Description
本発明の実施形態によれば、コンデンサ、抵抗体、誘導子、及びダイオードのような回路要素は、半導体発光装置において半導体層と、装置をマウント又は他の外部装置に接続するのに使用される接続層との間で装置と一体化することができる。図4及び図5に示されている接点金属を接続層から隔離する誘電体層116及び120は、回路要素の形成を容易にする。
図6は、図7に示す回路図に従った装置の一部分の断面図である。メサが、1つ又はそれよりも多くのn型層、1つ又はそれよりも多くの発光層、及び1つ又はそれよりも多くのp型層を含むエピタキシャル構造110内に形成される。メサは、n接点114が形成されるn型層を露出させる。p接点112は、エピタキシャル構造110の残りの表面上に形成される。図の右側で、p接点112は、抵抗体162を通じて接続層122に接続され、抵抗体は、誘電体層160a及び160bによって装置内の他の金属層から隔離される。
図6に戻れば、n接点114は、図の左側でn接続層124に接続される。コンデンサ164は、p接続層122及びn接点114に接続される。誘電体層160b及び160cは、コンデンサ164の近くでn接点114及びn接続層124からp接続層122を絶縁する。
図10は、図11に示す回路図に従った装置の一部分の断面図である。図6におけるように、n接点114は、エピタキシャル構造110内に形成されたメサ内のn型領域に接続される。p接点112は、エピタキシャル構造110の残りの表面上に形成される。ESD保護ダイオード172aは、P接続層122とn接点114との間に配置される。p型シリコン層172aが、n接点114に接触し、n型シリコン層172cが、p接続層122に接触し、i型シリコン層172bが、p型層172aとn型層172cの間に配置される。代替的に、ESD保護ダイオード172は、金属層の間に挟まれたn型又はp型シリコン層を含むショットキーダイオードとすることができる。ESD保護ダイオード172のシリコン層は、例えば、プラズマ促進化学気相蒸着(PECVD)によって形成されたアモルファス層か、又はアモルファス層のPECVDの後のレーザパルス処理又は焼き鈍しによって形成された多結晶層とすることができる。PECVDによって形成されたシリコン層は、エピタキシャル構造110並びにp接点112及びn接点114のような装置の他の部分に対する損傷を回避するのに十分低い温度で堆積させることができる。例えば、ESD保護ダイオード172のシリコン層172a、172b、及び172cは、250℃未満の温度で形成することができる。図10では、明確にするために、シリコン層172aは、n金属114と直接接触する状態で示され、シリコン層172cは、接続部122と直接接触する状態で示されている。一部の実施形態では、1つ又はそれよりも多くの付加金属層をシリコン層172a及び172cと、それらが図10において接続している金属層との間に配置することができる。これらの付加金属層は、例えば、シリコン層172a及び172cのうちの一方又は両方、又は保護金属層へのオーミック接点とすることができる。
