The controller generates the scanning instructions and provides the scanning instructions to the light source.

Abstract: Ion implantation is carried out into a GaN layer of mLEDs to partially or fully convert one or more regions of the crystalline GaN layer to amorphous GaN. As a result, the GaN layer through which light rays propagate have non-uniform refractive indexes that modify propagation paths of some light rays. Ions can be implanted in a region around an active region that emits light to function as an optical waveguide. The ion implanted regions direct light rays that propagate along predetermined directions into predetermined propagation paths thereby to modify the angle of incidence of these light rays. As such, the light extraction efficiency of the mLEDs is increased.

Abstract: There is herein described a process for providing improved device performance and fabrication techniques for semiconductors. More particularly, the present invention relates to a process for forming features, such as pixels, on GaN semiconductors using a p-GaN modification and annealing process. The process also relates to a plasma and thermal anneal process which results in a p-GaN modified layer where the annealing simultaneously enables the formation of conductive p-GaN and modified p-GaN regions that behave in an n-like manner and block vertical current flow. The process also extends to Resonant-Cavity Light Emitting Diodes (RCLEDs), pixels with a variety of sizes and electrically insulating planar layer for electrical tracks and bond pads.
