Title:
LIGHT-EMITTING DIODE ARRAY
Document Type and Number:
Japanese Patent JP3232152
Kind Code:
B2
Abstract:
PURPOSE: To provide a high-density light-emitting diode array, which could not be realized in the past, by protecting a light-emitting part from chippings, even if the length from the light-emitting part of a light-emitting diode array to the end of a chip is made smaller than the size of a chipping.
CONSTITUTION: In a light-emitting diode array having light-emitting dots arranged in a row, a reverse mesa shape 1-6 is formed relative to the end face of a chip directed vertically to the direction, in which light emitting diodes (1-2, 1-3) are arranged relative to the semiconductor substrate 1-1 of a chip constituting the light-emitting diode array, i.e., relative to the end face of the chip facing an adjacent chip. Thus, the reverse mesa shape is formed in the chip end face so that a light-emitting part can be protected from large chippings even if such chippings are generated at the time of dicing.
