該詳細說明參考圖式以實例方式闡釋本發明之實施例以及優點及特徵。
參考圖1,提供一導管晶粒10且導管晶粒10包含一第一裝置層20、一第二裝置層30、一絕緣層40、一第一接合墊50及一第二接合墊60。第一裝置層20具有一主體21,主體21具有一上表面22及與上表面22相對之一下表面23。第一裝置層20亦經形成以界定其中之一腔25,腔25至少自上表面22凹入。
第二裝置層30具有一主體31,主體31具有一上表面32及與上表面32相對之一下表面33。第二裝置層30之下表面33接合至第一裝置層20之上表面22從而至少在上表面22處將腔25密封。第二裝置層30進一步包含界定於腔25上面之一隔膜34及靠近隔膜34及腔25以可操作方式安置之一壓阻壓力感測器35以及一絕緣體36。絕緣體36安置於第二裝置層30之上表面32上且具有界定於其中之一開口37,開口37曝露壓阻
壓力感測器35之一部分351。
絕緣層40具有一主體41,主體41具有一上表面42及與上表面42相對之一下表面43。絕緣層40之上表面42接合至第一裝置層20之下表面23以提供導管晶粒10之支撐、穩定性及強度。第一接合墊50由導電材料形成且電耦合至經由開口37曝露之壓阻壓力感測器35之部分351。第二接合墊60類似地由導電材料形成且安置於絕緣層40上。如將在下文參考圖15闡述,第一接合墊50與第二接合墊60可經由一線接合彼此電耦合,其中第二接合墊60進一步電耦合至一外部連接。
根據實施例,絕緣層40在表面積方面實質上比第一裝置層20或第二裝置層30大。因此,絕緣層40之一部分401自第一裝置層20及第二裝置層30之邊界向外延伸以使得上表面42可至少部分地曝露。第二接合墊60可安置於(舉例而言)部分地曝露之上表面42之部分上。因此,第二接合墊60可實質上比第一接合墊50長。
在此構造之情況下,腔25可界定為一真空或具有一已知、預定義內部壓力。在任一情形中,當導管晶粒10曝露至未知氣氛條件時,腔25之一內部與導管晶粒10之一外部之間的一壓力差可足以致使第二裝置層30之隔膜34取決於腔25之內部之壓力低於還是高於導管晶粒10之外部之壓力而向內或向外彎曲。隔膜34之此彎曲施加一張力至壓阻壓力感測器35且在其中誘發一電流。藉由將適當電路耦合至壓阻壓力感測器35,可判定此電流之一量值,且因此可計算腔25之外部處之一壓力。
根據替代實施例且參考圖2,一通氣通道70可形成於絕緣層40中。如圖2中所展示,腔25可自第一裝置層20之上表面22及下表面23兩者凹入。因此,通氣通道70可經由靠近下表面23之一互連與腔25流體連通以便可主動地控制腔25內之一壓力。
根據其他實施例,應理解第一裝置層20及第二裝置層30可形成
或以其他方式提供為一單個裝置層。此外,儘管第一裝置層20及第二裝置層30之一組合厚度可係大約390 μm或更小,但第二裝置層30之一厚度可係大約1 μm至4.5 μm或更小。類似地,絕緣層40之一厚度可係大約390 μm或更小,但應理解至少此厚度可係實質上可變的。
根據另外其他實施例,第一裝置層20及第二裝置層30可各自由一半導電材料(諸如矽)形成,而絕緣層40可由玻璃或某一其他非導電材料形成。
參考圖3至圖15,將在下文提供製造如上文所闡述之一導管晶粒之一方法。應理解,為清晰及簡潔起見,說明將一般而言係關於圖1中所展示之導管晶粒10之例示性實施例。製造如圖2中所展示之具有通氣通道70之導管晶粒10之方法係實質上類似的且不需要單獨闡述。
如圖3及圖4中所展示,該方法首先包含形成具有一第一裝置層101之一晶圓100(參見圖3)及具有一第二裝置層111之一晶圓110(參見圖4)。晶圓100可形成為一絕緣體上矽(SOI)晶圓,其中第一裝置層101具有一上表面1011及一下表面1012且由一n型或p型半導體(亦即,矽)形成。第一裝置層101安置於一第一埋入式氧化物層102上,第一埋入式氧化物層102本身安置於一第一處置層103上。第一處置層103可由一n型或p型半導體形成。晶圓110可形成為一絕緣體上矽(SOI)晶圓,其中第二裝置層111具有一上表面1111及一下表面1112且由一n型半導體(亦即,矽)形成。第二裝置層111安置於一第二埋入式氧化物層112上,第二埋入式氧化物層112本身安置於一第二處置層113上。第二處置層113可由一n型或p型半導體形成。
如圖5中所展示,一腔120形成於第一裝置層101中。腔120被圖解說明為三角形且自第一裝置層101之上表面1011凹入,但應理解此僅係例示性的且腔120可具有各種形狀及大小。根據實施例,腔120可由一濕式蝕刻製程(諸如氫氧化鉀(KOH)蝕刻或氫氧化四甲銨(TMAH)
