件之能力的電子組件,以用於提高的功能性及較高的組件密度。習知的晶片封裝方案經常利用封裝基板,經常結合矽穿孔(through-silicon-via;TSV)內插件,以使得複數個積體電路(IC)晶粒能夠安裝至單一封裝基板。IC晶粒可包含記憶體、邏輯或其他IC裝置。
在許多晶片封裝組件中,提供充足熱管理變得越來越具有挑戰性。未能提供充足冷卻經常使得使用壽命減少並且甚至引起裝置故障。熱管理尤其在高頻寬記憶體(high band-width memory;HBM)及諸如場可程式化閘陣列(field programmable gate array;FPGA)之邏輯晶粒整合於單一封裝組件中之應用中是成問題的。在此類應用中,記憶體及邏輯晶粒可在極接近熱接面溫度限制之溫度下操作。因此,諸如因空調機故障產生之環境溫度的小波動可能會快速地導致超過熱接面溫度限制,從而引起裝置故障或系統停機。
因此,需要一種具有經改良的熱管理之晶片封裝組件。
本文中記載一種晶片封裝組件及其製造方法,其利用複數個附加晶粒熱傳遞柱以用於改良熱管理。在一個實例中,提供一種晶片封裝組件,其包括:一第一積體電路(IC)晶粒,其安裝至一基板;一罩蓋,其安置於該第一IC晶粒上方;及複數個附加晶粒傳導柱,其安置於該罩蓋與基板之間。該等附加晶粒傳導柱在該罩蓋與基板之間提供在該第一IC晶粒外部橫向延伸之熱傳遞路徑。
在另一實例中,提供一種晶片封裝組件,其包括一基板、安裝至該基板之至少一第一記憶體晶粒、安裝並通信耦接至該基板之至少一第一邏輯晶粒、安置於該第一記憶體晶粒及該第一邏輯晶粒上方之一罩蓋、安置於該第一記憶體晶粒及該第一邏輯晶粒周圍之一介電材料,及一第一傳導柱。該介電材料安置於該基板與該罩蓋之間。該第一傳導柱安置於穿過該介電材料形成之一孔中,並且在該罩蓋與基板之間提供一熱傳遞路徑。
在又另一實例中,提供一種用於製造一晶片封裝組件之方法。該方法包括將一第一積體電路(IC)晶粒安裝至一基板、在該基板上之該第一IC晶粒外部形成附加晶粒導熱柱,及在該第一IC晶粒及該等附加晶粒傳導柱上方安裝一罩蓋。
在另一實例中,該用於製造一晶片封裝組件之方法亦可包括在安置於該第一IC晶粒周圍之一介電材料中形成一孔,及當形成該等附加晶粒導熱柱時用一塊狀導熱層填充該孔。
在另一實例中,該用於製造一晶片封裝組件之方法亦可包括將該等附加晶粒傳導柱沈積在該基板上,及當形成該等附加晶粒導熱柱時在該等附加晶粒傳導柱及該第一IC晶粒周圍沈積一塊狀導熱層。
提供一種晶片封裝組件及其製造方法,其利用安置於積體電路(IC)晶粒周圍之複數個附加晶粒熱傳遞柱。本文中所描述之晶片封裝組件包括安置在基板上之至少一個積體電路(IC)晶粒及罩蓋。該基板可為封裝基板或內插件。形容詞「附加晶粒」描述該等柱不延伸通過IC晶粒並且在IC晶粒外部橫向延伸。附加晶粒熱傳遞柱在罩蓋與基板之間提供穩健的熱傳遞路徑。儘管本文中提供之實例說明安置於罩蓋與呈內插件形式之基板之間的附加晶粒熱傳遞柱,但附加晶粒熱傳遞柱可在不利用內插件之具體實例中替代地安置於罩蓋與呈封裝基板形式之基板之間。有利地,至晶片封裝組件之罩蓋的增強的熱傳遞會改良可靠性及效能。此外,附加晶粒熱傳遞柱可經配置以例如藉由在一個區上使用比在另一區上還多之柱來增強橫越整個晶片封裝組件之熱傳遞,從而縮減可能誘發翹曲或提供IC晶粒之不充分溫度控制的熱點。另外,附加晶粒熱傳遞柱自內插件移除熱量之能力顯著地縮減晶片封裝組件內之熱耦合及溫度上升,從而有利地提高電遷移(electromigration;EM)壽命。
現在轉而參看圖1,示意性地說明具有安置於積體電路(IC)晶粒106周圍之複數個附加晶粒熱傳遞柱110的晶片封裝組件100之示意性截面視圖。晶片封裝組件100亦包括罩蓋102、內插件104及封裝基板108。
