Description
エピタキシャル成長に用いられる最初の支持体101は、そのような支持体は、非常に高価なことがあるのだが、破壊されないので、リサイクルが可能である。
機械的剥離では、SiC、GaNを含め、ケミカルエッチングが不可能であり、プラズマまたはイオンビームエッチングに長時間かかるような、あらゆるタイプの支持体が分離する。最初の支持体の機械的分離は、リフトオフレーザー分離の場合のように、透明な材料に限られることはなく、ケミカルアタックに反応する材料にも限られない。機械的剥離は、普遍的で高価でない剥離手段である。
使用される異種の金属層は、所望の特性のすべてを有している。オーム接触機能とミラーの確保、無制御の拡散現象による性能低下のない、支持体と活性層間の良好な熱伝導と電気伝導の達成、強度のある材料が選択されることによる優れた機械的挙動、である。
本実施例に使用された剥離可能な基板は、多結晶SiCまたはシリコンから形成された支持体101と、6H−SiCから形成されたエピタキシャル成長表面層102より構成した。これら2つの間には、埋設された酸化物層および剥離可能な界面103がある。GaNおよびAlGaInN合金に基づく活性層を、膜102に、エピタキシャルに付けた。続いて、金属堆積105を、活性層上に堆積した。
・Ni(厚さ5nm)+Au(厚さ5nm):p−層へのオーム接触
・Pt:拡散障壁
・Ag:ミラー形成層
・Au:ボンディング用
・Cr(厚さ5nm):キーイング層
・Au:ボンディング用
本実施例に使用された剥離可能な基板は、Siから形成された支持体101と、GaAsから形成されたエピタキシャル成長表面層102より構成した。これら2つの間には、埋設された酸化物層および剥離可能な界面がある。GaAsおよびAlGaInP合金に基づく活性層を、GaAs膜に、エピタキシャルに付けた。続いて、金属堆積を、活性層上に堆積した。
・Au/Zn:p−層へのオーム接触
・Ti:拡散障壁
・Au:ミラー形成層およびボンディング用
・Ti(厚さ5nm):キーイング層
・Au:ボンディング用
本実施例に使用された剥離可能な基板は、Siから形成された支持体101と、結晶方位(111)を有するSiから形成されたエピタキシャル成長表面層102より構成した。これら2つの間には、埋設された酸化物層および剥離可能な界面103がある。GaNおよびAlGaInN合金に基づく活性層を、Si膜102に、またはAlNに基づく緩衝層を介して、エピタキシャルに付けた。続いて、金属堆積を、活性層上に堆積した。
・Ni/Cr/Au:Cr拡散障壁が一体化されたp−層へのオーム接触
・Au:ミラーおよびボンディング層
・Cr(厚さ5nm):キーイング層
・Au:ボンディング用
好ましくはGaN(およびAlGaInN合金)またはGaAs(およびAlGaInP合金)に基づく発光ダイオードまたはレーザーダイオードの製造;
上記の成分(図1E参照)の活性層を有する中間基板の製造、
