Abstract: A method of making a transfer head for transferring micro elements, wherein the transfer head includes a cavity with a plurality of vacuum paths and a suite having arrayed suction nozzles and vacuum paths. The suction nozzles are connected to the vacuum path components respectively, and the vacuum path components are formed to connect to vacuum paths in the cavity respectively. The suction nozzles attract or release the micro element through vacuum pressure transmitted by vacuum. When the suite is mounted in the cavity, the upper surface of the suite is arranged with optical switching components for controlling the switch of the vacuum path components and vacuum paths of each path so that the suction nozzles can attract or release required micro element through vacuum pressure; and fabricating a suite with an array micro-hole structure, wherein the array micro-hole structure serves as the vacuum path components and the suction nozzles.

Abstract: A fabrication method for a light emitting diode (LED), including: 1) mounting a LED chip on a substrate; 2) mounting a screen printing template on the LED chip; 3) coating a silicone gel layer over the surface of the screen printing template; 4) printing the phosphor: printing the phosphor over the chip surface via silk screen printing process and recycling the excess phosphor; and 5) removing the screen printing template and baking the phosphor for curing, and coating the cured phosphor over the chip surface. In the packaging method of the present disclosure, the unused phosphor can be recycled because it is not polluted by the screen printing template material.

Abstract: An epitaxial structure of light emitting diode with a current modulation layer, and more specifically, a high-resistivity material is injected to change the current conduction path, and implementation of the main structure is to grow a high-resistivity material (e.g., InxAlyGa1-x-yN) over the N-type conductive layer or the P-type conductive layer till part of current conduction path is exposed through high-temperature H2 in-situ etching in the reacting furnace and to grow the N-type or the P-type conductive layer for coverage. This design for forming a current modulation layer without second epitaxial growth provides the injected current with a better spreading path in the N-type conductive layer and the P-type conductive layer, which more effectively and uniformly injects the current to the active layer and improves luminous efficiency.
