Abstract
Reported to contain a SemiLEDs die on flexible copper substrate and the
subject of much controversy and feuding between Nichia and Seoul
Semiconductor, this device has indeed a very interesting die.
MuAnalysis has used a large variety of analytical techniques including
electron microscopy with photochemical delineation and EDX to probe the
technology of this LED lamp and reveal its secrets. Protection circuitry,
process sequence and epi-stack are described in detail supported by plenty of
photos, tables and graphs.