儘管圖1中展示兩個IC晶粒106,但IC晶粒之總數目可介於兩個至可裝配在晶片封裝組件100內之數量的範圍內。可用於晶片封裝組件100中之IC晶粒106之實例包括但不限於諸如場可程式化閘陣列(FPGA)之可程式化邏輯裝置、諸如高頻寬記憶體(HBM)之記憶體裝置、光學裝置、處理器或其他IC邏輯結構。IC晶粒106中之一或多者可視情況包括光學裝置,諸如光電偵測器、雷射器、光源等。
每一晶粒106包括底部表面140及頂部表面142。晶粒106之底部表面140藉由焊料連接118或其他適合的電氣連接以耦接至內插件104之頂部表面138。晶粒106之頂部表面142面朝罩蓋102之底部表面144。熱界面材料(thermal interface material;TIM)114安置於晶粒106之頂部表面142與罩蓋102之底部表面144之間以增強其間的熱傳遞。在一個實例中,TIM 114可為熱凝膠或熱環氧樹脂,諸如封裝組件連接黏著劑,其可購自位於新澤西普林斯頓樞紐(Princeton Junction, New Jersey)的AI Technology, Inc.。
在一些實施方式中,罩蓋102由硬質材料製成。在其他實施方式中,尤其在需要利用罩蓋102以自IC晶粒106及柱110接收熱量之實施方式中,罩蓋102由諸如不鏽鋼、銅、鍍鎳銅或鋁之導熱材料以及其他適合的材料製成。未展示之散熱片可視情況安裝至罩蓋102之頂部表面146。
罩蓋102可在結構上耦接至封裝基板108以增加晶片封裝組件100之硬度。視情況,加強件120可用以在結構上將罩蓋102耦接至封裝基板108。當使用時,加強件120可由陶瓷、金屬或其他各種無機材料製成,諸如氧化鋁(Al 2O 3)、氮化鋁(AlN)、氮化矽(SiN)、矽(Si)、銅(Cu)、鋁(AL)及不鏽鋼以及其他材料。加強件120亦可由有機材料製成,諸如覆銅層合物。
如上文所論述,IC晶粒106藉由焊料連接118以連接至內插件104之電路。內插件104之電路類似地連接至封裝基板108之電路。在圖1中所描繪之實例中,內插件104之底部表面136藉由焊料連接118或其他適合連接以電氣方式且機械地耦接至封裝基板108之頂部表面134。
晶片封裝組件100可安裝至印刷電路板(printed circuit board;PCB)116以形成電子裝置150。以此方式,封裝基板108之電路經由焊球122或其他適合連接以耦接至封裝基板108之電路。在圖1中所描繪之實例中,封裝基板108之底部表面132藉由焊球122以電氣方式且機械地耦接至PCB之頂部表面130。
介電質填充物112安置在晶粒106之間的內插件104上。介電質填充物112向封裝組件100提供額外硬度,同時亦保護焊料連接118。介電質填充物112可為基於環氧樹脂之材料或其他適合的材料。介電質填充物112可另外包括填充物,例如無機填充物,諸如二氧化矽(SiO 2)。在一個實例中,介電質填充物112可具有在約20至約40 ppm/攝氏度之間的CTE、在約5至約20帕斯卡-秒之間的黏度,及在約6至約15帕斯卡(Pa)之間的楊氏模數。
在一個實例中,介電質填充物112在固化之前具有適合於流入並填充在晶粒106之底部表面140與內插件104之頂部表面138之間的圍繞焊料連接118之填隙空間的黏度。替代地,單獨的底填充材料可用於填充在晶粒106之底部表面140與內插件104之頂部表面138之間的圍繞焊料連接118之填隙空間,而介電質填充物112安置於底填充料上方並填充鄰近晶粒106之間的填隙空間。
附加晶粒熱傳遞柱110延伸通過介電質填充物112,並在內插件104之頂部表面138與罩蓋102之底部表面144之間提供穩健的傳導熱傳遞路徑。可在柱110與罩蓋102之間利用TIM以在柱110與罩蓋102之底部表面144之間提供穩健的熱傳遞界面。柱110通常由導熱材料形成,該導熱材料經選擇以在罩蓋102與內插件104之間提供良好的熱傳遞。柱110可具有任何合適的截面輪廓,且通常具有大約與晶粒106之高度相同的長度。在一個實例中,柱110之截面輪廓為圓形的。柱110之數量、大小、密度及位置可經選擇以在罩蓋102與內插件104之間提供所要的熱傳遞輪廓,例如用以對一個晶粒106比另一晶粒106產生更多熱量進行補償。
