Publication number: 20230127051Abstract: The present disclosure provides a gallium oxide semiconductor structure, a vertical gallium oxide-based power device, and a preparation method. An unintentionally doped gallium oxide layer (110) is transferred to a highly doped and highly thermally conductive heterogeneous substrate (200) by bonding and thinning; then a heavily doped gallium oxide layer (120) is formed on the gallium oxide layer by treating and ion implantation, thereby preparing the gallium oxide semiconductor structure including the heterogeneous substrate (200), the gallium oxide layer (110), and the heavily doped gallium oxide layer (120) stacked in sequence.
