Abstract
An LED has both its p and n bonding pads on the p side of the wafer for simultaneous solder bump alignment and electrical connection of the LED with a device carrier. A groove is formed dividing the p material of the device into an active region and an inactive region. The groove also provides a path for the device's n-contact, which extends from the n-material at the base of the groove, up the side of the groove, to the n bonding pad on the surface of the inactive p material.
