Description
この出願は、2007年7月19日付けの米国仮出願60/950,797および2008年7月17日付けの米国特許出願12/175,375に基づく優先権の利益を主張し、それぞれの全体の開示が、この出願においてすべての目的のために組み込まれる。
以下に開示するある実施形態は、概して、電子部品を基板に取付けるための方法に関している。より詳細には、ある実施例は300℃以下の温度を用いたダイの取付け方法およびそのような方法を用いて作られた装置に向けられる。
ダイを基板に取付けるに際しては、ダイと基板との間にジョイントまたは電気カップリングが用いられる。ジョイントを作るときには、300℃を越える高い温度を用いてもよい。そのような高い温度は、傷つきやすいダイに損傷を与えて、装置の性能を劣化させ、あるいは寿命を限られたものにする可能性がある。
以下に述べる特徴、局面および実施例は、200℃以上の温度で機能および/または作動するジョイントに向けられる。典型的には錫合金である従来のはんだは、錫が低融点金属であるために、この温度では即座に破損する。ここで説明するジョイントの実施形態は、900℃で融解する銀を含むことにより、そのような高い温度において作動することができる。ある局面においては、ジョイントをもたらすために、300℃よりも低い温度で、ある量のキャッピング剤とともに銀ナノ粉末を焼結する工程を用いてもよい。以下においてさらに論ずるように、選択された量のキャッピングは高密度の銀ジョイントをもたらし、圧力焼結の間にシリコンダイに亀裂が入ることを防止することができる。
ここで述べられるある実施形態は、ダイを含むがそれに限定されない電子部品を、プレプレッグ、プリント回路基板または電子デバイスの製造に一般に用いられるその他の基板を含むがそれらに限定されない、選択された基板(またはその領域)に取付けるために使用される材料および装置に向けられる。
および2−6炭素原子を含む脂肪族側鎖を有する芳香族化合物を含むが、これらに限られない。適切な溶媒系は、ここで述べる例示的溶剤、および、例示的な溶剤に対して溶解性、混和性、または一部混和性を有する他の流体を含む。ある実施例では、溶剤の組み合わせが単一相を提供する。溶剤の混合に用いるときに単一相を達成するために、各溶剤の量を、溶剤を混合する際に単一相になるように調節してもよい。混合の際に1相以上存在する場合には、1つ以上の溶剤の相対的な量を変更することができ、たとえば、単一相が観察されるまで増加または減少させることができる。
