  • III-V light emitting device having low Si—H bonding dielectric layers for improved P-side contact performance
    Patent number: 11538963
    Abstract: A multilayer light emitting device having a plurality of low Si—H bonding dielectric layers is disclosed for improved p-GaN contact performance. Improved p-side contact resistance is provided using one or more bonding, via or passivation layers in a multilayer light emitting structure by the use of processes and dielectric materials and precursors that provide dielectric layers with a hydrogen content of less than 13 at. %.
