Abstract: A circuit substrate including a base layer and a plurality of lead units arranged as an array is provided, wherein the base layer has a plurality of through grooves, and the lead units are disposed on the base layer. Each of the lead units includes a common terminal and at least three leads. The common terminal is capable of being divided into a plurality of electrodes connected with each other. The leads are extended outwards from the edge of the common terminal, and each of the leads is extended outwards from the edge of one of the electrodes. The through grooves expose the common terminals of the lead units.

Abstract: A method for packaging LED device comprises following steps: (1) A substrate with a cavity is provided; (2) A electrode layer is formed and located on the cavity and the surface of the substrate; (3) A opening through the cavity is formed, whereby a anode and a cathode are separated by the opening; (4) A LED chip is disposed on the bottom of the cavity and the opening, where the led chip is electrically connected to the anode and the cathode; (5) The cavity with the opening is filled with packaging material; (6) The packaging material is hardened, thereby the hardened packaging material with a recess that corresponding to the top of the chip; and (7) The LED device is formed by performing a cutting process along a cutting line in the cavity.

Abstract: At least a first reticle is stored in a housing of a stocker. A first gas is delivered to the housing. At least one reticle pod having an additional reticle is delivered into a enclosure within the housing of the stocker. A second gas different from the first gas is delivered to the enclosure. The reticle pod is automatically retrieved from the enclosure. The delivery and retrieval of the reticle pod and delivery of the first gas and the second gas are automatically controlled.
