Patent ID: 7811843

Claim:
A method for manufacturing an LED, comprising: preparing an LED wafer comprising a substrate and an epitaxial layer formed on the substrate; cutting the epitaxial layer of the LED wafer into a plurality of LED dies, wherein a gap is defined between every two neighboring dies, and each of the LED dies includes a top surface and an opposite bottom surface attached to the substrate; filling an electrically insulating material in each gap between neighboring LED dies such that the neighboring LED dies are separated from each other by the electrically insulating material; providing a circuit board having a layer of electrically conductive adhesive coated thereon, wherein electrically conductive particles are dispersed in the adhesive; pressing the LED dies against the adhesive to bring the top surfaces of the LED dies into contact with the adhesive such that the LED dies each are electrically connected to the circuit board via some of the electrically conductive particles of the adhesive, in which the electrically insulating material is inserted into the adhesive; and encapsulating the LED dies with a light penetrable material.
