Patent ID: 8609512

Claim:
An improved method for singulation of compound electronic devices using a laser processing system, wherein a plurality of said compound electronic devices are manufactured in an assembly that includes a first substrate and a second substrate arranged in layers, said plurality of said compound electronic devices being arranged so as to provide streets between said compound electronic devices, and said laser processing system having a laser beam having parameters, said laser beam operative to laser machine said assemblies, the improvements comprising: predetermining first laser parameters associated with performing a through cut on said first substrate; predetermining second laser parameters associated with performing a scribe on said second substrate; laser machining said through cut in said first substrate with said laser beam using first predetermined laser parameters, said through cut coincident with one of said streets between said compound semiconductor devices; laser machining said scribe in said second substrate with said laser beam using second predetermined laser parameters, said scribe in said second substrate being aligned with said through cut in said first substrate; and singulating said compound electronic devices by mechanically cleaving said second substrate along said scribe.
