IPC: G02B9/64
Filed: 1990-10-25
Abstract: PURPOSE:To obtain a large-diameter lens by satisfying specific conditions with the refraction factor distribution type lens constituted of multiple lenses containing at least one lens with the refraction factor spherically distributed centering on a specific point on the optical axis. CONSTITUTION:This is a refraction factor distribution type spherical lens constituted of multiple lenses containing at least one lens with the refraction factor spherically distributed centering on a point on the optical axis. This lens is expressed by the equation I, where N is the refraction factor of homogeneous glass serving as a base, (r) is the radius of a sphere with the spherically distributed refraction factor, X0 is the distribution center position of the spherically distributed refraction factor measured from the face on the object side of the refraction factor distribution type lens, (b) is the distance where the refraction factor measured from the distribution center position becomes N1, N2,... are primary, secondary... coefficients, and D is the thickness on the optical axis of the refraction factor distribution type lens. When a curvature is applied to the glass serving as a base material, the spherical refraction factor distribution along the curvature is obtained, thus the large-diameter lens can be obtained.

IPC: H01L21/331
Filed: 1989-11-04
Abstract: PURPOSE:To reduce a base resistance even if the width of the base is narrowed by adding specific mol% of Sb atoms to As atoms of group V forming GaAlAs or InGaAlAs together with Be atoms of specific atoms/cm<3> during a growing step CONSTITUTION:0.5-10mol% of Sb atoms 5 are added to As of V group atoms for forming GaAlAs or InGaAlAs together with Be atoms 1 of 5X10<19>-5X10<20> atoms/cm<3> during a growing step. When the Sb having large atomic radius is doped, the Sb is introduced to the position of V group element at random to alleviate a distortion generated by the Be having small atomic radius. Accordingly, the Be atoms 1 are stood still in a lower energy state, and abnormal increase of a diffusion coefficient is reduced. Thus, even if an epitaxial layer having different conductivity type from that is adjacently grown, the Be is diffused to eliminate the damage of a predetermined impurity profile. In this manner, a base resistance can be reduced by a narrow base width.
