Abstract: A method for making a light emitting diode lighting module includes steps of: (a) packaging a plurality of light emitting diode dies respectively on a plurality of die-mounting parts of a metal lead frame to form a plurality of light emitting diodes, respectively; and (b) cutting off supporting parts of the lead frame so as to form a connecting structure through which the light emitting diodes are connected to each other in one of serial, parallel, and serial-and-parallel connecting manners.

Abstract: A new method is provided for the creation of the bit line contact plug. CUB capacitors typically are located adjacent to the bit line contact plug, a parasitic capacitance therefore exists between the CUB and the contact plug. Typical interface between the CUB and the bit line contact plug consists of a dielectric. By creating an air gap that partially replaces the dielectric between the CUB and the bit line contact plug, the dielectric constant of the interface between the bit line and the CUB is reduced, thereby reducing the parasitic coupling between the bit line contact plug and the CUB. This enables the creation of CUB capacitors of increased height, making the CUB and the therewith created DRAM devices better suited for the era of sub-micron device dimensions.

Abstract: The present invention relates to a pattern-changing structure for a projection light system comprising a base plate, a rotating disc, a motor, and a patterned disc, and the motor is mounted at one lateral side of the base plate, and the shaft center of the cam passes through the center of the base plate and the rotating disc, to form as a unit. A crankshaft having two ends is mounted to the base plate, and one end is mounted with a stopping region and the other end is mounted with a spring hook. The spring hook is connected to a pulling spring and a cavity hole is provided on the base plate for the protrusion of the stopping region. The rotating disc is also provided with a plurality of positioning teeth. When the motor rotates, the cam controls the crankshaft to protrude/extend or to retract, and the positioning teeth is either extended or retracted. Thus, the rotating disc is rotated intermittently and various pattern images are obtained.