圖2為圖1之具有罩蓋102之晶片封裝組件100的示意性俯視圖,該罩蓋經移除以顯露安置於IC晶粒106周圍之附加晶粒熱傳遞柱110之例示性幾何配置。在圖2中所描繪之實例中,晶片封裝組件100經組態為高頻寬記憶體(high band-width memory;HBM)裝置,其中IC晶粒106 A經組態為場可程式化閘陣列(field programmable gate array;FPGA)且IC晶粒106 B經組態為HBM晶粒。預期包含晶片封裝組件100之IC晶粒可為相同或不同類型,其包括HBM及FPGA晶粒之外的類型。
在圖2中所描繪之實例中,附加晶粒熱傳遞柱110包括安置於鄰近晶粒106 A之間、安置於鄰近晶粒106 B之間及安置於鄰近晶粒106 A與106 B之間的柱202。另外,附加晶粒熱傳遞柱110包括安置於晶粒106 A、106 B與內插件104之邊緣208之間的柱204。換言之,柱204安置在晶粒106 A、106 B外部,且安置在加強件120之邊緣210內部。柱202、204之位置、大小及密度可經選擇以增強所要位置中之熱傳遞,並控制晶片封裝組件100之翹曲。下文進一步所描述之圖3至圖5中提供之例示用非限制性實例中所提供柱110之額外細節。
圖3為安置於內插件104之頂部表面138與罩蓋102之底部表面144之間的附加晶粒熱傳遞柱110之一個實例的示意性截面視圖。柱110安置於延伸通過介電質填充物112之孔302中。可在將柱110沈積在介電質填充物112中之前形成孔302。舉例而言,孔302可藉由蝕刻、雷射鑽孔、壓印、熱成形、機械鑽孔或其他適合方法來形成。可在柱110安置在內插件104上之後替代地形成孔302。舉例而言,介電質填充物112可圍繞先前形成的柱110來形成,諸如藉由在先前形成的柱110周圍模製填充物112或藉由其他適合技術。
在圖3中所描繪之具體實例中,柱110包括在內插件104與罩蓋102之間延伸的塊狀導體306。塊狀導體306可為填充或鍍覆在孔302內的金屬。在一個實例中,塊狀導體306為無電極鍍製銅或電鍍銅。塊狀導體306可形成在內插件104之頂部表面138的正上方。視情況,晶種層304可形成在內插件104之頂部表面138上,且塊狀導體306藉由鍍製以在晶種層304上形成。對於在孔302內之塊狀導體306的無電極鍍製不需要使用晶種層304。儘管未展示,但晶種層304可另外沿著孔302之側壁來形成。一旦塊狀導體306形成於孔302中,則TIM 114安置在塊狀導體306上以在柱110與罩蓋102之間提供良好的熱傳遞界面,以有利地改良晶片封裝組件100之熱傳遞效能。
圖4為安置於內插件104之頂部表面138與罩蓋102之底部表面144之間的附加晶粒熱傳遞柱400之另一實例的示意性截面視圖。附加晶粒柱400可用以替換用於晶片封裝組件100中之附加晶粒柱110中之任一個或全部。
類似於上文所描述的附加晶粒柱110,附加晶粒柱400安置於延伸通過介電質填充物112之孔302中。附加晶粒柱400可直接在內插件104之頂部表面138上安置於孔302中。視情況,TIM 114或其他導熱黏著劑或糊狀物可安置於柱400與內插件104之頂部表面138之間。
