摘要： A method for processing a single-crystal semiconductor wafer is provided which is capable of minimizing a dead space to maximize the number of elements per one wafer and preventing leakage luminescence and a reduction in luminance. A phosphor is deposited on each of a plurality of regions defined in the wafer at predetermined intervals and a water-resistant protective film is formed on the phosphor. Then, the wafer is cut for every one of the regions by means of a dicing saw using cutting water, to thereby provide a plurality of chips. The chips are subject to calcination during a calcination step in manufacture of fluorescent display device in which the chips are used as a display section, resulting in the protective film being evaporated.

摘要： An active matrix drive fluorescent display device capable of preventing misluminescence of phosphor layers. A semiconductor chip which includes a plurality of luminous dots arranged in a matrix-like manner and is arranged in an envelope is covered on a cut surface thereof rendered electrically GND with an insulating cover layer. Such construction eliminates a failure in insulation between electrodes arranged on the semiconductor chip, to thereby prevent misluminescence of the luminous dots, leading to an increase in display quality.
