Separation method for Gallium Nitride devices on lattice-mismatch substrates
A method for separating semiconductor devices is disclosed. The method includes providing a substrate having one or more epitaxial layers formed thereon, forming trenches in the one or more epitaxial layers, forming scribe lines in a surface of the substrate, wherein the locations of the scribe line...

| Zusammenfassung: | A method for separating semiconductor devices is disclosed. The method includes providing a substrate having one or more epitaxial layers formed thereon, forming trenches in the one or more epitaxial layers, forming scribe lines in a surface of the substrate, wherein the locations of the scribe lines correspond to the locations of the trenches, and separating the semiconductor devices by cracking the wafer along the scribe lines. |
