  • Means for a self-aligned multilayer laser epitaxy structure device
    Patent number: 4665525
    Abstract: A method of forming the proper metallization contacts in a multilayer epitaxy laser device is provided. By selecting the proper crystal plane orientation in etching nonplanar features like channels for the device, a differential etch rate in a free-etch can be effected to remove only selected portions of the top layer and to provide self-alignment in the metallization process.
    Type: Grant
    Filed: May 16, 1986
    Date of Patent: May 12, 1987
    Assignee: Hewlett-Packard Company
    Inventors: Donald E. Ackley, Reinhart W. H. Engelmann, Teruko K. Inouye
