  • Method of making monolithic integrated optoelectronic modules
    Patent number: 5075239
    Abstract: A method of making monolithic integrated optoelectronic modules in which passivation and electric isolation of the individual components are achieved with an epitaxially deposited, semi-insulating (SI) indium phosphide layer. Instead of a semi-insulating substrate, a conducting substrate can therefore be used, which results in a better lattice structure of the deposited layers.
