Flip-chip structure for light emitting diode (LED) with silicon substrate, has conductors defined as plus and minus poles by chip

摘要

The Si substrate (1) contains, on one surface, evenly spaced conductors (11), between which is fitted a current interrupting zone (12). At least one chip (2) has on the same surface a plus (21) and a minus terminal (22). They are so fitted, as flip-chip, on the substrate that the two terminals are electrically coupled to the conductors. Thus both end of conductors are defined as plus and minus poles by the chip. The conductors, not coupled to chip, can be connected to external current source.