在圖4中所描繪之實例中,附加晶粒柱400呈經組態以在物件端部之間提供高熱傳遞速率的物件之形式。高熱傳遞速率的物件利用超導熱性質以在物件端部之間轉移熱量。高熱傳遞速率的物件可包括(1)振動並接觸物件內之顆粒以傳遞熱量,諸如工業金剛石,或(2)藉由提供兩個被動流動功能性(諸如熱管)來移動物件內之顆粒,或(3)藉由物件內之引入的流體循環而引起的強制流移動來移動顆粒,該引入的流體循環將自外部物件(即,封裝外部的泵)泵吸。在圖4中所描繪之實例中,高熱傳遞速率物件展示為熱管402。熱管402包括密封管404,其具有第一端部410及第二端部412。密封管404包括其中安置相變材料406的密封空腔408。在操作中,與導熱固體表面(亦即密封管404之第一端部410)接觸之液相的相變材料406藉由自內插件104吸收熱量而轉變成蒸汽。蒸汽接著在密封管404之密封空腔408內部之第一端部410與冷界面(亦即密封管404之第二端部412)之間行進,並且冷凝回液體—藉由TIM 114以將潛熱釋放至罩蓋102中。呈液體形式之相變材料406接著藉由毛細管作用及/或重力以返回至密封管404之第一端部410處之熱界面,且該循環重複進行。由於用於沸騰及冷凝之熱傳遞係數極高,因此附加晶粒柱400在內插件104之頂部表面138與罩蓋102之底部表面144之間有效且高效地傳導熱量,以有利地改良晶片封裝組件100之熱傳遞效能。
圖5為安置於內插件104之頂部表面138與罩蓋102之底部表面144之間的附加晶粒熱傳遞柱500之另一實例的示意性截面視圖。附加晶粒柱500可用以替換用於晶片封裝組件100中之附加晶粒柱110中之任一個或全部。
類似於上文所描述的附加晶粒柱110,附加晶粒柱500安置於延伸通過介電質填充物112之孔302中。附加晶粒柱500可直接在內插件104之頂部表面138上安置於孔302中。視情況,TIM或其他導熱黏著劑或糊狀物可安置於柱500與內插件104之頂部表面138之間。
在圖5中所描繪之實例中,附加晶粒柱500包括安置於孔302中之塊狀導體502。塊狀導體502包括導熱材料。導熱材料可為單一實心塊狀物,或包含多個元件,諸如粉末、金屬棉或離散形狀以及其他形式。導熱材料可為焊錫膏、金屬纖維、金屬粉末、金屬顆粒、金屬球、導熱黏著劑或其他適合的導熱材料。在一個實例中,塊狀導體502包含填充孔302之複數個銅球。在銅球(或填充孔302之其他傳導材料)之間的填隙空間可填充TIM或其他熱傳遞材料。
圖6為用於製造具有附加晶粒熱傳遞柱之晶片封裝組件(諸如上文參看圖1至圖5所描述的晶片封裝組件100等)之方法600的流程圖。圖7A至圖7J為晶片封裝組件在圖6之方法600的不同階段之示意性截面視圖。
方法600藉由將內插件104附接至載體700以在操作602處開始,如圖7A中所說明。僅在最初的製造操作期間利用載體700,並且因而,該載體以可移除方式被附接至內插件104之底部表面136。在一個實例中,使用可釋放壓敏黏著劑以將內插件104附接至載體700。
在操作604處,晶粒106附接至內插件104之頂部表面138,如圖7B中所說明。在晶粒附接操作期間,焊料連接118經回焊以將晶粒106之電路機械地並以電氣方式附接至內插件104之電路。
在操作606處,介電質填充物112安置於晶粒106及內插件104之頂部表面138上方,如圖7C中所說明。介電質填充物112可藉由另一合適方法進行旋塗、施配、包覆模製或沈積。在操作606處,介電質填充物112填充在鄰近晶粒106之間所限定的空間。介電質填充物112亦填充在安置於晶粒106與內插件104之間的焊料連接118之間所限定的填隙空間。介電質填充物112通常安置成大於晶粒106之頂部表面142的高度,使得晶粒106基本上完全嵌入填充物112內。
在操作608處,介電質填充物112經圖案化以創建穿過填充物112之孔302,該等孔暴露內插件104之頂部表面138之部分704,如圖7D中所說明。可藉由蝕刻介電質填充物112、壓印介電質填充物112、對介電質填充物112鑽孔或機械加工、對介電質填充物112雷射鑽孔或藉由使用另一合適技術來創建孔302。在圖7D中所描繪之實例中,使用雷射器以將孔302形成於晶粒106之間及形成於晶粒106與內插件104之邊緣208之間。
