  • Semiconductor on diamond substrate, precursor for use in preparing a semiconductor on diamond substrate, and methods for making the same
    Patent number: 11791157
    Abstract: The invention provides a method 100 of manufacturing a precursor 105a for use in manufacturing a semiconductor-on-diamond substrate 110, the method comprising: a) starting with a base substrate 112; b) forming a sacrificial carrier layer 114 on the base substrate, the sacrificial carrier layer comprising a single-crystal semiconductor; c) forming a single-crystal nucleation layer 116 on the sacrificial carrier layer, the single-crystal nucleation layer arranged to nucleate diamond growth; and d) forming a device layer 118 on the single-crystal nucleation layer, the device layer comprising a single-crystal semiconductor layer or multiple single-crystal semiconductor layers.
