Patent ID: 8518748

Claim:
A method for providing a plurality of laser diode submounts for use in an energy assisted magnetic recording (EAMR) disk drive comprising: removing a portion of a silicon substrate to form a plurality of trenches therein, the plurality of trenches having sidewalls and surrounding a silicon island corresponding to a laser diode submount of the plurality of laser diode submounts, the plurality of trenches corresponding to a thickness of the laser diode submount, the silicon island having a top surface and a plurality of facets corresponding to the sidewalls of the plurality of trenches; providing at least one insulator for the top surface and the plurality of facets of the silicon island for the plurality of trenches; providing metallization on the top surface and the plurality of facets of the silicon island for the plurality of trenches, a first portion of the metallization on the top surface corresponding to under bump metal (UBM) for at least one solder pad, a second portion of the metallization corresponding to electrical traces; providing at least one solder pad on the UBM on the top surface of the silicon island for the plurality of trenches; releasing the silicon island for the plurality of trenches from the silicon substrate.