在操作610處,晶種層304沈積於內插件104之頂部表面138之藉由填充物112所暴露的部分704上,如圖7E中所說明。晶種層304可使用化學氣相沈積、物理氣相沈積、噴墨印刷或其他適合技術來沈積。晶種層304為隨後沈積在孔302中之金屬材料提供黏著層。晶種層304可視情況沈積於孔302之側壁上。在圖7E中所描繪之實例中,晶種層304由銅製成。
在操作612處,塊狀導體306沈積於晶種層304上,如圖7F中所說明。塊狀導體306可使用無電極鍍製、電鍍、化學氣相沈積、物理氣相沈積或其他適合技術以沈積於晶種層304上。塊狀導體306將孔302完全填充至介電質填充物112之頂部表面706。在圖7F中所描繪之實例中,塊狀導體306為直接鍍製在晶種層304上之銅。
在操作614處,移除塊狀導體306及介電質填充物112之一部分,如圖7G中所說明。塊狀導體306及介電質填充物112之經移除部分可藉由蝕刻、研磨、機械加工或其他適合技術來移除。在圖7G中所描繪之實例中,塊狀導體306及介電質填充物112經研磨使得介電質填充物112(及塊狀導體306)之頂部表面706與晶粒106之頂部表面142基本上共面,使得塊狀導體306及晶種層304形成傳導柱110。移除操作614可視情況移除晶粒106之頂部表面142之一部分以縮減晶粒106的高度。
替代地,可省去晶種層沈積的操作610,且諸如上文所描述的材料502之導熱材料可用以填充孔302並形成傳導柱500。在另一替代實例中,可省去操作610及612,且熱管402可安置於孔302中以形成傳導柱400。
繼續進行到操作616,載體700與內插件104分離,如圖7H中所說明。在操作618處,封裝基板108連接至內插件104之底部表面136,如圖7I中所說明。在封裝基板至內插件附接操作期間,焊料連接118經回焊以將封裝基板108之電路機械地並以電氣方式附接至內插件104之電路。
在操作620處,完成晶片封裝組件100之組裝,如圖7J中所說明。在操作620處完成晶片封裝組件100包括經由晶粒106以將罩蓋102附接至封裝基板108。操作620亦包括在附加晶粒柱110與罩蓋102之間安置TIM 114以確保在柱110與罩蓋102之間的穩健的熱界面,且因此確保在內插件104與罩蓋102之間的穩健的傳導熱傳遞路徑。TIM 114可另外沈積在罩蓋102與晶粒106之頂部表面142之間。
圖8為用於製造具有附加晶粒熱傳遞柱之晶片封裝組件(諸如上文參看圖1至圖5所描述的晶片封裝組件100等)之方法800的流程圖。圖7A至圖7J為晶片封裝組件在圖8之方法800的不同階段之示意性截面視圖。
方法800藉由將內插件104附接至載體700而在操作802處開始,如圖9A中所說明。僅在最初的製造操作期間利用載體700,並且因而,該載體以可移除方式附接至內插件104之底部表面136。在一個實例中,使用可釋放壓敏黏著劑以將內插件104附接至載體700。
在操作804處,晶種層304沈積於內插件104之頂部表面138上,如圖9B中所說明。晶種層304可使用化學氣相沈積、物理氣相沈積、噴墨印刷或其他適合的技術來沈積。晶種層304為隨後經沈積以形成附加晶粒柱110之金屬材料提供黏著層,如下文進一步描述。在圖9B中所描繪之實例中,晶種層304由銅製成。
在操作806處,遮罩材料900沈積於晶種層304上方,如圖9C中所說明。遮罩材料900可為光阻材料或適於晶種層304之圖案化及後續圖案化的其他材料。遮罩材料900可使用旋塗、可流動沈積、化學氣相沈積、噴墨印刷或其他適合技術來沈積。在圖9B中所描繪之實例中,遮罩材料900為聚合光阻材料。
