Abstract: Semiconductor dice from a scribed wafer are first separated by a stretched cloth. The dice on the stretchable cloth are then lined up with a target unit and transferred by pressure to a target unit to form a matrix. The pressure can be exerted by pressing individually the dice from the stretchable cloth to the target unit. Alternatively, the dice from the stretchable cloth can first be transferred to a transfer unit before being compressed to the target unit. The transfer unit may also be a perforated board to the hold the dice in place before the dice are soldered to the target unit.

Abstract: A dispensing nozzle device for dispensing processing materials to an output region, includes a body and a plurality of first conduits. The body is formed with a first chamber, a second chamber, a plurality of through holes in communication with the first chamber and the second chamber, and a dispensing nozzle conduit for communicating the second chamber with the output region. The plurality of first conduits are respectively in communication with the plurality of through holes and have a plurality of openings received within the second chamber. A gap is formed between each of the first conduits and corresponding one of the plurality of through holes.

Abstract: A transparent conductive layer is deposited between the electrode and the semiconductor diode to spread the current evenly to the diode and to reduce the series resistance. Tin indium oxide can be used as the transparent conductive layer. The transparent conductive layer is particularly applicable to a blue light emitting diode, where InGaN is used as the light emitting layer.

Abstract: A sound generator for storing and reproducing audio signal with reduced memory storage, which is accomplished by: (a) the technique of Adaptive Differential Pulse Code Modulation (ADPCM), and (B) the elimination of silence period from memory storage but regenerating the silence signal at output.
