Abstract
A semiconductor structure includes a group IV substrate and a patterned group III-V device over the group IV substrate. Precursor stacks having at least one precursor metal are situated over at least one portion of the patterned group III-V device. A blanket dielectric layer is situated over the patterned group III-V device. Contact holes in the blanket dielectric layer are situated over each precursor stack. A filler metal is situated in each contact hole and over each precursor stack. The patterned group III-V device can be optically and/or electrically connected to group IV devices in the group IV substrate. Additional contact holes in the blanket dielectric layer can be situated over the group IV devices and filled with the filler metals.
