Description
本發明涉及一種雙極高電子遷移率電晶體,尤其至少在次集極及頂蓋結合層的碳濃度至少大於5×1017
cm-3
,及/或氧濃度至少大於1×1018
cm-3
。
製作異質接面雙極性電晶體(Heterojuction Bipolar Transistor,HBT)及假性高電子遷移率電晶體(Pseudomorphic High Electron Mobility Transistor,PHEMT)的過程,以砷化鎵及其他三五族材料,利用磊晶成長的方式逐層地堆疊形成,比起一般以矽為基底的場效電晶體(Field-Effect Transistor),以具有較高電子遷移率(Mobility),並且對於高頻信號,比如L-頻帶(1-2GHz)、C-頻帶(4-8GHz)或是更高頻的頻帶,具有較低的失真放大特性與較高的功率,尤其是無線通訊裝置中功率放大器(Power Amplifier,PA),以普遍使用於手持式通訊裝置,例如手機(Mobile Phone)。
採用矽基的BiCMOS的概念,將異質接雙載子電晶體(HBT)功率放大器、假性高電子移動率電晶體(pHEMT)微波開關、低雜訊放大器(pHEMT)、偏壓電路及邏輯電路(pHEMT)整合成單一晶片,這是製作雙極高電子遷移率電晶體(BiHEMT)的原始構想,這可以使得模組的尺寸縮小,從原本的2顆元件縮小至1顆,且受惠於此,即可降低材料以及封裝成本,有效降低整體成本。
然而,目前在製作雙極高電子遷移率電晶體所碰到的問題是,由於BiHEMT之次集極層以及頂蓋結合層中的缺陷在磊晶成長過程中高,會使得鄰近層(例如,pHEMT中的蝕刻終止層(etching stop layer)、蕭特基層(Schottky layer)以及摻雜層(donor layer))中的元素、摻雜物(dopant)、以及晶格缺陷向外擴
散,而使得出現遷移率下降、電阻上升,而使得元件劣化的現象,更因此,難以控制製程參數,因此,需要一種能解決此問題的結構及方法。
本發明的主要目的在於提供一種雙極高電子遷移率電晶體(BiHEMT),該雙極高電子遷移率電晶體包含由下到上堆疊的一基板、一假性高電子遷移率電晶體次結構、一次集極及頂蓋結合層以及一異質接面雙極性電晶體次結構,該次集極及頂蓋結合層與該假性高電子遷移率電晶體次結構組合形成為一假性高電子遷移率電晶體(Pseudomorphic High Electron Mobility Transistor,PHEMT),而該次集極及頂蓋結合層與該異質接面雙極性電晶體次結構組合形成一異質接面雙極性電晶體(Heterojuction Bipolar Transistor,HBT),其中該次集極及頂蓋結合層具有碳濃度在5×1017
cm-3至1×1020
cm-3
的範圍內,及/或是氧濃度在1×1018
cm-3
至1×1020
cm-3
的範圍內。
該次集極及頂蓋結合層可為單層結構,或是包含頂蓋層、分隔層以及次集極層的三層結構,當次集極及頂蓋結合層為三層結構時,其中頂蓋層與假性高電子遷移率電晶體次結構組合形成一假性高電子遷移率電晶體,而次集極層與異質接面雙極性電晶體次結構組合形成一異質接面雙極性電晶體,使得假性高電子遷移率電晶體與異質接面雙極性電晶體藉由該分隔層而相互結合,且該頂蓋層、分隔層以及次集極層的至少其中一層的碳濃度在5×1017
cm-3
至1×1020
cm-3
的範圍內,及/或是氧濃度在1×1018
cm-3
至1×1020
cm-3
的範圍內。
本發明主要的特點在於,透過製程的環境的設定,使得至少在次集極及頂蓋結合層含有碳濃度在5×1017
cm-3
至1×1020
cm-3
的範圍,及/或是氧濃度在1×1018
cm-3
至1×1020
cm-3
的範圍;更進一步地可以應用在假性高電子遷移率電晶體次結構中的蕭特基層及蝕刻中止層,如此可以在磊晶成長的過程中,維
持晶格的穩定性,而避免影響到摻雜物、元素、或是空隙、缺陷在磊晶成長的過程向鄰近的層擴散,而防止了遷移率降低、電阻變大的問題,且能夠維持製程的穩定性。