在操作808處,遮罩材料900經圖案化並用於劃分並創建晶種層304之離散部分904,如圖9D中所說明。晶種層將為內插件晶圓上之覆蓋膜。光阻遮罩將經圖案化在此膜上,隨後為進行鍍製。904個突起部應與遮罩材料一樣較高,且區902經限定在遮罩突起部與非晶種層突起部之間。區902經限定在晶種層304之離散部分904之間,其中稍後附接晶粒106。遮罩材料900及晶種層304可使用合適微影及蝕刻技術來圖案化。替代地,可視情況省去操作806,且可剝蝕晶種層304以直接在內插件104之頂部表面138上形成離散部分904。在實例中,晶種層304之離散部分904可藉由雷射剝蝕來形成,以移除駐留在區902中之晶種層304的部分。
在操作810處,塊狀導體306沈積於晶種層304之離散部分904上,如圖9E中所說明。塊狀導體306可使用無電極鍍製、電鍍、化學氣相沈積、物理氣相沈積或其他適合的技術來沈積於晶種層304上。塊狀導體306形成為超過晶粒106之高度的高度,該等晶粒將稍後附接至區902中之內插件104。在圖9E中所描繪之實例中,塊狀導體306為銅且選擇性地直接鍍製在晶種層304上,使得基本上無銅膜沈積在區902中,且所形成的銅柱變為傳導柱110之主要部分。
在操作812處,晶粒106附接至在塊狀導體306之間所限定的在區902中之內插件104的頂部表面138,如圖9F中所說明。在晶粒附接操作期間,焊料連接118經回焊以將晶粒106之電路機械地並以電氣方式附接至內插件104之電路。
在操作814處,介電質填充物112安置於晶粒106及內插件104之頂部表面138上方,如圖9G中所說明。介電質填充物112圍繞塊狀導體306及晶種層304來形成,從而在介電質填充物112中形成其中駐留有塊狀導體306的孔302。介電質填充物112可藉由另一合適的方法旋塗、施配、包覆模製或沈積。在操作814處,介電質填充物112填充在鄰近晶粒106之間所限定的空間。介電質填充物112亦填充在安置於晶粒106與內插件104之間的焊料連接118之間所限定的填隙空間。介電質填充物112通常安置成大於晶粒106之頂部表面142的高度,使得晶粒106基本上完全嵌入填充物112內。
在操作816處,移除塊狀導體306及介電質填充物112之一部分,如圖9H中所說明。塊狀導體306及介電質填充物112之經移除部分可藉由蝕刻、研磨、機械加工或其他適合的技術來移除。在圖9H中所描繪之實例中,塊狀導體306及介電質填充物112經研磨使得介電質填充物112(及塊狀導體306)之頂部表面706與晶粒106之頂部表面142基本上共面,使得塊狀導體306及晶種層304形成傳導柱110。如上文所論述,移除的操作816可視情況移除晶粒106之頂部表面142的一部分以縮減晶粒106之高度。
在操作818處,載體700與內插件104分離,如圖9I中所說明。在操作820處,封裝基板108連接至內插件104之底部表面136,如圖9J中所說明。在封裝基板至內插件附接操作期間,焊料連接118經回焊以將封裝基板108之電路機械地並以電氣方式附接至內插件104之電路。
在操作822處,完成晶片封裝組件100之組裝,如圖9K中所說明。操作822類似於上文所描述的操作620。在操作822處完成晶片封裝組件100包括經由晶粒106以將罩蓋102附接至封裝基板108。操作822亦包括在附加晶粒柱110與罩蓋102之間安置TIM 114,以確保在柱110與罩蓋102之間的穩健的熱界面,且因此確保在內插件104與罩蓋102之間的穩健的熱傳遞路徑。TIM 114可另外沈積在罩蓋102與晶粒106之頂部表面142之間。
因此,已經提供晶片封裝組件及其製造方法,其利用安置於積體電路(IC)晶粒周圍之複數個附加晶粒熱傳遞柱以改良晶片封裝組件內之豎直熱傳遞。附加晶粒熱傳遞柱在罩蓋與基板(諸如內插件或封裝基板)之間有利地提供穩健的傳導熱傳遞路徑。附加晶粒熱傳遞柱亦可選擇性地定位以改良橫越封裝組件之熱傳遞輪廓。至晶片封裝組件之罩蓋的增強的熱傳遞顯著地改良可靠性及效能,同時亦縮減可能誘發翹曲或提供IC晶粒之不充分溫度控制的熱點。另外,附加晶粒熱傳遞柱自內插件移除熱量之能力顯著地縮減在晶片封裝組件內之熱耦合及溫度上升,從而有利地提高電遷移(EM)壽命。