蝕刻)或一乾式蝕刻製程(諸如深反應離子蝕刻(DRIE))形成。
參考圖6及圖7,晶圓110經反轉且第二裝置層111之上表面1111與第一裝置層101之上表面1011接合以使得第二裝置層111在第一裝置層101之上表面1011處將腔120密封(參見圖6)。可將此操作進行為在大約900℃至1200℃之一升高溫度下之一矽熔融接合製程。在接合之後,如圖7中所展示,藉由一濕式蝕刻製程(諸如KOH蝕刻或TMAH蝕刻)移除第二處置層113且藉由濕式或乾式蝕刻移除第二埋入式氧化物層112以使得第二裝置層111之下表面1112曝露且現在位於腔120上面之第二裝置層111之一部分界定為一隔膜130。
參考圖8,一第一絕緣體140安置於第二裝置層111之現在曝露之下表面1112上且一第二絕緣體141安置於第一處置層103之一下表面1031上。第一絕緣體140及第二絕緣體141可各自提供為一鈍化層,諸如(舉例而言)一層二氧化矽或某一其他非導電材料。第一絕緣體140及第二絕緣體141之安置可藉由沈積或生長製程達成。
參考圖9及圖10,然後在第二裝置層111中形成一壓阻壓力感測器150及其一互連部分151以使得壓阻壓力感測器150靠近腔120及隔膜130以可操作方式安置(參見圖9)。壓阻壓力感測器150及互連部分151之形成可包含p型摻雜劑擴散及植入中之至少一或多者。此時,第一絕緣體140使壓阻壓力感測器150與互連部分151絕緣。因此,一開口160可藉由濕式或乾式蝕刻中之至少一或多者界定於第一絕緣體140中以使得壓阻壓力感測器150之至少互連部分151透過開口160而曝露(參見圖10)。
參考圖11及圖12,一第一接合墊170經由開口160電耦合至壓阻壓力感測器150之互連部分151(參見圖11)。可藉由一金屬化製程(包含,舉例而言,一適合金屬或金屬合金(亦即,鋁)之沈積處理)進行此操作。此時,如圖12中所展示,可藉由一濕式蝕刻製程(諸如KOH蝕
刻或TMAH蝕刻)移除第一處置層103。然後可在第一絕緣體140中蝕刻一第一通孔180,可藉由濕式蝕刻、乾式蝕刻或濕式與幹式蝕刻之一組合在第二裝置層111及第一裝置層101中蝕刻一第二通孔181且可藉由濕式或乾式蝕刻移除第一埋入式氧化物層102。
參考圖13,然後將一絕緣層190接合至第一裝置層101之下表面1011。絕緣層190可由玻璃或另一適合非導電材料形成且可具有接合至其之由導電材料形成之一第二接合墊200。根據實施例,第二接合墊200可預先安置於絕緣層190之一上表面1901上以使得第二接合墊200透過第一通孔180及第二通孔181而曝露。
一旦絕緣層190經接合至第一裝置層101之下表面1011,便可進行原本將有損壞上文所闡述之元件之風險之額外處理操作。此等額外處理操作可包含(舉例而言)將第二接合墊200電耦合至第一接合墊170及(參考圖14)單粒化處理。在單粒化處理期間,將導管晶粒10自額外材料切下或切掉,該額外材料可在額外導管晶粒之處理中使用。
根據本發明之其他態樣且參考圖1及圖15,圖1之導管晶粒10可進一步具備經組態以將第一接合墊50電耦合至第二接合墊60之一第一端之佈線300(諸如一線接合)。另外,如圖15中所展示,導管晶粒10可包含用於將一外部連接器500電耦合至第二接合墊60之一第二端之一焊料接合400。在此情形中,佈線300與焊料接合400之間的一距離D可係可變的且長達1 mm或更大,其中絕緣層40實質上長於第一裝置層20、第二裝置層30及絕緣層40之厚度。
另外,仍參考圖1及圖15,應理解導管晶粒10可包含多個壓阻壓力感測器35及對應數目個第一接合墊50及第二接合墊60以及對應數目個焊料接合400及外部連接器500。多個第一接合墊50可以一軸向交錯形式安置於絕緣體36上,因此要求多個第二接合墊60亦以一對應交錯形式安置。在此等情形中,多個焊料接合400及多個外部連接器500亦
可以一對應交錯形式安置。另一選擇係,若距離D足夠長(例如,其中大部分軸向位移之接合墊對與對應焊料接合400分離),則多個焊料接合400及多個外部連接器500可以一對準形式安置。
儘管僅已結合有限數目個實例性詳細闡述了本發明,但應容易地理解本發明並不限於此等所揭示之實施例。相反,本發明可經修改以併入此前並未闡述但與本發明之精神及範疇相稱之任何數目個變化形式、更改形式、替代形式或等效配置。另外,儘管已闡述本發明之各種實施例,但應理解,本發明之態樣可僅包含所闡述之實施例中之某些實施例。因此,不應將本發明視為受前述說明限制,而僅受隨附申請專利範圍之範疇限制。
