Abstract:
A method includes mounting a ceramic phosphor (102) on an acrylic-free and metal-containing catalyst-free tacky layer (108) of a dicing tape (104), dicing the ceramic phosphor (102) from the dicing tape (104) into ceramic phosphor plates (11)2, removing the ceramic phosphor plates (112) from the dicing tape (104), and attaching the ceramic phosphor plates (112) on light-emitting device (LED) dies.
