Zusammenfassung:An LED includes a first pedestal and may be fabricated by coating a first phosphor layer on the LED, thinning the first phosphor layer to expose the first pedestal, forming a second pedestal on the first pedestal, coating a second phosphor layer and thinning the second phosphor layer to expose the second pedestal. Alternatively, an LED having a pedestal is coated with a first phosphor layer, coated with a second phosphor layer and then planarized to expose the pedestal. Related structures are also provided.
