Abstract
A monolithic LED chip is disclosed comprising a plurality of junctions or sub-LEDs (“sub-LEDs”) mounted on a submount. The sub-LEDs are serially interconnected such that the voltage necessary to drive the sub-LEDs is dependent on the number of serially interconnected sub-LEDs and the junction voltage of the sub-LEDs. Methods for fabricating a monolithic LED chip are also disclosed with one method comprising providing a single junction LED on a submount and separating the single junction LED into a plurality of sub-LEDs. The sub-LEDs are then serially interconnected such that the voltage necessary to drive the sub-LEDs is dependent on the number of the serially interconnected sub-LEDs and the junction voltage of the sub-LEDs.

32. A LED chip, comprising:
-
a plurality of sub-LEDs mounted on a submount, wherein said sub-LEDs are formed from a single junction LED; and electrically conductive and electrically insulating features serially interconnecting said sub-LEDs such that an electrical signal applied to said serially interconnected sub-LEDs along said electrically conductive features spreads to said serially interconnected sub-LEDs. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39)
