The fabrication technology in quantity of GaAlAs single heterostructure red LED’s has been investigated in detail. A growth boat with new structure has been designed to carry out simultaneous LPE growth on many substrates. An effort has been made to obtain the optimum solution composition and the best growth parameters. A growth process for epitaxial wafers with excellent proformance and good reproducibility has been established. The LED’s dices fabricated by this process have emission wavelength of 660mm
mean brightness of 4.5mcd at 20mA and the highest value of 6.2mcd.
