| 英文摘要 | PURPOSE:To obtain a technology through which light emitting or photodetecting components are disposed quite densely in an element where a plurality of light emitting or photodetecting components are integrated on the same substrate by providing the second conductivity type impurity regions of the light emitting or photodetecting components each having a diode structure so that the above impurity regions are independent of each other and they are able to establish respective potential gradients individually. CONSTITUTION:A plurality of the second conductivity type impurity regions 3 are formed on a semi-insulating or the first conductivity type substrate 4 and a plurality of light emitting components 1 having a diode structure consisting of the second conductivity type semiconductor connecting to the second conductivity type impurity regions 3 and the first conductivity type semiconductor which is adjacent to the above second conductivity type semiconductor are integrated in an element. In this element, the foregoing second conductivity type impurity regions 3 are provided so that the regions are independent of each other and they are able to establish respective potential gradients individually. For example, the light emitting components 1 which are disposed in an array form are divided into two separate groups for each component and anodes in each group are connected one another for each p type diffusion layer 3 which is formed at a lower part of each light emitting component Then electrodes which provide electric potential from the outside for the above anodes respectively are shown at A and B. Cathodes of the light emitting components which are adjacent to the anodes are connected to one bonding pad 2 by making every two cathodes form a set. |
