    Abstract: PROBLEM TO BE SOLVED: To realize a method for growing a III-V nitride compound semiconductor having high crystallinity by increasing nitrogen materials contributing to growth. SOLUTION: A material gas, including ammonia gas being the material of nitrogen and carrier gas, is supplied inside of a reaction tube 3. The flow of the material gas inside the reaction tube 3 is set in a direction, parallel to the growth surface of a substrate 14, and the velocity of flow of the material gas inside the reaction tube 3 is set at 2 m/s or less. Thus, ammonia can be fully heated by the delay amount of the velocity of flow, and decomposing efficiency can be improved, and the supply of the nitrogen material to the growth surface of the substrate 14 can be increased, and the evaporation of nitrogen from the III-V nitride compound semiconductor during growth can be suppressed. Also, it is desirable that the inside the reaction tube 3 be pressurized.

    Abstract: PROBLEM TO BE SOLVED: To enhance uniformity concerning the light intensity distribution of an illumination optical system and also to restrain the lowering of efficiency caused by interference so as to control the lowering of luminance to the minimum. SOLUTION: In the prism element 1 used for uniformizing the light intensity distribution, a second surface 2_2 being a polarized light branching surface is arranged between a first surface 2_1 and a third surface 2_3 being reflection surfaces. The first and the third surfaces are arranged in parallel or nearly in parallel with each other, and incident light is emitted passing through an optical path where it is branched by the second surface 2_2 after it is reflected by the first surface 2_1 and an optical path where it is directly branched by the second surface 2_2. The luminous fluxes divided into four in the prism element 1 are composed, thereby obtaining averaged light quantity distribution. COPYRIGHT: (C)2007,JPO&INPIT
