METHOD FOR MANUFACTURING DIFFUSION REGION OF RARE EARTH ELEMENT ION, LIGHT-EMITTING DIODE, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To enable control of the desired position of the concentration distribution peak values of rare earth element ions and adjustment of the luminous intensity of a light-emitting element, by keeping the rare earth element ions in a predetermined distribution conditions and moving the diffusion region of rare earth element ions in a substrate depthwise direction through heat treatment.;SOLUTION: A manufacturing method comprises the steps of forming a diffusion region 16 of rare earth element ions, having a predetermined distribution in a substrate 11, and keeping rare earth element ions in a state of predetermined distribution and making the diffusion region 16 of rare earth element ions move, in the depthwise direction of the substrate 11 through heat treatment.;COPYRIGHT: (C)2006,JPO&NCIPI
