Title: Treating method of light-emitting device obtained by processing nitride semiconductor
Inventor: HOOPER STEWART EDWARD
IPC: H01S5/343
Filed: 2007-07-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a treating method which is capable of controlling accurately the growth of a nitride semiconductor layer and improves the light emission characteristics of a light emission device obtained by processing a nitride semiconductor in a short time.  <P>SOLUTION: The treating method comprises (a) a step of disposing in a vacuum chamber a light emission device structure 1' obtained by processing the nitride semiconductor, (b) a step of growing at least one nitride semiconductor layer 2 on the light emission device structure 1', and further a step of supplying active nitrogen to the vacuum chamber, wherein in the step (b), the nitride semiconductor layer 2 is grown using the molecular beam epitaxy (MBE). Use of active nitrogen enables the reduction of the growing temperature necessary for the growth of the nitride semiconductor layer 2 because there is no need for thermal activation of nitrogen species. Further, for example, use of the MBE such as plasma-assisted MBE enables the much more accurate control of the thickness and the composition of the nitride semiconductor layer 2.  <P>COPYRIGHT: (C)2008,JPO&INPIT
