Description
本願は、2016年6月2日に出願された米国仮出願第62/344,439号、および2016年9月9日に出願された米国仮出願第62/385,744号に対する優先権を主張するものであり、これらの各々は、全体的に参照により本明細書中に援用される。本願は、2017年6月2日に出願された同時係属中の米国出願第15/612,355号に関連しており、該出願は、全体的に参照により本明細書中に援用される。
(Δa1×t1)=(Δa2×t2) 方程式1
式中、Δa1は、半導体1に対する材料1の格子誤整合を表し、t1は、層304の厚さを表し、Δa2は、半導体1に対する材料2の格子誤整合を表し、t2は、層306の厚さを表す。方程式1が該当する場合、層304および306は、層302上のこれらの層の効果が相互に相殺するように、歪み平衡の状態となる。故に、層302上には結果として生じる歪みは存在しない。このスタックは、格子構造内の僅かなずれを伴って反復されながら、機械的安定性を維持し、層構造300の格子定数を半導体1(302)の格子定数から構造300上に堆積されるべき代替材料の格子定数に遷移してもよい。
