| 英文摘要 | A method and system for providing a laser diode submount for use in an energy assisted magnetic recording disk drive are described. A portion of a silicon substrate is removed, forming trenches therein. Each trench has sidewalls, surrounds a silicon island corresponding to a laser diode submount, and corresponds to a thickness of the laser diode submount. The silicon island has a top surface and a facets corresponding to the trench sidewalls. Insulator(s) for the top surface and facets of the silicon island are provided. Metallization is provided on the top surface and facets of the silicon island. A first portion of the metallization on the top surface corresponds to under bump metal (UBM) for solder pad(s). A second portion of the metallization corresponds to electrical traces. Solder pad(s) are provided on the UBM. The silicon island is released from the silicon substrate. |
